the big bang..


 

THE BIG BANG: 

It sure was BIG!! 

The Hubble Telescope's deepest view of the universe teaches us about the beginning


INTRODUCTION 

We certainly know that our universe exists, however, this knowledge alone has not satisfied mankind's quest for further understanding. Our curiosity has led us to question our place in this universe and furthermore, the place of the universe itself. Throughout time we have asked ourselves these questions: How did our universe begin? How old is our universe? How did matter come to exist? Obviously, these are not simple questions and throughout our brief history on this planet much time and effort has been spent looking for some clue. Yet, after all this energy has been expended, much of what we know is still only speculation. 
We have, however, come a long way from the mystical beginnings of the study of cosmology and the origins of the universe. Through the understandings of modern science we have been able to provide firm theories for some of the answers we once called hypotheses. True to the nature of science, a majority of these answers have only led to more intriguing and complex questions. It seems to be inherent in our search for knowledge that questions will always continue to exist. 
Although in this short chapter it will be impossible to tackle all of the questions concerning the creation of everything we know as reality, an attempt will be made to address certain fundamental questions of our being. It will be important to keep in mind that all of this information is constantly being questioned and reevaluated in order to understand the universe more clearly. For our purposes, through an examination of what is known about the Big Bang itself, the age of the universe, and the synthesis of the first atoms, we believe that we can begin to answer several of these key questions. 

THE BIG BANG

One of the most persistently asked questions has been: How was the universe created? Many once believed that the universe had no beginning or end and was truly infinite. Through the inception of the Big Bang theory, however,no longer could the universe be considered infinite. The universe was forced to take on the properties of a finite phenomenon, possessing a history and a beginning. 
About 15 billion years ago a tremendous explosion started the expansion of the universe. This explosion is known as the Big Bang. At the point of this event all of the matter and energy of space was contained at one point. What exisisted prior to this event is completely unknown and is a matter of pure speculation. This occurance was not a conventional explosion but rather an event filling all of space with all of the particles of the embryonic universe rushing away from each other. The Big Bang actually consisted of an explosion of space within itself unlike an explosion of a bomb were fragments are thrown outward. The galaxies were not all clumped together, but rather the Big Bang lay the foundations for the universe. 
The origin of the Big Bang theory can be credited to Edwin Hubble. Hubble made the observation that the universe is continuously expanding. He discovered that a galaxys velocity is proportional to its distance. Galaxies that are twice as far from us move twice as fast. Another consequence is that the universe is expanding in every direction. This observation means that it has taken every galaxy the same amount of time to move from a common starting position to its current position. Just as the Big Bang provided for the foundation of the universe, Hubbles observations provided for the foundation of the Big Bang theory. 
Since the Big Bang, the universe has been continuously expanding and, thus, there has been more and more distance between clusters of galaxies. This phenomenon of galaxies moving farther away from each other is known as the red shift. As light from distant galaxies approach earth there is an increase of space between earth and the galaxy, which leads to wavelengths being stretched. 
In addition to the understanding of the velocity of galaxies emanating from a single point, there is further evidence for the Big Bang. In 1964, two astronomers, Arno Penzias and Robert Wilson, in an attempt to detect microwaves from outer space, inadvertently discovered a noise of extraterrestrial origin. The noise did not seem to emanate from one location but instead, it came from all directions at once. It became obvious that what they heard was radiation from the farthest reaches of the universe which had been left over from the Big Bang. This discovery of the radioactive aftermath of the initial explosion lent much credence to the Big Bang theory. 
Even more recently, NASAs COBE satellite was able to detect cosmic microwaves eminating from the outer reaches of the universe. These microwaves were remarkably uniform which illustrated the homogenity of the early stages of the universe. However, the satillite also discovered that as the universe began to cool and was still expanding, small fluctuations began to exist due to temperature differences. These flucuatuations verified prior calculations of the possible cooling and development of the universe just fractions of a second after its creation. These fluctuations in the universe provided a more detailed description of the first moments after the Big Bang. They also helped to tell the story of the formation of galaxies which will be discussed in the next chapter. 
The Big Bang theory provides a viable solution to one of the most pressing questions of all time. It is important to understand, however, that the theory itself is constantly being revised. As more observations are made and more research conducted, the Big Bang theory becomes more complete and our knowledge of the origins of the universe more substantial. 

THE FIRST ATOMS

Now that an attempt has been made to grapple with the theory of the Big Bang, the next logical question to ask would be what happened afterward? In the minuscule fractions of the first second after creation what was once a complete vacuum began to evolve into what we now know as the universe. In the very beginning there was nothing except for a plasma soup. What is known of these brief moments in time, at the start of our study of cosmology, is largely conjectural. However, science has devised some sketch of what probably happened, based on what is known about the universe today. 
Immediately after the Big Bang, as one might imagine, the universe was tremendously hot as a result of particles of both matter and antimatter rushing apart in all directions. As it began to cool, at around 10^-43 seconds after creation, there existed an almost equal yet asymmetrical amount of matter and antimatter. As these two materials are created together, they collide and destroy one another creating pure energy. Fortunately for us, there was an asymmetry in favor of matter. As a direct result of an excess of about one part per billion, the universe was able to mature in a way favorable for matter to persist. As the universe first began to expand, this discrepancy grew larger. The particles which began to dominate were those of matter. They were created and they decayed without the accompaniment of an equal creation or decay of an antiparticle. 
As the universe expanded further, and thus cooled, common particles began to form. These particles are called baryons and include photons, neutrinos, electrons and quarks would become the building blocks of matter and life as we know it. During the baryon genesis period there were no recognizable heavy particles such as protons or neutrons because of the still intense heat. At this moment, there was only a quark soup. As the universe began to cool and expand even more, we begin to understand more clearly what exactly happened. 
After the universe had cooled to about 3000 billion degrees Kelvin, a radical transition began which has been likened to the phase transition of water turning to ice. Composite particles such as protons and neutrons, called hadrons, became the common state of matter after this transition. Still, no matter more complex could form at these temperatures. Although lighter particles, called leptons, also existed, they were prohibited from reacting with the hadrons to form more complex states of matter. These leptons, which include electrons, neutrinos and photons, would soon be able to join their hadron kin in a union that would define present-day common matter. 
After about one to three minutes had passed since the creation of the universe, protons and neutrons began to react with each other to form deuterium, an isotope of hydrogen. Deuterium, or heavy hydrogen, soon collected another neutron to form tritium. Rapidly following this reaction was the addition of another proton which produced a helium nucleus. Scientists believe that there was one helium nucleus for every ten protons within the first three minutes of the universe. After further cooling, these excess protons would be able to capture an electron to create common hydrogen. Consequently, the universe today is observed to contain one helium atom for every ten or eleven atoms of hydrogen. 
While it is true that much of this information is speculative, as the universe ages we are able to become increasingly confident in our knowledge of its history. By studying the way in which the universe exists today it is possible to learn a great deal about its past. Much effort has gone into understanding the formation and number of baryons present today. Through finding answers to these modern questions, it is possible to trace their role in the universe back to the Big Bang. Subsequently, by studying the formation of simple atoms in the laboratory we can make some educated guesses as to how they formed originally. Only through further research and discovery will it be possible to completely understand the creation of the universe and its first atomic structures, however, maybe we will never know for sure.

AGE OF THE UNIVERSE

We now have something of a handle on two of the most important quandaries concerning the universe; however, one major question remains. If the universe is indeed finite, how long has it been in existence? Again, science has been able to expand upon what it knows about the universe today and extrapolate a theory as to its age. By applying the common physical equation of distance over velocity equaling time, which again uses Hubbles observations, a fairly accurate approximation can be made. 
The two primary measurements needed are the distance of a galaxy moving away from us and that galaxys red shift. An unsuccessful first attempt was made to find these distances through trigonometry. Scientists were able to calculate the diameter of the Earths orbit around the sun which was augmented through the calculation of the Suns motion through our own galaxy. Unfortunately, this calculation could not be used alone to determine the enormous distance between our galaxy and those which would enable us to estimate the age of the universe because of the significant errors involved. 
The next step was an understanding of the pulsation of stars. It had been observed that stars of the same luminosity blinked at the same rate, much like a lighthouse could work where all lighthouses with 150,000 watt light bulbs would rotate every thirty seconds and those with 250,000 watt light bulbs would rotate every minute. With this knowledge, scientists assumed that stars in our galaxy that blinked at the same rate as stars in distant galaxies must have the same intensity. Using trigonometry, they were able to calculate the distance to the star in our galaxy. Therefore, the distance of the distant star could be calculated by studying the difference in their intensities much like determining the distance of two cars in the night. Assuming the two cars headights had the same intensity, it would be possible to infer that the car whose headlights appeared dimmer was farther away from the observer than the other car whose headlights would seem brighter. Again, this theory could not be used alone to calculate distance of the most far-away galaxies. After a certain distance it becomes impossible to distinguish individual stars from the galaxies in which they exist. Because of the large red shifts in these galaxies a method had to be devised to find distance using entire galaxy clusters rather than stars alone. 
By studying the sizes of galaxy cluster that are near to us, scientists can gain an idea of what the sizes of other clusters might be. Consequently, a prediction can be made about their distance from the Milky Way much in the same way the distance of stars was learned. Though a calculation involving the supposed distance of the far-off cluster and its red shift, a final estimation can be made as to how long the galaxy has been moving away from us. In turn, this number can be used inversely to turn back the clock to a point when the two galaxies were in the same place at the same time, or, the moment of the Big Bang. The equation generally used to show the age of the universe is shown here: 
(distance of a particular galaxy) / (that galaxys velocity) = (time)
or 
4.6 x 10^26 cm / 1 x 10^9 cm/sec = 4.6 x 10^17 sec 
This equation, equaling 4.6 x 10^17 seconds, comes out to be approximately fifteen billion years. This calculation is almost exactly the same for every galaxy that can be studied. However, because of the uncertainties of the measurements produced by these equations, only a rough estimate of the true age of the universe can be fashioned. While finding the age of the universe is a complicated process, the achievement of this knowledge represents a critical step in our understanding. 

NOW WHAT?

In summary, we have made a first attempt at explaining the answers that science has revealed about our universe. Our understanding of the Big Bang, the first atoms and the age of the universe is obviously incomplete. As time wears on, more discoveries are made, leading to infinite questions which require yet more answers. Unsatisfied with our base of knowledge research is being conducted around the world at this very moment to further our minimal understanding of the unimaginably complex universe. 
Since its conception, the theory of the Big Bang has been constantly challenged. These challenges have led those who believe in the theory to search for more concrete evidence which would prove them correct. From the point at which this chapter leaves off, many have tried to go further and several discoveries have been made that paint a more complete picture of the creation of the universe. 
Recently, NASA has made some astounding discoveries which lend themselves to the proof of the Big Bang theory. Most importantly, astronomers using the Astro-2 observatory were able to confirm one of the requirements for the foundation of the universe through the Big Bang. In June, 1995, scientists were able to detect primordial helium, such as deuterium, in the far reaches of the universe. These findings are consistent with an important aspect of the Big Bang theory that a mixture of hydrogen and helium was created at the beginning of the universe. 
In addition, the Hubble telescope, named after the father of Big Bang theory, has provided certain clues as to what elements were present following creation. Astronomers using Hubble have found the element boron in extremely ancient stars. They postulate that its presence could be either a remnant of energetic events at the birth of galaxies or it could indicate that boron is even older, dating back to the Big Bang itself. If the latter is true, scientists will be forced once again to modify their theory for the birth of the universe and events immediately afterward because, according to the present theory, such a heavy and complex atom could not have existed.
In this manner we can see that the research will never be truly complete. Our hunger for knowledge will never be satiated. So to answer the question, what now, is an impossibility. The path we take from here will only be determined by our own discoveries and questions. We are engaged in a never-ending cycle of questions and answers where one will inevitably lead to the other.

DEEP THOUGHTS

It is extremely difficult to separate this subject of science from daily existential pondering. Everyone at some point in time has grappled with the question of why we are here? Some have found refuge in the sheer philosophic nature of this question while others have taken a more scientific approach. These particular wanderers have taken the question to a higher level, concentrating not only on human existence but the existence of everything we know as real. 
If you sit and try to imagine the whole of the entire universe it would be mind-boggling. However, science has now told us that the universe is, in fact, finite, with a beginning, a middle, and a future. It is easy to get caught up in the large scale of the issue in discussing years by the billions, yet, this time still passes. As we travel through our own lives here on Earth, we also travel through the life of our universe. 
In this chapter, we have made some attempts to explain this journey. It is odd that we will never truly know how it began. We can only speculate and give our best guess. Through our own devices we have been able to produce evidence that these guesses are close to the truth. But centuries from now, will the human race compare us to those who once thought of the Earth as the center of the universe?

THE ORIGIN OF THE UNIVERSE

The origin of the universe is described in the Qur'an in the following verse:
"He is the Originator of the heavens and the earth." (The Qur'an, 6:101)
This information given in the Qur'an is in full agreement with the findings of contemporary science. The conclusion that astrophysics has reached today is that the entire universe, together with the dimensions of matter and time, came into existence as a result of a great explosion that occurred in no time. This event, known as "The Big Bang" proved that the universe was created from nothingness as the result of the explosion of a single point. Modern scientific circles are in agreement that the Big Bang is the only rational and provable explanation of the beginning of the universe and of how the universe came into being.
Before the Big Bang, there was no such thing as matter. From a condition of non-existence in which neither matter, nor energy, nor even time existed, and which can only be described metaphysically, matter, energy, and time were all created. This fact, only recently discovered by modern physics, was announced to us in the Qur'an 1,400 years ago.

The sensitive sensors on board the COBE space satellite which was launched by NASA in 1992, captured evidentiary remnants of the Big Bang. This discovery served as evidence for the Big Bang, which is the scientific explanation of the fact that the universe was created from nothing.

THE EXPANSION OF THE UNIVERSE


Edwin Hubble with his giant telescope
In the Qur'an, which was revealed 14 centuries ago at a time when the science of astronomy was still primitive, the expansion of the universe was described like this:
"And it is We who have constructed the heaven with might, and verily, it is We who are steadily expanding it." (The Qur'an, 51:47)
The word "heaven", as stated in this verse, is used in various places in the Qur'an with the meaning of space and universe. Here again, the word is used with this meaning. In other words, in the Qur'an it is revealed that the universe "expands". And this is the very conclusion that science has reached today.

From the moment of the big bang, the universe has been constantly expanding at a great speed. Scientists compare the expanding universe to the surface of a balloon that is inflated.
Until the dawn of the 20th century, the only view prevailing in the world of science was that "the universe has a constant nature and it has existed since infinite time". The research, observations, and calculations carried out by means of modern technology, however, have revealed that the universe in fact had a beginning, and that it constantly "expands".
At the beginning of the 20th century, the Russian physicist Alexander Friedmann and the Belgian cosmologist Georges Lemaitre theoretically calculated that the universe is in constant motion and that it is expanding.
This fact was proved also by observational data in 1929. While observing the sky with a telescope, Edwin Hubble, the American astronomer, discovered that the stars and galaxies were constantly moving away from each other. A universe where everything constantly moves away from everything else implied a constantly expanding universe. The observations carried out in the following years verified that the universe is constantly expanding. This fact was explained in the Qur'an when that was still unknown to anyone. This is because the Qur'an is the word of God, the Creator, and the Ruler of the entire universe.
SEPERATION OF THE HEAVENS AND THE EARTH
The picture represents the Big Bang, which revealed once again that God created the universe from nothingness. The Big Bang is a theory that has been proven with scientific evidence. Although some scientists tried to advance alternative theories against the Big Bang, scientific evidence caused the theory to be completely accepted by the scientific community.
Another verse about the creation of the heavens is as follows:
"Do not the Unbelievers see that the heavens and the earth were joined together (as one unit of creation), before We clove them asunder, and We made from water every living thing. Will they not then believe?" (The Qur'an, 21:30)
The word ratq translated as "sewn to" means "mixed in each, blended" in Arabic dictionaries. It is used to refer to two different substances that make up a whole. The phrase "we unstitched" is the verb fataqa in Arabic and implies that something comes into being by tearing apart or destroying the structure of ratq. The sprouting of a seed from the soil is one of the actions to which this verb is applied.
Let us take a look at the verse again with this knowledge in mind. In the verse, sky and earth are at first subject to the status of ratq. They are separated (fataqa) with one coming out of the other. Intriguingly, when we remember the first moments of the Big Bang, we see that a single point included all the matter in the universe. In other words, everything, including "the heavens and earth" which were not created yet, were included in this point in a condition of ratq. This point exploded violently, causing its matter to fataqa and in the process created the structure of the whole universe.
When we compare the expressions in the verse with scientific findings, we see that they are in perfect agreement with each other. Interestingly enough, these findings were not arrived at until the 20th century.
ORBITS
 

While referring to the Sun and the Moon in the Qur'an, it is emphasized that each moves in a definite orbit.
"It is He Who created the night and the day, and the sun and the moon. They swim along, each in an orbit. " (The Qur'an, 21:33)
It is mentioned in another verse, too, that the Sun is not static but moves in a definite orbit:
"And the sun runs to its resting place. That is the decree of the Almighty, the All-Knowing. " (The Qur'an, 36:38)
These facts communicated in the Qur'an have been discovered by astronomical observations in our age. According to the calculations of experts on astronomy, the Sun is traveling at the enormous speed of 720,000 kilometers an hour in the direction of the star Vega in a particular orbit called the Solar Apex. This means that the sun travels roughly 17,280,000 kilometers a day. Along with the Sun, and all planets and satellites within the gravitational system of the Sun also travel the same distance. In addition, all the stars in the universe are in a similar planned motion.
Like many other comets in the universe, Halley's comet, seen above, also moves in a planned orbit. It has a specific orbit and it moves in this orbit in a perfect harmony with other celestial bodies.
That the entire universe is full of paths and orbits such as this one, is written in the Qur'an as follows:
"By the sky full of paths and orbits." (The Qur'an, 51:7)
There are about 200 billion galaxies in the universe, consisting of nearly 200 billion stars in each. Most of these stars have planets, and most of those planets have satellites. All of these heavenly bodies move in very precisely computed orbits. For millions of years, each has been "swimming" along in its own orbit in perfect harmony and order with all the others. Moreover, many comets also move along in the orbits determined for them.
The orbits in the universe do not only belong to celestial bodies. The galaxies also travel at enormous speeds in computed, planned orbits. During these movements, none of these celestial bodies cuts across another's path, or collides with another.
Surely at the time the Qur'an was revealed, mankind did not possess today's telescopes or advanced observation technologies to observe millions of kilometres of space, nor the modern knowledge of physics or astronomy. Therefore, at that time, it was not possible to determine scientifically that space is "full of paths and orbits" as stated in the verse. However, this was openly declared to us in the Qur'an that was revealed at that time:-because the Qur'an is the word of God.
THE ROUNDNESS OF THE EARTH
 
"He has created the Heavens and the Earth for Truth. He wraps the night up in the day, and wraps the day up in the night." (The Qur'an, 39:5)
In the Qur'an, the words used for describing the universe are quite remarkable. The Arabic word that is translated as "to wrap" in the above verse is "takwir". In English, it means "to make one thing lap over another, folded up as a garment that is laid away". (For instance, in Arabic dictionaries this word is used for the action of wrapping one thing around another, in the way that a turban is put on.)
The information given in the verse about the day and the night wrapping each other up includes accurate information about the shape of the world. This can be true only if the earth is round. This means that in the Qur'an, which was revealed in the 7th century, the roundness of the world was hinted at.
It should be remembered, however, that the understanding of astronomy of the time perceived the world differently. It was then thought that the world was a flat plane and all scientific calculations and explanations were based on this belief. The verses of the Qur'an, however, include information that we have learned only in the past century. Since the Qur'an is God's word, the most correct words were used in it when it comes to describing the universe.

ROTECTED ROOF


T
HE SECRET IN THE IRON

Iron ingot
Iron is one of the elements highlighted in the Qur'an. In Sura Hadid, meaning Iron, we are informed:

"…And We sent down iron in which there lies great force and which has many uses for mankind...." (The Qur'an, 57:25)
The word "sent down," particularly used for iron in the verse, could be thought of having a metaphorical meaning to explain that iron has been given to benefit people. But when we take into consideration the literal meaning of the word, which is, "being physically sent down from the sky", we realize that this verse implies a very significant scientific miracle.
This is because modern astronomical findings have disclosed that the iron found in our world has come from the giant stars in outer space.
The heavy metals in the universe are produced in the nuclei of big stars. Our solar system, however, does not possess a suitable structure for producing iron on its own. Iron can only be produced in much bigger stars than the Sun, where the temperature reaches a few hundred million degrees. When the amount of iron exceeds a certain level in a star, the star can no longer accommodate it, and eventually it explodes in what is called a "nova" or a "supernova". As a result of this explosion, meteors containing iron are scattered around the universe, and they move through the void until attracted by the gravitational force of a celestial body.
All this shows that iron did not form on the Earth, but was carried from exploding stars in space via meteors, and was "sent down to earth", in exactly the same way as stated in the verse: It is clear that this fact could not have been scientifically known in the 7th century, when the Qur'an was revealed.

This illustration shows meteors that are about to crash into the earth. The celestial bodies wandering in space could pose a serious threat to the Earth. Yet, God, He Who creates most perfectly, has made the atmosphere a protective roof. Thanks to this special protection, most meteoroids do not harm the Earth, as they fall to pieces in the atmosphere.
In the Qur'an, God calls our attention to a very interesting attribute of the sky:
"We made the sky a preserved and protected roof yet still they turn away from Our Signs.." (The Qur'an, 21:32)
This attribute of the sky has been proved by scientific research carried out in the 20th century.
The atmosphere surrounding the earth serves crucial functions for the continuity of life. While destroying many meteors big and small as they approach the earth, it prevents them from falling to earth and harming living things.
In addition, the atmosphere filters the light rays coming from space that are harmful to living things. Interestingly, the atmosphere lets only harmless and useful rays- visible light, near ultraviolet light, and radio waves pass through. All of this radiation is vital for life. Near ultraviolet rays, which are only partially let in by the atmosphere, are very important for the photosynthesis of plants and for the survival of all living beings. The majority of the intense ultraviolet rays emitted from the sun are filtered out by the ozone layer of the atmosphere and only a limited-and essential-part of the ultraviolet spectrum reaches the Earth.
Most people looking at the sky do not think about the protective aspect of the atmosphere. They almost never think what kind of a place the world would be like if this structure did not exist. The above photo belongs to a giant crater caused by a meteor that fell in Arizona, in the USA. If the atmosphere did not exist, millions of meteoroids would fall to the Earth and the Earth would become an inhabitable place. Yet, the protective aspect of the atmosphere allows living things to survive in safety. This is certainly God's protection of people, and a miracle proclaimed in the Qur'an.
The protective function of the atmosphere does not end here. The atmosphere also protects the earth from the freezing cold of the space, which is about minus 270o C.
It is not only the atmosphere that protects the Earth from harmful effects. In addition to the atmosphere, the Van Allen Belt, a layer caused by the magnetic field of the Earth, also serves as a shield against the harmful radiation that threatens our planet. This radiation, which is constantly emitted by the Sun and other stars, is deadly to living things. If the Van Allen belt did not exist, the massive outbursts of energy called solar flares that frequently occur in the Sun would destroy all life on Earth.
Dr. Hugh Ross has this to say on the importance of Van Allen Belts to our lives:
In fact, the Earth has the highest density of any of the planets in our Solar System. This large nickel-iron core is responsible for our large magnetic field. This magnetic field produces the Van-Allen radiation shield, which protects the Earth from radiation bombardment. If this shield were not present, life would not be possible on the Earth. The only other rocky planet to have any magnetic field is Mercury - but its field strength is 100 times less than the Earth's. Even Venus, our sister planet, has no magnetic field. The Van-Allen radiation shield is a design unique to the Earth. (http://www.jps.net/bygrace/index. html Taken from Big Bang Refined by Fire by Dr. Hugh Ross, 1998. Reasons To Believe, Pasadena, CA.)
The energy transmitted in just one of these bursts detected in recent years was calculated to be equivalent to 100 billion atomic bombs similar to the one dropped on Hiroshima. Fifty-eight hours after the burst, it was observed that the magnetic needles of compasses displayed unusual movement and 250 kilometers above the earth's atmosphere, the temperature suddenly increased to 2,500o C.
In short, a perfect system is at work high above the Earth. It surrounds our world and protects it against external threats. Scientists only learned about it recently, yet centuries ago, God informed us in the Qur'an of the world's atmosphere functioning as a protective shield.
The energy released in a Sun burst is so powerful that the human mind would hardly comprehend it: A single burst is equivalent to 100 billion atomic bombs similar to the one dropped on Hiroshima. The world is protected from the destructive effects of this energy by the atmosphere and the Van Allen Belts.
As we move from the Earth, which is perfectly fitted for human life, beyond the atmosphere into the space, we come across a freezing cold. The world is protected from the freezing cold of space, which is around -270 degrees, by the help of the atmosphere.
The magnetosphere layer, formed by the magnetic field of the Earth, serves as a shield protecting the earth from celestial bodies, harmful cosmic rays and particles. In the above picture, this magnetosphere layer, which is also named Van Allen Belts, is seen. These belts at thousands of kilometres above the earth protect the living things on the Earth from the fatal energy that would otherwise reach it from space.
THE LAYERS OF THE ATMOSPHERE
The Earth has all the attributes that are needed for life. One of them is the atmosphere, which serves as a shield protecting living things. Today, it is an established fact that the atmosphere is made up of different layers lying on top of one another. Just as it is described in the Qur'an, the atmosphere is made up of exactly seven layers. This is certainly one of the miracles of the Qur'an.
One fact about the universe revealed in the verses of the Qur'an is that the sky is made up of seven layers.
"It is He Who created everything on the earth for you and then directed His attention up to heaven and arranged it into seven regular heavens. He has knowledge of all things." (The Qur'an, 2:29)
"Then He turned to heaven when it was smoke. In two days He determined them as seven heavens and revealed, in every heaven, its own mandate." (The Qur'an, 41:12)
The word "heavens", which appears in many verses in the Qur'an, is used to refer to the sky above the Earth, as well as the entire universe. Given this meaning of the word, it is seen that the Earth's sky, or the atmosphere, is made up of seven layers.
Indeed, today it is known that the world's atmosphere consists of different layers that lie on top of each other. Furthermore, it consists, just as is described in the Qur'an, of exactly seven layers. In a scientific source, the subject is described as follows:
Scientists have found that the atmosphere consists of several layers. The layers differ in such physical properties as pressure and the types of gasses. The layer of the atmosphere closest to Earth is called the TROPOSPHERE. It contains about 90% of the total mass of the atmosphere. The layer above the troposphere is called the STRATOSPHERE. The OZONE LAYER is the part of the stratosphere where absorption of ultraviolet rays occurs. The layer above the stratosphere is called the MESOSPHERE. The THERMOSPHERE lies above the mesosphere. The ionized gases form a layer within the thermosphere called the IONOSPHERE. The outermost part of Earth's atmosphere extends from about 480 km out to 960 km. This part is called the EXOSPHERE. (Carolyn Sheets, Robert Gardner, Samuel F. Howe; General Science, Allyn and Bacon Inc. Newton, Massachusetts, 1985, s. 319-322)
If we count the number of layers cited in this source, we see that the atmosphere consists of exactly seven layers, just as stated in the verse.
1. Troposphere
2. Stratosphere
3. Ozonosphere
4. Mesosphere
5. Thermosphere
6. Ionosphere
7. Exosphere
Another important miracle on this subject is mentioned in the statement "(He) revealed, in every heaven, its own mandate.", in verse 12 of Sura Fussilet. In other words, in the verse, God states that He assigned each heaven its own duty. Truly, as seen in previous chapters, each one of these layers has vital duties for the benefit of human kind and all other living things on the Earth. Each layer has a particular function, ranging from forming rain to preventing harmful rays, from reflecting radio waves, to averting the harmful effects of meteors.
One of these functions, for example, is stated in a scientific source as follows:
Earth's atmosphere has 7 layers. The lowest layer is called troposphere. Rain, snow and wind only take place in the troposphere. (http://muttley.ucdavis.edu/Book/Atmosphere/beginner/layers-01.html)
It is a great miracle that these facts, which could not possibly be discovered without the technology of the 20th century, were explicitly stated by the Qur'an 1,400 years ago.
14 centuries ago, when the sky was believed to be one unified body, the Qur'an miraculously stated that it consisted of layers, and what is more, "seven" layers. Modern science, on the other hand, discovered the fact that the atmosphere surrounding the Earth is made up of "seven" basic layers only very recently.


THE FUNCTION OF MOUNTAINS
THE SOLAR SYSTEM

The solar system is one of the most wonderful examples of this beautiful harmony to be witnessed. There are nine planets with fifty-four known satellites and an unknown number of smaller bodies. The major planets counting outward from the sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. Earth is the only one on which life is known to exist. It is surely the only one on which human beings can live and survive unaided thanks to abundant land and water and to a breathable atmosphere. 
In the structure of the solar system, we encounter another beautiful example of equilibrium: the balance between a planet's centrifugal force countered by the gravitational attraction of its primary. (In astronomy, a primary is something that another body revolves about. Earth's primary is the sun; the moon's primary is Earth.) Without this balance, everything in the solar system would fly off into the chilling depths of outer space. The balance between these two forces results in paths (orbits) that the planets and other bodies follow around their primaries. If a body moved at too slow a speed, it would plunge into the primary; if it moved at too fast a speed, the primary would be unable to hold onto it, and it would fly off into space. Instead, every body moves at just the right speed to keep it in orbit. Moreover, this equilibrium has to be different for each body because the distance of planets to the sun differs. So do their masses. Therefore, they have to have different orbital speeds not to plunge into the sun or not to fly off into space.
Materialist astronomy holds that the origin and survival of the solar system can be explained by coincidence. Over the last three centuries, many of its adherents have speculated on how this marvelous order should have come to pass and they have failed to get anywhere. To a materialist, the equilibrium and order of the solar system are inexplicable mysteries.
Astronomers like Kepler and Galileo, among the first to discover this superlative equilibrium, acknowledged it as a deliberate design and a sign of divine intervention in the whole universe. Isaac Newton, recognized as one of the greatest scientific minds of all times, once wrote:
This most elegant system of suns, planets, and comets could arise from the purpose and sovereignty of an intelligent and mighty being…He rules them all, not as a soul but as a sovereign lord of all things, and because of His sovereignty He is commonly called "Lord God Almighty."1


With extensions that mountains extend out towards under the ground as well as over the ground, they clench different plates of the earth together like a peg. The Earth's crust consists of plates that are in constant motion. This clenching property of mountains prevents shocks to a great extent, by fixing the earth's crust, which has a very movable structure.
The Qur'an draws attention to a very important geological function of mountains.
"We placed firmly embedded mountains on the earth, so it would not move under them…" (The Qur'an, 21:31)
As we have noticed, it is stated in the verse that mountains have the function of preventing shocks in the Earth.
This fact was not known by anyone at the time the Qur'an was revealed. It was in fact brought to light only recently as a result of the findings of modern geology.
According to these findings, mountains emerge as a result of the movements and collisions of massive plates forming the Earth's crust. When two plates collide, the stronger one slides under the other, the one on the top bends and forms heights and mountains. The layer beneath proceeds under the ground and makes a deep extension downward. That means that mountains have a portion stretching downwards, as large as their visible parts on the Earth.
In a scientific text, the structure of mountains is described as follows:
Where continents are thicker, as in mountain ranges, the crust sinks deeper into the mantle. (General Science, Carolyn Sheets, Robert Gardner, Samuel F. Howe; Allyn and Bacon Inc. Newton, Massachusetts, 1985, s. 305)
In a verse, this role of the mountains is pointed out by a comparison with "pegs":
"Have We not made the earth as a bed and the mountains its pegs?" (The Qur'an, 78:6-7)
Mountains, in other words, clench the plates in the Earth's crust together by extending above and beneath the Earth's surface at the conjunction points of these plates. In this way, they fix the Earth's crust, and prevent it from drifting over the magma stratum or among its plates. Briefly, we may liken mountains to nails that keep pieces of wood together.
This fixing function of the mountains is described in scientific literature by the term "isostasy". Isostasy means the following:
Isostasy: general equilibrium in the Earth's crust maintained by a yielding flow of rock material beneath the surface under gravitational stress. (Webster's New Twentieth Century Dictionary, 2. edition "Isostasy", New York, s. 975)
This vital role of mountains, that was discovered by modern geology and seismic research, was revealed in the Qur'an centuries ago as an example of the supreme wisdom in God's creation.
"We placed firmly embedded mountains on the earth, so it would not move under them..." (The Qur'an, 21:31)
THE FECUNDATING WINDS


The picture above shows the stages in the formation of a wave. Waves are formed by the wind blowing above the surface of the water. With the wind, water particles start to move in a circular motion. This movement soon forms waves, one after the other, and bubbles formed by the waves spread in the air. This is the first stage in the formation of rain. This process is declared in the verse as "We send the fecundating winds and then cause water to descend from the sky."
In one verse of the Qur'an, the "fecundating" characteristic of the winds, and the formation of rain as a result are mentioned.
"And We send the fecundating winds, then cause water to descend from the sky, therewith providing you with water in abundance." (The Qur'an, 15:22)
In this verse, it is pointed out that the first stage in the formation of rain is wind. Until the beginning of the 20th century, the only relationship between the wind and the rain that was known, was that the wind drove the clouds. However, modern meteorological findings have demonstrated the "fecundating" role of the wind in the formation of rain.
This fecundating function of the wind works in the following way:
On the surface of oceans and seas, countless air bubbles form because of the water's foaming action. The moment these bubbles burst, thousands of tiny particles, with a diameter of just one hundredth of a millimeter, are thrown up into the air. These particles, known as "aerosols", mix with dust carried from the land by the wind, and are carried to the upper layers of the atmosphere. These particles carried to higher altitudes by winds come into contact with water vapour up there. Water vapour condenses around these particles and turns into water droplets. These water droplets first come together and form clouds, and then fall to the Earth in the form of rain.
As seen, winds "fecundate" the water vapour floating in the air with the particles they carry from the sea, and eventually help the formation of rain clouds.
If winds did not possess this property, water droplets in the upper atmosphere would never form, and there would be no such thing as rain.
The most important point here is that this critical role of the wind in the formation of rain was stated centuries ago in a verse of the Qur'an, at a time when people knew very little about natural phenomena…

THE SEAS NOT MINGLING WITH ONE ANOTHER
One of the properties of seas that has only recently been discovered is related in a verse of the Qur'an as follows:
"He has let loose the two seas, converging together, with a barrier between them they do not break through." (The Qur'an, 55:19-20)
This property of the seas, that they come together yet do not mingle with one another at all, has only very recently been discovered by oceanographers. Because of the physical force called "surface tension", the waters of neighboring seas do not mix. Caused by the difference in the density of their waters, surface tension prevents them from mingling with one another, just as if a thin wall were between them. (Davis, Richard A., Jr. 1972, Principles of Oceanography, Don Mills, Ontario, Addison-Wesley Publishing, s. 92-93.)
There are large waves, strong currents, and tides in the Mediterranean Sea and the Atlantic Ocean. Mediterranean Sea water enters the Atlantic by Gibraltar. But their temperature, salinity, and densities do not change, because of the barrier that separates them.
The interesting side to this is that during a period when people had no knowledge of physics, surface tension, or oceanography; this was revealed in the Qur'an.
DARKNESS IN THE SEAS AND INTERNAL WAVES


Measurements made with today's technology have revealed that between 3 and 30 percent of the sunlight is reflected at the surface of the sea. Then, almost all of the seven colours of the light spectrum are absorbed, one after another, in the first 200 meters, except for blue light (picture at left). Below a depth of 1,000 meters, there is no light at all. (above picture). This scientific fact was pointed out in the verse 40 of Sura Nur in the Qur'an 1,400 years ago..
"Or (the unbelievers' state) are like the darkness of a fathomless sea which is covered by waves above which are waves above which are clouds, layers of darkness, one upon the other. If he puts out his hand, he can scarcely see it. Those God gives no light to, they have no light." (The Qur'an, 24:40)
The general environment in deep seas is described in the book named Oceans:
The darkness in deep seas and oceans is found around a depth of 200 meters and below. At this depth, there is almost no light. Below a depth of 1000 meters there is no light at all. (Elder, Danny; and John Pernetta, 1991, Oceans, London, Mitchell Beazley Publishers, s. 27)
Today, we know about the general structure of the sea, the characteristics of the living things in it, its salinity, as well as the amount of water it contains, its surface area and depth. Submarines and special equipment, developed with modern technology, enable scientists to obtain this information.
Human beings are not able to dive more than 40 meters down without the aid of special equipment. They cannot survive unaided in the deep, dark parts of the oceans, such as at a depth of 200 meters. For these reasons, scientists have only recently been able to discover these detailed pieces of information about seas. However, the statement of "darkness in a deep sea" was used in Sura Nur 1,400 years ago. It is certainly one of the miracles of the Qur'an that such information was given at a time where no equipment to enable man to dive into the depths of the oceans was available.
In addition, the statement in verse 40 of Sura Nur "…like the darkness of a fathomless sea which is covered by waves above which are waves above which are clouds…" draws our attention to another miracle of the Qur'an.
Scientists have recently discovered that there are internal waves, which "occur on density interfaces between layers of different densities." These internal waves cover the deep waters of seas and oceans because deep water has a higher density than the water above it. Internal waves act like surface waves. They can break, just like surface waves. Internal waves cannot be seen by the human eye, but they can be detected by studying temperature or salinity changes at a given location. (Gross, M. Grant; 1993, Oceanography, a View of Earth, 6. edition, Englewood Cliffs, Prentice-Hall Inc., s. 205)
The statements in the Qur'an run absolutely parallel to the above explanation. Without research, one can only see the waves on the surface of the sea. It is impossible for one to know about the internal waves beneath the sea. Yet, in Sura Nur, God draws our attention to another type of wave that occurs in the depths of the oceans. Certainly, this fact, which scientists has discovered very recently, shows once again that the Qur'an is the word of God.
THE PROPORTION OF RAIN
One of the items of information given in the Qur'an about rain is that it is sent down to Earth in due measure. This is mentioned in Sura Zukhruf as follows;
"It is He who sends down water in due measure from the sky by which We bring a dead land back to life. That is how you too will be raised (from the dead)." (The Qur'an, 43:11)
This measured quantity in rain has again been discovered by modern research. It is estimated that in one second, approximately 16 million tons of water evaporates from the Earth. This figure amounts to 513 trillion tons of water in one year. This number is equal to the amount of rain that falls on the Earth in a year. This means that water continuously circulates in a balanced cycle, in a "measure". Life on Earth depends on this water cycle. Even if people used all the available technology in the world, they would not be able to reproduce this cycle artificially.
  
Every year, the amount of water that evaporates and that falls back to the Earth in the form of rain is "constant": 513 trillion tons. This constant amount is declared in the Qur'an by the expression "sending down water in due measure from the sky". The constancy of this quantity is very important for the continuity of the ecological balance, and therefore, life. ago..
THE FORMATION OF RAIN
How rain forms remained a great mystery for a long time. Only after weather radar was invented was it possible to discover the stages by which rain is formed.
According to this, the formation of rain takes place in three stages. First, the "raw material" of rain rises up into the air with the wind. Later, clouds are formed, and finally raindrops appear.
The Qur'an's account of the formation of rain refers exactly to this process. In one verse, this formation is described in this way:
"It is God Who sends the winds which stir up clouds which He spreads about the sky however He wills. He forms them into dark clumps and you see the rain come pouring out from the middle of them. When He makes it fall on those of His slaves He wills, they rejoice" (The Qur'an, 30:48)
The above illustration shows the water droplets being released into the air. This is the first stage in the formation of rain. After that, the water droplets in the newly formed clouds will be suspended in the air and then condense to form rain. All of these stages are related in the Qur'an.
Now, let us examine these three stages outlined in the verse more technically.
FIRST STAGE: "It is God Who sends the winds..."
Countless air bubbles formed by the foaming of the oceans continuously burst and cause water particles to be ejected towards the sky. These particles, which are rich in salt, are then carried away by winds and rise upward in the atmosphere. These particles, which are called aerosols, function as water traps, and form cloud drops by collecting around the water vapour themselves, which rises from the seas as tiny droplets.
SECOND STAGE: ".... which stir up clouds which He spreads about the sky however He wills. He forms them into dark clumps..."
The clouds are formed from water vapour that condenses around the salt crystals or dust particles in the air. Because the water droplets in these clouds are very small (with a diameter between 0.01 and 0.02 mm), the clouds are suspended in the air, and spread across the sky. Thus, the sky is covered in clouds.
THIRD STAGE: "…and you see the rain come pouring our from the middle of them"
The water particles that surround salt crystals and dust particles thicken and form raindrops, so, drops that become heavier than the air leave the clouds and start to fall to the ground as rain.
As we have seen, every stage in the formation of rain is related in the verses of the Qur'an. Furthermore, these stages are explained in exactly the right sequence. Just as with many other natural phenomena on the Earth, God gives the most correct explanation of this phenomenon as well, and made it known to people in the Qur'an centuries before it was discovered.

Small clouds (cumulus clouds) are carried along and joined together by the wind, that is, as the verse says: "…God drives along the clouds, then joins them together …"
In another verse, the following information is given about the formation of rain:
"Have you not seen how God drives along the clouds, then joins them together, then makes them into a stack, and then you see the rain come out of it? And He sends down from the sky mountain masses (of clouds) with cold hail in them, striking with it anyone He wills and averting it from anyone He wills. The brightness of His lightning almost blinds the sight." (The Qur'an, 24:43)
Scientists studying cloud types came across surprising results regarding the formation of rain clouds. Rain clouds are formed and shaped according to definite systems and stages. The formation stages of cumulonimbus, one kind of rain cloud, are these:
1. STAGE, Being driven along: Clouds are carried along, that is, they are driven along, by the wind.
2. STAGE, Joining: Then, small clouds (cumulus clouds) driven along by the wind join together, forming a larger cloud.
3. STAGE, Stacking: When the small clouds join together, updrafts within the larger cloud increase. The updrafts near the centre of the cloud are stronger than those near the edges. These updrafts cause the cloud body to grow vertically, so the cloud is stacked up. This vertical growth causes the cloud body to stretch into cooler regions of the atmosphere, where drops of water and hail formulate and begin to grow larger and larger. When these drops of water and hail become too heavy for the updrafts to support them, they begin to fall from the cloud as rain, hail, etc.(Anthes, Richard A.; John J. Cahir; Alistair B. Fraser; and Hans A. Panofsky, 1981, The Atmosphere, s. 269; Millers, Albert; and Jack C. Thompson, 1975, Elements of Meteorology, s. 141-142)
We must remember that meteorologists have only recently come to know these details of cloud formation, structure and function, by using advanced equipment like planes, satellites, computers etc. It is evident that God has given us a piece of information that could not have been known 1,400 years ago.
(A) Isolated small pieces of clouds (cumulus clouds)
(B) When the small clouds join together, updrafts within the larger cloud increase, and so the cloud is stacked up.
THE MOVEMENTS OF MOUNTAINS
In one verse, we are informed that mountains are not motionless as they seem, but are in constant motion.
"You will see the mountains you reckoned to be solid going past like clouds." (The Qur'an, 27:88)
This motion of the mountains is caused by the movement of the Earth's crust that they are located on. The Earth's crust 'floats' over the mantle layer, which is denser. It was at the beginning of the 20th century when, for the first time in history, a German scientist by the name of Alfred Wegener proposed that the continents of the earth had been attached together when it first formed, but then drifted in different directions, and thus separated as they moved away from each other.
Geologists understood that that Wegener was right only in the 1980s, 50 years after his death. As Wegener pointed out in an article published in 1915, the land masses on the earth were joined together about 500 million years ago. As Wegener pointed out in a 1915 article, the land masses of the earth were joined together some 500 million years ago, and this large mass, called Pangaea, was located in the South Pole.
Approximately 180 million years ago, Pangaea divided into two parts, which drifted in different directions. One of these giant continents was Gondwana, which included Africa, Australia, Antarctica and India. The second one was Laurasia, which included Europe, North America and Asia, except for India. Over the next 150 million years following this separation, Gondwana and Laurasia divided into smaller parts.
These continents that emerged after the split of Pangaea have been constantly moving on the Earth's surface at several centimetres per year, in the meantime changing the sea and land ratios of the Earth.
Discovered as a result of the geological research carried out at the beginning of the 20th century, this movement of the Earth's crust is explained by scientists as follows:
The crust and the uppermost part of the mantle, with a thickness of about 100 kms., are divided into segments called plates. There are six major plates, and several small ones. According to the theory called plate tectonics, these plates move about on Earth, carrying continents and ocean floor with them. Continental motion has been measured at from 1-5 cm per year. As the plates continue to move about, this will produce a slow change in Earth's geography. Each year, for instance, the Atlantic Ocean becomes slightly wider. (Carolyn Sheets, Robert Gardner, Samuel F. Howe; General Science, Allyn and Bacon Inc. Newton, Massachusetts, 1985, s. 30)
There is a very important point to be stated here: God has referred to the motion of mountains as a drifting action in the verse. Today, modern scientists also use the term "Continental Drift" for this motion. (National Geographic Society, Powers of Nature, Washington D.C., 1978, s.12-13)
Unquestionably, it is one of the miracles of the Qur'an that this scientific fact, which has recently been discovered by science, was announced in the Qur'an.

THE RETURNING SKY

The verse 11 of Sura Tarik in the Qur'an, refers to the "returning" function of the sky.
"By Heaven with its cyclical systems." (The Qur'an, 86:11)
This word interpreted as "cyclical" in Qur'an translations also has meanings of "sending back" or "returning".
As known, the atmosphere surrounding the Earth consists of many layers. Each layer serves an important purpose for the benefit of life. Research has revealed that these layers have the function of turning the materials or rays they are exposed to back into space or back down to the Earth. Now let us examine with a few examples of this "recycling" function of the layers encircling the Earth.
The troposphere, 13 to 15 kilometers above the Earth, enables water vapor rising from the surface of the Earth to be condensed and turn back as rain.
The ozone layer, at an altitude of 25 kilometers, reflects harmful radiation and ultraviolet light coming from space and turns both back into space.
The ionosphere, reflects radio waves broadcast from the Earth back down to different parts of the world, just like a passive communications satellite, and thus makes wireless communication, radio, and television broadcasting possible over long distances.
The magnetosphere layer turns the harmful radioactive particles emitted by the Sun and other stars back into space before they reach the Earth.
The fact that this property of the atmosphere's layers, that was onlt demonstrated in the recent past was a


BIG-BANG IS BORN
In its standard form, the big bang theory assumes that all parts of the universe began expanding simultaneously. But how could all the different parts of the universe synchronize the beginning of their expansion? Who gave the command? 
Andre Linde, Professor of Cosmology 1
A century ago, the creation of the universe was a concept that astronomers as a rule ignored. The reason was the general acceptance of the idea that the universe existed in infinite time. Examining the universe, scientists supposed that it was just a conglomeration of matter and imagined that it had no beginning. There was no moment of "creation"–a moment when the universe and everything in it came into being.
This idea of "eternal existence" fit in well with European notions stemming from the philosophy of materialism. This philosophy, originally advanced in the world of the ancient Greeks, held that matter was the only thing that existed in the universe and the universe existed in infinite time and will exist endlessly. This philosophy survived in different forms during Roman times but in the Late Roman Empire and Middle Ages, materialism went into decline as a result of the influence of the Catholic church and Christian philosophy. It was after Renaissance that materialism began to gain broad acceptance among European scholars and scientists, largely because of their devotion to ancient Greek philosophy.
It was Immanuel Kant who, during the European Enlightenment, reasserted and defended materialism. Kant declared that the universe exists for all time and that every probability, however unlikely, should be regarded as possible. Kant's followers continued to defend his idea of an infinite universe along with materialism. By the beginning of 19th century, the idea that the universe had no beginning–that there was never any moment at which it was created–became widely accepted. It was carried into the 20th century through the works of dialectical materialists such as Karl Marx and Friedrich Engels.


The German philosopher Immanuel Kant was the first person to advance the assertion of "the infinite universe" in the New Age. Scientific discoveries, however, invalidated Kant's assertion.
This notion of an infinite universe fit in very well with atheism. It is not hard to see why. To hold that the universe had a beginning could imply that it was created and that, of course requires a creator–that is, Allah. It was much more convenient and safer to circumvent the issue by putting forward the idea that "the universe exists for eternity", even though there was not the slightest scientific basis for making such a claim. Georges Politzer, who espoused and defended this idea in his books published in the early 20th century, was an ardent champion of both Marxism and materialism.
Putting his trust in the validity of the "infinite universe" model, Politzer opposed the idea of creation in his book Principes Fondamentaux de Philosophie when he wrote:
The universe was not a created object, if it were, then it would have to be created instantaneously by God and brought into existence from nothing. To admit creation, one has to admit, in the first place, the existence of a moment when the universe did not exist, and that something came out of nothingness. This is something to which science can not accede. 2
Politzer supposed that science was on his side in his defense of the idea of an infinite universe. In fact, science was to prove that the universe indeed had a beginning. And just as Politzer himself declared, if there is creation then there must also be a creator.

The Expansion of Universe and the Discovery of the Big Bang
The 1920s were important years in the development of modern astronomy. In 1922, the Russian physicist Alexandra Friedman produced computations showing that the structure of the universe was not static and that even a tiny impulse might be sufficient to cause the whole structure to expand or contract according to Einstein's Theory of Relativity. George Lemaitre was the first to recognize what Friedman's work meant. Based on these computations, the Belgian astronomer Lemaitre declared that the universe had a beginning and that it was expanding as a result of something that had triggered it. He also stated that the rate of radiation could be used as a measure of the aftermath of that "something".
The theoretical musings of these two scientists did not attract much attention and probably would have been ignored except for new observational evidence that rocked the scientific world in 1929. That year the American astronomer Edwin Hubble, working at the California Mount Wilson observatory, made one of the most important discoveries in the history of astronomy. Observing a number of stars through his huge telescope, he discovered that their light was shifted towards the red end of the spectrum and, crucially, that this shift was directly related to the distance of the stars from Earth. This discovery shook the very basis of the universe model held until then.
According to the recognized rules of physics, the spectra of light beams travelling towards the point of observation tend towards violet while the spectra of light beams moving away from the point of observation tend towards red. (Just like the fading of a train's whistle as it moves away from the observer) Hubble's observation showed that according to this law, the heavenly bodies were moving away from us. Before long, Hubble made another important discovery; The stars weren't just racing away from Earth; they were racing away from each other as well. The only conclusion that could be derived from a universe where everything moves away from everything else is that the universe constantly "expands".


Edwin Hubble discovered that the universe was expanding. Eventually he found evidence of the "the Big Bang", a cataclysmic event whose discovery forced scientists to abandon the notion of an infinite and eternal universe.
Hubble had found observational evidence for something that George Lemaitre had "prophesized" a short while ago and one of the greatest minds of our age had recognized almost fifteen years earlier. In 1915, Albert Einstein had concluded that the universe could not be static because of calculations based on his recently-discovered theory of relativity (thus anticipating the conclusions of Friedman and Lemaitre). 
Shocked by his findings, Einstein added a "cosmological constant" to his equations in order to "make the answer come out right" because astronomers assured him that the universe was static and there was no other way to make his equations match such a model. Years later, Einstein was to admit that his cosmological constant was the biggest mistake of his career.
Hubble's discovery that the universe was expanding led to the emergence of another model that needed no fiddling around with to make the equations work right. If the universe was getting bigger as time advanced, going back in time meant that it was getting smaller; and if one went back far enough, everything would shrink and converge at a single point. The conclusion to be derived from this model was that at some time, all the matter in the universe was compacted in a single point-mass that had "zero volume" because of its immense gravitational force. Our universe came into being as the result of the explosion of this point-mass that had zero volume. This explosion has come to be called the "the Big Bang" and its existence has repeatedly been confirmed by observational evidence.
There was another truth that the Big Bang pointed to. To say that something has zero volume is tantamount to saying that it is "nothing". The whole universe was created from this "nothing". And furthermore this universe had a beginning, contrary to the view of materialism, which holds that "the universe has existed for eternity".

The "Steady-state" Hypothesis
The Big Bang theory quickly gained wide acceptance in the scientific world due to the clear-cut evidence for it. Nevertheless astronomers who favored materialism and adhered to the idea of an infinite universe that materialism seemingly demanded held out against the Big Bang in their struggle to uphold a fundamental tenet of their ideology. The reason was made clear by the English astronomer Arthur Eddington, who said "Philosophically, the notion of an abrupt beginning to the present order of Nature is repugnant to me".3
Another astronomer who opposed the Big Bang theory was Fred Hoyle. Around the middle of the 20th century he came up with a new model, which he called "steady-state", that was an extension of the 19th century's idea of an infinite universe. Accepting the incontrovertible evidence that the universe was expanding, he proposed that the universe was infinite in both dimension and time. According to this model, as the universe expanded new matter was continuously coming into existence by itself in just the right amount to keep the universe in a "steady state". With the sole visible aim of supporting the dogma of "matter existed in infinite time", which is the basis of the materialist philosophy, this theory was totally at variance with the "Big Bang theory", which defends that the universe had a beginning. Supporters of Hoyle's steady state theory remained adamantly opposed to the Big Bang for years. Science, however, was working against them.

THE TRIUMPH OF THE BIG-BANG
In 1948, George Gamov carried George Lemaitre's calculations several steps further and came up with a new idea concerning the Big Bang. If the universe was formed in a sudden, cataclysmic explosion, there ought to be a definite amount of radiation left over from that explosion. This radiation should be detectable and, furthermore, it should be uniform throughout the universe. 
Within two decades, observational proof of Gamov's conjecture was forthcoming. In 1965, two researchers by the name of Arno Penzias and Robert Wilson chanced upon a form of radiation hitherto unnoticed. Called "cosmic background radiation", it was unlike anything coming from anywhere else in the universe for it was extraordinarily uniform. It was neither localized nor did it have a definite source; instead, it was distributed equally everywhere. It was soon realized that this radiation was the echo of the Big Bang, still reverberating since the first moments of that great explosion. Gamov had been spot-on for the frequency of the radiation was nearly the same value that scientists had predicted it would be. Penzias and Wilson were awarded a Nobel prize for their discovery.
In 1989, George Smoot and his NASA team sent a satellite into space. Called the "Cosmic Background Emission Explorer" (COBE), it took only eight minutes for the sensitive instruments on board the satellite to detect and confirm the levels of radiation reported by Penzias and Wilson. These results conclusively demonstrated the existence of the hot, dense form remaining from the explosion out of which the universe came into being. Most scientists acknowledged that COBE had successfully captured the remnants of the Big Bang.
More evidence for the Big Bang was forthcoming. One piece had to do with the relative amounts of hydrogen and helium in the universe. Observations indicated that the mix of these two elements in the universe was in accord with theoretical calculations of what should have been remained after the Big Bang. That drove another stake into the heart of the steady state theory because if the universe had existed for eternity and never had a beginning, all of its hydrogen should have been burned into helium.
Confronted by such evidence, the Big Bang gained the near-complete approval of the scientific world. In an article in its October 1994 issue, Scientific American noted that the Big Bang model was the only one that could account for the constant expansion of the universe and for other observational results.
Defending the Steady-State theory along with Fred Hoyle, Dennis Sciama describes their predicament in the face of the evidence for the Big Bang saying that he had first taken a stand along with Hoyle but, as evidence began to pile up, he had to admit that the game was over and that the steady-state theory had to be dismissed.1
Sir Arthur Eddington's statement that "the notion of an abrupt beginning to the present order of nature was repugnant to him" was an admission of the discomfort that the Big Bang caused for materialistsThe cosmic background radiation discovered by Penzias and Wilson is regarded as incontrovertible evidence of the Big Bang by the scientific world.

WHO IS THE CREATOR ?
Who Created the Universe From Nothing?
With this triumph of the Big Bang, the thesis of an "infinite universe", which forms the basis of materialist dogma, was tossed onto the scrap-heap of history. But for materialists it also raised a couple of inconvenient questions:What existed before the Big Bang? And what force could have caused the great explosion that resulted in a universe that did not exist before?
Materialists like Arthur Eddington recognized that the answers to these questions could point to the existence of a supreme creator and that they did not like. The atheist philosopher Anthony Flew commented on this point:
Notoriously, confession is good for the soul. I will therefore begin by confessing that the Stratonician atheist has to be embarrassed by the contemporary cosmological consensus. For it seems that the cosmologists are providing a scientific proof of what St. Thomas contended could  not be proved philosophically; namely, that the universe had a beginning. So long as the universe can be comfortably thought of as being not only without end but also beginning, it remains easy to urge that its brute existence, and whatever are found to be its most fundamental features, should be accepted as the explanatory ultimates. Although I believe that it remains still correct, it certainly is neither easy nor comfortable to maintain this position in the face of the Big Bang story. 1
Many scientists who do not force themselves to be atheists accept and favor the existence of a creator having an infinite power. For instance, the American astrophysicist Hugh Ross proposes a Creator of universe, Who is above all physical dimensions as:
By definition, time is that dimension in which cause-and-effect phenomena take place. No time, no cause and effect. If time's beginning is concurrent with the beginning of the universe, as the space-time theorem says, then the cause of the universe must be some entity operating in a time dimension completely independent of and pre-existent to the time dimension of the cosmos. …It tells us that the Creator is transcendent, operating beyond the dimensional limits of the universe. It tells us that God is not the universe itself, nor is God contained within the universe.2
Objections to Creation and Why They are Flawed
It is patently obvious that the Big Bang means the creation of the universe out of nothing and this is surely evidence of willful creation. Regarding this fact, some materialist astronomers and physicists have tried to advance alternative explanations to oppose this reality. Mention has already been made of the steady state theory and it was pointed out it was clung to, by those who were uncomfortable with the notion of "creation from nothingness", despite all the evidence to the contrary in an attempt to shore up their philosophy.
There are also a number of models that have been advanced by materialists who accept the Big Bang theory but try to exorcise it of the notion of creation. One of these is the "oscillating" universe model; another is the "quantum model of universe". Let us examine these theories and see why they are invalid.
The oscillating universe model was advanced by the astronomers who disliked the idea the Big Bang was the beginning of the universe. In this model, it is claimed that the present expansion of the universe will eventually be reversed at some point and begin to contract. This contraction will cause everything to collapse into a single point that will then explode again, initiating a new round of expansion. This process, they say, is repeated infinitely in time. This model also holds that the universe has experienced this transformation an infinite number of times already and that it will continue to do so forever. In other words, the universe exists for eternity but it expands and collapses at different intervals with a huge explosion punctuating each cycle. The universe we live in is just one of those infinite universes going through the same cycle.
This is nothing but a feeble attempt to accommodate the fact of the Big Bang to notions about an infinite universe. The proposed scenario is unsupported by the results of scientific research over the last 15-20 years, which show that it is impossible for such an "oscillating" universe idea to come into being. Furthermore the laws of physics offer no reason why a contracting universe should explode again after collapsing into a single point: it ought to stay just as it is. Nor do they offer a reason why an expanding universe should ever begin to contract in the first place.3
Even if we allow that there is some mechanism by which this cycle of contraction-explosion-expansion does take place, the crucial point is that this cycle cannot go on for ever, as is claimed. Calculations for this model show that each universe will transfer an amount of entropy to its successor. In other words, the amount of useful energy available becomes less each time and every "opening" universe will open more slowly and have a larger diameter. This will cause a much smaller universe to form the next time around and so on, eventually petering out into nothing. Even if "open and close" universes can exist, they cannot endure for eternity. At some point it becomes necessary for "something" to be created from "nothing".4
Put briefly, the "oscillating" universe model is a hopeless fantasy whose physical reality is impossible.
The "quantum model of universe" is another attempt to purge the Big Bang of its creationist implications. Supporters of this model base it on the observations of quantum (subatomic) physics. In quantum physics, it is to be observed that subatomic particles appear and disappear spontaneously in a vacuum. Interpreting this observation as "matter can originate at quantum level, this is a property pertaining to matter", some physicists try to explain the origination of matter from non-existence during the creation of the universe as a "property pertaining to matter" and present it as a part of laws of nature. In this model, our universe is interpreted as a subatomic particle in a bigger one.
However this syllogism is definitely out of question and in any case cannot explain how the universe came into being. William Lane Craig, the author of The Big Bang: Theism and Atheism explains why:
A quantum mechanical vacuum spawning material particles is far from the ordinary idea of a "vacuum" (meaning nothing). Rather, a quantum vacuum is a sea of continually forming and dissolving particles, which borrow energy from the vacuum for their brief existence. This is not "nothing," and hence, material particles do not come into being out of nothing.5
So in quantum physics, matter "does not exist when it was not before". What happens is that ambient energy suddenly becomes matter and just as suddenly disappears becoming energy again. In short, there is no condition of "existence from nothingness" as is claimed.
In physics, no less than in other branches of the sciences, there are atheist scientists who do not hesitate to disguise the truth by overlooking critical points and details in their attempt to support the materialist view and achieve their ends. For them, it is much more important to defend materialism and atheism than to reveal scientific facts and realities.
In the face of the reality mentioned above, most scientists dismiss the quantum universe model. C. J. Isham explains that "this model is not accepted widely because of the inherent difficulties that it poses."6 Even some of the originators of this idea, such as Brout and Spindel, have abandoned it.7
A recent and much-publicized version of the quantum universe model was advanced by the physicist Stephen Hawking. In his book A Brief History of Time, Hawking states that the Big Bang doesn't necessarily mean existence from nothingness. Instead of "no time" before the Big Bang, Hawking proposed the concept of"imaginary time". According to Hawking, there was only a 10-43 second "imaginary" time interval before the Big Bang took place   and "real" time was formed after that. Hawking's hope was just to ignore the reality of "timelessness" before the Big Bang by means of this "imaginary" time.
Stephen Hawking also tries to advance different explanations for the Big Bang other than Creation just as other Materialist scientists do by relying upon contradictions and false concepts.
As a concept, "imaginary time" is tantamount to zero or non-existence–like the imaginary number of people in a room or the imaginary number of cars on a road. 
Stephen Hawking also tries to advance different explanations for the Big Bang other than Creation just as other Materialist scientists do by relying upon contradictions and false concepts.
Here Hawking is just playing with words. He claims that equations are right when they are related to an imaginary time but in fact this has no meaning. The mathematician Sir Herbert Dingle refers to the possibility of faking imaginary things as real in math as:
In the language of mathematics we can tell lies as well as truths, and within the scope of mathematics itself there is no possible way of telling one from the other. We can distinguish them only by experience or by reasoning outside the mathematics, applied to the possible relation between the mathematical solution and its  physical correlate.8
To put it briefly, a mathematically imaginary or theoretical solution need not have a true or a real consequence. Using a property exclusive to mathematics, Hawking produces hypotheses that are unrelated to reality. But what reason could he have for doing this? It's easy to find the answer to that question in his own words. Hawking admits that he prefers alternative universe models to the Big Bang because the latter "hints at divine creation", which such models are designed to oppose.9
What all this shows is that alternative models to the Big Bang such as steady-state, the open and close universe model, and quantum universe models in fact spring from the philosophical prejudices of materialists. Scientific discoveries have demonstrated the reality of the Big Bang and can even explain "existence from nothingness". And this is very strong evidence that the universe is created by Allah, a point that materialists utterly reject.
An example of this opposition to the Big Bang is to be found in an essay by John Maddox, the editor of Nature (a materialist magazine), that appeared in 1989. In "Down with the Big Bang", Maddox declares the Big Bang to be philosophically unacceptable because it helps theologists by providing them with strong support for their ideas. The author also predicted that the Big Bang would be disproved and that support for it would disappear within a decade.10 Maddox can only have been even more discomforted by the subsequent discoveries during the next ten years that have provided further evidence of the existence of the Big Bang.
Some materialists do act with more common sense on this subject. The British Materialist H. P. Lipson accepts the truth of creation, albeit "unpleasantly", when he says:
If living matter is not, then caused by the interplay of atoms, natural forces, and radiation, how has it come into being?…I think, however, that we must…admit that the only acceptable explanation is creation. I know that this is anathema to physicists, as indeed it is to me, but we must not reject that we do not like if the experimental evidence supports it.11
In conclusion, the truth disclosed by science is this: Matter and time have been brought into being by an independent possessor of immense power, by a Creator. Allah, the Possessor of almighty power, knowledge and intelligence, has created the universe we live in.
THE SIGNS OF THE QUR'AN

In addition to explaining the universe, the Big Bang model has another important implication. As the quotation from Anthony Flew cited above points out, science has proven an assertion hitherto supported only by religious sources.
The truth that is defended by religious sources is the reality of creation from nothingness. This has been declared in the holy books that have served as guides for mankind for thousands of years. In all holy books such as the Old Testament, New Testament, and the Qur'an, it is declared that the universe and everything in it were created from nothingness by Allah. 
In the only book revealed by Allah that has survived completely intact, the Qur'an, there are statements about the creation of the universe from nothing as well as how this came about that are parallel to 20th-century knowledge and yet were revealed fourteen centuries ago. 
First of all, the creation of this universe from nothingness is revealed in the Qur'an as follows:
He(Allah) is the Originator of the heavens and the earth…(Surat al-Anam: 101)
Another important aspect revealed in the Qur'an fourteen centuries before the modern discovery of the Big Bang and findings related to it is that when it was created, the universe occupied a very tiny volume:
Do those who are disbelievers not see that the heavens and the earth were sewn together and then We unstitched them and that We made from water every living  thing? So will they not have faith? (Surat al-Anbiya': 30) 
There is a very important choice of words in the original Arabic whose translation is given above. The word ratktranslated as "sewn to" means "mixed in each, blended" in Arabic dictionaries. It is used to refer to two different substances that make up a whole. The phrase "we unstitched" is the verb fatk in Arabic and implies that something comes into being by tearing apart or destroying the structure of ratk. The sprouting of a seed from the soil is one of the actions to which this verb is applied.
Let us take a look at the verse again with this knowledge in mind. In the verse, sky and earth are at first subject to the status of ratk. They are separated (fatk) with one coming out of the other. Intriguingly, cosmologists speak of a "cosmic egg" that consisted of all the matter in the universe prior to the Big Bang. In other words, all the heavens and earth were included in this egg in a condition of ratk. This cosmic egg exploded violently causing its matter to fatk and in the process created the structure of the whole universe.
Another truth revealed in the Qur'an is the expansion of the universe that was discovered in the late 1920s. Hubble's discovery of the red shift in the spectrum of starlight is revealed in the Qur'an as :
It is We Who have built the universe with (Our creative) power, and, verily, it is We Who are steadily expanding it. (Surat adh-Dhariyat: 47)
In short, the findings of modern science support the truth that is revealed in the Qur'an and not materialist dogma. Materialists may claim this all to be "coincidence" but the plain fact is that the universe came into being as a result of an act of creation on the part of Allah and the only true knowledge about the origin of universe is to be found in the word of allah is reavealed.
THE SOLAR SYSTEM

The solar system is one of the most wonderful examples of this beautiful harmony to be witnessed. There are nine planets with fifty-four known satellites and an unknown number of smaller bodies. The major planets counting outward from the sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. Earth is the only one on which life is known to exist. It is surely the only one on which human beings can live and survive unaided thanks to abundant land and water and to a breathable atmosphere. 
In the structure of the solar system, we encounter another beautiful example of equilibrium: the balance between a planet's centrifugal force countered by the gravitational attraction of its primary. (In astronomy, a primary is something that another body revolves about. Earth's primary is the sun; the moon's primary is Earth.) Without this balance, everything in the solar system would fly off into the chilling depths of outer space. The balance between these two forces results in paths (orbits) that the planets and other bodies follow around their primaries. If a body moved at too slow a speed, it would plunge into the primary; if it moved at too fast a speed, the primary would be unable to hold onto it, and it would fly off into space. Instead, every body moves at just the right speed to keep it in orbit. Moreover, this equilibrium has to be different for each body because the distance of planets to the sun differs. So do their masses. Therefore, they have to have different orbital speeds not to plunge into the sun or not to fly off into space.
Materialist astronomy holds that the origin and survival of the solar system can be explained by coincidence. Over the last three centuries, many of its adherents have speculated on how this marvelous order should have come to pass and they have failed to get anywhere. To a materialist, the equilibrium and order of the solar system are inexplicable mysteries.
Astronomers like Kepler and Galileo, among the first to discover this superlative equilibrium, acknowledged it as a deliberate design and a sign of divine intervention in the whole universe. Isaac Newton, recognized as one of the greatest scientific minds of all times, once wrote:
This most elegant system of suns, planets, and comets could arise from the purpose and sovereignty of an intelligent and mighty being…He rules them all, not as a soul but as a sovereign lord of all things, and because of His sovereignty He is commonly called "Lord God Almighty."1

EARTH'S FINE LOCATION

Besides this wonderful equilibrium, the place of earth in the solar system and in the universe is also another piece of evidence of a perfect act of creation on Allah's part.
The latest astronomical findings have shown the importance of the other planets' existence for Earth. Jupiter's size and position turn for example out to be critical. Astrophysical calculations show that, as the biggest planet in the system, Jupiter supplies stability to the orbits of Earth and all the other planets. Jupiter's protective role over the earth is explained in an article "How special Jupiter is" by George Wetherill:
Without a large planet positioned precisely where Jupiter is, the earth would have been struck a thousand times more frequently in the past by comets and meteors and other interplanetary debris. If it were not for Jupiter, we wouldn't be around to study the origin of the solar system.1
To put it briefly, the structure of the solar system was specially designed for mankind to live.
Let us also consider the place of solar system in the universe. Our solar system is located in one of the huge spiral arms of the Milky Way, closer to the edge than to the justify. What advantage could there be in that? In Nature's Destiny, Michael Denton explains:
What is so striking is that the cosmos appears to be not just supremely fit for our own being and for our biological adaptations, but also for our understanding... Because of the position of our solar system on the edge of the galactic rim, we can gaze farther into the night to distant galaxies and gain knowledge of the overall structure of the cosmos. Were we positioned in the justify of a galaxy, we would never look on the beauty of a spiral galaxy nor would we have any idea of the structure of our universe.2
In other words, even Earth's location in the galaxy is evidence that it was intended for mankind to live on, no less than are all the other physics laws of the universe.
It is the plain truth that the universe is created and arranged by Allah.
The reason that some people cannot understand this point is their own prejudice. But any objective mind without prejudice will easily understand that the universe is created and organized by Allah for mankind to live in, just as is revealed:
