If the universe was expanding, then it had to be smaller in the past, and there could even be a moment when the entire universe appeared as a tiny mass. A group of physicists who took these findings seriously, started theoretical research regarding the birth of the universe (that is, the space-time and all of the matter within) and its evolution. Another group of physicists still thought that the universe should have no beginning and insisted in their conception of a static universe. One of these physicists, Hoyle, made a statement during a BBC radio program in order to criticize the idea of an expanding universe and used the phrase “big bang” for the first time. Later on, the phrase, initially used in a sarcastic manner, started to be used as the name of the expanding universe model. It was an entirely new model no scientist had even imagined before. Accordingly, there had to be an electromagnetic radiation (cosmic microwave background radiation) which would emerge after the explosion—this can be compared to the smoke of a gun right after a fired shot. After Penzias and Wilson observed this electro-magnetic radiation in 1964, the doubts about the model disappeared almost completely. As technology developed over time, so many different observations and sensitive measures were made and taken in support of this theory. Since there is no other cosmological model to explain the present data, the Big Bang model has general acceptance among physicists today. We would like to relate some facts about the universe based on contemporary observations and theories before we expand our discussion.

What we know about the Universe

Galaxies are typical formations throughout the universe. The Milky Way galaxy, which hosts our solar system, is a disc-shaped one. The measurements revealed that the diameter of this “disc” is 100,000 light years and its thickness is 1000 light years (one light year is approximately ten trillion kilometers). There are approximately 100 billion other stars in the Milky Way galaxy similar to our sun. Owing to gravitational attraction, the number density of the stars near the center of the galaxy is higher—for the same reason, black holes are thought to exist in the centers of galaxies. The stars visible to the naked eye at night are the ones within the Milky Way galaxy. When further distances are observed through telescopes, other galaxies begin coming to sight as bright spots. Galaxies form galaxy clusters and the clusters form super-galaxy clusters. Even light year appears to be an unimportant unit of measurement in order to express these dazzling great distances. The most successful model we know that describes the universe is Einstein’s theory of relativity. According to this theory, space-time is a dynamic object and it can be curved. As for the force we feel as gravity, it is an outcome of the curved nature of space-time. The Big Bang model appears naturally within the general Theory of Relativity. The essential data we are going to relate here about the universe is mostly based on observations and general theory of relativity.

According to the Big Bang model, the universe was born in a very hot and dense form nearly 13.7 billion years ago. Here, we need to remember that the concepts of “time” and “space” as we know them came to being with the Big Bang. Therefore, asking what was there before the Big Bang is meaningless for this model. Similarly, the common notion of expansion brings to mind something expanding inside something else. However, it is possible to describe the universe without any notions of inside or outside expansion. That is, we do not have to assume another environment inside which the universe expands.

One of the important suggestions of the Big Bang Model is the fact that the universe was at a state of thermal equilibrium in the past. There is important data based on observation in support of this suggestion. Therefore, even though the term Big Bang brings to mind a chaotic happening, there was a very important state of equilibrium at the emergence of the universe. So many physicists have underlined the fact that this state of equilibrium is impossible to happen on its own. Our universe was born out of a very hot and dense state of equilibrium and it began to cool down as it expanded. The heat in the early periods was so high that matter was found in a plasma state formed by the smallest constituents of matter. As the heat decreased, the plasma also changed structure and different cosmic phases took place. For instance, when the heat dropped down to 1010 C atomic nuclei began to form out of neutrons and protons. When it dropped to 3000 C, atoms were formed. There are many observations in support of these different phases. For example, the electro-magnetic background radiation observed by Penzias and Wilson in 1964 is formed out of photons (i.e. light) released after the phase in which the first atoms are formed. The Big Bang model has so many more important details and the calculations made according to this model have been in conformity with observations. Together with that, it should be noted that as the known physics get closer to the moment of the bang (zero time), it loses validity and new theories are needed.

The expansion of the universe in the Qur’an

The Qur’an openly refers to the expansion of the universe. The 47th verse of the 51 chapter (Dhariyat) is translated as follows:

And the heaven, We have constructed it mightily; and it is surely We Who have vast power, and keep expanding it. (51:47)

The original Arabic phrase used, which refers to expansion, is “musiun.” The interesting point is that the sentence is a noun clause which denotes in Arabic grammar a quality of being steady and continuous. Therefore, the meaning can be understood as being “we are expanding it continuously.” According to the Big Bang model, the universe has constantly been expanding ever since it was born. Expressing this fact by saying “We are expanding it,” the Qur’an also guides us to acknowledge that the expanding does not happen in itself but is realized by Divine power.

Other verses related to the Big Bang

The 30th verse of the chapter Anbiya is translated as follows:

Do those who disbelieve ever consider that the heavens and the earth were at first one piece, and then We parted them as separate entities; and that We have made every living thing from water? Will they still not come to believe? (Anbiya 21:30)

According to some scholars of Qur’anic exegesis, the phrase ratq (joined together, one piece) and fataqnahuma (We parted them) can be alluding to the moment of the Big Bang. As we have tried to summarize above, the entire universe was a single and very small mass and then started to expand and grow. As the universe expanded, the matter it contained began to expand and occupy a larger volume. As the universe expanded, its contents also began to separate from one another. So the phrases mentioned might be alluding to this chain of events. Together with that, some scholars thought that this verse alludes to the formation of the solar system, earth, and its atmosphere. The reason is that the verse continues with referring to the creation of living things. Accordingly, ratq might be referring to the phase when the solar system was a single mass and fataqnahuma might be referring to the planets and the earth breaking away from the sun and the formation of the atmosphere. It should be noted that systems forming within galaxies are also considered in the Big Bang model, which is used for referring to all of the phases from the time of zero to ours. Therefore, both possible explanations can be related to this model.

Another phrase which can be related to the Big Bang is the “Originator (Fatir) of the heavens and the earth” used in many different verses (e.g. Yusuf 12:101). Similarly, there is another verse expressing this reality with a verb from the same root (fatarahunna): …your Lord is the Lord of the heavens and the earth, Who has originated them each (Anbiya 21:56). Normally the phrase “fatara” is translated as “created.” In his study of Qur’anic exegesis (not available in English), Hamdi Yazir (1877-1942) points to the fact that the root “fatara” means to “split” or “split lengthwise,” and to originate something for the first time without a prior model. When these meanings of “fatara” are taken into consideration, “Originator (Fatir) of the heavens and the earth” can be an allusion to the Big Bang. Let us remember the fact that the Big Bang particularly refers to the very moment of the first creation. Therefore, the meaning “to originate something for the first time without a prior model” might be referring to this quality of the Big Bang. In addition, the word “split” expresses the moment of this great explosion better than the word “bang”; and so the beginning of space-time can be compared to splitting of a seed and its emergence.

One of the alternative meanings of “fatara” mentioned by Yazir, “split lengthwise” is very interesting. One of the important misconceptions about the Big Bang is to imagine that the universe was born in a certain spot and began expanding within another space. The Big Bang did not take place at a single spot. According to our theoretical understanding today, the entire space came into being altogether in a single moment. In other words, the Big Bang took place everywhere. When we consider the meaning “split lengthwise,” it might be an allusion to the fact that the Big Bang did not take place at a single point.

Conclusion

Considering the points we have tried to summarize above, the Qur’anic verses related to the creation of the universe can be defined as evidently miraculous. Surely, it is possible to expound on the subject from different aspects. For example we can think about a relation between the phrase “the seven heavens” used in many different verses in the Qur’an and the different phases after the Big Bang (although it is not possible pinpoint the exact number of these phases, figures like seven or seventy are metaphorically used in Arabic for referring to something in relevant multitude). Or they might be referring to some extra dimensions suggested by certain theories (The String Theory, one of the most-studied theories in recent years suggests the existence of seven extra dimensions).

Finally, we would like to underline that this article is an elementary attempt. What needs to be done more seriously is to form a board of scholars, particularly from the fields of cosmology and Qur’anic exegesis, and evaluate systematically all the verses related to the subject, and then try to analyze and understand them without any biased opinions. Such a study can provide deeper insight into the Qur’anic message.

In this work we study a verse from the Qur’an, the 47th verse of the Sura al-Dhariyat (The Winds that Scatter), under the light of new discoveries in the field of astrophysics. We note that recent evidence about the accelerating expansion of the universe is also strongly consistent with this verse, although this has shocked the scientific community. In the last part of the article, we discuss possible relations of “metaphysical dimensions” and the concept of “the seven layers” with the word “sama” (translated in to English as “heaven”) as mentioned in the verse.

The existence of the universe is perhaps one of the greatest mysteries in science and philosophy. No convincing argument has been ever put forward that has enabled us to understand this amazing event, not since the beginning of modern science. Religions like Islam, Christianity, and Judaism, on the other hand, explain that the Creator built our robust universe directly out of physical nothingness, independent of any cause. Therefore, the initial creation of such universe would be impossible to explain physically (M. F. Gulen, from his conference on “Evolution and reality”).

In his translation of the relevant verse, S. Yildirim has noted that God keeps the universe expanding and He will continue to do so. Yildirim attributes two meanings to the word musiun in the verse; the first is the owner of great power, strength and wealth; the second is one who expands. Thus, it should not be a surprise to learn that this verse is indeed describing a continually-expanding universe. This might further lead Muslims to think that the Creator has not left the universe unattended after the Big Bang, but rather it is He who has kept creating and expanding it.

In the 1920’s a discovery was made that completely changed our perception of space. It was discovered that distant stars depart from the solar system and leave us even more and more alone in dark space. Then, Fr. Georges-Henri Lemaître, a Belgian astrophysicist, mathematician, and Catholic priest, proposed the idea of the expanding universe. Despite its finite size, it was believed that the universe was expanding.

We can explain this fact simply by an analogy. Think of a toy balloon with spots on it. Mark one of those spots and inflate the balloon. As we inflate it, we observe that all other spots on the surface of the balloon move away from the marked one. So, if we replace the balloon with our universe, the spots will be the stars and planets. If the universe is expanding indeed, then we expect them to be moving away from each other. In other words, the distances between heavenly bodies must be increasing.

Unfortunately, we don’t have a gigantic ruler to measure such immense distances. However, there are other means, such as measuring wave frequencies. Consider the following analogy: Someone throws one ball every second toward a target. Assume that balls travel with constant velocity. If the thrower is stationary, the target will receive one ball every second. However, if the thrower is moving towards the target, it will receive balls more frequently because the balls will be less spaced out. The converse is true if the thrower is moving away from the target. So it is actually the wavelength which is affected; as a consequence, the perceived frequency is also affected. That is, the distances between the waves emitted by objects moving away from us (wavelength) must be increasing, so the frequency decreasing. Likewise, think of an ambulance siren coming towards you and going away from you. It is a good example showing that while an acoustic source that is approaching us emits a higher frequency, the same source radiates lower frequency when going away from us. In physics this is known as the Doppler effect.

Red shift

This phenomenon does not only occur with sound waves, but also with electromagnetic waves. When we think of the spectrum of light, violet at one end has the shortest wavelength and red at the other end has the longest wavelength of visible light. So, any wave of light shifting toward red means the source is moving away from us. It has been determined that the frequency of light emitted by the elements within distant stars shift to a lower frequency, which is called a red shift.

It is this shift that makes astrophysicists think that the universe is expanding. One mustn’t be confused by red shift. This terminology is just used to explain in what direction the frequency is actually shifting on the spectrum. Those signals captured from distant stars have a much smaller frequency (much higher wavelength) than that of red light and they are indeed in the microwave regime and shifting to even much smaller frequency radio waves.

In 2002, an article presenting new evidence of the accelerating expansion of the universe was published by the Royal Astronomical Society. It was not so long ago, only five years, that general opinion concurred with a decelerating expansion. However, the first evidence found by two astronomers in that year led us into a universe that expands in an accelerating fashion, contrary to previous views. This result was absolutely unexpected, because many scientists believed that expansion would slow down due to gravity. Another interesting fact is that if space were to cease expanding, this would be in contradiction to the above verse. God, however, by never allowing this to happen, shows how futile the actions of those who deny His verses are and how extensive His power is, as well as how purposefully He creates.

Dark energy

The groups who worked in the above study figured out, from the brightness of supernovas in distant galaxies, that the universe must expand more and more in the future due to a peculiar dark energy within it. The concept of dark energy was first postulated by Einstein, who named it the “cosmological constant.” However, since this did not fit in well with his theory of general relativity, he withdrew it and said that it was a scientific blunder. Since then, dark energy has had a rather controversial history.

A team of 27 astronomers, directed by Professor Efstathiou of Cambridge University, proposed strong evidence supporting the existence of dark matter, based on completely novel techniques. Their results, which were consistent with previous supernovas, showed that the universe is indeed full of dark matter. Professor Efstathiou thinks that the explanation of dark energy might include additional dimensions like creation (Big Bang) as well. Fr. Lemaître also proposed the expanding universe theory at an opportune time since Edwin Hubble would soon release his red shift observations that strongly supported an expanding universe and, consequently, the Big Bang theory. Here, the Big Bang is seen as the beginning of a continuous expansion.

The verse seems to tell us miraculously that the expansion of the universe will not cease, despite our limited knowledge of the physical reason for its acceleration.

The Hubble Telescope

Another article, published in Nature, presents us the first and deepest picture of space taken by the Hubble Space Telescope. This caused the astronomers to compete in solving the mysteries of the arts of God. The picture, also known as the Hubble Ultra Deep Field, was broadcasted and published in various programs and journals. It has not only shown us the farthest stars of the universe, but the youngest as well. It was very difficult to detect such weak light with the former technology. This picture reveals the embryonic universe, with an age of only 500 million years old. Estimated age of the universe is 13-14 billion years. Three physicists from American Natural History Museum in New York started a competition to publish an article on the Ultra Deep Field picture after the data was disclosed. They hope to answer many questions about the past and future universe. A group at the Stony Brook University, New York, directed by Kenneth Lanzetta, analysed the embryonic samples in the picture to try to discover when various galaxies had been born and how they had evolved. Two other groups are studying the motions of stars and galaxies, as the picture is a result of data collected over a month.

Having looked at the expansion of universe under the light of recent discoveries, now we turn our attention to two other arguments that could be relevant to expansion. Namely, ether (a substance which it is believed fills up the vast universe and which is the ultimate building block of the space), and the seven-layer-universe.

Despite the Michelson-Morley experiment, which argued against theory of luminiferous ether, the propagation of electric, light, or heat in space shows the existence of a substance through which they flow. The Michelson-Morley experiment is nothing more than just a test of the non-existence of certain qualities of ether. For example, in order to show the existence of photons, of which light is made up, we cannot go beyond showing the features of photons. In other words, depending on how we have defined its qualities, we can observe different aspects in the photon, ether, or anything else. In fact, even today, we don’t really know what a photon really is, although we observe its affects every day. In short, it is not possible to show the non-existence of phenomena that cannot be absolutely defined. Instead, we can only test the existence of the properties that we have defined and attributed to them, and thus we better understand their nature of existence in the context of those pre-defined qualities. Hence, the existence of ether is still controversial and needs more thorough research.

Seven layers

Regarding the seven-layer-universe, on the other hand, how is it possible for ether to manifest itself in seven heavens? It may be that these seven layers are not all posed above our heads, but rather that they may be found one with another. The universe is composed of many systems and networks that are the building blocks of their counterparts on larger scales. Each system is governed by laws, which differ slightly from one another. Inside the atom there exists a proton with its unique organization and in a proton we find quarks. For example, communication between protons and electrons is mediated by the electromagnetic force, while the quarks inside the protons communicate via the strong force. These interleaved circles show us that the universe is indeed composed of numerous layers.

We may use these layers for the metaphysical world as well. The human being is not only composed of matter, but also has a mind, a soul, and intelligence. Although these components are accepted as existing by all, their exact nature has not yet been explained by positive sciences.

It seems that the universe is composed of at least two different worlds: The material world (physical) and the immaterial (metaphysical) world. Are these two worlds completely separate, or do they have some features in common? In fact, the existence of humanity might prove to be this common set. But, it may also be true for the universe itself. Nursi states that the distant galaxies, stars and planets are not empty, but home to many spirits and angels who have their own consciences. Thus, one can say that despite the boundaries which separate these two worlds, such as different numbers of temporal and spatial dimensions, they constitute a whole, the Universe. The interaction between them will never fail as long as the universe exists.

The existence of two separate worlds is not that difficult to believe, but there is more:

It is He Who (prepared the earth for your life before He gave you life, and) created all that is in the world for you (in order to create you – the human species – and make the earth suitable for your life); then He directed (His Knowledge, Will, Power, and Favor) to the heaven, and formed it into seven heavens. He has full knowledge of everything. (Baqara 2:29)

The Qur’an calls the heaven where the sun, moon and stars are the lowest heaven or the heaven of the world (Mulk 67:5). The other six heavens may be the heavens of the worlds of the Hereafter.1 We are not sure whether this seven-layer heavens can only be attributed to the physical universe. It might be able to apply to the universe as a whole, with its all seen and unseen layers as well. Even the worlds of angels and spirits may be expanding in accordance with the laws therein, to show how the power and the wealth of God are comprehended in those worlds as well. Although our Earth is finite, the expansion may not be restricted to our finite world, but it may continue in infinite worlds as well.

It is possible that the space being filled with ether has an important role in paving the orbits of planets or stars, as well as other heavenly bodies. We believe that future studies on dark matter, ether, and string theory will help us to better understand the expansion process of the universe.
