CREATION IN SIX DAYS Your Lord is Allah, Who created the heavens and the earth in six days and then settled Himself firmly on the Throne... (Qur'an, 7:54) One example of the harmony between the Qur'an and modern science is the subject of the age of the universe. Cosmologists estimate the age of the universe as 16-17 billion years. The Qur'an states that the entire universe was created in six days. These two time frames, which may seem contradictory, are actually surprisingly compatible. In fact, both these figures concerning the age of the universe are correct. In other words, the universe was created in six days, as revealed in the Qur'an, and this period corresponds to 16-17 billion years in the way that we experience time. In 1915 Einstein proposed that time was relative, that the passage of time altered according to space, the speed of the person travelling and the force of gravity at that moment. Bearing in mind these differences in the passage of time, the period of time in which the universe was created as revealed in seven different verses of the Qur'an is actually highly compatible with scientists' estimations. The six-day period revealed in the Qur'an can be thought of as six periods. Because, taking into account the relativity of time, a "day" refers only to a 24-hour period experienced on Earth under current conditions. Elsewhere in the universe, however, at another time and under other conditions, a "day" could refer to a much longer period of time. Indeed, the word "ayyamin" in the period of six days (sittati ayyamin) in these verses (Qur'an 32:4, 10:3, 11:7, 25:59, 57:4, 50:38, and 7:54) means not only "days," but also "age, period, moment, term." In the first period of the universe, the passage of time took place much faster than that with which we are familiar today. The reason for this is that, at the moment of the Big Bang, our universe was compressed into a very small point. The expansion of the universe and increase in its volume ever since the moment of that explosion has extended the borders of the universe to millions of light years. Indeed, the stretching of space ever since that moment has had very important ramifications for universal time. The energy at the moment of the Big Bang slowed down the flow of time 1012 (one million million) times. When the universe was created the speed of universal time was higher up to a million million times, as time is experienced today. In other words, a million million minutes on Earth is the equivalent of just one minute in universal time. When a six-day period of time is calculated according to the relativity of time, it equates to six million million (six trillion) days. That is because universal time flows a million million times faster than time on Earth. Calculated in terms of years, 6 trillion days equates to approximately 16.427 billion years. This is within the estimated range for the age of the universe. 6,000,000,000,000 days/365.25 = 16.427104723 billion years Allah, there is no god but Him, the Living, the Self-Sustaining. He is not subject to drowsiness or sleep. Everything in the heavens and the earth belongs to Him. Who can intercede with Him except by His permission? He knows what is before them and what is behind them but they cannot grasp any of His knowledge save what He wills. His Footstool encompasses the heavens and the earth and their preservation does not tire Him. He is the Most High, the Magnificent.

(Qur’an, 2:255) On the other hand, each of the six days of creation equates to very different periods, as we perceive time. The reason for this is that the speed of the passage of time declines in proportion to the expansion of the universe. Ever since the Big Bang, as the size of the universe doubled, so the passage of time halved. As the universe grew, the speed at which the universe doubled increasingly slowed down. This rate of expansion is a scientific fact acknowledged the world over and described in the text book The Fundamentals of Physical Cosmology. When we calculate every day of creation in terms of Earth time, the following situation emerges: Looked at from the moment when time began, the first day of creation (first phase) lasted 24 hours. This period, however, is the equivalent of 8 billion years in Earth terms.

The second day of creation (second phase) lasted 24 hours. This, however, lasted half as long, in our terms, as the preceding day, in other words 4 billion years.

The third day (third phase) lasted half as long as the second day, in other words 2 billion years.

The fourth day (fourth phase) lasted 1 billion years.

The fifth day (fifth phase) lasted 500 million years.

And the sixth day (sixth phase) lasted 250 million years.

Conclusion: When the six days of creation, in other words the six phases, are added together in Earth terms, the resulting figure is 15 billion 750 million years. This figure displays an enormous parallel with modern-day estimations. This conclusion is one of the facts revealed by 21st century science. Science has once again confirmed a fact revealed in the Qur'an 1,400 years ago. This harmony between the Qur'an and science is one of the miraculous proofs that the Qur'an is the revelation of Allah, the Creator, the Omniscient.
