The universe came into existence billions of years ago. This event is called the "The big bang,  clearly mentioned in the
Quran in the above verses. God the Revealer of the Quran knew 1400 years ago that the discovery of "The Big Bang" and that of "The
aquatic origin of life" will be made by the non-Muslims, ("those who disbelieve"). When the universe began all matter and space
(heavens) was at one point (one piece).  Then everything was separated in what the physicists describe as "The big bang."
The evidence that the universe began in the "The big bang" is so overwhelming that it is now considered a fact and not just a theory.

                                            THE RECEDING GALAXIES: THE EXPANSION OF THE UNIVERSE

             The galaxies other than our "Milky Way" are moving away from us at tremendous speeds. This can be ascertained, by
analyzing the light given off by the galaxies, by an instrument called the spectroscope. The more distant a galaxy is the greater is its
speed of recession. This motion of the galaxies is due to the expansion of the universe. The universe began about fifteen to twenty
billion years ago with a tremendous explosion called "The big bang" and has been expanding ever since. The universe is not just a
sphere of galaxies rushing away from each other into unending emptiness of space. It can be compared to a balloon with many dots
on it, each representing a galaxy. However, the surface of this balloon, which is two dimensional, represents all three dimensions of
our space, and is expanding into a higher dimension, that is beyond our imagination. The expansion of the universe is clearly
mentioned in the following Quranic verses:
Qur'an Chapter 51 Verse 47
The heavens, We have built with power, And We are expanding it.
                                                                                                             THE ACCELERATING EXPANSION

          "THE PHYSICS OF THE DAY OF JUDGMENT" is based on the concept that the expansion of the universe (space) is the
cause of the “phenomenon of time.”
If this is true then the universe will “appear” to be expanding faster as we try to measure
the expansion rate of the universe with our present slowing time. This anomaly of faster expansion was discovered by two groups of
astronomers in 1998.  Unaware that our time could be slowing, the physicists are now trying to explain this surprising finding by
some undiscovered property of space or repulsive force that may make the universe expand faster. Another group of scientists from
the University of the Basque Country in Bilbao, and Spain’s University of Salamanca believe that slowing of our time is causing us to
mistakenly interpret these measurements as accelerated expansion of the universe.

         It should be noted that we cannot measure or notice slowing of time locally, however if our time is slowing then if we look into
the distant space where light is coming to us from billions of years ago we will see evidence for a faster time in the past. This is what
astronomers are observing when they talk of accelerating expansion of space. A faster expansion in distant past means slowing of
our time and slowing of expansion of space locally.

        The slowing of expansion will eventually cause time to stop and then time will reverse when the universe starts contracting.
The Quran clearly supports this scenario in the following verses in which contraction of the universe is compared to the rolling up of
a scroll and also suggests that the process of creation will be repeated.
Qur'an Chapter 21 Verse 30
Have not "those who disbelieve" known that heavens and earth were of one piece,
We parted them and, We made every living thing of water, will they not then believe?
Qur'an Chapter 21 Verse 104
"The day" when, We shall roll up the heavens as a recorder rolls up a written scroll.
As, We began the first creation We shall repeat it.
