He Who created the seven heavens in layers. You will not find any discrepancy in the creation of the All-Merciful. Look again-do you see any gaps? Then look again and again. Your sight will return to you dazzled and exhausted! (Surat Al-Mulk, 3-4)

In the universe, the concept of speed assumes giant dimensions when compared to earthly measurements. Stars, planets, galaxies and conglomerations of galaxies-whose numerical properties can only be conceived by mathematicians-weigh billions or trillions of tons, and move through space at extraordinary speeds.
For example, the Earth rotates at 1,670 kmph (1,038 mph). If we consider that the fastest-moving bullet today possesses an average speed of 1,800 kmph, we can see how fast the Earth is moving, despite its enormous size and mass.
The speed of the Earth as it orbits the Sun is some 60 times faster than a bullet: 108,000 kmph. If we were able to construct a vehicle capable of moving at that speed, it would be able to circumnavigate the Earth in 22 minutes. These figures apply only to the Earth.

There is no doubt that there is a very high risk of collisions in such a complicated and fast-moving system. Yet nothing of the sort actually happens and we continue with our lives in complete safety. That is because everything in the universe functions according to the flawless equilibrium set out by Allah. It is for this reason that, as stated in the verse, there is no "discrepancy" in the system.
