He (Allah) 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! (Qur'an, 67:3-4)
The perfect balance in which the various parts of the universe exist is mind-boggling. Here is one example:
The billions of stars and galaxies in the universe move in perfect equilibrium in the paths set out for them. Stars, planets and satellites rotate not only around their own axes but also together with the systems of which they are an integral part. Sometimes, galaxies containing 200-300 billion stars move across each others' paths. Yet amazingly, no collisions take place that might damage the great order in the universe.
The Earth rotates at 1,670 km/h. The speed of the Earth as it orbits the Sun is 108,000 km/h. The Solar System's speed of orbit around the centre of the galaxy is 720,000 km/h. The Milky Way, with its 200 billion or so stars, moves at 950,000 km/h. There is a very high risk of collisions in such a complicated and fast-moving system. Yet nothing of the sort happens. That is because everything in the universe functions according to the flawless equilibrium set out by Allah.
Qur’aan stated hundreds of years ago what we are only getting to know now: that there’s no discrepancy in the system.
