It is Allah Who raised the skies (heavenly bodies) without any support which you see, then set the balance on the throne (of the universe), and He compelled the sun and the moon (to follow His laws), each one moves fast till an appointed time. He governs the affair. The signs are explained in detail by Him that you may be certain of meeting your Fosterer.
We do not see any hooks or pillars on which heavenly bodies weighing in millions of tones are supported. They freely float in space. A rotational motion keeps the individual members of the planetary system in equilibrium against the gravitational pull of the sun. In the case of a star, the explosions due to nuclear reactions are counter acted by the implosive force of its gravity. On the universal scale, there is a balance between the run away expansion of various groups of galaxies and a violent collapse due to the increasing force of mutual gravitation. This is how the heavenly bodies, freely suspended in space, follow the orders of Allah (SWT) which we call laws of nature.
