28. From the wording of the text, it appears that at first the whole universe was a single mass of matter; then it was split into different parts and the earth and the other heavenly bodies were formed. For more details, please see (Surah HaMim, E.Ns 13-15).

35. The use of the words kullun (all) and yasbahun (float) in the plural (for more than two) indicates that not only the sun and the moon but all the heavenly bodies are floating in their own separate orbits and none of them is fixed or stationary. These (verses 30-33) are capable of being interpreted in the modern scientific terms in accordance with the present day conceptions of Physics, Biology and Astronomy.
Here it should also be noted that( verses 19-23) refute shirk while verses 30-33 present positive proofs of Tauhid. They imply that the creation and regular functioning of the universe clearly show that it is the work of One All- Powerful Creator, and no sensible person can say that it has been created as a mere pastime for the sake of fun. When the fact is this and you see proofs of the doctrine of Tauhid all around you, in the earth and heavens, why do you reject the message of the Prophet (peace be upon him) and demand other signs from him.
