What Holds up the Sky?

Today scientists speak of gravitational forces that hold the heavenly bodies apart from each other and prevent them from colliding with each other. How was this to be conveyed to the first readers of the Quran? God tells us in the Quran that He is the One Who raised the sky (Quran 55:7) and that he holds it back from falling on the earth (Quran 22:65). But how exactly does God do this?

If the author of the Quran was a human being, it would have been very easy for the author to copy the answer to this question from the Bible. But today no one will believe that answer.

In the New American Bible, a picture is drawn to show how the authors of the Bible imagined the world to look like. In that picture, the sky "resembles an overturned bowl and is supported by columns" (The New American Bible, St. Joseph's Medium Size Edition, pp. 4-5). The earth in that picture is flat, and is also supported by pillars. After describing the picture at length, the editors of that Bible conclude by calling that idea of the world a "prescientific concept of the universe."

At the time when the Quran was being revealed, anyone could have easily believed this description which was already found in the Bible. It is only in modern times that people would know better. How did the author of the Quran avoid this mistake?

God says in the Quran that He created the heavens "without any pillars that you can see" (Quran 31:10). Again, the Quran says: "God is the One Who raised the heavens without any pillars that you can see" (Quran 13:2). Dr. Maurice Bucaille comments: "These two verses refute the belief that the vault of the heavens was held up by pillars, the only things preventing the former from crushing the earth" (The Bible, the Quran and Science, p. 154).

To be able to avoid that prescientific error, the author of the Quran must have been either a modern scientist, or God Himself.
