Are the seven heavens within the universe, and is there a 500-year distance between them? And what are the lamps of the lowest heaven in modern science? And are the seven earths present in every heaven, and is there life upon them?

The universe encompasses all existing creations of Allah, and the seven heavens are part of it, while the "lamps" refer to the stars. As for the seven earths, the minds of exegetes have been puzzled by them, and their true nature cannot be definitively asserted. The number seven does not negate an excess, and it could refer to regions or layers, which does not contradict the religion. Works that address scientific miracles in this area are based on speculative inferences, and scientific interpretations may change in the future. There is a possibility that there are six other earths besides ours, each with its own heaven and intelligent beings, and their inhabitants might meet us. However, the Children of Adam can only live on the Earth.
