What is the meaning of the verse, "Allah is He Who raised the heavens without any pillars that you can see," and what is meant by "heaven," and is it a physical entity that is raised upon pillars?

The noble verse in Surat Ar-Ra'd (2) and Surat Luqman (10) describes the raising of the heavens without visible pillars, which is evidence of Allah Almighty's power and greatness. Linguistically, "heaven" (السماء) refers to everything that is high and elevated, including all celestial bodies above us. Some scholars have suggested that the invisible "pillars" might be gravity, which holds the universe together and prevents celestial bodies from colliding. This is considered a scientific miracle in the Holy Quran, which alluded to this phenomenon centuries before its discovery.
