Expansion of the Universe
At a time when the science of Astronomy was still primitive, the expansion of the universe was described in Quran:
“And it is We who have built the Universe with [Our creative] power and keep expanding it.” (Quran 51:47)
The fact that the universe is expanding was discovered in the last century. The physicist Stephen Hawking in his book ‘A Brief History of Time’ writes, “The discovery that the universe is expanding was one of the great intellectual revolutions of the 20th century.”.
The Quran mentioned the expansion of the universe even before the invention of the telescope!
