Physics: Flat Universe
The concept of a “flat universe” is a pivotal idea in modern cosmology, emerging from the interplay between Einstein’s theory of general relativity and the Friedmann–Lemaître–Robertson–Walker (FLRW) metric. General relativity, proposed by Albert Einstein in 1915, revolutionized our understanding of gravity by describing it as the curvature of spacetime caused by mass and energy. The…
