The ‘cyclic universe’ theory suggests the universe might recycle itself, avoiding a singular beginning. Unlike the Big Bang model, which faces challenges in explaining uniformity, inflation, and singularity, the ekpyrotic model proposes that the universe repeatedly contracts and expands. A brane-based version, linked to M-theory, suggests that brane collisions cause Big Bangs. Future discoveries might test these competing theories.
