While the Big Bang Theory is widely accepted, there are alternative theories that attempt to explain the origin of the universe:
Steady State Theory: Proposes that the universe has no beginning or end and that new matter is continuously created as the universe expands. Cyclic Model: Suggests that the universe undergoes an infinite series of expansions and contractions (Big Bangs and Big Crunches). Multiverse Theory: Posits that our universe is just one of many universes that exist simultaneously.
