Summary
What existed before the Big Bang? This episode explores cutting-edge theories that attempt to answer one of physics’ deepest questions. From quantum “bounce” models and cyclic universes to eternal inflation and the idea that time itself may have no true beginning, scientists are searching for new frameworks beyond general relativity to describe the universe’s origin. While still unproven, these ideas could redefine our understanding of time, space, and cosmic history. This episode includes AI-generated content.
