10 Theories About What Existed Before the Big Bang What existed before the Big Bang? Was our universe born from nothing, created inside a black hole, reborn from a dead cosmos, or just one tiny bubble in an endless multiverse? In this Astro Buddy episode, we explore 10 terrifying theories about what may have existed before the beginning of time — from Conformal Cyclic Cosmology and quantum fluctuations to the Big Bounce, eternal inflation, mirror universes, brane collisions, and the string landscape multiverse. The deeper we go, the stranger the question becomes: maybe the Big Bang was not the beginning at all. #AstroBuddy #BigBang #UniverseMysteries
