7 Theories About What Existed Before the Big Bang

What existed before the Big Bang? Was it nothing… or something far more disturbing? In this video, we explore seven of the most profound and unsettling theories in modern cosmology. From Conformal Cyclic Cosmology, where the death of a previous universe becomes our beginning, to the idea that our entire cosmos emerged from a quantum fluctuation out of “nothing.” We dive into Loop Quantum Cosmology and the Big Bounce, brane collisions in higher dimensions, eternal inflation creating infinite bubble universes, a CPT-symmetric mirror anti-universe flowing backward in time, and finally the terrifying scale of the String Landscape and the multiverse. These theories challenge everything we think we know about reality, time, and existence itself. If even one of them is correct, the Big Bang wasn’t the beginning — it was just one event in something far larger, stranger, and possibly eternal. The universe may not have started. It may have restarted. Subscribe for more deep space explorations. #BigBang #Cosmology #Multiverse
