What if the Big Bang wasn’t the true beginning of everything? In this video, we explore the biggest mysteries at the edge of modern cosmology: ancient James Webb galaxies that formed too fast, colossal structures like the Big Ring and Giant Arc, new DESI data suggesting dark energy may be changing over time, and the terrifying problem of the singularity. From the Cosmic Microwave Background and dark matter to eternal inflation, the holographic principle, the Big Bounce, and Roger Penrose’s Conformal Cyclic Cosmology, this is a journey into what may have existed before the Big Bang - and why the beginning of time might be stranger than we ever imagined.
