What Existed Before the Big Bang? | Documentary for Sleep

What existed before the Big Bang? Was there truly a "before," or does that question even make sense? Join us on a journey through humanity's most profound cosmological mystery. In this comprehensive documentary, we explore the cutting-edge theories that attempt to answer what came before our universe's explosive beginning 13.8 billion years ago. From quantum cosmology to multiverse theory, from bouncing universes to hidden dimensions, we examine the scientific frontiers where physics meets philosophy.
