The Universe's Deepest Question: What Came Before?

What existed before the Big Bang? Did “nothing” exist — or did time itself begin 13.8 billion years ago? In this video, we explore what modern physics says about the origin of the universe, the Big Bang theory, and whether anything existed before spacetime began. You’ll learn: • Why the Big Bang wasn’t an explosion into empty space • How Einstein’s general relativity shows spacetime can expand • What physicists mean by “nothing” in quantum field theory • The role of quantum fluctuations and virtual particles • The Planck time and the limits of modern physics • Cosmic inflation and the multiverse theory • The Big Bounce hypothesis • The zero-energy universe idea From cosmology and quantum mechanics to Stephen Hawking’s no-boundary proposal, this video examines one of the biggest mysteries in science: how the universe began — and whether “nothing” is even possible.
