Why the Universe Has No Beginning | Leonard Susskind

We are all taught that the universe began 13.8 billion years ago at the Big Bang. But what if that is completely wrong? The mathematical "singularity" isn't a physical reality—it's just where our current physics breaks down. In this video, we dive into the deepest frontiers of modern cosmology. We explore why the concept of a "cosmic beginning" is fundamentally flawed, how quantum mechanics eliminates the Big Bang singularity, and the mind-bending theories that replace it. From the Big Bounce and emergent time to eternal inflation and the Wheeler-DeWitt equation, discover why reality might be entirely timeless. ⏱️ Chapters: 0:00 - The Standard Big Bang Story (And Why It’s Wrong) 1:45 - The Death of the Singularity 3:30 - Quantum Bounces & Stephen Hawking's No-Boundary Proposal 6:15 - Eternal Inflation & Pocket Universes 8:50 - Emergent Time: Is Time an Illusion? 11:20 - The Philosophy of a Necessary Universe If this video changed the way you view reality, hit the Like button and Subscribe for more deep dives into physics, cosmology, and the nature of existence!
