Why the Big Bang Never Happened | Leonard Susskind

Описание: The Big Bang is often described as the moment when everything began — a cosmic explosion that created space, time, and matter. It is one of the most familiar ideas in modern science. But in fundamental physics, this story is deeply misleading.

In this video, we explore why the Big Bang may never have “happened” in the way most people imagine.

Physics does not deny the evidence of an expanding universe. What it challenges is the idea that the Big Bang was a physical event occurring at a specific moment in time. In many modern frameworks, the Big Bang is not an explosion, not a beginning, and not an event at all — but a boundary of our description.

Drawing on ideas associated with Leonard Susskind, this video explains how space and time themselves may be emergent, not fundamental. If time is not fundamental, then asking what happened “at the beginning” may be the wrong question entirely. The Big Bang becomes a limit where our equations stop working, not a moment when reality came into existence.

We explore how concepts from quantum gravity, black hole physics, and information theory suggest that the universe may not have a single origin story. Instead, the Big Bang may represent a transition, a boundary condition, or even a breakdown of classical intuition.

This perspective does not reject cosmology — it refines it. The universe still expands, galaxies still move apart, and the cosmic microwave background still exists. But the familiar narrative of a cosmic birth may be more story than structure.

This documentary-style video avoids equations and focuses on intuition. It is designed for viewers who want to understand what modern physics actually says — and why some of our most popular explanations may be fundamentally wrong.
