Why the Universe Is Not a Thing | Leonard Susskind

Описание: You think the universe is the biggest object in existence—a giant container holding all the stars, galaxies, and planets. But modern physics and cosmology suggest this is profoundly wrong. The universe is NOT a "thing."

In this video, we break down the ultimate illusion of reality. We explore why treating the universe as a physical object fails when you apply General Relativity, Quantum Mechanics, and the Wheeler-DeWitt equation. From the shrinking edge of our observable cosmic horizon to the mind-bending realities of eternal inflation and the multiverse, we discover why the universe behaves less like a physical container and more like a mathematical framework.
