What Infinity Really Implies | Leonard Susskind

Описание: Every time a physicist encounters "Infinity," they know they’ve made a mistake. Infinity isn't a physical reality—it's a red flag telling us our theories are fundamentally incomplete.

In this deep dive, we explore why the "Singularities" of General Relativity and the "Divergences" of Quantum Field Theory are actually boundaries of our knowledge. From the center of a black hole to the catastrophic prediction of vacuum energy, we break down why nature is likely discrete, finite, and "pixelated."

What we cover:

Why the Electron's infinite field is a classical error.

Renormalization: The brilliant trick to hide infinities.

Black Hole Singularities: The edge of our current equations.

Zeno’s Paradox & The Planck Length.

The Vacuum Energy Catastrophe (The worstprediction in history).

Why the "Theory of Everything" might be a theory of finite information.
