Richard Feynman on Entropy | Does the Past Still Exist?

Описание: Richard Feynman on Entropy | Does the Past Still Exist?

n this mind-bending talk, Richard Feynman explores entropy, time’s arrow, and one of the deepest questions in physics: does the past still exist, or is it truly gone forever? With his signature clarity and curiosity, Feynman breaks down why the laws of physics mostly work the same forward and backward in time—yet our everyday experience only moves one way. From broken cups to cosmic evolution, this video connects thermodynamics, memory, and reality itself, revealing why entropy gives time its direction and why the past feels unreachable, even if the equations don’t forbid it.

WHY WE WATCH THIS VIDEO
We watch this video to understand why time only seems to move forward, how entropy shapes reality, and why memory, order, and decay are deeply connected. Feynman’s explanation helps us question our assumptions about past, present, and future—and shows how simple physical laws lead to profound philosophical consequences about existence itself.
