How Can Light Be Older Than the Universe? | Leonard Susskind

Описание: How can light be older than the universe itself? It sounds impossible — yet modern cosmology suggests something even stranger.

In this fascinating lecture, Leonard Susskind explores one of the deepest paradoxes in physics: the origin of the oldest light in the cosmos, often linked to the Big Bang and the discovery of the Cosmic Microwave Background.

Is this ancient radiation truly the oldest thing we can observe? What does it reveal about time, space, and the birth of the universe? And could our understanding of “beginning” itself be flawed?

Prepare for a mind-expanding journey into cosmology, quantum theory, and the limits of human intuition.
