Something Terrifying Existed Before the Big Bang Brian Cox

What existed before the Big Bang? This question has long challenged scientists and philosophers alike. Now, emerging theories in modern physics are offering new possibilities—ideas that push the limits of our understanding of time, space, and reality itself.

In this program, Professor Brian Cox explores what current science suggests may have existed before the birth of our universe. From quantum fields and cyclic universes to scenarios where time itself behaves in unfamiliar ways, these ideas challenge conventional thinking and raise profound implications about the nature of existence. Some of these concepts are so counterintuitive that they have deeply unsettled even the scientists who study them.

Why do these theories inspire both awe and unease? And what do they reveal about the origins of everything we know? This thought-provoking exploration examines why the question of “before the Big Bang” remains one of the most fascinating—and unsettling—frontiers in cosmology.
