Why Black Holes Might Contain Another Universe | Leonard Susskind

Описание: Black holes are usually described as cosmic endpoints — regions where matter collapses into a singularity and spacetime comes to an end. But modern theoretical physics suggests something far more radical.

What if a black hole is not the end of a universe, but the beginning of another?

In this video, we explore how ideas associated with Leonard Susskind and modern quantum gravity challenge the classical picture of black holes. The traditional view predicts a singularity — a breakdown of physics. But newer approaches, including holography and information theory, suggest that this may not be the full story.

Black holes preserve information. They have entropy. They behave like thermodynamic systems. And some theoretical models propose that what looks like collapse from the outside could correspond to expansion from the inside.

In certain speculative but mathematically consistent frameworks, the interior of a black hole may evolve into a new region of spacetime — effectively a new universe with its own geometry and arrow of time.

This does not mean we have discovered another universe. It means the structure of gravity leaves open the possibility that black holes are not cosmic graves, but cosmic seeds.

The event horizon may be a boundary between different descriptions of reality. What appears as destruction from one perspective may be creation from another.

Black holes may not end spacetime. They may generate it.
