The fact that no one knows the answer to this question is what makes it exciting. The story of physics has been one of an ever-expanding understanding of the sheer scale of reality, to the point where physicists are now postulating that there may be far more universes than just our own. Chris Anderson explores the thrilling implications of this idea. [Directed by Andrew Park, narrated by Chris Anderson].

Chris Anderson: How many universes are there?

How many universes are there?

Our universe, vast beyond imagination, fits a million Earths in the sun, yet is merely a drop in the cosmic ocean of galaxies.

Exploring the cosmos reveals our sun's immensity: fitting a million Earths inside, yet a speck in the Milky Way's 400 billion stars.

Physics suggests a multiverse of up to 10^500 universes, far beyond our observable reality, challenging our understanding of existence.
