Which Universe Are We In?

Episode 17 of 19

Until very recently the whole idea of the multiverse was dismissed as fantasy. Horizon asks whether multiple universes exist and, if so, which one we are actually in.

Imagine a world where dinosaurs still walk the earth. A world where the Germans won World War II and you are president of the United States. Imagine a world where the laws of physics no longer apply and where infinite copies of you are playing out every storyline of your life.

It sounds like a plot stolen straight from Hollywood, but far from it. This is the multiverse.

Until very recently the whole idea of the multiverse was dismissed as a fantasy, but now this strangest of ideas is at the cutting edge of science.

And for a growing number of scientists, the multiverse is the only way we will ever truly make sense of the world we are in.

Horizon asks the question: Do multiple universes exist? And if so, which one are we actually in?
