Let’s Begin…

Everyone loves the idea of parallel universes— maybe it’s the appeal of an ideal world where you have second chances and things turn out differently or an alternate reality where you do get into Hogwarts. But is there really a place in science for such wistful speculation? Minute Physics digs into the science of parallel universes.

Take a look at some of the mind-bending science behind multiverses, as seen through popular science fiction movies and stories.

Why do physicists overwhelmingly claim that a multiverse must exist? Dive into the theory of inflation and learn why it makes the multiverse all but inevitable. 

The notion of parallel universes leapt out of the pages of fiction into scientific journals in the 1990s. Many scientists claim that mega-millions of other universes, each with its own laws of physics, lie out there, beyond our visual horizon. They are collectively known as the multiverse.

The trouble is that no possible astronomical observations can ever see those other universes. The arguments are indirect at best. And even if the multiverse exists, it leaves the deep mysteries of nature unexplained.
