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.
