A 13th-century bishop's theory about the formation of the universe has intriguing parallels with the theory of multiple universes.

Eternal chaotic inflation, which generates multiple universes, builds from the theory of cosmic inflation, originated by physicist Alan Guth at the Massachusetts Institute of Technology.

A work to be published in the Physical Review D posits a test, and some interesting conclusions, for multiverse theory. Multiple, or alternate, universes might, less excitingly, be called 'very ...

In fact, in some of Linde's mathematical models, cosmic inflation must be expanding eternally and chaotically. Cosmic inflation Eternal chaotic inflation, which generates multiple universes, builds ...

The increasingly popular theory of Many Worlds suggests every fundamental event has multiple possible outcomes and splits the world into various realities.

Before his death on March 14, theoretical physicist Stephen Hawking was deep in thought about the possibility of universes that exist well beyond our own — places with completely unknown ...

If the theory of parallel universes with multiple timelines is correct, time travel would be a possibility. The idea could mean that in some universes, the asteroid that killed the dinosaurs ...

The multiverse theory, that our universe is one of multiple or bubble universes, may be testable according to a new study that aims to verify the theory of eternal inflation.

Just not in this particular universe. I’m talking about the multiverse theory; the mind-bending idea that there are many if not innumerable other universes beyond our own.
