So rather than just slapping a beard on Mirror Universe Spock, Star Trek should have depicted a universe in which up is down and the laws of physics operate in entirely different ways.

However, Everett conceived of the parallel universes representing alternate histories of our given universe as existing independently without influencing or interacting with each other.

No braner: there is no evidence that ILL neutrons venture into an adjacent universe. (Courtesy: Louise Mayor) The first results from a detector designed to look for evidence of particles reaching us ...

One version of parallel universes that cosmologists consider is the so-called ‘Multiverse,’ which is a consequence of the dominant theory of cosmic genesis known as inflation.

Time to break out your theoretical physics cap for a moment. A new idea about the cause of neutron loss (a phenomena in which neutrons seem to momentarily disappear), is pushing the boundaries of ...

The idea of aliens hiding in a parallel universe — though seemingly absurd — is presented as a way to bridge the gap between theoretical physics and the search for extraterrestrial life.

Yes, modern physics and math actually indicate parallel universes are pretty likely — the big question is how to prove it.

Physics theories can get pretty hairy, but don’t worry: If our universe isn’t the only one—if in fact there are an infinite number of universes out there—then in at least one of them you ...

In “The Dream Universe,” David Lindley argues that physicists have become too enamored of theoretical phenomena like parallel universes and black holes.

Plausibility score: Physics churns out parallel universes with ease, but accessing or having aspects of alternative realms invade our universe appears to be the stuff of fantasy.
