Greene explains that when he began studying string theory and parallel universes, it wasn't because he could one day measure energy at CERN or develop new mathematical equations.

Researchers are using machine learning, symbolic regression, and high-performance computing to explore and classify string ...

Eternal inflation, the Big Bang theory and parallel universes. Around 13.7 billion years ago, everything we know of was an infinitesimal singularity.

And much as a, you know, circus, stars whip when that string-like entity wildly oscillates, it sends out a crack, a sound, the wild strings of string theory — they would send out another kind of ...

The problem with string theory, according to some physicists, is that it makes too many universes. It predicts not one but some 10 500 versions of spacetime, each with their own laws of physics ...

The final installment of a three-part NOVA series about "String Theory," a new branch of science that seeks to explain nothing less than how the universe works, airs on PBS. Ray Suarez speaks with ...

So, physicists accept parallel universes, sure, but even in the wildly theoretical world described by string theory, there are rules — and Into the Spider-Verse breaks a big one.

The universes predicted by string theory and inflation live in the same physical space (unlike the many universes of quantum mechanics which live in a mathematical space), they can overlap or collide.

It is possible that there are many other universes that exist parallel to our universe. Theoretical physicist Brian Greene, author of The Elegant Universe, explains how that's possible in the new ...
