Some physicists claim the popular landscape of universes in string theory may not exist.

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 its own laws of physics. But ...

String theory says we may be living in a universe where reality meets science fiction: A universe of 11 dimensions, with parallel universes right next-door. An elegant universe composed entirely ...

Some physicists claim the popular landscape of universes in string theory may not exist.

An curved arrow pointing right. CalTech theoretical physicist Sean Carroll stopped by BI to talk about string theory, parallel universes, and other exciting topics he discusses in his new book ...

As part of ongoing efforts to derive a scientifically testable multiverse theory, a team of researchers proposed recently that parallel universes exist and that they influence each other. The ...

Then there’s String Theory’s take, that we exist on a three dimensional plane inside of a larger nine-dimensional universe, wherein other three dimensional “membranes” (universes) could exist.

In universes with a fisheye geometry known as anti-de Sitter space, string theory has been shown to provide the only consistent way to reconcile gravity and quantum mechanics.
