The proof of the existence of parallel universes has long been hindered by the core issue of "unobservable and difficult to ...

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 theory ...

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, "The ...

Researchers are demonstrating that, in certain contexts, string theory is the only consistent theory of quantum gravity. Might this make it true? Thirty years have passed since a pair of physicists, ...
