CAMBRIDGE, Mass — Physicists are divided on whether string theory is a viable theory of everything, but many agree that it offers a new way to look at physical phenomena that have otherwise proven ...

Stanford math professor Keith Devlin talks about two new books that call into question the entire idea of string theory. The theory states that tiny vibrating strings make up everything, but some ...

String theory's equations give rise to a near infinite variety of potential universes in a 'landscape.' This landscape is surrounded by a 'swampland' of solutions that are incompatible with any ...

String theory is having trouble producing inflation – the rapid expansion of space thought to have occurred in the early universe – at least in some of the theory’s simplest incarnations, according to ...

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 ...

String theory, a mathematical construct aiming to unify physics, posits the existence of extra, curled-up dimensions. Public and media interest in string theory has waned in recent years, coinciding ...
