In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical framework that describes nearly all particles and forces in the universe but ...

String theory solves many of the questions wracking the minds of physicists, but it has one major flaw — there are currently no known methods to test it. SLAC scientists have found a way to test a ...

Imagine a world unified by a single scientific principle, something that can explain life’s greatest mysteries, from the origin of space and time to gravity and smaller matters, like daydreams. Now ...

If extra dimensions of space exist, they must be smaller than about half the width of a human hair, according to new measurements of the strength of gravity at short distances. Researchers found that ...

It's one of the most brilliant, controversial and unproven ideas in all of physics: string theory. At the heart of string theory is the thread of an idea that's run through physics for centuries, that ...

The idea of String Theory is that our Universe came from a higher-dimensional, more symmetric, more complex state with an enormous number of degrees of freedom. In order for String Theory to be solved ...

String theory has finally made a prediction that can be tested with experiments -- but in a completely unexpected realm of physics. The theory has long been touted as the best hope for a unified ...

Does string theory excite you? Mathematically, it holds up. Aspects about it suggest not one but several different dimensions, ones we're not generally privy to, though we may be interacting with some ...

THIS is the history of science as if told by J.R.R. Tolkien or George Lucas. By chance, so the story goes, a piece of 21st-century physics, in the form of an elegant mathematical formalism known as ...
