String theory, simultaneously one of the most promising and controversial ideas in modern physics, may be more capable of helping probe the inner workings of subatomic particles than was previously ...

Physicists looking for a way to test their theory about strings might make more progress if they tangle them up. String theory — equations that aspire to explain all of nature’s particles and forces — ...

Today's physicists are struggling with a quandary. They have accepted two separate theories that explain how the universe works: Albert Einstein's general theory of relativity, which describes the ...

Physicists who have been roaming the “landscape” of string theory—the space of zillions and zillions of mathematical solutions of the theory, where each solution provides the kinds of equations ...

String theory is a purported theory of everything that physicists hope will one day explain … everything. All the forces, all the particles, all the constants, all the things under a single ...

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 ...

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 ...
