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 ...

Dimensions beyond the four we’re familiar with could solve a host of problems in physics and cosmology. Columnist Leah Crane ...

Columnist Natalie Wolchover examines the latest developments in the “forever war” over whether string theory can describe the ...

Most people are perfectly content with three dimensions to carry out daily tasks -- or four if they take time into account. String theorists, on the other hand, think that many more dimensions are ...

Gravity is by far the weakest of nature’s four fundamental forces, and physicists have spent decades asking a deceptively ...

Scientists seeking the secrets of the universe would like to make a model that shows how all of nature’s forces and particles fit together. It would be nice to do it with Legos. But perhaps a better ...

String theory proposes that the fundamental constituents of the universe are one-dimensional “strings” rather than point-like particles. What we perceive as particles are actually vibrations in loops ...

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 ...
