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 ...

Physicists are exploring the idea that our universe may have more dimensions than the three of space and one of time we experience. String theory suggests these extra dimensions are essential for ...

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 ...

For decades, scientists have taken issue with “string theory” — a theory of the universe which contends that the fundamental forces and matter of nature can be reduced to tiny one-dimensional ...
