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 has been famously untestable for decades. This week the Economist reported that has changed, and the reason ...

A philandering string theorist is caught with another woman by his wife. “But darling,” he pleads, “I can explain everything!” I didn’t invent the joke; it appeared in the satirical magazine The Onion ...

Dark energy might be getting weaker. Scientists are wondering if interactions with dark matter in a “dark dimension” may be ...

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 ...

IT IS one of the biggest questions confronting physics: why is our universe the way it is? If some of the fundamental laws were even slightly different, our universe would be a strange and lethal ...

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 ...

While the novel theory may never live up to the early hype, its innovative tools have helped scientists for decades, and the best may be yet to come. String theory was once the hottest thing in ...

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 ...
