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 second dimension of time has long seemed wholly incompatible with reality. But fresh insights involving black holes and ...

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 ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it? String theorists, this one may be for you. The theorized object warps spacetime ...

Some string theorists predict at least 10 dimensions, most of which humans can’t perceive. | Andriy Onufriyenko/Moment/Getty Images Ask someone to name every ...

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 ...

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 ...
