String theory has finally made a prediction that can be tested with experiments -- but in a completely unexpected realm of physics. The theory has long been touted as the best hope for a unified ...

In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical ...

Stop. Look around. All things, visible or not, are made of particles so tiny that many find their sizes difficult to comprehend. Far removed from our everyday experiences, they move at rapid speeds ...

Imagine you are sitting in a big symphony hall, and you’re listening to an orchestra play for the first time. The orchestra is performing a Violin Concerto by Beethoven. As the soloist runs her hands ...

The physicist Subir Sachdev borrows tools from string theory to understand the puzzling behavior of superconductors. String theory was devised as a way to unite the laws of quantum mechanics with ...

It's one of the most brilliant, controversial and unproven ideas in all of physics: string theory. At the heart of string theory is the thread of an idea that's run through physics for centuries, that ...

For decades, physicists have been trying to combine quantum physics and general relativity into a single, unified theory. One of the leading contenders is string theory, an elegant vision in which ...
