Anyone who loves physics knows about String Theory. If, by some miraculous chance, you’ve never heard of it before…well, prepare to be introduced to one of the most interesting and highly contested ...

reviews the concepts of general relativity (Einstein's theory of gravity that describes the universe on a large scale) and quantum mechanics (a theory that describes the universe on a very small scale ...

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 ...

Theoretical physicist Brian Greene joined us for a Q&A today where he answered several of our most burning questions about string theory, starting with the most basic ...

String theory—the idea that particles are not point-like, but instead one-dimensional strings—is a popular theoretical framework that attempts to combine general relativity and quantum field theory ...

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 ...

But despite its extraordinary popularity among some of the smartest people on the planet, string theory hasn’t been embraced by everyone–and now, nearly 30 years after it made its initial splash, some ...

After the Eyjafjallajökull volcano erupted in Iceland in 2010, flight cancellations left Miranda Cheng stranded in Paris. While waiting for the ash to clear, Cheng, then a postdoctoral researcher at ...

NOVA: What is so compelling about string theory to make you want to devote your career to it? Lykken: I think when a lot of people go into theoretical physics, they're looking for the big answers to ...
