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

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 ...

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 ...

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 ...

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 ...

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 ...
