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 ...

Columnist Natalie Wolchover examines the latest developments in the “forever war” over whether string theory can describe the ...

Could the universe have hidden dimensions we’ve yet to detect? The idea of extra dimensions has intrigued physicists for over a century, and while there’s no solid evidence to prove their existence, ...

Peering backward in time to an instant after the big bang, physicists at the University of Wisconsin-Madison have devised an approach that may help unlock the hidden shapes of alternate dimensions of ...

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 ...

Most people are perfectly content with three dimensions to carry out daily tasks -- or four if they take time into account. String theorists, on the other hand, think that many more dimensions are ...

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 ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. String theory is perhaps the most controversial big idea in all of ...
