An early attempt to explain the concept of extra dimensions came in 1884 with the publication of Edwin A. Abbott's Flatland: ...

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 ...

The original version of this story appeared in Quanta Magazine. String theory captured the hearts and minds of many physicists decades ago because of a beautiful simplicity. Zoom in far enough on a ...

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 ...

String theory found its origins in an attempt to understand the nascent experiments revealing the strong nuclear force. Eventually another theory, one based on particles called quarks and force ...

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 ...

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 ...

In quantum field theory, spontaneous particle formation can occur when the potential energy between two elementary particles increases with their separation, as if they were confined by a string. When ...

In his classic book The Dragons of Eden, astronomer Carl Sagan tidily summarized the central challenge scientists face when they try to formulate grand new theories: “Remarkable claims require ...
