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 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 ...

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 ...

One of the strangest ideas about the nature of the universe could be one of the most important. Do long, thin, and incredibly dense strands of matter called cosmic strings wind their way throughout ...

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 ...

Brian Greene is one of the foremost scientists and science communicators of our time. Greene, a theoretical physicist at Columbia University, has been working for decades to advance our understanding ...

The problem with string theory, according to some physicists, is that it makes too many universes. It predicts not one but some 10 500 versions of spacetime, each with their own laws of physics. But ...

In the late 19th century, classical physics seemed complete. Scientists believed they had uncovered all the laws governing the universe, which appeared to operate like a precise machine. But ...

New research from a CU Boulder physicist might break open the mathematical puzzle that has stalled string theory research for decades A University of Colorado Boulder physicist is one step closer to ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. It's one of the most brilliant, controversial and unproven ideas in all ...
