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 ...

Physicists searching for a better understanding of quantum gravity stumbled upon something unexpected: the defining signatures of string theory.

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 ...

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 ...

String theorists are shifting focus to solve some rather sticky problems in physics. Over the past few years, string theory has been less about trying to find a unifying description of all forces and ...

Visualization of the allowed values of "dial settings" in the scattering amplitudes that describe the probability for particles to interact in the models introduced in this new work. The regions in ...

Physicists who have been roaming the “landscape” of string theory—the space of zillions and zillions of mathematical solutions of the theory, where each solution provides the kinds of equations ...

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 ...

Scientists have found what they say is a link between complex number theory and string theory. A mathematician and physicist working together found the connection, which they say is part of plotting ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American I just won a bet I made in 2002 with ...
