String theory's equations give rise to a near infinite variety of potential universes in a 'landscape.' This landscape is surrounded by a 'swampland' of solutions that are incompatible with any ...

Scientists still cannot explain what most of the universe is actually made of. Dark matter, string theory, and the biggest ...

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 ...

A new theoretical study suggests that the mysterious force driving the accelerated expansion of the universe—known as dark energy—may actually be rooted in a deeply quantum structure of space-time.

Some celestial bodies are so cold that methane freezes; others are so hot that nuclear reactions occur. And then there’s Earth, with a benign temperature hovering in the narrow range between freezing ...

The accelerating expansion of the Universe might not be just an unexplained phenomenon — according to a new proposal by theoretical physicists, it could be a fundamental feature woven into the very ...

String theory is the best candidate we have for a theory of everything. Bend to its rule and the various tangled theories of conventional physics emerge as part of a sublime, higher-dimensional ...

String theory is the most well known candidate for a theory of everything — a mathematical framework that would meld the world of the very small, described by quantum mechanics, and the very large, as ...
