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 ...

For decades, physicists have chased the dream of unifying all of nature’s forces under a single theory. String theory has long been a top candidate, offering a single mathematical framework that could ...

For decades, scientists have taken issue with “string theory” — a theory of the universe which contends that the fundamental forces and matter of nature can be reduced to tiny one-dimensional ...

Recent advances in theoretical physics have highlighted the central role of chaotic dynamics in understanding black hole phenomena and string theory. Chaotic behaviour, characterised by a sensitive ...

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 theory, conceptualized more than 50 years ago as a framework to explain the formation of matter, remains elusive as a "provable" phenomenon. But a team of physicists has now taken a significant ...

Quantum field theory (QFT) remains the cornerstone of our understanding of particle interactions, unifying the principles of quantum mechanics with special relativity by describing particles as ...

Event display in the signal region from data taken in 2018. The pixel tracklet candidate with p T = 1.2 TeV is shown by the red solid line and other inner detector tracks by the thin orange lines.

If you can't sleep at night worrying about gravity's ongoing conflict with the other three fundamental forces of nature, Lisa Randall may be able to help. Randall, a theoretical physicist at Harvard ...

A decade ago astrophysicists at the Laser Interferometer Gravitational-Wave Observatory (LIGO), operated by the California Institute of Technology and the Massachusetts Institute of Technology, ...
