Modern physics theories highlight the key role of horizons—boundaries beyond which information cannot reach an observer—in a ...

This video explores the complexities and challenges faced by scientists in understanding fundamental physics concepts.

An international team led by Innsbruck quantum physicist Peter Zoller, together with the US company QuEra Computing, has directly observed a gauge field theory similar to models from particle physics ...

DURHAM, N.C. – Using lasers to contain some ultra-chilled atoms, a team of scientists has measured the viscosity or stickiness of a gas often considered to be the sixth state of matter. The ...

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 ...

String theory and its extensions propose that the elementary constituents of matter are not point particles but one-dimensional strings whose vibrational modes manifest as observed particles and ...

String field theory is a second-quantised framework that recasts the perturbative dynamics of strings in terms of field-theoretic variables on the space of string configurations. By organising ...
