A close look at fundamental symmetries has exposed hidden patterns in the universe. Physicists think that those same symmetries may also reveal time’s original secret.

The astronomers Michel Mayor and Didier Queloz won half of the prize for their 1995 discovery of a Jupiter-like planet orbiting a nearby star. The cosmologist James Peebles won the other half for work exploring the structure of the universe.

Fifty years after the current internet was born, the physicist and computer scientist Stephanie Wehner is planning and designing the next internet — a quantum one.

A new measurement appears to have eliminated an anomaly that had captivated physicists for nearly a decade.

Researchers have confirmed rumors of a black hole collision that challenges our ideas about how black holes form.

New measurements could upend the standard theory of the cosmos that has reigned since the discovery of dark energy 21 years ago.

A new look at a ubiquitous phenomenon has uncovered unexpected fractal behavior that could give us clues about the early universe and the arrow of time.

Although Einstein’s theory of space-time seems more complicated than Newtonian physics, it greatly simplified the mathematical description of the universe.

Opinions differ about what recent measurements of a sound-trapping fluid reveal about light-trapping black holes.
