gravity

Quantum entanglement could in theory lead to extremely precise clocks that can hunt for subtle disturbances in space-time.

Bumblebee gravity could explain dark energy — if it's proven true.

New research proposes that the first black holes came from clumps of gravitinos, exotic, hypothetical particles that managed to survive the first chaotic years of the Big Bang.

Scientists have mapped the "arches of chaos:" a vast network of arching structures filling the solar system that could one day aid space travel.

Einstein's failed dream could ultimately become his ultimate triumph, as a small group of theoretical physicists rework his old ideas to explain the most pressing issues of modern science.

If teensy black holes could be produced inside the world's largest atom smasher, the Large Hadron Collider, that would be a boon for physics.

A new test of Albert Einstein's theory of general relativity has proved the 20th Century physicist right again, this time using a supermassive black hole.

This supermassive black hole gobbled up a star in full view of Earth's telescopes, and could unlock secrets of how these monsters feed.

Can we blame gravity for one of quantum physics' most brain-numbing paradoxes — Schrödinger's cat?

Three physicists won a $3 million Breakthrough prize for a series of experiments that began using cheap equipment on a tabletop in Seattle and ended up hunting dark matter.
