S301 orbits Sagittarius A at 25,000 km/s, close enough that the black hole's rotation twists spacetime. Years of tracking should yield the first direct spin measurement.

A new experimental design suggests that scientists could exchange energy between laser beams and gravitational waves to prove that gravity is made of tiny individual particles called gravitons.

Researchers develop a unified guide to identify tiny distortions in space and time, linking quantum physics and gravity theories with measurable signals in current tools.

Researchers solve a decades-old problem by using equations from universes with infinite dimensions to understand critical states in our own spacetime.

Joe Rogan hosted Hal Puthoff, a physicist renowned (or maligned) for his work in unconventional scientific areas.

Ten years after detecting the first ripples in space-time, scientists have analyzed gravitational wave signals and confirmed Stephen Hawking's black hole area theorem.

Physicists have suggested that primordial naked singularities contribute to dark matter and could be observed.

NASA's James Webb Space Telescope finds most deep-space galaxies rotate clockwise, challenging ideas about the universe.
