Just months after their discovery, gravitational waves coming from the mergers of black holes are shaking up astrophysics.

The astrophysicist Tracy Slatyer is searching for faint wisps of dark matter annihilating in the early universe — and perhaps in hiding places closer to home.

The absence of supersymmetry particles at the Large Hadron Collider has settled a 16-year-old bet among physicists.

A discrepancy in the measured size of the “deuteron” increases the chance that something is amiss in our understanding of atoms.

Physicists are confronting their “nightmare scenario.” What does the absence of new particles suggest about how nature works?

The physicist-mathematician Miranda Cheng is working to harness a mysterious connection between string theory, algebra and number theory.

A hint that neutrinos behave differently than antineutrinos suggests an answer to one the biggest questions in physics.

The physicist Asimina Arvanitaki is thinking up ways to search gravitational wave data for evidence of dark matter particles orbiting black holes.

According to our best theories of physics, the universe is a fixed block where time only appears to pass.
