The spokesperson for the Laser Interferometer Gravitational-Wave Observatory called it “a promising start to mapping the populations of black holes in our universe.”

What could cause galaxies millions of light years apart to all spew material in the same direction?

A group of little-known Hungarian physicists claim to have found a new fundamental particle. Now other researchers are raising questions about the team’s past work.

Suchitra Sebastian’s searches for quantum anomalies have led to the potential discovery of a new building block of matter.

A lab in Hungary has reported an anomaly that could lead to a physics revolution. But even as excitement builds, closer scrutiny has unearthed a troubling backstory.

The astrophysicist, conceptual writer and host of standing-room-only scientific soirees at a repurposed factory in Brooklyn sees science as a powerful force in culture.

The search for exotic new physical phenomena is being led by huge experiments like the Large Hadron Collider. But at the other end of the spectrum lie tabletop experiments — small-scale probes of hidden dimensions, dark matter and dark energy.

How quantum entanglement connects with the “many worlds” of quantum theory.

The story of the universe’s birth — and evidence for string theory — could be found in triangles and myriad other shapes in the sky.
