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.

An experiment claims to have invalidated a decades-old criticism against pilot-wave theory, an alternative formulation of quantum mechanics that eliminates the most baffling features of the subatomic universe.

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.

In the new, free-for-all era of dark matter research, the controversial idea that dark matter is concentrated in thin disks is being rescued from scientific oblivion.

A satellite spotted a burst of light just as gravitational waves rolled in from the collision of two black holes. Was the flash a cosmic coincidence, or do astrophysicists need to rethink what black holes can do?

In a virtuoso experiment, physicists have revealed details of a “quantum critical point” that underlies high-temperature superconductivity.
