A hint that neutrinos behave differently than antineutrinos suggests an answer to one the biggest questions in physics.
Suchitra Sebastian’s searches for quantum anomalies have led to the potential discovery of a new building block of matter.
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 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.
In a virtuoso experiment, physicists have revealed details of a “quantum critical point” that underlies high-temperature superconductivity.
The physicist Gabriela González is on the cusp of finding the first direct evidence of gravitational waves — soundlike wobbles in space-time produced by black holes and their kin.
Is dark energy a cosmic chameleon that can fade into its surroundings? A recent test brings the mysterious anti-gravitational force down to earth.
Surprising oil drop experiments suggest that the quantum world may not be as strange as advertised.
Physicists have completed a new round of searches for the answer to why matter dominates over antimatter. But the radioactive decay that would solve the puzzle is evading them.
