"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of physics.

Physics experiments have changed the world irrevocably, altering our reality and enabling us to take gigantic leaps in technology. From ancient times to now, here's a look at some of the greatest ...

A photon was apparently detected in two places at once in a twist on the classic double-slit experiment, but many physicists ...

Physicists have finally confirmed a phenomenon that sounds like pure science fiction: waves that appear to bounce off a sudden change in time rather than a surface in space. The effect, known as a ...
