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

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two ...

The quantum physics of massive particles has intrigued physicists for more than 80 years, since it predicts that even complex particles can exhibit wave-like behaviour – in conflict with our everyday ...

Physicists in Germany have generated what they call a "special" state of matter, using a three-dimensional optical interference pattern. Turning up the intensity of this pattern created a gaseous ...

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of ...

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew.

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...
