"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 double-slit experiment is one of the most famous experiments in physics and definitely one of the weirdest. It demonstrates that matter and energy (such as light) can exhibit both wave and ...

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

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

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 ...
