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

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 ...

For more than a century, the double-slit experiment has been the sharpest test of what reality is made of, and of whether ...

A physicist has proposed a bold experiment that could allow gravitational waves to be manipulated using laser light. By ...

A new concept for energy transfer between gravitational waves and light. When massive cosmic objects such as black holes merge or neutron stars crash into one another, they can produce gravitational ...

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 ...
