"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 ...

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

A groundbreaking study has challenged centuries of scientific consensus, potentially unravelling our understanding of how light behaves. Research from the Max Planck Institute for Quantum Optics may ...

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 ...
