The speed of light is one of the most fundamental constants in physics, yet it has never been directly measured in one ...

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

Properties that remain unchanged when materials are stretched or bent, which are broadly referred to as topological ...

A new theory of "dark photons" attempted to explain a centuries-old experiment in a new way this year, in an effort to change ...

Quantum physics is arguably the greatest intellectual triumph in the history of human civilization, but to most people it seems like it's too remote and abstract to matter. This is largely a ...

Light's behavior seems counterintuitive. That is, until you figure out light is a wave. The way light behaves can seem very counterintuitive, and many physicists would agree with that, but once you ...

A new laser based on a swirling vortex of light has been created by physicists in the US. The “topological-defect laser” could be a useful addition to lab-on-a-chip devices, where it could manipulate ...
