So I've been familiar with the basics of polarization since forever, but I recently realized circular polarization is a mystery to me. I've heard of it in conjunction with eg satellite broadcasts, but ...

Or rather, is it possible to collide two energy particles in such a way that the result is a photon with specific known properties (e.g. direction, speed)? What I'm thinking of is the ability to cause ...

Intergalactic gas clouds are slightly hotter than they should be, new research claims, and theoretical particles called 'dark photons' could explain it. When you purchase through links on our site, we ...

Scientists working on CERN’s Compact Muon Solenoid (CMS) experiment have published the latest data in their search for a long-lived exotic particle known as the dark photon. Dark photons (also called ...

Photons are particles of light, or waves, or something like that, right? [Mithuna Yoganathan] explains this conundrum in more detail than you probably got in your high school physics class. While ...

The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to a situation in which it is impossible to describe the physics of each photon separately ...

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

A gas made of particles of light, or photons, becomes easier to compress the more you squash it. This strange property could prove useful in making highly sensitive sensors. While gases are normally ...
