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 ...

First off, my name is a misnomer. I love physics like Lennie likes bunnies. So I was wondering today about the following: What happens to the photons that hit your eye and are recognized as light? The ...

Light is usually treated as something simple, a clean beam that either shines or does not. At the quantum level, however, ...

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 ...

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 ...

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

Michael Murdoch is a member and former board member of the Inter-Society Color Council, part of the Color Literacy Project. People love the rainbow of ROYGBIV colors: red, orange, yellow, green, blue, ...

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 ...
