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

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

Controlling light at dimensions thousands of times smaller than the thickness of a human hair is one of the pillars of modern ...

Why does light carry energy even though it has no mass? This video explains the real physics behind photons, energy–momentum ...

The best time to hunt for Ursid meteors is from the evening of Dec. 21 straight through to dawn on Dec. 22. The shower's peak ...

I test a series of light experiments to explore reflection, refraction, and optical illusions, demonstrating how light behaves in surprising and educational ways.

Researchers have introduced an innovative two-step excitation approach that makes it possible to efficiently generate and clearly separate different modes of hyperbolic polaritons. An international co ...

Optical physics is the study of the fundamental properties of light and its interaction with matter. This includes classical optical phenomena such as reflection, refraction, diffraction and ...

Chris Wedel is a fan of all things tech and gadgets. Living in rural Kansas with his wife and two young boys makes finding ways to stay online tricky — not to mention making my homestead smarter.

A research paper proposes a fully physically realized model for warp drive. This builds on an existing model that requires negative energy—an impossibility. The new model is exciting, but warp speed ...
