Scientists pushed photons across the universe to test the speed of light—and found Einstein’s cosmic speed limit still holds ...

You can tell a lot about a material based on the type of light shining at it: Optical light illuminates a material's surface, ...

While the terms "quantum physics" and "Theory of Relativity" are used casually every day, not many people know what they really mean. Yet these theories have had a profound impact not only on science ...

Light and matter can remain at separate temperatures even while interacting with each other for long periods, according to new research that could help scale up an emerging quantum computing approach ...

While the terms "quantum physics" and "Theory of Relativity" are used casually every day, not many people know what they really mean. Yet these theories have had a profound impact not only on science ...

Physicists have managed to simulate a strange quantum phenomenon where light appears to arise from empty space a concept that until now has only existed in theory. Using cutting-edge simulations, ...

A light has emerged at the end of the tunnel in the long pursuit of developing quantum computers, which are expected to ...

A simple question with a profound answer: why is space dark? It's not about a lack of light; billions of stars flood the universe with it. The secret lies in the one thing Earth has that space doesn't ...

Light can do more than illuminate a material. In some cases, it can temporarily change how electrons move through it.
