Light and matter can remain at separate temperatures even while interacting with each other for long periods, according to ...

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

A nanostructure made of silver and an atomically thin semiconductor layer can be turned into an ultrafast switching mirror ...

Astronomers found evidence that dark matter and neutrinos may interact, hinting at a "fundamental breakthrough" that ...

Like stretch marks left on skin that expanded too quickly or cracks embedded in freezing ice, cosmic strings are artifacts of ...

A 'boom' of light that appears when a particle exceeds the speed of light set by a medium could, in other contexts, signal a ...

Why do light bulb filaments slowly disappear over time? 💡 This video explores the physics behind evaporating light bulb filaments, explaining how high temperatures, material properties, and atomic ...

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

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

What if you could create new materials just by shining a light them? To most, this sounds fantastical, but to physicists ...

The protostar is launching the longest outburst ever seen at 32 light-years long.
