A polarization-switchable array could be the building block for future energy-efficient photonic computers.

Why does lead behave so differently from every other atomic nucleus when struck by electrons? A team of physicists at ...

In 1845, Michael Faraday discovered what’s known today as the Faraday Effect—which describes how light and electromagnetism ...

The constancy of the speed of light is a pillar of modern physics, but questions persist about its absolute universality.

The famous double-slit experiment brings into question the very nature of matter. Its cousin, the quantum eraser experiment, ...

How confusing inevitability with reality built decades of paradox. What if general relativity never actually tells us that ...

Shattered glass does not leap back into your hand. Smoke from a match does not gather itself and crawl back inside. In ...

Researchers discovered that when atoms interact and remain entangled with light, they emit stronger, more coordinated bursts ...

Speed matters. When an X-ray photon excites an atom or ion, making a core electron jump onto a higher energy level, a ...

Physicists tested light speed using cosmic gamma-ray bursts. Study confirms Einstein's prediction that all light colors travel at same speed.

A YouTuber built a 2-billion-fps camera that can record the propagation of light, which has led to some very unique ...
