The glow from faster-than-light particles gives us a unique way to explore the universe. Nothing can travel faster than light — in a vacuum. But when light slows down, sometimes matter can blaze past ...

A jet of particles released by two colliding stars appears to be moving seven times faster than the speed of light — but astronomers blame a cosmic illusion known as superluminal motion. When you ...

Nothing can travel faster than light, or 299,792,458 meters per second. But a certain group of particles acts as if it can, a team of physicists recently concluded, potentially paving the way for a ...

Light propagating in an optical fibre can make a tiny glass sphere nearby twist around on its axis. A theoretical analysis now explains why — and unexpectedly shows that the effect does not require ...

Slowing down light is not as easy as it sounds. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The phenomenon of light slowing down as it passes ...

In a major breakthrough, scientists have observed a strange and previously theoretical form of light — known as negative light. This marks the first time in human history that such a phenomenon has ...
