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 ...

Physicists have engineered photons that behave as if they inhabit a space far richer than the familiar three dimensions, ...

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 ...

The time-flipped photon can't be used to restage "Back to the Future," but it could help us figure out some of the universe's most mysterious phenomena. When you purchase through links on our site, we ...

In the early 1960s, a new class of astronomical object known as the quasi-stellar radio source, or quasar, was revealed. As the name suggests, early observations noted that these objects looked like ...

Physicists have created a one dimensional gas out of light particles for the first time. Studying how the photon gas behaves could help researchers discover some yet-unknown quantum optical effects.
