Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

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 ...

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

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 ...

Scientists have observed a unique particle that moves easily one way, yet resists at 90 degrees. These semi-Dirac fermions were observed using their energy signature in a topological metal. Particles ...

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.

By tracing solar flare gamma rays, scientists gain new insight into particle behavior that shapes space weather forecasts.

Wildfire smoke is no longer just a short‑lived air quality problem drifting over cities for a few hazy days. New research ...
