Physicists have built a ring in which pulses of light whip circles around each other and the normal rules that govern light's behavior stop applying.

All the light that has ever been created is still lurking among the stars.

Once again, a decades-old theory of gravity has survived a modern scientific onslaught. Einstein wins again.

Just seven photons in a mirrored trap formed a Bose-Einstein condensate, one of the more exotic particle states — and one usually reserved for matter.

Light has momentum, and scientists can hear it.

The strange radio bursts usually circle the Earth like electromagnetic ghosts, but scientists have now created and studied their shapes in a plasma chamber on Earth.

The technology could improve future precision light sources. But right now the biggest surprise is how many holes there are in a laser figure-eight.

Be careful where you leave your water bottles this summer.

If you draw lightning bolts like crooked zigzags, then you're doing it wrong — but at least you're in good company. Artists have drawn lightning incorrectly for hundreds of years, a new study finds.
