light

A human-made thing created a very beautiful, natural pattern.

Imagine sitting down to dinner with a group of friends, when a laser tickles the water molecules inside your ear. "Hello!" you hear.

A laser pulse glanced off a rubidium atom and entered the quantum world — taking on the weird physics of Schrödinger's cat.

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.
