Physics

Physicists have shown how a particle might show its face in a corner of an experiment without needing its body anywhere in sight, like a grin without a cat.

Did the creator of the universe leave a hidden message in the cosmos for intelligent life? If so, scientists have yet to find it. But at least one is still trying.

"Jiuzhang" would be the most powerful quantum computer in the world, capable of performing some tasks 100 trillion times faster than the world's fastest supercomputers.

For more than a billion years, Earth covered itself in new continents. New research shows that those continents were quickly swallowed up again but their deaths fertilized life on the surface.

If teensy black holes could be produced inside the world's largest atom smasher, the Large Hadron Collider, that would be a boon for physics.

For the first time, physicists have recorded sound waves moving through a perfect fluid with the lowest possible viscosity.

What if dark matter weren't a new type of matter at all, but huge swarms of tiny, "primordial" black holes?

A device demonstrated in a groundbreaking new experiment acts like a laser, only backwards. And someday it might send power invisibly through the air.

A new mathematical framework helps physicists define the degree of quantumness of a system

Two neutron stars slammed together far away from Earth, and the Hubble may have spotted a magnetar emerging from the aftermath.

New theory suggests cosmic bubbles during the birth of our universe are responsible for creating dark matter.

OSIRIS-REx finished stowing the bits of the asteroid Bennu that it snagged last week, successfully locking the material into the spacecraft's return capsule

This supermassive black hole's spin has been measured for the first time, and it's surprisingly low.

A pair of astronomers is advocating a daring new research program: to turn our widening search for life beyond Earth into a hunt for dark matter.

Humans have gotten good at spotting planets orbiting alien stars. But how many of those alien stars are able to look back and see us?

Starman — the dummy riding a Tesla Roadster through space — has made his closest approach ever to Mars since his stunt launch in 2018.

Physicists suggest harnessing the gravitational pull of black holes to create ferocious particle accelerators. The trick? Carefully set everything up so the particles don't get lost forever.

Back in 2016, researchers claimed Dragonfly 44 was a "failed" Milky Way — a galaxy with a huge dark matter mass but almost no stars. Now, on closer examination, that claim has fallen apart.
