Physicists from Imperial College London have achieved a groundbreaking milestone in quantum physics by reimagining the ...

Can we turn back time? Ask a savvy physicist, and the answer will be “it depends.” Schemes for retrograde time travel abound but usually involve irreconcilable paradoxes and rely on outlandish ...

Black holes can’t be formed from pure light. Quantum physics would curb their creation under any foreseeable conditions, a new study suggests. Typically, matter is responsible for black holes. They’re ...

Observations of the formation of light-nuclei from high-energy collisions may help in the hunt for dark matter.

The 2023 Nobel Prize in physics has been awarded to three scientists who created pulses of light so short they can be used to watch the inner workings of atoms. Pierre Agostini, Ferenc Krausz, and ...

Far beneath the Black Hills of South Dakota, a tank of liquid xenon is quietly recording some of the faintest signals in the ...

Researchers at the University of Sydney have cracked a long-standing problem in microchip-scale lasers by carving tiny "speed ...

From the pristine dark of his backyard in rural Alberta, Canada, Alan Dyer has taken stunning photos of a rare sky glow called STEVE. To capture this ribbon of mauve, he and other citizen scientists ...

Because dark matter is completely invisible to light, science had to look for clever new methods to spot it.

Researchers have found a razor-thin, rotating string of galaxies inside a massive cosmic filament, revealing unexpected ...
