The speed of light is a fundamental constant, approximately 299,792,458 meters per second. It's the same for all observers and hasn't changed measurably over billions of years. Nothing can travel ...

Physicists in Toronto observe quantum “negative time”: a pulse of light appears to leave before entering atoms.

Squeezed light is a specialized form of light in which quantum fluctuations are redistributed between two complementary ...

In 1964, physicist John Bell formulated what became known as Bell's Theorem, showing that if quantum mechanics is correct, ...

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 ...

Gravity can turn itself into light, but only if space-time behaves in just the right way, a research team has found. Under normal circumstances, you cannot get something from nothing. Specifically, ...

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 ...
