Faster-than-light particles have spent decades in physics as both temptation and warning. They offered a way to test the ...

Space and time looked settled, at least in broad outline. Einstein’s special relativity gave physics a durable framework for ...

On May 29, 1919, a total solar eclipse helped to prove Albert Einstein's theory of general relativity. [‘On This Day in Space ...

Black holes, regions in space where gravity is so strong that nothing can escape, have been widely studied over the past ...

In holographic theories, physicists may have traced the pliability of space-time to its quantum roots: a measure of ...

Despite AI's dizzying improvements in mathematical ability, its successes show just how integral human mathematicians are to ...

The speed of light remains one of physics’ firmest assumptions, but scientists still test whether it ever shifts under ...

Tenets of quantum mechanics and special relativity, among other theoretical ideas, lead inexorably to string theory.

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...

A total solar eclipse will occur on August 12, visible in parts of Greenland, Iceland, Spain and Portugal.

Physicists searching for a better understanding of quantum gravity stumbled upon something unexpected: the defining signatures of string theory.

A rewrite of quantum mechanics that includes the force of gravity could finally achieve one of physicists’ biggest goals and ...
