After an interstellar asteroid shot past the sun, scientists realized that there’s probably a lot of itinerant rocks out there.

Although Einstein’s theory of space-time seems more complicated than Newtonian physics, it greatly simplified the mathematical description of the universe.

A recent test has confirmed the predictions of quantum trajectory theory.

Lee Smolin’s radical idea to reimagine how we view the universe.

Lurking behind Einstein’s theory of gravity and our modern understanding of particle physics is the deceptively simple idea of symmetry. But physicists are beginning to question whether focusing on symmetry is still as productive as it once was.

Opinions differ about what recent measurements of a sound-trapping fluid reveal about light-trapping black holes.

Pure, verifiable randomness is hard to come by. Two proposals show how to make quantum computers into randomness factories.

Neven’s law states that quantum computers are improving at a “doubly exponential” rate. If it holds, quantum supremacy is around the corner.

Astronomers have discovered a complex planetary system still swirling into existence.
