Tiny, dim “dwarf” galaxies have been found to hide gas-spewing black holes.

Researchers are getting close to building a quantum computer that can perform tasks a classical computer can’t. Here’s what the milestone will mean.

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

By studying a swarm of flying midges as though it were a fluid, physicists have learned how collective behaviors might stabilize a group against environmental disruptions.

Randomness would seem to make a mathematical statement harder to prove. In fact, it often does the opposite.

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

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

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.
