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.
New experimental results simultaneously advance and challenge the theory that the brain’s network of neurons balances on the knife-edge between two phases.
A recent challenge to Stephen Hawking’s biggest idea — about how the universe might have come from nothing — has cosmologists choosing sides.
An experiment caught a quantum system in the middle of a jump — something the originators of quantum mechanics assumed was impossible.
A new theoretical model may help explain the shocking onset of superconductivity in stacked, twisted carbon sheets.
