Physicists are using quantum math to understand what happens when black holes collide. In a surprise, they’ve shown that a single particle can describe a collision’s entire gravitational wave.
Celia Escamilla-Rivera is combining large data sets with supercomputers to test general relativity against its little-known competitors.
An enigmatic connection between the forces of nature is allowing physicists to explore gravity’s quantum side.
Spurred on by quantum experiments that scramble the ordering of causes and their effects, some physicists are figuring out how to abandon causality altogether.
Featuring paradoxical black holes, room-temperature superconductors and a new escape from the prison of time.
Cosmologists have concluded that the universe doesn’t appear to clump as much as it should. Could both of cosmology’s big puzzles share a single fix?
Claudia de Rham showed how theories of “massive gravity” could potentially get rid of the need for dark energy.
New calculations show how hypothetical particles called gravitons would give rise to a special kind of noise.
We asked four physicists why gravity stands out among the forces of nature. We got four different answers.
