There is a silence in the night sky that has bothered me for as long as I can remember. ” That line, attributed to Richard ...

New research suggests that relic black holes from before the big bang may still shape galaxies today. These black holes could explain dark matter, one of the biggest unsolved questions in cosmology.

When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen. In 1935, ...

In a new study published in Classical and Quantum Gravity, researchers have revisited the concept of Einstein-Rosen bridges, the theoretical structures often associated with wormholes. This study, ...

Wormholes may help solve a major physics paradox, the conflict between quantum mechanics and general relativity. The “direct-sum quantum theory” views spacetime as distinct but related regions.

Generally speaking, black holes are regions of spacetime where matter is compressed into a tiny space. Dark matter, meanwhile ...
