We asked four physicists why gravity stands out among the forces of nature. We got four different answers.
By chewing on the problems posed by “extremal” black holes, physicists have exposed a surprising and universal connection between energy and entropy.
Collider physicists report that several measurements of particles called B mesons deviate from predictions. Alone, each oddity looks like a fluke, but their collective drift is more suggestive.
Freeman Dyson — physicist, mathematician, writer and idea factory — died on February 28, but his vitality lives on.
The laws of physics imply that the passage of time is an illusion. To avoid this conclusion, we might have to rethink the reality of infinitely precise numbers.
In a new paper, physicists argue that hypothetical particles called axions could explain why the universe isn’t empty.
As the founding director of a new institute for fundamental research in Rwanda, the physicist Omololu Akin-Ojo hopes to stem the brain drain of Africa’s brightest minds.
A proposal for building wormhole-connected black holes offers a way to probe the paradoxes of quantum information.
Physicists saw a black hole for the first time, debated the expansion rate of the universe, pondered the origin of time and modeled the end of clouds.
