What's up in
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.
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.
A proposal for building wormhole-connected black holes offers a way to probe the paradoxes of quantum information.
For the first time, physicists have calculated exactly what kind of singularity lies at the center of a realistic black hole.
