Scientists think a new framework for quantum gravity could offer clues about a mysterious 5th fundamental force of nature.

Dark matter is one of the biggest mysteries in science. It cannot be seen directly because it does not emit, absorb, or ...

Physicists in the US have used a tabletop experiment to rule out the existence of strong, gravitational-like forces at short length scales. Such forces, which could hint at additional space–time ...

In many people’s minds, the primary focus of physics is on the very large (black holes, the distant universe and the problems of cosmology) or the very small (the Higgs boson and the other subatomic ...
