Gravitational distortion of time helps tell modified gravity apart from a dark force

The gravitational field can affect space and time: the stronger gravity is, the slower time moves. This prediction of General Relativity can be used to reveal hidden forces acting on dark matter.

Why Einstein must be wrong: In search of the theory of gravity

Einstein’s theory of general relativity suggests that our universe originated in a Big Bang. But black holes, and their gravitational forces, challenge the limits of Einstein’s work.

Researchers dig deep underground in hopes of finally observing dark matter

To detect dark matter, you need to build an ultra-sensitive detector and put it somewhere ultra-quiet. For one physics collaboration, that place is almost a mile under Lead, S.D.
