supergravity

Supergravity is really cool stuff that physicists use to learn more about how things work in the Universe. Basically, it's a special kind of gravity that is so strong that it works on very tiny particles that we can't see with our eyes. Scientists use supergravity to help them understand things like dark matter and black holes, which are things that are really mysterious and hard to understand. Supergravity works by using incredibly powerful forces which pull together particles so they stay close together, making them easier to study and figure out.
