Gravitoelectromagnetism

Gravitoelectromagnetism is a mix of gravity and electricity. Gravity makes things that are close to each other pull together and electricity makes things that are close to each other push each other away. Together, gravitoelectromagnetism explains why things in the universe move the way they do. It explains why the planets around the Sun stay in their orbits and why some stars have planets around them. It also explains why the Moon and other planets spin the way they do.
