Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. Aside from our sun, the dots of light we see in ...

As the system loses angular momentum, the orbit of the neutron stars tightens, meaning that the neutron stars move closer to each other.

Otherwise, the gas would consistently orbit the star and never fall onto it. Astrophysicists call this process "losing angular momentum," but how exactly that happens has proved elusive.

Dark matter also experiences angular momentum. It's another reason everything in space is moving. In the end, motion is a fundamental ingredient in the universe.
