Strictly speaking, nothing should exist in vacuum but the background radiation is present throughout the universe at a temperature of about 5 degrees Kelvin. And scientists are speculating about the existence of dark matter and dark energy. So, there may not be a real vacuum anywhere in the universe! But for all practical purposes, a vacuum is empty.

All force fields can exist in a vacuum - electromagnetic, gravitational, strong and weak nuclear. If there turns out to be such a thing as dark matter, then whether dark matter could exist in a vacuum depends simply on your definition of a vacuum. We could choose to define it either way.

Light exists within a vaccum. Dark matter may exist within a vaccum. Other than that, not much.
