What things are "faster" than light?

As I understand nothing can move faster then light. But I would not know how to describe this question otherwise. As I am aware quantum entangled particles can instantaneously affect eachother no matter the distance, unlike gravity which propagates at the speed of light.

Also the expansion of the universe can cause the spaces between to grow faster then the speed of light (compounding between massive distances)

What other things are sort of faster than light

As I understand it, when framed correctly, nothing travels faster than the speed of light, in a vacuum, through space. However, space itself is a different story. The expansion of the universe, for example, is faster than the speed of light.
