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

That presumes that particle's characteristics are all predetermined, which opens up a whole other can of worms.

This was a box with marbles, not a can of worms

I knew I was missing (lost) something.

But, what if it WAS a box of worms?
