What do you think would happen if we broke the speed of light in a vacuum?

Let’s get a hypothesis thread going.

I think that if something like that did happen it would make the person see only the current state of everything from then until they slowed down. Like how if you see something go into an envent horizon on a black hole, it appears to just be standing still yet it’s actually getting work done all over it on crazy levels.

Does that make any sense?
