What you think of as the speed of light is really the speed limit of the universe and light is the only thing we know of that can go that fast. The theoretical ways to faster than the speed of light involve creating a bubble that compresses space around it and riding collapsed spacetime like a surfer. But the creation of the bubble and the removal of the bubble are both very likely impossible, but its hard to say for sure because we don’t even have a mechanism for how we could possible create one
