Ok, so you know how cars go very fast, right? But even the fastest cars can't go faster than the speed of light. That's because the speed of light is like a big rule in the universe, kind of like how you have rules at school or at home.
But some people have been wondering if there's a way to go faster than the speed of light. And scientists have been trying to figure it out for a very long time. Some of them think that there might be a way to do it by bending space and time, sort of like how you can fold a piece of paper to make it shorter.
But even if we did figure out a way to go faster than light, it's not like you can just jump in a spaceship and take off. There would be a lot of new rules and things we would have to figure out. So for now, we can't go faster than light, but maybe someday in the future we'll find a way!
