Why/how is light the fastest thing in the universe and nothing else can be faster?

Why have we ruled out the possibility of finding something faster when we’ve only scratched the surface of space exploration and understanding?

Light isn’t the fastest thing. It is one of the fastest things. It moves at the speed that things go when nothing’s slowing them down at all. The real name for this speed is *celerity*.

Is it possible that something could somehow go faster? Yes, I suppose, but it really doesn’t seem like it. We don’t need to know what the composition of dirt on some distant planet is to figure out it’s almost certainly made of baryonic matter – the same elements that almost everything else we see is made of.

The rules of our universe seem pretty consistent about this sort of thing. We’re always happy to be surprised, but it’s not looking likely.
