As an addendum to my last post I might mention that there has been a lot of philosophical discussion about why the universe seems to be mathematical. People who think deeply about this don't see any reason why the universe should be able to be described in mathematical terms. For example one of the primary descriptions in physics is F=MA. That is the force applied to an object is equal to the mass of the object multiplied by the acceleration of the object. This has been shown to be true, but philosophers don't see any good reason why it should be true.

So when we develop theories about the universe they all wind up being mathematical in nature. The best that most scientists can say to this is that that is the way it is. Philosophers of course want to know why things work, not just that they do.

C is the universal speed limit.
