Yep. There's a theory out now that says we live inside of a computer. That is, the universe is an information processing machine with ruthless precision. For example, if you want to find out where a thrown ball will land, you can sit at a desk, run Netwon's equations, and plot the trajectory. Or you can simply throw the ball. The universe provides the answer, perfectly every time.

I consider this theory basically moot. We know the universe conforms to our mathematical approximations. We know it's reliable. We know nothing is going to change this situation barring some fantastical event. We know that, however imprecise, we can communicate with the universe through math.

But there is a theory that goes further, which says that mathematics is the sole requisite for an object to exist. That is, if an object can be described by mathematics, then it does exist, period. I'm not sure what to make of this. I know that math is a human invention. I know that math will always fail, subtley, in comparison to the infinite complexity before us.

And yet, what are we but empty space? Mass is just vibrations held in place by forces, whatever those are. Atoms, mostly empty space, with tiny protons and electrons inside.

I used to say that mathematics was the language of God. I wouldn't go that far anymore. But I think he likes what we're thinking.
