Most people look at the universe and they posit order.

Look at all these patterns!

Someone must've come up with it all!

There's another tactic:
Posit randomness.

How does that work, you ask?

Well, randomness explores. What it can find includes patterns.

The universe is not all causal, but some of it is. Full randomness can be causal or not.

We're in a region of causality. Randomly.

Simple patterns you see a lot? You see them a lot because they're simple, not because someone put them there.

Take spirals. Take parabolas. The math is incredibly simple. A random walk through math space would produce these simplicities often by chance.

The universe is gorgeously patterned because simple, striking patterns are easy to produce computationally, and easy to stumble on randomly.

It is not order that someone created these patterns. They are the encrustations of randomness in mathematics, in causality.

This is not an original idea. It's a theory I read about. I've forgotten the name, but I believe the mathematician Kolmogorov either came up with it or was associated with it. And as always/usual, the above is my impression - maybe the flavor of the idea, or a plausible flavor - rather than the technical idea itself in any detail.
