Stephen Wolfram thinks the entire universe is built from simple rules

For the algorithm to work in many dimensions (XML tags), I feel like it must be a simple algorithm.

Rule 110 is known to be Turing-complete. https://en.wikipedia.org/wiki/Rule_110

I have a feeling that Rule 90 is the most efficient algorithm: the Sierpiński Triangle, self-sacrifice, infinite recursion to a perfect pattern. I'm not mathematically talented enough to prove that though.

Please come to chat about A New Kind of Science on Facebook! A couple of weeks ago I noticed that the page didn't exist, so created it. Hopefully Wolfram doesn't mind. We stand on the shoulders of giants.

I'm no physicist, but doesn't the Standard Model fit on a few pieces of paper? That the universe has rules that are a lot simpler than the behavior that emerges from those rules doesn't seem like novel claim. Wolfram's idea to examine the universe by exploring CA-space is the novel part I think.

With a lot of fuzziness, some state and temporal stuff.

Yea, the fuzziness comes from protons shuttling about, tunneling around, electrons moving in cycles with phosphates. It's all just vibrating, bumping and bumbling about. I remember how blown my mind was when I first learned that all reactions catalyzed by enzymes would have happened anyway given enough time and the enzymes just tune the systems to work in concert in a time frame conducive to life.
