Something like Wolfram's vision has to be true if materialism has any hope of working. The universe is finite and discrete, so a Turing machine is an upper bound on its capabilities. The original thing that started it all has to be really simple: have a large(ish) probability of occurring by chance and a very high compression to get an orderly universe.
Therefore, if materialism is true, then in the beginning must be some simple, but potentially Turing complete substrate, such as a cellular automata or graph thingamabob.
- goatlover 6y ago> The universe is finite and discrete, Well, the universe appears to be close to flat, which would indicate an infinite size. And the discreteness of spacetime in QM hasn't been made to work with Relativity, thus the forays into String Theory and Quantum Loop Gravity.
- yters 6y agoEven if there is an infinite expanse, there are only finite effect ranges. Does anyone seriously think infinity has any sort of physical impact? I've never seen such an idea in all my years of physics exposure.
