Tegmark's Mathematical Universe Defeats Most Proofs Of God's Existence
It feels like 2010 again - the bloggers are debating the proofs for the existence of God. I found these much less interesting after learning about Max Tegmark’s mathematical universe hypothesis, and this doesn’t seem to have reached the Substack debate yet, so I’ll put it out there. Tegmark’s hypothesis says: all possible mathematical objects exist. Consider a mathematical object like a cellular automaton - a set of simple rules that creates complex behavior. The most famous is Conway’s Game of Life; the second most famous is the universe. After all, the universe is a starting condition (the Big Bang) and a set of simple rules determining how the starting condition evolves over time (the laws of physics). Some mathematical objects contain conscious observers. Conway’s Life might be like this: it’s Turing complete, so if a computer can be conscious then you can get consciousness in Life. If you built a supercomputer and had it run the version of Life with the conscious being, then you would be “simulating” the being, and bringing it into existence. There would be something it was like to be that being; it would have thoughts and experiences and so on. https://www.astralcodexten.com/p/tegmarks-mathematical-universe-defeats
