Wolfram Physics Q&A

We believe we have found the class of rules, but (so far as we know) we have not yet found the specific rule. The phenomenon of computational irreducibility makes it difficult to determine the complete consequences of any given rule. However, a major finding of the project so far is that the core theories of current physics can be derived generically for models of the class we have identified, without needing to know the specific underlying rule. One of the more abstract findings of the project is that it is also the case that the specific rule to use to describe the universe depends on one’s language for description, and so with different description languages different rules will be considered The Rule.
