Once one eliminates Platonism and accepts that mathematics is programming <https://codicalist.wordpress.com/2019/08/22/arche-programming/> then all of physics (what humans have thought of to model the cosmos) can be found in the numerical relativity and quantum simulation programs running on computers. So a program and a "physical structure" are only isomorphic if the universe itself is a simulation. @philipthrift -- You received this message because you are subscribed to the Google Groups "Everything List" group.
