Stephen Wolfram and Nobel Prize winner Gerard & # 39; t Hooft both think that the universe is a cellular automaton.
As far as I know, & # 39; t Hooft has developed a series of frameworks to build different models of cellular automata and Wolfram has also proposed a framework in which network nodes could produce different universes of cellular automata.
Both have proposed specific models of cellular automata to describe our universe (or rather they work in a description of cellular automata that can fully apply to our universe), but as they proposed a framework to create different models of cellular automata, therefore think that these authors think that each type of cellular automaton corresponds literally to a universe.
For example, apparently, Stephen Wolfram, in his book "A New Kind of Science," in Chapter 9, defines a series of network nodes that can replicate all models of cellular automata. But I'm not sure of that and I would need someone who knows this area better to confirm it to me.
So, does anyone here know that it's okay? Does anyone here know if it works well enough to tell me if these physicists think that every model of cellular automaton corresponds to a universe?
