It would seem to me as a layman (I have a degree in CS, but my grasp of theory was always tenuous), that discussing the ability to calculate an equation that models a physical system is different than the physical system itself. The universe doesn't need to "calculate" it's systems before it executes them, they just do what they do (for lack of a better description).
That said, this feels a bit like "A New Kind of Science," where Wolfram extrapolated from computational games to saying "this is how the universe works", which was a leap that few found very compelling.
- emacdona 12y agoThe question I came here to ask relates to your comment: > 'The universe doesn't need to "calculate" it's systems before it executes them, they just do what they do (for lack of a better description).' What I want to ask someone who knows a bit more about modern physics is this: is this article evidence that we do, in fact, live in a simulation?
- wyager 12y ago> The universe doesn't need to "calculate" it's systems before it executes them The universe "executing" is a calculation. The universe is isomorphic to a computer calculating the universe. > the ability to calculate an equation that models a physical system is different than the physical system itself This is a philosophical question. Arguably, the physical system is just that calculation being carried out.
