UBC researchers claim the universe can’t be a simulation, citing math that proves reality goes beyond computation and algorithmic logic.

And here I was waiting to get unplugged, or maybe finding a Nokia phone that received a call.

    But who sait it must be a perfect match?

    I mean they can argue that we can’t simulate correctly the universe (just check kaos theory) but that doesn’t mean we cant simulate a universe. Even a universe that looks feels like ours.

      The paper makes the argument that the universe we live in is mathematically uncomputable. No algorithm can describe it. There’s no mathematical formula we can use to compute the universe as it is.

      If this is the case, then we don’t live inside a computer. Something more than pure computation is required.

      Now their argument is that quantum gravity is the thing that makes the universe uncomputable. I’m not sure how valid this part of their argument is.

        SO many assumptions in that statement

          Well, ”computer” in the mathematical sense is well defined of what it can and cannot do. The limit is the halting problem or equivalent problems.

          The question is: is there some equivalent to the halting problem in the real universe? If that’s the case, then there’s no algorithm you can use to describe the entire universe.
