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.

    We simulate weather systems all the time, even though the systems are fundamentally chaotic and it’s impossible to forecast accurately.

    The amount of computer power used to run those simulations is immense, and even then, the predictive capacity of those models starts degrading rapidly around 7 to 10 days ahead. There’s some amazing science that goes into those models, but the results are hard-won. And what we know about more energetic systems (say, the magnetohydrodynamics of the sun) is far less comprehensive.

    And be careful with that “fundamentally chaotic” assertion: there are degrees of how chaotic a system is, and some aspects of a system can be more deterministic than others.
