Their findings, published in the Journal of Holography Applications in Physics, go beyond simply suggesting that we're not living in a simulated world like The Matrix. They prove something far more profound: the universe is built on a type of understanding that exists beyond the reach of any algorithm.

But if our universe does non-computable things, then CHURCH TURING IS WRONG, and we can build more powerful computers

Not necessarily. We could be in a simulation in a computer that can only exist in a universe with different physical laws

[โ€“] Artisian@lemmy.world 5 points 1 month ago

They specifically claim to refute the 'simulations all the way down' anthropic-flavored argument which goes as follows:

  1. We can make pretty good simulations already

  2. Later we'll want to make more and more detailed

  3. Therefore most folks that exist are inside simulations

  4. Ergo we're probably in a simulation

If our universe allows us to build more powerful computers, then this argument goes through just the same as it did with Church-Turing.

(I agree with your broader point: every thing our universe does is a new requirement on the universe simulating ours. But I don't think this is a particularly relevant observation for the 'are we in a simulation' question? Anything our universe does is tautologically something a universe can do.)
