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.
How do they conclude that any simulation would have to be (purely) algorithmic? (For a fictional counterexample, take Douglas Adams’ Total Perspective Vortex, which simulates a universe by extrapolating from a physical piece of cake.)
That’s exactly the sentence that made me pause. I could hook up an implementation of Conway’s Game of Life to a Geiger counter near a radioisotope that randomly flipped squares based on detection events, and I think I’d have a non-algorithmic simulated universe. And I doubt any observer in that universe would be able to construct a coherent theory about why some squares seemingly randomly flip using only their own observations; you’d need to understand the underlying mechanics of the universe’s implementation, how radioactive decay works for one, and those just wouldn’t be available in-universe, the concept itself is inaccessible.
Makes me question the editors if the abstract can get away with that kind of claim. I’ve never heard of the Journal of Holography Applications in Physics, maybe they’re just eager for splashy papers.
