They also identity the particular junction that seems the most likely to be an artifact of simulation if we're in one.

A game like No Man's Sky generates billions of planets using procedural generation with a continuous seed function that gets converted into discrete voxels for tracking stateful interactions.

The researchers are claiming that the complexity of where our universe's seemingly continuous gravitational behaviors meet up with the behaviors of continuous probabilities converting to discrete values when being interacted with in stateful ways is incompatible with being simulated.

But completely overlook that said complexity itself may be the byproduct of simulation, in line with independent emerging approaches in how we are simulating worlds.

We are reasonably confident that mathematical limitations apply to both the inner and outer universe. However they don't understand the mathematical limitations enough to understand how little they matter. Pi is pi everywhere - that doesn't change anything.

There are truths we can't prove true - again it doesn't say anything about all the other trues we can prove.
