Computer models are starting to "dream up" weird physics patterns that actually don't exist in the real world.

Effect of machine arithmetic errors for multi-turn invariant curve destruction
arXiv · 2603.16174
The Takeaway
Scientists found that standard computer hardware creates tiny rounding errors that manifest as intricate, 'ghost' structures in physics simulations. This means that some complex behaviors seen in digital models are actually just hardware glitches where the computer was unable to calculate with perfect precision.
From the abstract
Using the example of three-dimensional Mira map, it is shown that the destruction of a multi-turn invariant curve can occur through the appearance of local multiple bends. It was found that, depending on the precision of machine arithmetic, a complication of the multi-turn invariant curve can be observed, which is a numerical artifact. Artifact can be avoided with increasing of machine arithmetic accuracy.
