Eva Miranda and Isaac Ramos proved that a point particle bouncing inside a two-dimensional table with fixed walls can simulate a universal Turing machine, resolving a question left open by Cristopher Moore in 1990. This result shows that undecidability, like chaos, obstructs long-term prediction in classical mechanics, with reachability and periodicity becoming algorithmically undecidable problems.
