You could simulate entire universe if you knew the initial conditions sufficiently enough. There were two nice recent papers[1][2] that showed in order to predict some orbits you&#x27;ll need an accuracy less of Planck length or else some systems are fundamentally unpredictable.

What they do is to increase the accuracy so much that physical perturbations at the quantum level dominate, not numerical accuracy. Irreversible up to the Planck length means fundamentally unpredictable. https://arxiv.org/abs/2002.04029</p><p><a href="https://hackerpaper.kaipfister.de/p/2002.04029/">Paper and discussion history</a>.
