You also assumed that chaos is a measurement problem. 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'll need an accuracy less of Planck length or else some systems are fundamentally unpredictable.

- dekhn 3y agoI'd love to see convincing evidence that we could simulate the universe using only standard physical laws. IIUC we don't have a way to do that or reliably say whether it's possible. It's also not that interesting a problem because it's so impractical.
- actionfromafar 3y agoBut it would be interesting to see if we could simulate a universe and observe if it in any way resembled ours. Even if the simulated universe was much "smaller". (It would of course have to be.)
- dekhn 3y agoI think you'd need to be a few rungs up the Kardashev scale to even contemplate this.
- actionfromafar 3y agoThat may be ... plus we don't really know what to make of the observations around us, with dark matter and stuff.
