One thing that always amazes me is how much computational power it takes to simulate something as simple as a ball rolling through fur. Yet nature ‘just does it’—in an ‘instant’, whatever that meanspic.twitter.com/0ZUr1LWBn1

Reminds me of the quote by Laplace: ‘Nature laughs at the difficulties of integration’

But this is assuming your computer's time and your simulation's time are the same dimension. If you simulate slices of time from "the outside" of your universe, a person inside it would not feel your time, but the time difference you impose between the slices.

Yes. I don’t know how the universe does what it does

Gives some reason to believe that nature isn’t computing anything (like some think)

It's certainly doing *something*, as
@RyanDavidReece would put it. The question is what and how does it follow its own laws consistently. - 1 more reply

Haha yeah I think about that. Whatever is running our holouniverse isn't Intel

Nature always seems to "solve" differential equations with pretty much infinite precision. It's pretty weird once you start thinking about it. Shouldn't nature be bound by computational complexity?

But A) nature has(/is?) an absurdly massively parallel 'computing architecture', and B) what would it even imply for our experience if the universe did its computation somehow 'inefficiently' or 'slowly'?
