[–] SmoothOperator@lemmy.world 1 point 11 months ago (1 child) I mean, if you take an existing physics simulation and just scale up the hardware... Then what? We have no reason to believe that would cause parts of the simulation to be conscious and think they exist in reality. permalink fedilink source parent hideshow 2 child comments replies: [–] CanadaPlus@lemmy.sdf.org 1 point 11 months ago* (1 child) We're physics. It seems like we exist. permalink fedilink source parent hideshow 2 child comments replies: [–] SmoothOperator@lemmy.world 1 point 11 months ago (1 child) But we have no evidence that we're anywhere close to being able to accurately simulate physics, even with planet sizes computers. permalink fedilink source parent hideshow 2 child comments replies: [–] CanadaPlus@lemmy.sdf.org 1 point 11 months ago* (last edited 11 months ago) (1 child) We can accurately simulate physics, outside of certain extreme environments. My evidence is that we routinely do, although hardware limitations mean if you want perfect accuracy it's going to involve just a few particles, with more and more approximation as you scale beyond that. There are no extreme environments on Earth, by that definition, which is a big part of why physics is stuck on them in the first place. All known life is also on Earth, so that shouldn't matter, if life and consciousness is what we're interested in. permalink fedilink source parent hideshow 2 child comments replies: [–] SmoothOperator@lemmy.world 1 point 11 months ago (1 child) We can accurately simulate physics, outside of certain extreme environments This is not true. For example, we don't know why [ice is slippery].(https://doi.org/10.1016/j.coldregions.2014.03.002). Furthermore There are no extreme environments on Earth... Yes, there is. Ice. And superconductors. And so on... And even if all the other stuff is exotic, it's important to know all the other underlying principles to comprehend what's actually going on. permalink fedilink source parent hideshow 2 child comments replies: [–] CanadaPlus@lemmy.sdf.org 1 point 11 months ago Yeah, that's more than a few particles. If you had a planet-sized computer, you could still simulate a block of ice, although it might still be hard to explain in a bird-eye view kind of way why the simulated ice is slippery. Which is what this paper is actually trying to do. Ditto for superconductors. It's true that closer to absolute zero something is, the longer quantum features stay relevant, and that imposes a pretty punishing penalty. It's not infinite, though. permalink fedilink source parent
