    This paper is shit.

    https://jhap.du.ac.ir/article_488_8e072972f66d1fb748b47244c4813c86.pdf

    They proved absolutely nothing.

    For instance, they treat physics as a formal axiomatic system, which is fine for a human model of the physical world, but not for the physical world itself.

    You can’t say something is “unprovable” and make a logical leap to saying it is “physically undecidable.” Gödel-incompleteness produces unprovable sentences inside a formal system, it doesn’t imply that physical observables correspond to those sentences.

    I could go on but the paper is 12 short pages of non-sequiturs and logical leaps, with references to invoke formality, it’s a joke that an article like this is being passed around and taken as reality.

      I mean, simulation theory is kind of a joke itself. It’s a fun thought experiment, but ultimately it’s just solipsism repackaged.

      In reality there’s no more evidence for it than there is for you being a butterfly dreaming it’s a man. And it seems to me that the only reason people take it at all seriously in the modern age is because Elon Musk said he believed it back when he had a good enough PR team that people thought he was worth listening to.

        Simulation theory is actually an inevitability. Look up ancestor simulators for a brief on why.

        Eventually when civilization reaches a certain computationally threshold it will be possible to simulate an entire planet. The inputs and outputs within the computational space will be known with some minor infinite unknowns that are trivial to compensate for given a higher infinite.

        Either we are already in one or we will inevitably create one in the future.

          There’s a few wild leaps in logic, here.

          Firstly, we know of life evolving once. Just one planet. In the entire universe. We can postulate that with such a vast universe (and possibly multiverse) that it’s probable that other life exists elsewhere, but we don’t know that. It could be a unique event or an incredibly rare event. We can’t say, because 1 is way too small a sample size to extrapolate from.

          But you’re not even extrapolating from 1 datapoint. You’re extrapolating from something that you think might be true at some point in the future.

            I am skipping steps because this topic demands thought, research, and exploration, but ultimately the conclusion is, in my view, inevitable.

            We are already building advanced simulators. Video games grow in realism and complexity. With realtime generative AI, these games will become increasingly indistinguishable to a mind. There are already countless humans simultaneously building the thing.

            And actually, the lack of evidence of extra-terrestrial life is support of the idea. Once a civilization grows large enough, they may simply build Dyson sphere scale computation devices, Matrioshka brains. Made efficient, they would emit little to no EM radiation and appear as dark gravitational anomalies. With that device, what reason would beings have to endanger themselves in the universe?

            But I agree, the hard evidence isn’t there. So I propose human society band together and build interstellar ships to search for the evidence.

                The logic is not faulty, it is predicated upon conditional statements. It is actually a synthesis of Bostrom’s trilemma, Zuse/Fredkin digital ontology, Dyson/Fermi cosmological reasoning, and extrapolation from current computational capabilities.

                The “holes” are epistemic, not logical.

                  Okay, if you prefer to frame the flaws in your reasoning like that, then I’m happy to do so. That doesn’t make the conclusion less flawed. The conversation isn’t about the hows and whyfores of formal logic, it’s about whether the conclusion is likely to be true.

        Have you bothered looking for evidence?

        What makes you so sure that there’s no evidence for it?

        For example, a common trope we see in the simulated worlds we create are Easter eggs. Are you sure nothing like that exists in our own universe?

          If we’re in a simulation then we’d have no idea what’s outside that simulation, so we’d have no idea what an easter egg would look like.

          But it’s not my job to find evidence to prove other people’s claims. It’s their job to provide evidence for those claims. That’s true regardless of whether the claim is that we live in a simulation, that we’re ruled over by a benevolent omnipotent god, or whether there’s a teapot orbiting between Mars and the sun.

      You don’t even need to reject the applicability of Gödel, because there’s no proof that our universe doesn’t include a bunch of undecidable things tucked away in the margins. Jupiter could be filled with complete nonsense for all we know.

    “Robot, parse this statement, ‘this sentence is false’.” The robot explodes because it cannot understand a logical contradiction.

    I swear, that’s what this argument sounds like to me. Also, I’m genuinely confused why people don’t think that, if we can simulate randomness with computers in our world with pseudo random number generators, why a higher reality wouldn’t be able to simulate what we view as true randomness with a pseudo random number generator or some other device we cannot even begin to comprehend.

    Either this paper is bullshit or they’re talking about some sort of very specific thing that all these articles are blowing out of proportion.

    I don’t believe we are in a simulation but I don’t believe this paper disproves it. Just like I don’t believe in god but I don’t believe the question “can god make a rock so big he can’t pick it up?” disproves god.

      When we dream we often believe it to be reality, despite that in retrospect we can identify clear contradictions with logic in those dreams.

      A Matrix-like simulation doesn’t have to be perfect. We are a bunch of dumb-dumbs who will suspend disbelief quite easily and dismiss those who claim to see a different truth as crazy.

    “If we assume X theorem is true, Y theorem is true, and lemma Z is true, then …”

    This is actually about our models and seeing their incompleteness in a new light, right? I don’t think starting from arbitrary axioms and then trying to build reality was about proving qualities about reality. Or am I wrong? Just seems like they’re using “simulated reality” as a way to talk about our models for reality. By constructing a “silly” argument about how we can’t possibly be in a matrix, they’re revealing just how much we’re still missing.

    Lol, because these guys imagine the outer universe in which ours is built has the same rules and limitations.

      They also identity the particular junction that seems the most likely to be an artifact of simulation if we’re in one.

      A game like No Man’s Sky generates billions of planets using procedural generation with a continuous seed function that gets converted into discrete voxels for tracking stateful interactions.

      The researchers are claiming that the complexity of where our universe’s seemingly continuous gravitational behaviors meet up with the behaviors of continuous probabilities converting to discrete values when being interacted with in stateful ways is incompatible with being simulated.

      But completely overlook that said complexity itself may be the byproduct of simulation, in line with independent emerging approaches in how we are simulating worlds.

      We are reasonably confident that mathematical limitations apply to both the inner and outer universe. However they don’t understand the mathematical limitations enough to understand how little they matter. Pi is pi everywhere - that doesn’t change anything.

      There are truths we can’t prove true - again it doesn’t say anything about all the other trues we can prove.

    It’s possible that the universe could be simulated by an advanced people with vastly superior technology.

    Hard solipsism has no answer and no bearing on our lives, so it’s best to not give it another thought.

      It’s possible yes, but the nice thing is that we know we are not merely talking about “advanced people with vastly superior technology” here. The proof implies that technology within our own universe would never be able to simulate our own universe, no matter how advanced or superior.

      So if our universe is a “simulation” at least it wouldn’t be an algorithmic one that fits our understanding. Indeed we still cannot rule out that our universe exists within another, but such a universe would need a higher order reality with truths that are fundamentally beyond our understanding. Sure, you could call it a “simulation” still, but if it doesn’t fit our understanding of a simulation it might as well be called “God” or “spirituality”, because the truth is, we wouldn’t understand a thing of it, and we might as well acknowledge that.

        But that sounds like disproving a scenario no one claimed to be the case: that everything we perceive is as substantial as we think it is and can be simulated at full scale in real time by our own universe.

        Part of the whole reason people think of simulation theory as worth bothering to contemplate is because they find quantum physics and relativity to be unsatisyingly “weird”. They like to think of how things break down at relativistic velocities and quantum scale as the sorts of ways a simulation would be limited if we tried, so they like to imagine a higher order universe that doesn’t have those pesky “weird” behaviors and we are only stuck with those due to simulation limits within this hypothetical higher order universe.

        Nothing about it is practical, but a lot of these science themed “why” exercises aren’t themselves practical or sciency.

          I’m not sure I agree with the “no one claimed” part, because I think the proof is specifically targeting the claim that it is more likely than not that we are living in a simulation due to the “ease of scaling” if simulated realities are a thing. Which I think is one of the core premises of simulation theory.

          In any case, I don’t think the reasoning only applied to “full scale” simulations. After all, let’s follow the thought experiment indeed and presume that quantum mechanics is indeed the result of some kind of “lazy evaluation” optimisation within a simulation. Unless you want to argue solipsism in addition to simulation theory, the simulation is still generating perceptions for every single conscious actor within the simulation, and the simulation therefore still needs to implement some kind of “theory of everything” to ensure all perceptions across actors are being generated consistently.

          And ultimately, we still end up with the requirement that there is some kind of “higher order” universe whose existence is fundamentally unknowable and beyond our understanding. Presuming that such a universe exists and manages our universe seems to me to be a masked belief in creationism and therefore God, while trying very hard to avoid such words.

          The irony is that the thought experiment started with “pesky weird behaviours” that we can’t explain. Making the assumption that our “parent universe” is somehow easier to explain is really just wishful thinking that’s as rational as wishing a God to be responsible for it all.

          I’ll be straight here: I’m a deist, I do think that given sufficient thought on these matters, we must ultimately admit there is a deity, a higher power that we cannot understand. We may as well call it God, because even though it’s not a religious idea of God, it is fundamentally beyond our capacity to understand. I just think simulation theory is a bit of a roundabout way to get there as there are easier ways to reach the same conclusion :)

            Broadly speaking, I’d say simulation theory is pretty much more akin to religion than science, since it’s not really testable. We can draw analogies based on what we see in our own works, but ultimately it’s not really evidence based, just ‘hey, it’s funny that things look like simulation artifacts…’

            There’s a couple of ways one may consider it distinct from a typical theology:

            • Generally theology fixates on a “divine” being or beings as superior entities that we may appeal to or somehow guess what they want of us and be rewarded for guessing correctly. Simulation theory would have the higher order beings likely being less elevated in status.
            • One could consider the possibility as shaping our behavior to the extent we come anywhere close to making a lower order universe. Theology doesn’t generally present the possibility that we could serve that role relative to another.

      Yes, just like Minecraft worlds are so antiquated given how they contain diamonds in deep layers that must have taken a billion years to form.

      What a simulated world contains as its local timescale doesn’t mean the actual non-local run time is the same.

    I was under the impression that something along these lines was already accepted from the perspective of information theory. I.e. a machine that could simulate the universe must at least be composed of as much information as the universe itself. Given the vastness and complexity of the universe, this would make it rather unlikely that the universe is simulated. Unless you want to view the universe itself as a machine that calculates it’s own progression. But that is a bit of a semantic point.

    Disclaimer: this is not my area of expertise and I probably got some terms or concepts wrong. I am basing this off of ‘The information’ by James Gleick
