I don’t think that we’re in a simulation, but I do find myself occasionally entertaining the idea of it.

I think it would be kinda funny, because I have seen so much ridiculous shit in my life, that the idea that all those ridiculous things were simulated inside a computer or that maybe an external player did those things that I witnessed, is just too weird and funny at the same time lol.

Also, I play Civilizations VI and I occasionally wonder ‘What if those settlers / soldiers / units / whatever are actually conscious. What if those lines of code actually think that they’re alive?’. In that case, they are in a simulation. The same could apply to other life simulators, such as the Sims 4.

Idk, what does Lemmy think about it?

  • It is incredibly unlikely.

    I know, “if an ancestor simulation is possible than it is much more likely you’re in one than not in one.” That’s fallacious, unfalsifiable and everyone loves to leave out the word “ancestor” which is very important to the thought experiment.

    In our universe, no system is entirely isolated from the rest of it. It is impossible to create a system that does not in some way interact with the outside universe. So if it is a simulation in a universe, and the universe it is running in also has this rule we would see information from that universe leak into ours in some way. How that would appear we don’t know, but it would be possible to figure it out. Maybe heat dissipates out, maybe bit flips happen in our universe due to the parent’s equivalent to cosmic rays, maybe the speed of light is a result of the clock speed of the simulator. We don’t know what it would be, but there would be something, and it would be theoretically discernible.

    at least some of the laws of our universe are laws of the parent universe. So maybe that rule, no system exists in isolation, is also true above. Or maybe our speed of light is the same for them. Whatever it is, our cumulative constraints are more than that of the simulation.

    All that, unless, in the parent universe, 1) systems can exist in isolation, or 2) it is an environment with no constraints. These two are functionally equivalent, so I’ll talk about them like they’re the same thing. In such a universe, there would be no causality, no form, nothing that makes it unified. It’s not a universe at all. It’s something like a universe post heat death. In such a scenario, running a simulation isn’t possible. If it were, to create an environment in which causality can be simulated, that environment wouldn’t be a simulation, it would be a bona fide universe.

    So I think, the fact that we see no evidence that we are in a simulation means we are probably not in one. So that means, if we are in one it is falsifiable and we can prove or disprove it empirically. And it also means we can escape, or at the very least destroy it.

    • There is no requirement for a subset of something to have the same properties as the superset. Just because everything in our universe is interconnected is no guarantee that the same applies to the hypothetical universe in which our simulation is run. This is ignoring that the idea is that we can’t see out of the simulation, i.e., there is no uncontrolled information being inserted into the simulation. This doesn’t preclude static from the outside impacting us in some measurable way…such as a background level of noise that is pervasive in the simulation, like the CMB.

      I don’t know if we’re in a simulation, but a lot of people smarter than me and more knowledgeable in the field have come to the conclusion that this idea isn’t falsifiable, and I doubt your proposal is a new idea for them. This leads me to believe they probably had a good reason to dismiss it, better than my points listed above.

        • Okay, but you’re glossing over the point, so let’s talk about black holes. They are part of our universe, information can go in past the event horizon, but no information can come out past the event horizon. Are they connected? Yes, absolutely. Can we collect any information from them, beyond a few basic physical measurements (gravity, momentum, rotation, mass-energy)? No, that whole event horizon again. So are you proposing that causality doesn’t exist in black holes, doesn’t exist in our universe, or that maybe we can have an interconnected system with a one-way transfer of information?

          Again, I’m sure someone with a PhD could not only come up with better reasons for the flaw in your assessment, but has probably already articulated it somewhere. Perhaps you should search that up.

          • Information comes out of black holes. That’s the whole point of the Hawking radiation thing. And information enters, obviously. Also those few basic measurements are information. Black holes are falsifiable and detectable.

            Causality inside black holes is not like causality out here, but it does exist. Once you enter, there’s only one direction you can go, no matter what you do. The outcome of everything was decided the moment you touched the event horizon. That outcome is that you will eventually evaporate as hawking radiation.

            I’m not glossing over the point. I’ve already addressed the crux of it. An environment in which systems can be totally isolated cannot function in any conceivable way as a universe. Everything inside would not be able to interact at all. It would be more like a substrate on which universes exist, if an environment can be isolated that does not allow for anything inside it to be 100% isolated.

                • Well, after doing some reading, you may be right. I didn’t hear about the issues brought up, and Hawkings responses in 2004. It seems the consensus is that information is conveyed somehow, with some limits on practicality. That may still raise issues with determining whether you’re in a simulation, if the capability to determine if you are is beyond the reach of your technology. At that point though, the only way you can falsify the hypothesis is to increase your capabilities to the point where you can test that, and I don’t think we’re there now.

                  • If we aren’t there yet, no point in believing it’s true. It’s like believing in god because we don’t have the technology to prove or disprove god. We can’t believe something that’s not currently falsifiable, we have to disbelieve it until we see evidence of it. I don’t think we are in a simulation.

                    I do think though that if it were true it could be detected with current capability, just that, if it is true, nobody has drawn the conclusion and investigated it yet. And information leaking in or out could be anything. The expansion rate increase of the universe could be energy leaking into the simulation. The speed of light could be a hard limit in the outside environment or something like a “clock speed” of the machine the simulation is running on. A slowly changing constant of nature, it could be anything. If it is true, there are indicators we are probably detecting, it’s just that we haven’t figured out what they’re indicating.

    • You presuppose that all the people in the world and scientists are actually people too. Sure the laws of the universe seem to be consistent in a Newtonian fashion as far as yourself have bothered to check. I don’t think you’ve done much personal quantum mechanics.

      The problem is more Cartesian, in the first place, maybe Trumanian. The others might be bad faith actors. Are you able to trust your senses, if so the other people?
