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.
Information that we are in one would appear in weird ways? Like maybe side effects of simulating a continuous universe in a calculable way which would require quantization, but would leave the universe with a seemingly incompatible framework of continuous macro behavior (such as general relativity) and discrete behavior (such as quantum mechanics)?
Yeah, the apparent effect to us could be something really weird like incongruent physical laws or constants or things like that. I have no idea what it would be, only that it would be detectable.
Like sync errors?
Sure, but I don’t think that’s what’s going on there.
I think observation/measurement of a quantum system means entangling with the system, so the quantum system becomes larger and includes the observer. Combine that with relativity, which is absolute in the universe, and you have an e plantation for that phenomenon.
That wouldn’t explain why the two results end up not agreeing sometimes.
I agree that it relates to how the observer entangles with the system, but you see this kind of error class occurring in net code all the time.
Player 1 shoots an enemy around the same time as player 2. Player 1 has a locally rendered resolution to the outcome of having killed the enemy and gets awarded the xp, and player 2 has the same result.
The server has to decide if it is going to let both local clients be correct or resolve in a way that reverses the outcome for one of the clients. For things that don’t really matter, it lets both be correct.
Here, each individual outcome is basically Bell’s paradox, where we know there needs to be consistent results no matter how each observer behaves. But in this case, when a second layer of abstraction is added, the results are capable of disagreeing.
It looks very similar to a sync error, and relativity doesn’t in any way explain it.
Why doesn’t relativity explain it? It looks like a classic case of relativity to me, what am I missing?
Relativity only relates to the relative shape of spacetime and movement through it.
So for example, things occurring faster for one inertial frame vs another, or something being closer to an observer moving quickly than for one stationary.
It’s exclusive to the combination of spacetime curvature and one’s momentum within it.
How do you think relativity does explain it?
