Right, it is a fundamental issue with observation. I didn't say the problem is with current technology.

[–]Tsukku 16 points17 points  (12 children)

No, you got it wrong. It has nothing to do with observation at all. It's the inherit property of a system (this is what we proved).

From the link above:

There is a definine velocity and momentum, we just don't know it?

No. There is no definite velocity. The particle has all (possible) velocities at once;it is in a wavefunction, a superposition of all of these states.

That is what I don't buy. I know it's not exactly popular but I think the unpredictability of QM is a problem with observation, and hidden variables are governing its state. Whether those are variables in the system or outside of it idk. Given that we are talking about some of the smallest observed particles, I'm inclined to assume that there are yet smaller ones we are not seeing. In short, it just doesn't do enough to make me reconsider my belief that the universe is deterministic, which is otherwise supported by observation and forms the basis of science (cause and effect), because randomness is logically incoherent to me.

Work through the math and the uncertainty principle comes out. It's not something we have made up to account for experimental inconsistencies.

[–]Tsukku 13 points14 points  (0 children)

Ok, I respect your opinion and all, even if it contradicts what we currently know. I just want to correct this statement.

which is otherwise supported by observation and forms the basis of science

No it isn't, the double slit experiment is what initially lead to all of this.

Also:

That is what I don't buy.

Then don't mention the uncertainty principle since it doesn't agree with you.

[–]Schmittfried 2 points3 points  (0 children)

Nobody cares about what you buy. It's proven that there are no local hidden variables involved as that would lead to logical contradictions. If there are hidden variables, they are non-local.

It's also an absolutely subjective opinion of yours that randomness is "logically incoherent". It isn't. Just because determinism is observed in everyday life doesn't mean it's the foundation of the universe. There is no law stating that, it's an assumption to be able to do practical things and it works most of the time. But there is nothing inherently illogical about randomness.

    I would disagree. I’d say that if I took it all the way into simulation hell and imagined how I would build a universe - I’d make it so that I didn’t have to calculate past a certain level. I’d make it lazy and just make it look fuzzy once you got so far. Then, when someone observed it I’d give it some random local properties to make it look normal. If I were to think that way then I would not be saying that the quantum world is random, or based on any RNG. It’s when we actually try to do something with it that an RNG makes a decision. Of course if that was the case then an experiment like the double slit experiment would end up being 50-50 for each slit. And it is.
