To observe something on the QM level, you (pretty much) have to have an interaction of some sort. Light has to bounce off the thing, the thing has to hit something, etc. That's what collapses the wave function, the interaction.

Why does it do that? I don't fucking know, I guess interactions have to happen with definite values for some observables or someshit like that.

""Wave functions"" [math]\Psi(\vec{x})[/math] are essentially meaningless; what really matters is normalized probability distribution [math]|\Psi(\vec{x})|^2[/math]. From this, it is evident that an observation of a given quantum mechanical event simply returns a value within the domain of the wave function, just as rolling a pair of dice returns a value within the domain of possible results.

Not a science guy of any kind, but I thought light particles were enough to collapse it. It doesn't collapses because you're in the room, it collapses because you throw light at it in order to observe/measure it.

Contrary to the standard model, space is NOT empty, therefore waves propagate through a medium. EM waves are made of subatomic particles similar to how our oceans are made of H2O but at a much smaller scale. A wave will collapse only when an external force acts upon it. The observer is not just observing. A sub-atomic plasma medium will self-propagate waves due to the inherent kinetic energy.

>you will die not knowing exactly what an observer even is.

truth is you can not have a fundamental theory of physics that has magical objects,called observers, that don't obey the laws of your theory. If observers are made up of quantum mechanical particals, that are governed by the deterministic wave equation then the observer and the quantum system he observes just form an even bigger quantum System that evolves perfectly determenistic.

But then where do the propabilities he measures even come from?

It doesn't need to be observed by a human, to be "observed" is to crash into something else. Whether or not something really is there when you're looking is metaphysics and thus completely meaningless to talk about.

because there is a size limit to how small a particle can be (in 6 dimensions (3 spacial, 3 momentum))

it can be very small but must have a a very large momentum, or the other way round. It's not that you observe the particle and you figure out its position, it literally didn't have a definite position and occupied a large space. When you fire a photon at it you push it further into momentum dimension space and so it occupies less of the 'normal space'

in black holes, gravity gives the particles enough momentum and they all get pushed into momentum space when a star collapses

OP, even a brainlet can realise you're dumb as a rock.

Observation of particles is not passive. It's not the act of directing eyes/cameras at the particle that collapses the wave function.

It's the bombardment with other particles. They're needed to actually find the particle of interest, but upon the act of colliding them, they are modified (their wave collapses).

Think of a submerged submarine using sonar to find another submarine. It's active observation, and that activity creates interference in the original system.

Get it?

>> No.9830153

>>9827091
It's just probability. Before you observe an object you have (almost) no interactions with it so the probability distributions for your state and the state of the object are uncoupled, and all you're working with is the marginal distribution (p(object|you) = p(object)), but once you interact with it the distributions for the object and you will not be independent and p(object|you) will differ from and have less entropy than p(object). So you collapse the configurations of the object to just those compatible with your current state by collapsing the space of outcomes to those containing your current state, and may theoretically reverse the collapse by averaging over all the possible configurations you may take,.

Maybe someone can answer me on this:
Quantum particles seem to exist in a wave-form (i.e., their properties are probabilistic and undecided), only when they aren't interacting with something, correct?
Does this not seem like good evidence for a "simulated" universe? Computationally it would make sense to "cull" some data by not actually keeping up with each property of each particle when it has no bearing on anything else. So properties are assigned to particles only when convenient, and with only enough accuracy to keep the simulation from dissolving into chaos.

Is this a stupid idea? Has someone with credibility discussed this before?

Not accurate - in your example, the split coin you carry away is DECIDEDLY heads or tails, regardless of whether its been observed. In the quantum world, it is UNDECIDED if its heads or tails until you observe it. Therefore, observing it causes it to settle on heads or tails, and simultaneously the other coin decides it is the other option.
