What does this experiments even prove? That everything is like in video games and only exist if you're looking at it?
I also saw a variation of this experiment where they split the photon and it would somehow still do the same thing even if the detectors were set much further away than the wall. Implying the light would send information from the future?

Seriously what does all of this mean for us? Simulation, stuff is predetermined, universe has a consciousness?

>explain to us the Delayed choice experiment
By polarizing a part of a photon wave, you change the properties of this part and prevent it from interacting properly with other parts. When you change parts of this wave again, to make them identical to each other, they regain the ability to interact properly.

since this is the qm thread can you guys help me understand something?
since neither the delta x or delta p can't be zero does that mean that two particles approaching each other will have momentum in every direction with every magnitude as x reaches zero? is that the same thing as degeneracy pressure and the explanation to why physicists say it's impossible for two things to touch?

It's part of degeneracy pressure; you also need the particles to be fermions or else they could all just assume the same state, and if it was one with low, not very uncertain momentum and high position uncertainty, you wouldn't get much pressure at all.

Quoted By:

>>14344278
Stars turn into black holes when the gravity is stronger than the degeneracy pressure. As a star collapses into a black hole, the uncertainty of its particles' momentum becomes larger and larger, increasing the degeneracy pressure, but the gravity also gets stronger as the particles move closer together.

>>Of course the introduction of the observer must not be misunderstood to imply that some kind of subjective features are to be brought into the description of nature. The observer has, rather, only the function of registering decisions, i.e., processes in space and time, and it does not matter whether the observer is an apparatus or a human being; but the registration, i.e., the transition from the "possible" to the "actual," is absolutely necessary here and cannot be omitted from the interpretation of quantum theory
this doesn't change the fact that wave function collapse requires the state data to register in the observers mind, and that is what Heisenberg believed. nice non sequitur, retard.

what if entanglement denotes a certain relationship to time

if time is a cone of possibilities in front of every object in the time axis couldnt entanglement be a 'unity' of all the particles into a single time universe?

since they are in the same universe once we describe that particular universe we can conclude information about both particles simultaneously

What I don't understand is how you can ever not observe it? Isn't the only way to measure something to make some sort of observation? at which point it collapses, so how can you ever confirm that there is a non-observable state?

If the particles are entangled, there are no separate wavefunctions of one particle or the other. There is only a combined wavefunction. That's what it means to be entangled.

Here is something that will really blow your mind about quantum entanglement.
You already know that two entangles particles act together even across huge distances "Spooky action at a distance" (the distance between them seems to be irrelevant, as if there was no distance between them).
Quantum entangled particles are entangled in space-time.
You can do experiments where the entangled particles act together across TIME, (spooky action through time, they act as if there was no time difference between them).

makes it seem like our time isn't the real Time, but is just the simulated sequence of events. same with space. the real Time/Space is outside the simulation and no spooky action is possible in the real thing.
If our universe has weird complicated physics, then Occam's razor supports the claim that our universe isn't the fundamental layer of physics.

Technically they do in order to perform any scientific experiment and share the findings. It always ultimately reaches consciousness if you look at the data as a human being.

it is in fact turned on by a conscious decision

reality does not "observe" reality for the sake of proving something to the same reality, that would be the observer, and that would change the game

You're right that they have a fixation on Hell, but it's precisely because they hate the idea of it and are genuinely afraid of the Demiurge sending them to Hell. If a LessWronger became God, he'd turn everything into a stereotypical utopia where nobody had free will and everyone was obligated to be happy forever.

So what I did at university in my physics course was just a dream? And the experiment, where we calcualted the loschmidt constant in our chemistry lab using a ruler, milimetre paper and a laser pointer with known wavelength, which builds on the same scattering principle, was probably just a hoax? No wonder my calcualtions where outside the error.
