Why has the mainstream physics community ignored Pilot Wave Interpretation and other non-random quantum models? I feel like these models are the only way we're ever going to get actual scifi technology rather than just shinier iPhones.

What are the actual problems with Pilot Wave? Are Physicists just stuck in the Copenhagen paradigm?

It has been shown that any & all "hidden variables" theories are non-local.
This means that the pilot wave exists, independently of space and time. It sounds a bit like God with another name attached to it.
More importantly, how do I measure it ?

Probabilistic QM doesn't have to be really "true" at the subatomic level. It's just a formalism. What matters is that it gives predictions and results.
I am not familiar with the results predicted by the pilot wave, but Copenhagen Interpretation has never been disproved and the formalism is very powerful.

The point is, Copenhagen gives us a set of axioms and those axioms give us proper results.
I don't think we will be able to develop the tools and senses to understand the subatomic world and explain it. Our job should be to predict and measure it. Doesn't matter if our explanation isn't what is "truly" happening at the subatomic level.

I am a mathematician at heart, so for me, it's not really a problem. There are already plenty of unsolved; well-posed and interesting problems in "standard" QM and in the more esoteric QFT.
Maybe one day the QFT experiments will be able to show us the strings of String Theory and, maybe then, QM, QFT will all take the place Newtonian Mechanics have today, a powerful model that we used to investigate and formalise the world around us until we found an even better one.

Physics only progress when we have experimental data to put models on. If you can't confirm your theory, you're doing mathematics (which is fine.)

God didn’t play dice. The idea that the quantum world is “probability” based is heavily flawed. It’s the best we can do at this stage in our development as a species, but if we were a lot smarter we could even correctly measure photons and account for the intererence caused by our measurements as well, allowing us to know absolute positioning.

QFT is relativistic, it follows the laws of SR and works on curved spacetime.
The problem with GR is that it isnt quantum, thats different from saying that QFT isnt relativistic.

I can answer your question but you gotta work with me for a minute,
Let's start at the beginning.

In the OP diagram, which experiment are they referencing?
As in
-The name of the scientist that performed the experiment.
The name of the experiment (it's a twin slit experiment, but there were several, the first being "Young's twin slit experiment" etc, performed with light, not electrons)
-the date the experiment was performed.
-who peer reviewed it
-which journal published the paper etc.

Once we have the details of the experiment we can discuss the results ;)

Important questions are
-what did they use as a detector and how were the observations with an observer carried out.

Once we know this it all makes a lot more sense, so we need to know which experiment the diagram is referencing.

There's nothing wrong with randomness. It makes a lot of sense actually as what you'd find at the smallest most fundamental scales of reality since there are fewer and fewer ways in which a given outcome will be significantly different from any other outcome for a given set of starting conditions. Non-randomness is what builds up as you zoom out, a lot like how in the very short term poker can be random but as you watch more hands play out everything tends towards the predictable patterns players who know what they're doing base their strategies around.

>> No.11072105

>>11071661
As long as no one can answer the question "which experiment are these results from?"
I can explain them,
Quantum mechanics is a hoax in its entirety.
These results are deliberately misleading.
The experiment with electrons doesn't look like the experiment in OPs diagram,

When electrons were fired through the twin slits, the technology at the time wasn't able to make an electron gun that could fire individual electrons,
And please people, electrons are electronegative, the self repel and are attracted to anything with a different charge, so because of electrostatic build up in the slits, charging them with negative electrons, as the beam of electrons passed through the slits, the were being interfered with by other electrons and creating a random interference pattern ;)
It's not magic.
It's not quantum mechanics.
It's scientists on the cutting edge of technology misinterpreting results because they didn't understand what they were doing fully.

This experiment was basically a cathode ray oscilloscope,
And if you want proof do some research into the experiment timeline.
The "reciever" wasn't like in the diagram, it's was a convoluted contraption, each time they did the experiment they got different results.
The whole "active observer" thing was because the dynamic nature of the electron interference generated a random pattern.

>> No.11072210

>>11072105
And if you want to understand it a little more (and I know you got your arcane esoteric texts from almost two centuries ago ready to reference)
But
Young's twin slit experiment done with light = wave interference pattern
Twin slit with particles ie say you fired a machine gun through two slits = two distinct "shadows" of the slits, particle pattern.
Twin slit done with charged electrostatic particles like electrons = random pattern halfway between wave and particle because the electrons interact with each other.
Wave particle duality is a lie.

Do you guys wanna hear a story,
So theres this autist right and he decided when he wanted a Nobel prize.
So he did all the things the people that got Nobel prizes did, studied hard, read all the books, went to university etc, all the boring stuff.
And one day while he's in his Bitcoin mining phase and using PGP encryption on all his silk road transactions he reads this random book about cryptography and it had a chapter about how the United states government was trying to ban private encryption services but one day they developed a quantum computer that could crack encryption algorithms almost instantly, and that's why they stopped the ban legislation. So he's all like "I could just run a quantum computer and crack the sha256 Bitcoin algorithms and be able to print my own money"

Long story short, he tried to build a quantum computer, so after about 8 years of full time quantum computing research and development you wanna know what he discovered?

Quantum computing is a hoax.
It isn't real, it's like time machines or teleporters or warp drives.

But you know what else he discovered?

All quantum mechanics is a hoax.

One of them is broken right now, because an idiot brought chisels for maintenance while one of the QCs was running. They have to be cooled down to create an enormous magnetic field of almost 10 Tesla. That field ripped the metal part of the chisel out of the rubber coating and into the cryostate.

I know for certain that upper level PhD physicists know that quantum computing is a hoax. But who would lose their high paying job and elitist position over something so trivial.

PhDs in what?
The only valid criticism I've heard about is that QC may not be able to accelerate computations for practical problems the way it was promised. For example in finte element analysis, there was a scheme proposed that theoretically yields exponential speedup, but if you take into account you have to repeat the computation for a statistical significant result, you'll end up with "only" quadratic speedup.
The million dollars of a Nobel prize are tied to your research, btw. It's only used for new lab machinery or personnel.

Personally, im a theoretical physicist and only worked together with the people who built those QCs I talked about for my thesis. They look roughly like the one on the bottom of this page:

NMR spectrometer is needed to read out the qubit states. Saying NMR isn't quantum is just outright wrong.

The "may" in that article refers to the fact that classical computers were well capable of getting the prime factors of 21 at the time of publication, but wouldn't be able to factorize larger numbers in useful time. QCs may be able to do this is what they're saying. Of course, you're too deep into the conspiracy theory to see that. Still, they got Shor's algorithm to work on an NMR QC which is what disproves your claims, and you are the one changing the subject attacking strawmen arguments here. Practice what you preach.

THAT'S NOT HOW IT WORKS AND I'M SICK OF IT

"observer interacts" means introducing another source of interaction from photons, so it's not just electrons interacting with electrons anymore
it's not some magical spooky shit that needs to be explained by a new theory

It's as if a normal man was observing two pingpong players bounce balls for 10 minutes without flaws. The conclusion is they are two equally good players.
Then you introduce a blind man. The blind man takes is white blind man's tapping stick and he starts to swing it randomly over the table, hitting balls and players alike for another 10 minutes and your conclusion being, blind man doing the observing magically and spookily turned them into worse players.

"seeing" is eyes detecting photons scattered off of things, just like the blind man is bouncing his walking stick stick off of things.
in order to see the slit, you need to shine light there, just like the blind man needs to wave around his stick.
electrons and photons can interact with each other, just like the blind man's stick and pingpong ball.
that's what the "observation changes the outcomes" means
