>The single electron goes through both slits.
How many times have you heard this? Look at vid related. This is how it's proposed the single electron goes through both slits. You see that portion of the wave reflecting backward? This generates a testable claim: if Copenhagen interpretation is the correct one, we should be able to put a screen behind the electron gun, and measure an interference pattern.
>But anon, the intensity would be too small!
Then put the gun closer to the slits. Also, I disagree. It will be small, but surely measurable over a very, very long time.

Can this Copenhatin shit finally be put to rest?

It doesn't go through both slits, according to the Copenhagen interpretation the electron is in a superposition and only the one that is observed goes through the slit.

I guarantee you I have more physics education than you do. You don't understand this post, so why don't you go post on some of the IQ threads or some shit? I'll spell it out in detail for the lurkers.

The double slit experiment reveals an interference pattern on a screen (the red screen here). >>14963214 and is one of the strongest pieces of evidence of wave-particle duality. Physicists (most notably Bohm, Einstein, Bohr, and Sommerfeld) attempted to explain (interpret) what they were seeing (more precisely: how the interference pattern arose). Quantum mechanically we know it has to arise from a probability distribution governed by the Schrodinger equation, but how exactly the electron passes through the slits was unclear.

The Copenhagen interpretation became the most popular interpretation (even until today, but is not the only interpretation out there). Copenhagen interpretation proposes the electron exists in a superposition of states (goes through one slit, the other slit, or both slits) all with finite probabilities. I claim if the Copenhagen interpretation is true, then a testable claim exists: there should exist a SECOND interference pattern on the blue screen here >>14963214 (and it is THIS experiment no physicist has ever done---Rutherford scattering is completely irrelevant).

It amazes me that undergraduates like to call others schizos. I guarantee you that you would fail my modern physics class.

This won't suprise. When x-ray EM waves scatter from crystal they make similar FFT diffraction image of the actual crystal.

Yes it does, and it's correct. There is a chance the electron can be reflected. Some times when an electron is emitted it doesn't go through the experiment. But so what? That It doesn't invalidate the double-slit experiment in any way.

What matters is if there's reflection of the wavefront backwards towards the direction the beam came from. This would disprove certain elements of Copenhagen and suggest light is much more of a wave-like form and that the supposed trouble is easily explained by existing theories of electromagnetism.

>> No.14964424

No it wouldn't. The whole point of the double slit experiment is where the particles that go through the slits hit the detector at the back. It's irrelevant if some are reflected.

The Copenhagen interpretation works. Because there is effects of particle and waves simultaneously.
The detector being on instantly collapses the wave functionality, and the particle keeps going. That’s proven.
Where the particle hits over time depends on wave function, observer, and randomness.

The slit is splitting the wave up. The particle goes through either slit.

That’s all that’s happening. The observer is messing with the setup. The math is working.

When they present this experiment they do it to blow minds. It’s not magic.

I’m not educated enough, I can’t remember if this happens faster than speed of light.

>> No.14970762

The interpretation has little to do with whether you would measure a backscattered interference pattern. All interpretations of QM make the same predictions for a simple case like this. It has nothing to do with muh Copenhagen. You absolutely could measure the backscattered electrons, and physicists routinely do experiments which include measurements of backscattered electrons and other particles. I'm not sure if the kind of experiment presented in the OP has been done in that form, or how technically challenging it would be. Unfortunately, few physicists are interested in such simple/fundamental experiments as they are unlikely to lead to anything other than a confirmation of basic physics and a very low-impact publication. Nonetheless QM is routinely employed in experiments involving backscattering, and the interpretation is largely irrelevant because all the valid interpretations make the same predictions except in some very tricky/special cases, which are at the edge of experimental viability.
