It was reported previously [8] that the behavior of free electrons in superfluid helium has again forced the issue of the meaning of the wavefunction.

Electrons form bubbles in superfluid helium which reveal that the electron is real and that a physical interpretation of the wavefunction is necessary.

(electrons have a position that is definite and not spread across a continuum of values)

Furthermore, when irradiated with light of energy of about a 0.5 to several electron volts [37], the electrons carry current at different rates as if they
exist with different sizes.

It has been proposed that the behavior of free electrons in superfluid helium can be explained in terms of the electron breaking into pieces at superfluid helium temperatures [37].
Yet, the electron has proven to be indivisible even under particle accelerator collisions at 90 GeV (LEPII).

The nature of the wavefunction need to be addressed. It is time for the physical rather than the mathematical nature of the wavefunction to be determined.

So is this what they got you studying in your physics class?

Unless, of course, if two electrons interacting constitutes a "measurement" and the wavefunction collapses just from that. For example, the solution to the Schroedinger's Cat paradox is that the Geiger Counter detecting radiation (or not) constitutes the measurement which collapses the Cat's wavefunction.

Here's what David Griffiths concludes his Quantum Mechanics textbook with. I added the bold toward the end to emphasize what is probably the most relevant sentence, but really the whole thing is cool enough to be repeated.

In this book, I have tried to tell a consistent and coherent story: The wave function (Psi) represents the state of a particle (or system); particles do not in general possess specific dynamical properties (position, momentum, energy, angular momentum,etc.) until an act of measurement intervenes; the probability of getting a particular value in any given experiment is determined by the statistical interpretation of Psi; upon measurement the wave function collapses, so that the immediately repeated measurement is certain to yield the same result. There are other possible interpretations -- nonlocal hidden variable theories, the "many worlds" picture, "consistent histories," ensemble models, and others -- but I believe this one is conceptually the simplest, and certainly it is the one shared by most physicists today. It has stood the test of time, and emerged unscathed from every experimental challenge. But I cannot believe this is the end of the story; at the very least, we have much to learn about the nature of measurement and the mechanism of collapse. And it is entirely possible that future generations will look back, from the vantage point of a more sophisticated theory, and wonder how we could have been so gullible.

Point taken. So do you think that the electron bubbles in the superfliuid helium would mean a collapse of the wavefunction? Also, what do you think about there being a level below ground state for the electron in hydrogen? The man who wrote the OP claims that he has done this and replicated it in different labs.

Well, that electron bubble is proof that the electron has a definite position. I would guess that it means that the superfluid helium's interaction with the electron constitutes a measurement which collapses the electron's wavefunction, but I can't say for certain. That's my Bachelor's degree's opinion :P

Well this is the first I've heard of anything. Have a citation? I'd like to try to read up on it but I don't see anything from scholar.google.com. Must be some very new work? I'd be hesitant to accept it until it's been peer reviewed though, instead of just repeated by the same guy. It's possible it's a systematic error in his method or theory rather than a systematic error in his equipment.

Still though, below the ground state? Is he he detecting photon emissions corresponding to energies greater than ~13.6 eV? I don't really understand what it could mean for there to be something with a lower energy than the ground state. I'd say it meant the electron was captured by the nucleus, but that's already a known type of radioactive decay (and I think only happens in much heavier atoms, since electron + proton --> neutron + energy, so a hydrogen atom would just become a neutron).

Aetheric doesn't know anything.

His primary sources of information are wikipedia and some fringe internet theorist who promotes something called "aether wave theory" (whom as far as I know, knows just as little). He likes to believe it, like a religious person, because it's not in the mainstream and it's promoted in a manner which makes aetheric believe that he's "above" the hivemind of mainstream thought. Diagnosis: he's a religious person.

When I say he doesn't know anything, I mean he has no idea how any of these ideas fit into the bigger context or how they're supported scientifically and mathematically. He doesn't have a formal education, and he probably hasn't even bothered to read an introductory physics textbook.

So yeah, you're more likely than not arguing with a brick wall.

I don't accept the Aether Physics Model as it has too poor and too little empirical evidence supporting it. I do support what this thread is about, and the idea that there could be lower than the ground state for hydrogen. I don't have an education in physics yet, but I can still discuss it with other people, just like how most people on PaRD don't have an education in certain issues and they still discuss them.
