I think quantum entanglement is a joke based upon the misunderstanding of how simple reality really is and how it works. First Bell's theorem has a number of unspoken assumptions. One of which is that it assumes there is no aether. Here is the logic which accordingly explains what I think is the folly with quantum theory.

Take two particles such as electrons. Bring them very close together and they will become entangled. This is straight forward and simply based upon the meaning of the word entanglement. In this case we can talk about the simplest entangled characteristic such as spin up and spin down. So all might agree that the two electrons have become entangled. Why this entanglement takes place is a mystery is quantum theory. In aether theory it's elementary. Each particle produces a surrounding vortex which influences the other particle causing it to take a complementary characteristic to enable their coexistence at such close quarters, such as one having spin up and the other spin down.

Next QM makes another assumption. It assumes that in this entangled state, or any state for that matter, that these particles have no definite state unless they are observed. This is based upon the Copenhagen interpretation, having no observational basis that I know of. This was the basis for the joke/ ridicule by Shroedinger concerning his half alive and half dead cat.

If instead the states are always in a determined state then again the entanglement idea is a joke. Again take two electrons bring them close together and they will accordingly become entangled, necessarily according to aether theory. According to the theory of determinacy their states are generally determined and definite, therefore one electron has spin up and the other spin down immediately upon entanglement. Send them off in two different directions and after a hundred miles all are amazed that if one is detected to have spin up, the other will have spin down, just like QM predicts. I don't think it even would make a good magic trick since most of the observers would not be so gullible concerning the idea of so-called communications between the electrons. Amazing, or not? To me "or not" is logical and simple for almost anyone to understand, but the "amazing" explanation totally lacks any possible logic.

Second example: Double slit experiment.

Have two slits very close together. Send an electron toward the middle point of the two slits in a metallic medium; sometimes a photon will be absorbed by the medium, sometimes it will go through one slit and sometimes the other slit but we cannot without observation know which slit it went through. OK, so far so good

Now we are going to place a photon detection screen at a distance of roughly 3 feet from the slits. This screen will detect the exact position where the photon hits the screen. OK, still no problems. Now with continued events we begin to notice the classical Young interference pattern on the screen. So we ask why. So far still no problem.

Quantum mechanics says that electrons and photons can either be a particle or a wave, but not at the same time. Aether theory says that everything is simple and definite. A photon or electron is physical and via its spin produces a surrounding vortex and waves of aether relating to its spin within the aether.

In Quantum mechanics a photon (a particle) can go through both slits at once and interfere with itself on the other side. Certainly not conventional logic.

In aether theory an electron is a spinning particle that pushes out aether waves via its spin. The waves go through both slits but the particle just goes through one. The waves going through the second slit interferes with the particle producing the familiar interference wave pattern. The same thing with light and photons. In aether theory the aether waves go through both slits but the photon goes through only one. The waves from the other slit interfere with the photon during transit from the slits to the detector. The answer seems so simple that maybe a third grader could understand it. All of quantum theory can be very simply explained by aether theory and be totally compatible with Newtonian physics and even many of Einstein's ideas. Bring in an aether maybe like dark matter or particulates/ strings greatly smaller, and quantum theory, the theories relativity and maybe every other "complicated" theory would greatly change or be replaced.

All of reality may be eventually understood as being very simple with no mysteries. There is no so-called mystery in physics that I know of that I cannot explain by simple logic involving alternative theory. I think the key to understanding reality involves looking for and considering the simplest possible answers and explanations while continuing the quest to find missing ingredients such as the aether -- like we have been looking for dark matter.
