Last year the Nobel prize in physics went to a bunch of people that did experiments that gave rise to a so called violation of the Bell inequalities. As a consequence we are told we are living in a so called ‘non local’ universe and if you measure the quantum state of a particle here, this particle can be entangled with a particle in another galaxy and instantly that entangled particle will change or jump into another quantum state.
So the idea is that entangled particles can influence each other at a speed that is infinite so information travel is faster as the speed of light.
Well that is very interesting but when it comes to electrons and their spin state I just don’t buy that kind of crap. Why the Nobel prize committee thinks this is science worthy of their famous prize is unknown to me.
Now what is a ‘violation of the Bell inequalities’? Informally said there is too much correlation observed that cannot be explained by so called ‘hidden variables’ that are unknown. To focus the mind let me give you a simple example:
Two electrons in an electron pair get separated, one electron stays here on earth while the physics professors transport the other electron to another galaxy. It is claimed that if you measure the spin state of the electron here on earth into a particular direction, in that case the spin state of the electron that was transported by the physics professors to another galaxy instantly jumps into the other spin state. And the Nobel prize committee handed out a Nobel prize for that.
Well that is all very interesting but I think electrons carry a monopole magnetic charge and as such it is impossible to flip the spin. Take for example any chemical stuff based on binding via electron pairs, say your own body. Now if we put a magnetic field through your body tissue, does any electron flip it’s spin state? Do half of your electron pairs turn from a binding pair into a non-binding pair? No that never happens, electron spin state is not a fragile thing, it is permanent and cannot be altered.
And that is where all those experiments where they try to violate the Bell inequalities go wrong: They all assume that the photons they produce are coming from an electron that is in a superposition of spin up and spin down. But that is never the case if it is true that electron monopole charge is a permanent feature.
I have a video for you and the preprint pdf from 24 Aug 2015 that was published by the TU Delft group that did this loophole free Bell test. The video is easy and it even has music, what more do you want? The pdf is hard to read and it takes some time to grasp what is going on. I made four pictures from screenshots with a bit comment from me in it. After that the video and the pdf paper.
I do not know if they used the same electrons over and over again. Likely not because in quantum mechanics there is also the idea that if you measure some quantum property of a particle, after that in stays in that quantum state.
If electrons have a permanent magnetic charge, this must have a profound effect on the photons they produce. To be precise, the magnetic phase will be shifted 180 degrees if you compare the two different kind of photons. Without good solid proof I always assume that is why we have left and right circular photons. But information on that important detail is hard to find for years and years.
It has been a while since I updated this website with a post on magnetism. But some months back all of a sudden I would have more posts on magnetism compared to the main category of this website: The 3D complex numbers. So that is why in the last couple of months I did post nothing about magnetism over here but only on the other website.
At the end let me link you to the pdf from the preprint archive

At last I want to remark that even if you think it is very likely there is something wrong with the official version of electron spin (the tiny bipolar magnet model). In that case you must not think that for example the Nobel prize committee will come out saying they were wrong on electron spin in say the next 3 to 5 years. That’s not going to happen and that in itself is an interesting social phenomenon.
Well thanks for your attention and see you in the next post.
