Probably the most underrated fing about spin is that it is a generic property of conservative fields, so it goes beyond quantum theory.

A consequence of this is you can formulate mathematically and then actually construct physical scenarios in a lab with spin in generic classical fields that are not electromagnetism or quantum.

They have done this for water and acoustic sound, formulating their spins mathematically and then observe in empirically in a lab.

What they find is that spin is microscopic particle orbits (like little water particles but they done it for sound as well) around points in space. You can see the actual microscopic orbits of tracer particles in my pic, from a study. They also clearly distinguish the microscopic orbits of spin angular momentum from the kind of orbiting, translational drift of orbital angular momentum.

So heres the thing. If quantum mechanics is point particles... there is absolutely no way spin is not going to be exactly the same as in my picture.

The issue is that no one thinks quantum theory is point particles.
