I don't know if i understood this, if spin is not a real spin movement, how this experiment can work with electrons?
https://en.wikipedia.org/wiki/Stern%E2%80%93Gerlach_experiment
Spin and orbit velocity of electron slows down approaching "c"?
If happen a atom to get very close the velocity "c" the time will almost
stop.
What will happen to the velocity of the orbit and spin of a electron? It
will slow down too?
