New Theories / New Theory: Spin
« on: 10/08/2019 17:51:16 »We all know that if you would translate the spin of a electron to a 'spinning top' then it would have to spin faster than light, which is a limit for anythings speed. Then we come to this " In the not-so-recent past we delved into some of the nitty-gritty of vector bosons such as the force particles of the Standard Model. We saw that relativity forces us to describe these particles with four-component mathematical objects. But alas, such objects are redundant because they encode more polarization states than are physically present. For example, a photon can’t spin in the direction of motion (longitudinal polarization) since this would mean part of the field is traveling faster than the speed of light.

Isn't that argument flawed? That ' a photon can’t spin in the direction of motion (longitudinal polarization) since this would mean part of the field is traveling faster than the speed of light. '
I agree to that a 'spin' can't be ftl, but I find it harder to agree to that a quantum mechanical spin can't take any 'direction/polarization' it want. As this argument seems to state. A quantum mechanical spin has no classical counterpart, as far as I know?
Actually I've been wondering about that before too.
in order for anything to be stable and not to decay, it must spin in all directions simultaneously.
