John,
Your 2 descriptions both loosely describe what I hypothesised, but a Majorana fermion is found to be 'it's own antiparticle' which is exactly the paired opposing polar spin states of a SINGLE sphere of torus! Think about that for a bit; we can never interact with both hemspheres at the same time, so only FIND either clockwise OR anticlockwise (+1, OR -1)!!
Yes it's 'motion' (of matter) that creates the vortices. Electrons (or rather all fermions) then don't 'produce' spin, they ARE spin! The energy density reduces around the vortex so the overall spin density distribution in the greater area around a 'vortex' will be 'flat'. We'd experience the local uneven density distribution around matter as 'gravity'. If the matter is 'annihilated' the potential goes flat (no gravity).
The validity of that general approach is supported by the resolving power of the model when turned to QM. i.e. the astonishing classical derivation emerges!
EM waves (fluctuations) can only propagate in the ether at c, but not 'couple' or be modulated by it. However interaction with fermions DOES modulate, to LOCAL c giving CSL, so producing the effect we call SR in the process.
Does that help your understanding of the hypothesis, or compatibility with you own model?
Very best. (Yours is on my list)
