Lorentz contraction effect of each electron shell around a pear shaped nucleus.
Propeller shaped Fermions are responsible for the act of contraction by plowing into the tetrahedron oscillating Higgs field!
For the origin of pear shaped nuclei (ellipsoid) according to Quantum FFF Theory, see:'
"Speakable and Unspeakable in Quantum Mechanics, chapter 9:
"How to teach special relativity" (p. 67-80)
Now we should imagine what happens at the electron shell.
The opposite effect must be working to form an spheroid shaped electron shell.
Spheroid =Ellipsoid of revolution, see image.
Pear shaped atomic nuclei is reason to assume John Bell was right!
With Lorentz contraction in special relativity.
The atom nucleus is an ellipsoid with elongated central axis.
Even Bohm and Vigier was in the right direction!
