A shortly accelerrated object contains a constant speed traveling inside the oscillating Axion vacuum or Luminuforus Ether, and will keep that constant speed without an external force acting on the onject. see also: https://bigbang-entanglement.blogspot.com/2024/10/bose-einstein-conglomerates-seems-to-be.html
A Cone-Pear-shaped Atom Nucleus seems to be needed for Ineria and Lorentz Polarization The Lorentz Fitzgerald contraction does not fit into Einsteins Special Relativity, see: https://bigbang-entanglement.blogspot.com/2024/10/a-cone-shaped-atom-seems-to-be-needed.html
However The Atomic Nucleus Contraction must be real (see: the electronshell image below) also supported by the coneshaped atomnucleus pointing into the absolute direction of motion in the oscillating Axion Tetrahedral Space Frame . (Q-FFF Theory) also called The plastic Luminifurous ether.
