Inertia, is related to the Lorentz polarization rotation of the atom Quark rings perpendicular to the axis of motion inside the LASOF field (below) around the atomic center axis. In addition, The pear shape of the atom will become more evident, depending of the absolute speed of the atom through the tetrahedral vacuum frame, .
LASOF is Local Anti Symmetric Oscillation Frame around the sun and earth, created by the local influenced spaceframe between the SABHs abd GABHs. ( Stellar/and Galaxy Anchor Black Hioles ) see also: What Is Wrong With Physics?https://vixra.org/pdf/1903.0102v2.pdf
Even the local lightspeed is influenced by the LASOF. see: Experiments to determine the mass related Lightspeed extinction volume around the Earth and around spinning objects in the Lab. https://vixra.org/pdf/1102.0056v2.pdf
