“…In the same vein, gauge invariance specializes to frame invariance for this Euclidean model. In this connection, the proposed geometry respects the CPT invariance, where a left-handed positron is identified with a right-handed electron via a spatial transformation, hence providing an explanation of the anti-matter asymmetry and thereof a potentially more efficient way to produce and store anti-particles, benefiting medical technology for example [9], and otherwise it furnishes the quantum vacuum a physical space of wave energies, with their energy densities identified as probability densities via their formal resemblance.…”
