In this web-page I will derive an mathematical framework which shows that Einstein’s relativity theory of infinite mass increase while approaching light speed is only true as long as we neglect Quantum Mechanics which contradicts Relativity in many aspects. The theoretical approach of “Quantum-Vacuum-Relativity” (QVR) tries to harmonize these contradictions.. I will try to harmonize these classical theories of Micro- and Macro-Physics mainly by using complex number series and thermo-dynamics assumptions. Please follow my hand-writings.
