A symmetrical interpretation of the Klein-Gordon equation

Abstract. This paper presents a new Symmetrical Interpretation (SI) of relativistic quantum me-chanics which postulates: quantum mechanics is a theory about complete experiments, not particles; a complete experiment is maximally described by a complex transition amplitude density; and this transition amplitude density never collapses. This SI is compared to the Copenhagen Interpretation (CI) for the analysis of Einstein’s bubble experiment. This SI makes several experimentally testable predictions that differ from the CI, solves one part of the measurement problem, resolves some in-consistencies of the CI, and gives intuitive explanations of some previously mysterious quantum effects. 1
