  This paper presents a new Symmetrical Interpretation (SI) of relativistic
quantum mechanics 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 inconsistencies of
the CI, and gives intuitive explanations of some previously mysterious quantum
effects.
