Abstract
QUANTUM mechanics deals with object systems composed of only a few particles out of the total number of particles in the universe. The particles of the local object system, which may be an atom or atomic nucleus, are supposed to be incapable of dropping into vacant energy levels in the back ground consisting of the unspecified particles of the universe. Also an unspecified particle of the back ground is supposed to be incapable of falling into one of the vacant levels of the local specified system. As Eddington1 has pointed out, this means that quantum mechanics postulates that the levels of the background are all below the ground-level of the local object system, and further, that all the levels in the background are occupied by one particle, a neutral scalar particle in Eddington's theory, in each level in accordance with the exclusion principle. The limit energy of the unspecified background particles corresponds to the threshold energy of the local specified system. The background forms a uniform isotropic comparison fluid which is postulated by our statement of the quantum theory.
