The Measurement Problem of the General Matter Field Theory as Required by the Copenhagen School

Abstract

In the famous Einstein-Bohr debates, a fundamental requirement of the Copenhagen school was the resolution of the problem of the ‘measurement’, when described in special cases by macro-variables and of the ‘measured’, when described by micro-variables. This could not be accomplished by Einstein in his formulation of the general theory of relativity, as it does not exhibit the inertial manifestations of matter. In accordance with Bohr’s view of quantum mechanics, these variables are introduced necessarily, asymmetrically, the ‘observer’ component obeying the rules of classical physics and the ‘observed’ component obeying the rules of quantum physics. In the general matter field theory initiated by M. Sachs, the variables of the ‘observer’ and of the ‘observed’ are introduced symmetrically as component fields of a closed material system that obey the same rules — the rules of the general matter field theory. The introduction of these variables in this relativistic field theory is done in a fully covariant manner, with a unified field approach — the general relativity and matter fields — that explicitly exhibits the inertial manifestations of matter. So, one of the problems that arose in the famous Einstein — Bohr debates is resolved and a fundamental requirement of the Copenhagen school is fulfilled.
