Heuristic approach to a {\em natural} unification of the Quantum Theory   and the General Theory of Relativity
  In non-relativistic as well as in special relativistic quantum theory, {\em mass} and {\em charge} are {\em pure numbers} appearing in various (quantum) operators and admit {\em any values}, {\it ie}, values for these quantities are to be prescribed {\em by hand}. This is, in a theory of probability, understandable since we need to {\em assume} some {\em intrinsic} properties of the object we are calculating the probability about. Then, if we {\em specify}, in some satisfactory manner, mass and charge for a point of the space in a suitable general-relativistic framework, the quantum theoretical framework could, in principle, be {\em obtainable} within it. Heuristic arguments are presented to show that a {\em natural unification} of the quantum theory and the general theory of relativity is achievable in this manner.
