  The principle which allows to construct new physical theories on the basis of
classical mechanics by reduction of the number of its axiom without engaging
new postulates is formulated. The arising incompleteness of theory manifests
itself in terms of theoretically undefinable fundamental physical constants
$\hbar$ and c. As an example we built up a parametric generalization of
relativistic theory, where the Hubble Law and the dependence of light velocity
on time are obtained.
