Abstract:
The general theory of relativity includes the principle of equivalence of
non-inertial reference systems and the gravitational field. This principle
determines the consistency of the basic category "space-time" and the
super-category "curved space-time". The principle of corpuscular-wave dualism
in quantum theory determines the consistency of the basic category "field" and
the super-category "quantum field". In this paper we analyze an analogous
physical principle for the relational theory. As such a principle we consider
the principle of complete absorption. It consists in the fact that a
sufficiently large number of particles should be present in the Universe in
order to complitely absorb the radiation of any source. From the experimental
point of view, this situation leads to the full equivalence of the direct
interparticle interaction and the interaction carried by a local field in
space-time.
