Query: Localization of gravitational field energy and a procedure proposed for
  its experimental verification   Introduction of Vaidya metrics into the Expansive Nondecelerative Universe
model allows to localize the energy of gravitational field. On the assumption
that there is an interaction of long-range gravitational and electromagnetic
fields, the localization might be verified experimentally. In this contribution
some details on such an experiment are given.
