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.
