New Astrophysical Tests from the Einstein's Equivalence Principle and Gravitational Experiments

Abstract

The Einstein's equivalence principle and experiments, in which bodies and observers are in different G potentials, have been used to prove that the chain of hypothesis coming from assuming the absolute invariability of the bodies, after a change of G potential, are wrong. The absolute changes of frequencies, masses and lengths of every well-defined part of the non-local bodies, compared with the local ones, are linearly related to the differences of G potential between the non-local bodies and the observer. Such absolute changes are independent on the forces within the structure of the bodies. Then the increase of G potential due to universe expansion also expands bodies in same proportion as distances. Consequently, such uniform expansion cannot change the results of any measurement of distance or velocity. The cosmological red shifts and the average universe density cannot change with the time, i.e., the new universe age is not limited by the Hubble law. The new linear G relationships and the unlimited age of the universe fix a new astrophysical context that turns out to be independent on any cosmological hypothesis. Thus the best fit of this new scenario with astronomical observations has been obtained independently on the chain of hypotheses that are not simultaneously consistent with all of the experimental facts.
