Equivalence Principle test in space

Abstract

The discovery of “Dark Energy” and the fact that only 5% of the mass of the Universe is explained by current Physics laws have led to a serious impasse. A very high-accuracy space test of the Equivalence Principle with the GG (“Galileo Galilei”) mission would prove or rule out the existence of a new long-range interaction in Nature and be a crucial asset for the future of Physics and Cosmology
