It provides a first confirmative measurement of the fundamental speed of the Einstein general principle of relativity for gravitational field.45 pages, 6 figures, publishedGeneral Relativity and Quantum CosmologyAstrophysicsHigh Energy Physics - PhenomenologyHigh Energy Physics - TheoryClassical Physicstext
