‘Galileo Galilei’ (GG): space test of the weak equivalence principle to 10 ⁻¹⁷ and laboratory demonstrations

The small satellite 'Galileo Galilei' (GG) will test the universality of free fall and hence the weak equivalence principle which is the founding pillar of general relativity to 1 part in 10^(17). It will use proof masses whose atoms differ substantially from one another in their mass energy content... View More
