Universality of free fall from the orbital motion of a pulsar in a stellar triple system

Einstein’s theory of gravity—the general theory of relativity 1 —is based on the universality of free fall, which specifies that all objects accelerate identically in an external gravitational field. In contrast to almost all alternative theories of gravity 2 , the strong equivalence principle of ge...
