full_question: This man gives his name to a spectroscopic technique of using atomic collisions to narrow Doppler Broadening. With his student H.M. Goldenberg, this scientist erroneously found that the sun had an oblate bulge of about 42 kilometers, though he later gave a tight limit on actual solar oblateness. Those solar experiments were designed to a test a theory that features an equation that sets the covariant wave operator equal to 8 pi times the stress energy tensor divided by 3 plus two times this scientist's namesake coupling constant. After he re-performed Loránd Eötvös's experiment to confirm that inertial mass and gravitational mass were indistinguishable, this man and an alphabetically prior colleague developed a scalar-tensor alternative to general relativity For 10 points, name this cosmologist who proposed a theory of gravity with Carl Brans.
