Abstract
In matrix theory the effective action for graviton-graviton scattering is a double expansion in the relative velocity and inverse separation . We discuss the systematics of this expansion and subject matrix theo ry to a new test. Low-energy supergravity predicts the coefficient of the upsilon(6)/r(14) term, a two-loop effect, in agreement with explic it matrix model calculations.
