We review several tests of the M(atrix)‐Model conjecture that asserts that the dynamics of M‐Theory, the eleven‐dimensional Ur‐theory containing all known string theories and also eleven‐dimensional supergravity in specific limits, is given by a quantum mechanical matrix model. In particular, scattering processes are analyzed both from the M(atrix)‐Model and from the supergravity perspective and the corresponding S ‐matrix elements are compared. We find impressive agreement between these two theories as long as only classical supergravity is considered. If one includes also quantum effects on the supergravity side, the agreement does not persist. In addition to these calculations, the question of the existence of classical solutions to the M(atrix)‐Model equations of motion with momentum transfer is addressed and answered negatively.
