Using a nuclear equation of state derived from a finite-temperature Green's function method and the Skyrme effective interactions SkI, SkIII and SkM*, the authors have calculated the speed of sound in symmetric nuclear matter. For certain densities and temperatures, this speed is found to become super-luminous. Causal boundaries in the density-temperature plane are determined, and they indicate that SkM* is a more desirable effective interaction than SkI and SkIII. Comparison with a similar calculation by Osnes and Strottman is made.
