Abstract

The relevance of the sign of mass in general relativity is examined by analysing a simple model universe in which Dirac matter distributes uniformly. Mass reversal, converting a source of positive matter into one of negative matter, gives rise to a concomitant change in sign of the gravitational coupling. The principle of equivalence is invoked in order to generalize the result to all negative-matter sources. The admissibility of a Dirac source in general relativity implies that the sign of mass is irrelevant in gravitational interactions.
