#### Abstract

The purpose of this article is to identify laws that would describe gravitation if negative gravitational mass/gravitational charge (g-charge) exists. WEP is generalized to establish correlations between mass and positive/negative g-charge (Q_(g+)/Q_(g-)), although Q_(g-) on Earth would fall upward. Newton’s theory and Einstein’s theory are generalized to describe behaviors of objects carrying Q_(g-). A significant conclusion is that, as long as Q_(g-) is introduced, all of Newton’s theory, Gravitodynamics and Einstein’s theory explain the accelerated expansion of Universe equally well without needs of “negative pressure” and “cosmological constant” that has fine-tuning issue. This implies that this mechanism of the cosmological phenomenon is universal and theory independent, which strongly supports the existence of negative g-charges. Moreover the acceleration is increasing with time. Gravitodynamics and generalized Einstein’s theory predict: (1) gravitational wave (GW_-) emitted by Q_(g-); (2) GW_- cannot be distinguished from GW_+ emitted by Q_(g+).
