| contents | We discuss the possibility of a simultaneous cosmic variation of two fundamental entities: the Newtonian gravitational coupling $G$ and the electron mass $m_e$. We show that this variation can account for the late-time cosmic acceleration without invoking a cosmological constant or an explicit dark-energy fluid. We compare the derived $m_e$ variation with laboratory bounds found from Quasar absorption Spectra. Our results indicate that late-time cosmic acceleration could be a manifestation of evolving fundamental couplings, establishing a direct bridge between precision tests of gravity, particle physics and the origin of cosmic acceleration. |
