Description
Cosmological models of emergent modified gravity allow departures from the dynamics of general relativity in the high and low-curvature regimes without additional degrees of freedom. Consequently, emergent modified gravity is not only able to replace the big bounce singularity with a nonsingular bounce from a purely modified gravity perspective without exotic matter fields, but also to reproduce the late-time expansion rate that is commonly attributed to the effects of a weakening dark energy by the introduction of a modification function of the phase space in the Hamiltonian.
