So we know the objects in the universe are accelerating away from each other, but the edge of the universe is expanding at near the speed of light at the edge. So since the speed of light is constant and mass approaches infinity as it accelerates to that speed, how can that acceleration continue? At some point it has to reach an end, and gravity at that point however weak should eventually reach an equilibrium with the apparent force causing the expansion, theorized as dark matter perhaps. Then entropy will wind it all down and time ends right?
