The details depend on the rate at which repulsive gravity increases, but in one representative example worked out by physicists Robert Caldwell, Marc Kamionkowski, and Nevin Weinberg, about twenty billion years from now repulsive gravity will drive apart clusters of galaxies, about a billion years later the stars constituting the Milky Way will be flung apart like sparkles in a fireworks display, about sixty million years after that earth and the other planets in the solar system will be thrust away from the sun, a few months later the repulsive gravitational force between molecules will cause
