This talk outlines the entire history of the cosmos. After reviewing the history of the universe to the present epoch, we consider the evolution of planets, stars, galaxies, and the universe itself over time scales that greatly exceed the current cosmic age. The discussion follows stellar evolution and the transformation of stars into degenerate stellar remnants. After the demise of the galaxy and the evaporation of expelled degenerate stars and the largest black holes, the universe slowly slides into darkness.
