For the sake of argument, let\u2019s say that humanity survives the several ends of the world that await us.\u00a0 We somehow persist the gradual heating of our Sun and the evaporation of our oceans. Our descendants cling to existence through countless generations we watch the Andromeda galaxy merge with the Milky Way, forming a vast elliptical galaxy. We seek refuge in the outer solar system as the Sun finally expands into a red giant \u2013 twice! And finally our heirs or successors find new homes among the stars after the Sun\u2019s final death and transformation into a dim white dwarf.<\/p>\n
