We might find definitive proof that stars are older than black holes, just as cosmologists had long supposed. But even so, black holes would still retain some claim to ontological primacy, because they last so much longer. From their perspective, a star is just a transitory stage, a chrysalis. If the universe continues to expand as cosmologists predict, a day will come when star formation will cease altogether. Tens of trillions of years after that, the final stars will burn out. When that last stellar ember cools and darkens, the age of black holes will still be in its early days. Black holes will exist far, far longer than the entire illuminated age of stars. Of all the forms that this cosmos assumes, they will be among the most enduring. In a deep sense, this universe is theirs.
