In many ways, to look at a black hole is to look at the inevitable future of our Universe, because there will come a time—many trillions of trillions of years from now, but inevitable nonetheless—where all the sky’s stars will have gone out, and black holes will be the Universe’s main attraction, still gobbling down any remaining free clumps of matter and acting as the only sources of light left. And perhaps most creepily of all, if proton decay turns out to be a thing, this future black hole era will be how our cosmos spends the majority of its life—dark, silent, and forbiddingly empty.
