The Future of Science, and the Universe: “But the black hole itself radiates away its energy, so that a black hole with the same mass as the sun will in any case disappear in 1066 years or so. A galaxy-sized black hole lives longer, perhaps 10100 years. Eventually the black holes, too, will all be gone. If the Time Traveler journeyed that far forward in time, he would find no beach, no planets, no stars, no atoms, nothing but ‘creeping murmur, and the poring dark.’”
