The Five Ages of the Universe Quotes

“This glimpse into the future offers an extreme change in perspective. Measured by the clock of a human lifetime, or even the current ten-billion-year age of the universe, the proton lifetime is so long that we usually consider them to live forever. When protons are produced by black hole evaporation, however, the proton lifetime is so short compared to the age of the future universe that they might as well decay instantaneously”
― Fred Adams, The Five Ages of the Universe: Inside the Physics of Eternity
