“There is very little hope for life of any kind surviving the big crunch in a closed universe. However, one cannot be dogmatic about this as one does not know the limits of human ingenuity. If indeed the universe is closed, we probably have tens of billions of years to think about how to survive the big crunch, if it is not against the laws of nature that something should survive.” LifeUniverseNatureSurvivalHumanCosmologyBig Crunch Book:The Ultimate Fate of the Universe Source: The Ultimate Fate of the Universe
“It is possibly true that intelligent life with a sophisticated technology is needed for the eventual survival of life. Dinosaurs and many other species became extinct because they could not adapt themselves to changes in the environment. Of course many other species have lived through many crises. But it is doubtful that any species, other than human beings (or atany rate, intelligent beings) can survive.” UniverseHuman BeingsEnvironmentSurvivalExtinctionDinosaursCosmology Book:The Ultimate Fate of the Universe Source: The Ultimate Fate of the Universe
