One problem is that society has never agreed on a standard of what is safe in these surreal realms when the odds of disaster might be tiny but the stakes are cosmically high. In such situations, probability estimates are often no more than “informed betting odds,” said Martin Rees, a Cambridge University cosmologist, the astronomer royal and the author of “Our Final Hour.” Adrian Kent, also of Cambridge, said in a paper in 2003 reviewing scientists’ failure to calculate adequately and characterize accurately risks to the public, that even the most basic question, “ ‘How improbable does a catastrophe have to be to justify proceeding with an experiment?’ seems never to have been seriously examined.”
