Anthropic principle

  • “Evidence Against Fine Tuning for Life” by Don N. Page (arXiv:1101.2444; 2011.01.12) – http://arxiv.org/abs/1101.2444
      Abstract: The effective coupling `constants’ of physics, especially the cosmological constant, are observed to have highly biophilic values. If this is not a hugely improbable accident, or a consequence of some mysterious logical necessity or of some simple principle of physics, it might be explained as a consequence either of an observership selection principle within a multiverse of many sets of effective coupling constants, or else of some biophilic principle that fine tunes the constants of physics to optimize life. Here evidence is presented against the hypothesis of fine tuning by a biophilic principle that maximizes the fraction of baryons that form living beings.
