anthropic luck is green Weak Anthropic Principle (WAP): The observed values of all physical and cosmological quantities are not equally probable but they take on values restricted by the requirement that there exist sites where carbon-based life can evolve and by the requirements that the Universe be old enough for it to have already done so. Strong Anthropic Principle (SAP): The Universe must have those properties which allow life to develop within it at some stage in its history. Because: 1. There exists one possible Universe 'designed' with the goal of generating and sustaining 'observers'. Or... 2. Observers are necessary to bring the Universe into being (Wheeler's Participatory Anthropic Principle (PAP)). Or... 3. An ensemble of other different universes is necessary for the existence of our Universe (which may be related to the Many_Worlds interpretation of quantum mechanics). Final Anthropic Principle (FAP): Intelligent information-processing must come into existence in the Universe, and, once it comes into existence, it will never die out. personally, all i've read about it is crap. 010727 what's it to you? who go blather from
