Synopsis:
Anthropic principles: our very existence as intelligent creatures constrains the universe to be what it is (if just one of the fundamental constants were different, we wouldn't exist)
Weak Anthropic Principle (WAP): "the observed values of all physical and cosmological quantities are not equally probable but they take on the values restricted by the requirement that there exist sites where carbon-based life can evolve and by the requirement 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"
- Participatory Anthropic Principle : we are necessary to the existence of the universe, as it takes an intelligent observer to collapse the universe's waves of probabilities into concrete reality
- Final Anthropic Principle: once the universe has brought intelligence into being, it will never die out
- Life in this universe must necessarily arise given the way it is construed
- This universe has been designed for life to arise
