We've talked in this forum about Frank Tipler's Omega-Point theory of god. It's a perfect example of a consistent mathematical model with dubious application. Neither mathematics nor physics settles the question, "Is the Omega-Point God." Mathematics does tell us that even in models where the Omega-Point 'exists' it exists as an abstract idealization - not a physical point or object. Physics may eventually be able to tell us whether or not our universe is such a model. But the question "Do I want to interpret the Omega-Point as God?" is in the end, either a question for theologians, or a personal question for someone in a position to assess the literature.
