'Is there a God?’ --- one of the five most important questions in contemporary physics

In June 1971, Paul Dirac (Nobel Laureate in Physics) startled his audience at the Lindau meeting by considering ‘Is there a God?’ to be one of the five most important questions in contemporary physics. He said it would be useful to approach the question scientifically: “A physicist would need to make this question precise by understanding what is meant by a universe with a God and what is a universe without a God, having a clear distinction between the two types of universes, and then looking at the actual universe and seeing which class it belongs to.”
