Fr Philip Miller has an article about Faith and Science in this month’s edition of the Pastoral Review, going over some of the basic history, theology and scientific theory.
In the section on cosmology he writes about the anthropic principle: the way the universe is tuned in such a precise way as to allow the possibility of human life. I’m not sure about this. I’m not saying it’s untrue, I just haven’t done enough to think through whether I find the argument convincing or not.
What speaks to me more is the simple argument from order: that an ordered universe requires some transcendent foundation for its own order (i.e., outside space and time); and that scientific explanation presupposes that the universe can, at least in theory, be explained, and it therefore assumes that the ultimate explanation for the universe has a foundation which is outside the universe itself (at the metaphysical level – that the universe cannot contain the foundation of its own laws; and at the epistemological level – that science cannot justify the foundations of its own scientific principles).
This is how Fr Philip puts it:
The fundamental question remains, for a multiverse just as for a single universe: what is the underlying, unifying cause? The answer is that there must be a necessary being, that is, some sort of ‘God.’ Universes, being complex, law-governed entities, are not simple, and so cannot be metaphysically necessary (since ‘something’ must cause/explain the underlying unity of the complex whole).
Some of Professor Stephen Hawking’s work has been on the nature of the Big Bang, the proposed initial moment of the universe. Some of his more recent hypotheses have been to provide solutions to the complex physics of the early universe that avoid any suggestion that the Big Bang is, in effect, a creation ex nihilo. Hawking’s collaborator, physicist Neil Turok, developed the idea of the ‘instanton’ model of the Big Bang, which has, in simple terms, ‘no beginning.’ And yet, it is highly instructive to note Turok’s own words about their modelling of the universe’s initial expansion phase, termed ‘inflation’:
“Think of inflation as being the dynamite that produced the Big Bang. Our instanton is a sort of self-lighting fuse that ignites inflation. To have our ‘instanton’ you have to have gravity, matter, space and time. Take any one ingredient away and the ‘instanton’ doesn’t exist. But if you have an ‘instanton’ it will instantly turn into an inflating infinite universe.” [Turok, N., commenting online on his own work]
In other words, even in their attempt to define a universe with no beginning, they still have to assume that there is a pre-existing framework of physical laws just sitting there, which the material universe must obey. The universe clearly doesn’t invent its own laws: it requires a law-giver, and that law-giver has to be outside the universe of matter, space and time; it must be spirit, God Himself.
Which raises the child’s question, ‘But who made God?’ To which the answer is: God is not the kind of thing that needs to be made. Or, to put it in the positive: God is precisely that one ‘thing’ that is not made by another thing; God is eternal (outside time), spirit (outside space and matter), simple (outside the complexity of secondary explanations), and necessary (outside the chain of secondary causes).
