Indeed it would be very strange, perhaps verging on miraculous. I believe just the
nuclear resonance discovered by Hoyle alone is already incredibly fine tuned, after
which we have the amazing properties of carbon and water, and the cosmological flatness
and god (ahem) knows what else.
Hoyle predicted that there had to be an excited state of C^12 at 7.7Mev in order to
produce the observed abundance of carbon. It was observed at 7.656Mev. But it was shown by
Livio, M. et al. (1989). "The Anthropic Significance of the Existence of an Excited State
of C12." Nature 340, 281-284, that essentially the same amount would be produced by a
resonance between 7.596Mev and 7.716Mev. Even more would be produced with a lower
resonance down to 7.3367Mev, the difference between Be^8 + He^4 and C^12. And carbon
sufficient for life would be produced up to 7.933Mev. Whether an 8% range is fine-tuned
or not, I don't think it's "incredibly fine-tuned".

If we get the constants, then to me that makes the apparent fine tuning very
strange. If there is only one physics, and that includes only "these"
constants, we
ought to be astonished and delighted that they allowed life at all. Or are
the
constants that win also bounded by anthropic reasons?
