This might be old stuff to Robert, but has anyone run off a detailed range
of possibilities for how such a history might affect the observable cosmos?
Assuming that life couldn't emerge until, say, five billion years ago, but
gets statistically more likely with each gigayear since (and hence
proximity to YOU ARE HERE <= ), can we chart corrections to luminosity
factors taken for granted by astronomers who assume an unengineered
universe? If closer galaxies are stochastically dimmer or red-downshifted,
mustn't this do something interesting to the canonical calculated recession
rate and hence projected closure vs. openness?
