1st, as to _scientific_ implications, I've always felt that the "unsettling"
character of such a result - if it holds up - is due to unjustified prejudice against
the cosmological constant. Yes, Einstein renounced it & called it his "greatest
blunder" - but we don't do physics on Einstein's authority. The fact that he introduced
the cosmological term for a reason later seen to be unsound shouldn't make it out of
bounds for all future work.
Theologically, this doesn't produce an eschatological scenario fundamentally
different from a model whose expansion slows down but never stops. My paper on physics
& eschatology in _dialog_ next year will deal with some of these issues.
