 My impression is that Smolin's theory implies that new universes are
almost always rather similar to their parents (without inheritance,
evolution doesn't work). This implies that life doesn't alter the parameters
 If life can create new universes without losing mass into a black hole,
then my hypothesis is presumably false. If life can't do that, it seems
to me that the tweaking it could do would have small effects compared
to the effects it would have on the new universe production. I'm assuming
several orders of magnitude reduction in black hole production, whereas
I think that the untweaked parameters would be somewhere in the range
of 0.1 to 1 expected civilizations per universe, leaving at most one
order of magnitude of useful tweaking to increase life-filled universes.
