Smolins Cosmological Natural Selection - that the laws, or at least some parameters of physical law, is evolving by reproducting universes and that some variation is introduced at each generation of a new black hole/new universe, contains a basic evolutionary idea that after some evolution the a randomly picked universe are likely to be somewhat selected for it's reprodctive fitness.
This is closely related to some reasoning I have on my own, but I don't see why it is necessary to contrain the concept to black holes. In a certain sense, a black hole can be seen as an observer, who continoually learns and consumes information. But what about all other observers? I had come to the conclusion that the same idea Smoling argues for should be even more natural when applied to a general observer, not only black holes.
This way, the logic of the normal flow of time, is the same as the logic "flow of time" in the universe population. Their origin are the same principle. If we can extend the logic here to normal observer, then perhaps it's easier to try to fill in the major missing points, to understand exactly what happens during the bounce, and exactly how the variation of laws is desribed.
The idea here is that the "DNA of the laws of physics" should be encoded in the microstructure of it's population, and thus variation among the population should in principle be thought of as variation of physical law, and then instead of arguing like Smoling does, the uniformity of physical law as we see it, could be explained by that fact that equilibration has taken place for so long. The oddball particles and system has since long dissolved.
I honestly don't see what insisting on the bounce as the only way to introduce variation is necessary. From my point of view, a black hole is just a very special (extreme) observer, but as I see it the logic must be present at all levels. This also has the advantage that you need not worrt about hypothetic collections of "other universes", because the logic lined out may be played out in front of our eyes in the this same universe.
Anyway, like smolin notices I think there could be plenty of ways to falsify this once it's more developed.
Has anyone, Smolin or anyone else taken the idea into that direction? ie. extend the reasoning beyond the black houle bounce, and bring the principle to unficiation with the ordinary flow of time within a single universe?
