Here at Scientific American if nowhere else.
The real criticism of cosmological natural selection as a scientific hypothesis is its lack of direct evidence at this point. There is no direct evidence that the universe reproduces. Without that, no natural selection, even before issues of variation and selection come into play. True enough. But keep in mind that from a direct evidence perspective, cosmological natural selection is no worse off at this point than proposed scientific alternatives. There is no direct evidence that universes are created by quantum fluctuations in a quantum vacuum, that we live in a multiverse, that there is a theory of everything, or that string theory, cyclic universes or- brane cosmology even exist.
But now, at the end of science, evidence is an outdated idea anyway.
We fund whatever they dream up.
