Order Without Design?
New Scientist, is calling The Universe: Order without design by Carlos Calle "excellent." Why?
There's nothing new here, just the same old multiverse stuff that has been critiqued. The author combines a bunch of highly speculative, mostly metaphysical, controversial theories to reach his conclusions: eternal inflation, string theory and colliding branes. There will ALWAYS be speculative, untestable "cosmological" theories, so someone can always point to the latest ones and say, "See no need for a beginning or fine-tuning by a designer--the latest science says so!" These speculative theories have half-lives measured in years, unlike the now well-established Big Bang theory.
In any case, multiverse speculations do not explain those aspects of our existence that are not necessary for our existence or survival, such as the discoverability of the universe.
