I resented accepting the anthropic reasoning for a long time. However, having noticed that there is an undeniable logic to it, I’ve come to accept it as a “last resort”, if other explanations fail and the anthropic reasoning makes sense.

Does the multiverse require string theory? At the moment string theory is struggling with no signs of super symmetry detected at the LHC. In addition string theory is not a complete theory as it is background dependent and does not in itself explain space. Quantum loo gravity or some variant of it seem to be more promising paths at the moment,. Can a multiverse theory remain consistent if quantum loop gravity is found to be the correct description of the basis of our universe.

Yes this theory has both explanatory and predictive power and arguably also satisfies Occam’s Razor

It sounds to me like a ´Cogito ergo sum´ theory. I think, therefore I am, or – differently put – I observe this type of universe, therefore its laws must be hospitable to our kind of intelligent life. If it were inhospitable to life as we know it, we would not be here to observe it. It may be circular, but no more circular than Descartes.

Anthropic principles of variation means there is no place like home.

The physics of the universe we have familiarity with, then set under other templates, is complicated to fathom, but not unreasonable if it is the reality of how we fit into a larger picture.

Again hmm, another unprovable theorem, maybe physics is the same in all universes, and it always produces the same phenomena we’re seeing and why there never was an horizon problem. Homogeneity came from physics so doesn’t rely on information transfer faster than light?

Yes This theory has both explanatory and predictive power and arguably, considering the time of the Universe, the events that occurred millions of years ago, I think it’s an interesting theory, we are here because of the physical laws that govern our universe, and nothing else.
