In the previous post, I presented and explained an argument for the design of the universe to make possible life on earth. The universe certainly appears designed, but could our intuitions
about this be wrong? Some think so, and have offered alternate explanations.
The evidence and appearance of design is overwhelming. It seems an insurmountable challenge to explain how all the cosmological constants are so precisely calibrated to support life on earth without inferring design. Without design, the only other mechanism is chance, and as mentioned previously, the odds of all the constants falling in these “sweet spots” are practically, if not mathematically, impossible. The multiverse is an attempt to work around this problem.
In brief, the multiverse theory states that there is an ensemble of universes parallel to our own. There could be any number of other universes out there, each with different settings on their cosmological constant values. So, one may be quite different from ours, having life-crushingly heavy gravity, and another may be quite similar to our own, but perhaps having an Earth with high carbon dioxide and a runaway greenhouse effect. This multiplicity of universes are generated by some mechanism, a “machine” which produces these universes with such high quantity that eventually, one like ours would eventually pop out, develop, and evolve life.
A Multiplicity of Problems
So does the multiverse explanation offer an equal or superior alternative to a designing Agent? If so, it’s going to have to address a couple of problems.
The offering of a multiverse is an attempt at bypassing the implications of an Agent, whose properties begin to look like a personal Designer, one which we might call God. The problem here is that this explanation is, by definition as outside our universe, a metaphysical one, just as much as a belief in a God is; how can this sit well with materialists? Being outside our universe, there is no way, even in principle, to have any observation of, interaction with, or evidence for such a mechanism. To assert the existence of a multiverse ensemble or a multiverse generator is an act of blind faith exceeding the most fundamentalist theistic believer.
But even if we concede the existence of such a machine, it would also require some explanation of its origin, as noted before, an infinite regress of days (or other time units) is impossible to traverse. We must also have some explanation of its cause, and of its design, being necessarily a highly complex mechanism to be able to produce complex universes of various configurations. It seems to me that, at best, the multiverse pushes back the problem a level, but offers no solution for it.
The multiverse is an attempt to explain the appearance of design of the universe we live in. However, since it ends up not answering the question, but postponing it, and requires a lot of blind faith in an explanation without any evidence, even in principle, I find myself without any reason whatsoever to believe in such a thing.
But perhaps I’ve overlooked something. If you think so, leave me a note through the form on my “about” page, we’ll discuss, and your comments may inspire a follow-up post!
