We wrote the other day about how the dark energy of the universe is fine-tuned to a value of 1 part in 10(120) and exclaimed about the incomprehensible precision of such a value. Yet dark energy is not the only quantity in the cosmos whose value must be unimaginably precise in order for the universe to be a place capable of sustaining life. There are dozens of additional parameters, forces, and circumstances that must be set just right in order for life to arise and survive somewhere in the vastness of the cosmos.
For example, there is a huge amount of mass in the universe, but there cannot be just any amount if the universe is going to be suitable for life. The amount has to be precisely what it is. If it were off by 1 part in 10(60) at its inception the universe would have been rendered unfit for life. This is, astonishingly, an amount of mass equal to just one dime.
If a dime's worth of mass (actually mass-energy) had been added or subtracted from the total at the initial creation event it would, among other things, have caused the universe to either expand too fast (if the mass were less) or cause all stars to be too big (if the mass were greater). In either case life could never have arisen.
As we've pointed out before, skeptics have only one way to avoid the conclusion that this universe is not an accident - that it's the product of purpose and brilliant design - and that is to assume, without any evidence whatsoever, that there are an infinite number of worlds with an infinite variety to them. If that were so then one of them would have to have the properties our world does, no matter how astronomically improbable that may seem, and we just happen to be in it.
In other words, the skeptic scoffs at believers for thinking there's a Creator who designed the universe while they, in their desperation to avoid that conclusion themselves, embrace the theory that there's an infinity of universes for which the only real evidence is the fact that if there isn't this "multiverse" then there must be a Cosmic Designer. Pretty funny.
