In my previous post, I suggested that we can learn from panspermia how to avoid the Origin-of-life (OOL) problem–by spreading it out. In the case of materialists from Epicurus to Hoyle, this was accomplished by making time eternal. If you have eternity to do something, they argue, why even the most improbable will necessarily occur. One can also make a spatial version of this argument by saying if the universe is infinite, then somewhere the improbable will necessarily occur. Sounds good, but…
Does this argument work?
Not the way they intend it to. For one thing, most cosmologists believe the universe to have begun in a Big Bang, which severely restricts the amount of time available for any improbable object. Likewise, many cosmologists think that the universe is finite, or at least, indistinguishable from finite size. This one is a bit trickier to argue, and so there have been many versions of an infinite universe, but every time a prediction of an observable effect is made, it turns out to fail. While there have been no lack of theories for an infinite universe, there have been no confirmations and a lot of disconfirmations, which would suggest we actually do live in a finite universe. So despite the ancient Greek belief in the infinity of time and space, the past 2500 years have been hostile to that position.
