Do New Findings Make Fine-Tuning of the Universe Harder to Deny?

To judge from this episode of Closer to Truth, cosmologists like Alan Guth are finding it harder than ever to rule out intelligent design of the universe

Guth: [0:53] Well, when it was first proposed in the earliest days, there was just no explanation as to what mechanism implemented the Anthropic Principle. One had the feeling that somehow behind it all there had to be some intelligent designer who was trying to design the universe for life. And I think some versions of the Anthropic Principle were really pretty explicit about that.

We have not found any sensible explanation for why there should be a cosmological constant or an energy density of dark energy, as we sometimes call it. [5:28] The magnitude that we see is vastly smaller than what we would expect. We used to think it was really zero and we didn’t understand that. But zero we were willing to accept as something that we might be able to calculate someday soon [5:39]. Now that we think it’s a small number but nonzero — and by small I don’t mean kind of small — I mean extremely small. The energy density of this dark energy is about 120 orders of magnitude less than what particle physicists would naturally guess it ought to be. [5:55]

Guth: The Anthropic explanation I think is a valid explanation. (6:37) And so far, I think it’s our only sensible explanation.[6:42] I still hope that we’ll find a better explanation ,and by better I just mean one that’s more predictive.
