Paper - How bio-friendly is the universe, by Paul Davies at
http://www.arxiv.org/abs/astro-ph/0403050 The paper posits 'biological determinism' as a factor in biogenesis, "transpermia" versus "panspermia" and that "...the key property of life is its information content, and speculate that the emergence of the requisite information-processing machinery might require quantum information theory for a satisfactory explanation." (Note the life probability number ascribed to SETI.) TTFN, Jason H. |

Yes. In context "...SETI proponents, who tacitly assume a life principle, have frequently asserted P2~1 for a single earth-like planet, implying an enormous amplification factor of 10^40,000." I don't think that scientists who are "SETI proponents" make this assertion. I think that many SETI proponents who are scientists are applying the scientific method (and asserting that there is no evidence of ET life in the universe) and they entertain the possibility that life is ubiquitous (but certainly they are NOT making any scientific assertions or observations based on such a factor, i.e. "SETI" proponents are not making the assumption that almost every earth-like planet of similar age has life on it; their targeting criteria for detection doesn't even include earth-like planets, yet.) I think there are ASTROBIOLOGISTS who make a good argument for such a possibility, but I don't think that "SETI" scientists use or would assert that number. Also, it's been my experience (through this NG) that not all "SETI proponents" assume a "life principle" as described in the paper (the religious, rare-earthers, etc.) And I wonder if many "SETI proponents" (if even a majority) are still subscribers to the theory of life arising from a world-covering ocean that is a "homogenous medium of pre-biotic building blocks such as nucleotides and amino acids." as described in the paper. Also, as Davies morphs "panspermia" into "transpermia", he limits transpermia to very local activity, and by doing so seems to omit the possibility of comets as a vector for life (those "Red Rain of Kerala" self-replicating protein from comet papers seemed a plausible life transmission medium idea (IMO), and seemed probability-wise (again IMO) a more likely scenario than oceans of nucleotides and amino acids spontaneously instigating self-replication.

So there is this "stupendous" amplification factor of P2/P1 for life. It is tantamount to saying "and then a miracle occured"!! This is nothing new, it is just worded differently!! All it says is: "hey we got a puzzle here"!! Obviously, there is a great void in our understanding of the physics (biology, ... science, ...) for the first creation of life (aside from religious factors, which in my view solves no problem because then I wonder where God came from. Logic must rule .... magic is not acceptable to me anyway ...). Obviously it wasn't a "random" coming together of atoms into molecules into life! There must be some selection process that biases the odds. What it is exactly, no one now knows ... I would differ in your viewpoint as to what SETI scientists believe. They believe passionately :-) that there IS someone ELSE out there and that is what drives them!! But they are going to use the scientific process to prove they really out there or not (this is their discipline!!). This is what I think (believe).
