Default P. Davies Paper-How bio-friendly is the universe

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.)

Ah! Thank you Jason for finding these little gems ...

Along similar lines, I have been reading a book called: "The Primal Bias"

You mean P2 ~ 1 ?

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.

Ah, I took the argument a different way! I took P2 ~ 1 to mean "life does
now exist in the Universe", but by all we know (today, at this time) is that
the probability (P1, via Hoyle) that molecules will combine randomly to form
life is P1 (much less than) 10^(-40000). 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).


Also, it's been my experience (through this NG) that not all "SETI
proponents" assume a "life principle" as described in the paper (the

self-replication.


I objected to Davies viewpoint of panspermia ... for me panspermia just says
life started somewhere else (maybe once somewhere else or maybe countless
times at many other places long before Earth, long before the Solar System
.... somehow the seeds or whatever "spawned" life came to the Solar System).
To me panspermia & "transpermia" are the same ...
