Comet probes reveal evidence of origin of life, scientists claim
Recent probes inside comets show it is overwhelmingly likely that life
began in space, according to a new paper by Cardiff University scientists. http://theanalystmagazine.com/pr/n312.htm Professor Chandra Wickramasinghe and colleagues at the University's Centre for Astrobiology have long argued the case for panspermia - the theory that life began inside comets and then spread to habitable planets across the galaxy. A recent BBC Horizon documentary traced the development of the theory. From where can I get the original paper? Please help |

Check out your nearest trash can. ;-) Seriously, I don't believe CW and cronies have ever published such a paper, at least not in a refereed journal. Until they do, their claim ain't worth a damn... |

When I get home from the coffee shop I am now at I will check to see if they have published in a refereed journal. I have access to my college library of academic journals. We will see if these authors are legit or not. |

We will see if these authors are legit or not. I found one article by "Wickramasinghe, Chandra" in in an online search of academic journals using my college library's interface to "Academic Search Premier" Citation Title: The universe: a cryogenic habitat for microbial life. Authors: Wickramasinghe, Chandra Source: Cryobiology; Apr2004, Vol. 48 Issue 2, p113, 13p Document Type: Article Subject Terms: *COMETS *COSMIC grains *MICROORGANISMS SOLAR system Author-Supplied Keywords: Panspermia Comets Interstellar dust Microorganisms Abstract: Panspermia, an ancient idea, posits that microbial life is ubiquitous in the Universe. After several decades of almost irrational rejection, panspermia is at last coming to be regarded as a serious contender for the beginnings of life on our planet. Astronomical data is shown to be consistent with the widespread distribution of complex organic molecules and dust particles that may have a biological provenance. A minuscule (10 21) survival rate of freeze-dried bacteria in space is all that is needed to ensure the continual re-cycling of cosmic microbial life in the galaxy. Evidence that terrestrial life may have come from elsewhere in the solar system has accumulated over the past decade. Mars is seen by some as a possible source of terrestrial life, but some hundreds of billions of comets that enveloped the entire solar system, are a far more likely primordial reservoir of life. Comets would then have seeded Earth, Mars, and indeed all other habitable planetary bodies in the inner regions of the solar system. The implications of this point of view, which was developed in conjunction with the late Sir Fred Hoyle since the 1970s, are now becoming amenable to direct empirical test by studies of pristine organic material in the stratosphere. The ancient theory of panspermia may be on the verge of vindication, in which case the entire universe would be a grand crucible of cryomicrobiology. |

At the very least it shows the sloppy thinking of the author. After several decades of almost irrational rejection, panspermia is at last coming to be regarded as a serious contender for the beginnings of life on our planet. A personal attack against the people who aren't convinced by the "evidence" presented. That's another obvious tipoff. Not only that, but the reversed use of the term irrational pretty much seals the deal. The unwillingness to accept as fact a hypothesis without any compelling evidence to support it is in fact rational. The strong belief in said idea without such compelling evidence--that's irrational. End of lesson. If only the panspermia hypothesis itself were as easy to pigeon hole. -- Greg Crinklaw Astronomical Software Developer Cloudcroft, New Mexico, USA (33N, 106W, 2700m) SkyTools: http://www.skyhound.com/cs.html Observing: http://www.skyhound.com/sh/skyhound.html Comets: http://comets.skyhound.com To reply take out your eye |
