They’re coming to get you, Chandra!

The crackpot wing of the astrobiology community (and I do know, there are rational and scientific members of that group!) has now flowered into full-blown paranoia. N. Chandra Wickramasinghe has published a remarkable paper on arXiv titled Extraterrestrial Life and Censorship, which isn’t as much a review of the evidence as a personal recounting of the global conspiracy to silence people who claim to have evidence of extraterrestrial life. It’s a bizarre piece of work that has the keywords “Dark
Matter;
Planet
Formation:
Cosmic
structure;
Astrobiology”, when it’s not really about any of those things; the keywords should have been “MenInBlack; They’reComingToTakeMeAway; Fools!I’llTeachThem”.

It’s strange to see Wickramasinghe constantly refer to his critics as “frightened” and characterize them as “scared out of their wits”. I have no idea what he thinks they are afraid of; he even begins the paper noting that there is nothing scary about astrobiology.

The ingress of alien microbial life onto our planet, whether dead or alive should not by any rational argument be perceived as a cause for concern. This is particularly so if, as appears likely, a similar process of microbial injection has continued throughout geological time. Unlike the prospect of discovering alien intelligence which might be justifiably viewed with apprehension, the humblest of microbial life-forms occurring extraterrestrially would not constitute a threat. Neither would the discovery of alien microbes impinge on any issues of national sovereignty or defence, nor challenge our cherished position as the dominant life- form in our corner of the Universe.


And then, with a complete lack of awareness of what he has just written, he goes on to assert that every one of his critics is terrified. Of what, I wonder? He almost gets the answer.

After 1982, when evidence for cosmic life and panspermia acquired a status close to irrefutable, publication avenues that were hitherto readily available became suddenly closed. With the unexpected discovery that comets had an organic composition, with comet dust possessing infrared spectra consistent with biomaterial attitudes hardened to a point that panspermia and related issues were decreed taboo by all respectable journals and institutions.


The peer review system that was operated served not only to exclude poor quality research but also to deliberately filter publication of any work that challenged the standard theory of life’s origins.


I’ve highlighted the important phrase there. One of the functions of peer review is to set certain standards and make a preliminary sorting of the wheat from the chaff. When you’ve got two explanations, one being that the work is excluded for its poor quality and the other being that there is active censorship of work the editors fear, and you’ve opened your paper by explaining that there is nothing to fear from astrobiology, doesn’t that imply that the first explanation is better?

As another indicator that Wickramasinghe is trying to publish garbage, I notice that throughout his paper he is remarkably incapable of noticing that “organic” and “biological” are two different words. Finding organic compounds is not evidence of biological activity.

I am getting a very poor impression of astrobiology

I received email from one of those astrobiologists, the people behind the Journal of Cosmology, in this case Carl H. Gibson. I was…amused.

Dear Professor Meyers:

I understand you have some problem with our interpretation of Richard Hoover’s article proposed for the Journal of Cosmology. I certainly hope you will write up your comments for publication in a peer review, along with the article.

Attached is an article that might interest you on the subject of astrobiology. Have you written anything in this area?

Regards,
Carl

Ah. He understands that I had some problem with Hoover’s article. I think if he takes a slightly closer look at what I wrote, he might be able to notice that I think the whole article was a creaky, broken cart loaded with rotting donkey bollocks. I thought it was perfectly clear, but I guess I have a thing or two to learn about expressing my opinions unflinchingly.

No, I haven’t published anything in the field of astrobiology. It’s not my area of interest at all, and I don’t seem to meet any of the qualifications, all of which involve being an engineer, a physicist, or a crackpot. I’m only a biologist.

I do have to thank Dr Gibson for the very interesting article he sent along. It was quite the silliest thing I’ve read in days … which is saying something, given the kind of stuff creationists like to throw over the transom. I had no idea the field was such a mucking ground for foolishness.

The paper is titled, “The origin of life from primordial planets”, by Carl H. Gibson, Rudolph E. Schild, and N. Chandra Wickramasinghe, and you can find it in the International Journal of Astrobiology 10 (2): 83-98 (2011), if you’re really interested. Almost all of it is physics and cosmology, and it’s way over my head, so that part could be absolutely brilliant, and these guys really could be shaking up the entire discipline of cosmology and I wouldn’t be aware of it. So let me just grant them that part of their story, although to be honest, the parts that I do understand make me really, really suspicious.

Anyway, they’re pushing a new cosmological model called HGD (hydro-gravitational-dynamics) in opposition to the standard ΔCDMHC model (that stands for dark energy cold-dark-matter-hierarchical clustering). They really like their acronyms, which made the paper a hard slog, but my impression is that they’re arguing that planets formed first out of turbulence in cosmic gases, congealing into dark clumps that were home to life first, and then colliding together to form stars. I have no way to tell if the physics is BS, other than that it isn’t any part of the standard models I’ve read in popular physics books, but the basic premise is that first masses condensed, then life evolved, then stars formed. Yeah, seriously.

The onset of prebiotic chemistry and the emergence of life templates as a culmination of such a process must await the condensation of water molecules and organics first into solid grains and thence into planetary cores. Assuming the collapsing proto-planet cloud keeps track with the background radiation temperature, this can be shown to happen between ~2-30 My after the plasma to neutral transition. With radioactive nuclides 26Al and 60Fe maintaining warm liquid interiors for tens of My, and with frequent exchanges of material taking place between planets, the entire Universe would essentially constitute a connected primordial soup.

Life would have an incomparably better chance to originate in such a cosmological setting than at any later time in the history of the Universe. Once a cosmological origin of life is achieved in the framework of our HGD cosmology, exponential self-replication and propagation continues, seeded by planets and comets expelled to close-by proto-galaxies.

That’s right. Life arose 14 billion years ago. They say it again in the abstract: Life originated following the plasma-to-gas transition between 2 and 20 Myr after the big bang, while planetary core oceans were between critical and freezing temperatures, and interchanges of material between planets constituted essentially a cosmological primordial soup.” We’ve also got a diagram.

That is awesomely weird. So, somehow, life evolved under the bizarre physical conditions of the early universe, under conditions completely unlike anything on earth, survived the formation of stars, incredibly low population densities, extreme variations in temperature and radiation, and drifted through space for billions of years to finally settle on the relatively warm, wet, thick oceans of ancient Earth, and found itself right at home.

And this is somehow a better explanation than that life arose natively.

Why? All they’ve got to justify this nonsense is the long discredited views of Hoyle and Wickramasinghe that 4½ billion years is not enough. And their alternative explanation is that the Big Bang produced a universe-spanning interconnected soup in which evolution occurred.

In view of the grotesquely small improbability of the origin of the first template for life (Hoyle & Wickramasinghe 1982) it is obvious that it would pay handsomely for abio- genesis to embrace the largest available cosmic setting. The requirement is for a connected set of cosmic domains where prebiology and steps towards a viable set of life templates could take place and evolve. In the present HGD model of cosmology the optimal setting for this is in events that follow the plasma-to-gas transition 300000 years after the big bang. A substantial fraction of the mass of the entire Universe at this stage will be in the form of frozen planets, enriched in heavy elements, and with radioactive heat sources maintaining much of their interior as liquid for some million years. The close proximity between such objects (mean separations typically 10-30 AU) will permit exchanges of intermediate templates and co-evolution that ultimately leads to the emergence of a fully fledged living system. No later stage in the evolution of the Universe would provide so ideal a setting for the de novo origination of life.

Never mind. I don’t think any serious biologist has any significant problems with the probability of life originating on this planet, but I think we’d all agree that the ancient planetary nebula was an even more hostile environment than the Hadean earth. I think their team needs some more competent biologists contributing — they may have the “astro” part down, but the “biology” part is looking laughable.

I do hope there is intelligent life in astrobiology, and that there are better qualified scientists who will take some time to criticize the cranks in their field.

Did scientists discover bacteria in meteorites?

No.

No, no, no. No no no no no no no no.

No, no.

No.

Fox News broke the story, which ought to make one immediately suspicious — it’s not an organization noted for scientific acumen. But even worse, the paper claiming the discovery of bacteria fossils in carbonaceous chondrites was published in … the Journal of Cosmology. I’ve mentioned Cosmology before — it isn’t a real science journal at all, but is the ginned-up website of a small group of crank academics obsessed with the idea of Hoyle and Wickramasinghe that life originated in outer space and simply rained down on Earth. It doesn’t exist in print, consists entirely of a crude and ugly website that looks like it was sucked through a wormhole from the 1990s, and publishes lots of empty noise with no substantial editorial restraint. For a while, it seemed to be entirely the domain of a crackpot named Rhawn Joseph who called himself the emeritus professor of something mysteriously called the Brain Research Laboratory, based in the general neighborhood of Northern California (seriously, that was the address: “Northern California”), and self-published all of his pseudo-scientific “publications” on this web site.

It is not an auspicious beginning. Finding credible evidence of extraterrestrial microbes is the kind of thing you’d expect to see published in Science or Nature, but the fact that it found a home on a fringe website that pretends to be a legitimate science journal ought to set off alarms right there.

But could it be that by some clumsy accident of the author, a fabulously insightful, meticulously researched paper could have fallen into the hands of single-minded lunatics who rushed it into ‘print’? Sure. And David Icke might someday publish the working plans for a perpetual motion machine in his lizardoid-infested newsletter. We’ve actually got to look at the claims and not dismiss them because of their location.

So let’s look at the paper, Fossils of Cyanobacteria in CI1 Carbonaceous Meteorites:
Implications to Life on Comets, Europa, and Enceladus
. I think that link will work; I’m not certain, because the “Journal of Cosmology” seems to randomly redirect links to its site to whatever article the editors think is hot right now, and while the article title is given a link on the page, it’s to an Amazon page that’s flogging a $94 book by the author. Who needs a DOI when you’ve got a book to sell?

Reading the text, my impression is one of excessive padding. It’s a dump of miscellaneous facts about carbonaceous chondrites, not well-honed arguments edited to promote concision or cogency. The figures are annoying; when you skim through them, several will jump out at you as very provocative and looking an awful lot like real bacteria, but then without exception they all turn out to be photos of terrestrial organisms thrown in for reference. The extraterrestrial ‘bacteria’ all look like random mineral squiggles and bumps on a field full of random squiggles and bumps, and apparently, the authors thought some particular squiggle looked sort of like some photo of a bug. This isn’t science, it’s pareidolia. They might as well be analyzing Martian satellite photos for pictures that sorta kinda look like artifacts.

The data consists almost entirely of SEM photos of odd globules and filaments on the complex surfaces of crumbled up meteorites, with interspersed SEMs of miscellaneous real bacteria taken from various sources — they seem to be proud of having analyzed flakes of mummy skin and hair from frozen mammoths, but I couldn’t see the point at all — do they have cause to think the substrate of a chondrite might have some correspondence to a Siberian Pleistocene mammoth guard hair? I’d be more impressed if they’d surveyed the population of weird little lumps in their rocks and found the kind of consistent morphology in a subset that you’d find in a population of bacteria. Instead, it’s a wild collection of one-offs.

There is one other kind of datum in the article: they also analyzed the mineral content of the ‘bacteria’, and report detailed breakdowns of the constitution of the blobs: there’s lots of carbon, magnesium, silicon, and sulfur in there, and virtually no nitrogen. The profiles don’t look anything like what you’d expect from organic life on Earth, but then, these are supposedly fossilized specimens from chondrites that congealed out of the gases of the solar nebula billions of years ago. Why would you expect any kind of correspondence?

The extraterrestrial ‘bacteria’ photos are a pain to browse through, as well, because they are published at a range of different magnifications, and even when they are directly comparing an SEM of one to an SEM of a real bacterium, they can’t be bothered to put them at the same scale. Peering at them and mentally tweaking the size, though, one surprising result is that all of their boojums are relatively huge — these would be big critters, more similar in size to eukaryotic cells than E. coli. And all of them preserved so well, not crushed into a smear of carbon, not ruptured and evaporated away, all just sitting there, posing, like a few billion years in a vacuum was a day in the park. Who knew that milling about in a comet for the lifetime of a solar system was such a great preservative?

I’m looking forward to the publication next year of the discovery of an extraterrestrial rabbit in a meteor. While they’re at it, they might as well throw in a bigfoot print on the surface and chupacabra coprolite from space. All will be about as convincing as this story.

While they’re at it, maybe they should try publishing it in a journal with some reputation for rigorous peer review and expectation that the data will meet certain minimal standards of evidence and professionalism.

Otherwise, this work is garbage. I’m surprised anyone is granting it any credibility at all.
