NASA Scientist Claims Evidence of Alien Life on Meteorite
FoxNews.com ^ | 3/5/2011 | Garrett Tenney

Posted on 03/05/2011 5:51:25 AM PST by SonOfDarkSkies

We are not alone in the universe -- and alien life forms may have a lot more in common with life on Earth than we had previously thought.

That's the stunning conclusion one NASA scientist has come to, releasing his groundbreaking revelations in a new study in the March edition of the Journal of Cosmology.

Dr. Richard B. Hoover, an astrobiologist with NASA’s Marshall Space Flight Center, gave FoxNews.com early access to the out-of-this-world research, published late Friday evening in the March edition of the Journal of Cosmology. In it, Hoover describes the latest findings in his study of an extremely rare class of meteorites, called CI1 carbonaceous chondrites -- only nine such meteorites are known to exist on Earth.

Is that a seal fetus crapping stars?

Seriously...this would be a huge discovery!

I hope its true. Hard to trust science these days...

Not betting the paycheck on this one.

When science "discovers" what some scientists desperately want to discover, I get a little cynical. And particularly when the scientists are working for an agency that isn't doing too well in the PR and funding departments at the moment.

A life form is found on a meteorite on PLANET EARTH. The life form resembles EARTHLIKE life forms.

A sensible person would conclude that the LIFE FORM CAME FROM PLANET EARTH!!!!!

One day life will be discovered on other planets. But this isn’t it.

Let me just say that I’m skeptical.

To make such a claim, one has to be able to show that there was not contamination from any source. For a meteorite found on the Earth’s surface, that’s pretty hard to do.

Just manipulating the rock in a sterile environment is not sufficient. “Sterile” means that microorganisms are dead, not that they are absent. Whatever process presumably enabled microorganisms of non-Earth origin to penetrate into the interior of the rock would allow Earth organisms to penetrate its interior.

The way I see it, to make such a claim with reasonable assurance, the rock would have to be found and manipulated away from Earth (say, on the surface of the moon or another planet). Then, all of the instruments used to manipulate it would have to be shown to be completely devoid of microorganisms or their remains. Furthermore, putative microorganisms would have to be shown to be, in fact, living or the remains of living things and not artifacts that resemble living things.

To make the claim of bona fide extraterrestrial life requires an extraordinary standard of proof.

“The exciting thing is that they are in many cases recognizable and can be associated very closely with the generic species here on earth,” Hoover told FoxNews.com. But not all of them. “There are some that are just very strange and don’t look like anything that I’ve been able to identify, and I’ve shown them to many other experts that have also come up stumped.”

Meteorites can actually come from earth. When a large meteor strikes, it can blast chunks of earth co-mingleted with meteorite fragments back into orbit, only to later return as meteorites. Could this be a possible explanation?

“To make the claim of bona fide extraterrestrial life requires an extraordinary standard of proof.”

I don’t understand where this meme came from. Basically, it’s saying “if I don’t agree with a hypothesis, then what comprises evidence to support a hypothesis is different that if I think it’s a good hypothesis.” Is there actually any scientific justification for it or is it just a rhetorical arguin’ point?

The closest you can get to that in statistics is a strong Bayesian prior agin’ the proposition, which itself has to be justified as more than someone’s whim. And actual evidence in favor of the proposition quickly overwhelms even strong priors to the contrary.

The evidence is either consistent with the hypothesis, inconclusive, or it disproves the hypothesis, regardless of the biases of the reviewer.

Personally, I don’t think there is ET life—at least not complex life. But that doesn’t change what evidence supports and doesn’t support the hypothesis.

what does this say about the theory of evolution, the supposed last word on the origin of life on earth. you know, primordial life came from the goo in the swamps. i thought there was a “consensus” on that subject.

This is a basic tenet in most jurisprudence. Extraordinary claims require extraordinary proof. Anyone who makes wild claims about anything had better bring a whole load of evidence with them.

Hmm. I was a trial lawyer for 25 years and never ran into this one. Civil trials require a preponderance of evidence. Criminal, beyond a reasonable doubt.

If you had this other standard, then whoever gets to define what’s extraordinary wins almost every time.

Yes. Of course he would say it. He was much more about polemics than science. It’s always good if you’re the guy who gets to decide what is ordinary and what is extraordinary. Then you’re the one who decides most scientific disputes.

Well, he used it specifically about alien abductions and UFO’s and in that case he was right.

I don't know about any "meme." Everything I said is based on experience as a scientist. I have no particular emotional attachment one way or the other to the idea of life existing other than on the Earth, and I think that life has probably evolved elsewhere. That has no bearing on the fact that I am highly skeptical of the claim.

In making the claim that extraterrestrial life has been found, one must absolutely and rigidly disprove the null hypotheses, which are:

--The structures observed are artifacts contained within the sample.

--The sample was contaminated.

It is simple to state these, but incredibly difficult to show them. If the structures are, in fact, microorganisms, then how can it be shown that they are of non-Earth origin? First of all, why they didn't burn up during the meteorite's plunge to Earth? How were they not destroyed by the cosmic radiation, intense cold, and vacuum that characterize space? Even if the structures are the remains of microorganisms, can one be absolutely certain that nothing could crawl inside the rock through microfractures? How can one know that the microtome used to slice the samples didn't drag something onto the pristine slice? Let's say that they are shown to be microorganisms, and their biology is unlike any we are familiar with--well, there are plenty of examples on Earth of organisms that live in extreme environments and have vastly different biologies than those we encounter on a daily basis. And so on.

To control against contamination, the analysis must be conducted in an environment where contamination is not possible--and it's hard to think of a suitable place on Earth. The only way I can see to sufficiently control against the possibility of contamination would be to examine a rock that has never been on Earth, using instrumentation built and operated remotely.

I should also point out that statistics, in this case, is completely irrelevant. In order to run a statistical analysis, you must have something to compare--when speaking of claiming that there are extraterrestrial organisms within a rock, exactly what are you going to compare? What are the appropriate statistical tests?

I don’t disagree with anything you just wrote. But nothing you would like to see is what I would call “extraordinary.” It’s just proving the case in a likely contamination-free way. The claim itself is not characterized as extraordinary. It’s just hard to prove in a rigorous manner.

I thought you were using the phrase in the Carl Sagan sense: “extraordinary claims require extraordinary proof,” which I have always regarded as a bogus concept allowing some self-designated folks to decide that hypotheses they don’t like require a different standard of proof than others they do like.

“Well, he used it specifically about alien abductions and UFO’s and in that case he was right.”

Not really. Why do the following two propositions require a different standard of proof:

“The Sears Tower is in Chicago.”

“Aliens abducted Jane Doe on Dec. 30 2001 and subjected her to bizarre probes.”

My personal belief is that 1 is likely true and 2 is likely not true. But they are both factual hypotheses subject to evidence that tends to increase or decrease the probability of their truth. Why is Sagan right that 2 requires me to accept only super-evidence on its behalf while I may accept just regular old evidence for 1?

I suspect it’s because, like me, he agreed with 1 and disagrees with 2 and because he finds people like Jane Doe annoying. In other words, he’s made up his mind and doesn’t want to argue about it. That’s fine—he doesn’t have to.

But posing his personal beliefs (supported by the consensus of all his friends who are also surely annoyed by white-trash alien believers like Jane Doe) as being important enough that their beliefs comprise the dividing line between regular old proof and super-proof strikes me as very similar to the polemics of the Grand Alchemists of the global warming debate—”We’ve made up our minds. Just stop denying AGW and get on board.”

I’ve always regarded the “extraordinary claims require extraordinary proof” saw to be a polemical, not a scientific, point. And it is almost always used polemically. The wand has been waved. I win. I’m a scientist. Now stop arguing!

What I mean by “extraordinary proof” may or may not have any relation to what Carl Sagan meant by it. I didn’t really follow Sagan, so I am not very familiar with him. I just mean that the burden of proof is greater than that encountered by most scientists in their normal work, therefore it is extraordinary.

Earth life is based on DNA. DNA is software, which tells a ribosome (via RNA) what sequence of amino acids to assemble to create a particular protein. I would be as surprised to find an alien life form based on our version of DNA, as I would to find an alien computer that ran Windows.
