Crash remnant

Well, another alleged UFO artifact has been analyzed and found wanting.

It's gotten to be a pattern, hasn't it?  Someone claims to have rock-solid evidence of something fringe-y -- hair or bone from a Bigfoot, the skull of a humanoid alien, ghost photographs, extrasensory perception -- and upon examination, it turns out to be tenuous at best and an outright fake at worst.  Nothing, certainly, that would convince an honest skeptic.

Now, allow me to state up front something I've said many times before here at Skeptophilia; I'm not a skeptic because I don't like the idea of the paranormal.  Honestly, I would love it if some of this stuff turned out to be true.  Not only is there simply the coolness factor, it would open up huge avenues for scientific research.  And don't @ me about how scientists are narrow-minded conservatives who are desperate to uphold the status quo and therefore would ignore hard evidence even if it existed; the truth is that scientists are constantly looking for new stuff, because finding something truly novel is how careers are made.  If they tend to give a suspicious side-eye at most of these claims, it's because they understand how data and evidence work.  (As astronomer Neil deGrasse Tyson put it, "We know what the hell we're looking at.")  Their training has made them all too aware of how easy it is to be misled by what what you would like very much to be true.

To quote the great physicist Richard Feynman: "In science, the first principle is that you must not fool yourself.  And you are the easiest person to fool."

That said, I find myself in much sympathy with Fox Mulder, even so.

In this case, a chunk of metal was provided to the All-domain Anomaly Resolution Office, a Pentagon program whose purpose is to check out anything odd that might have national security implications.  It was provided by To the Stars Academy, an independent research organization headed by Blink-182 front man (and UFO aficionado) Tom DeLonge.  The Academy's press release upon handing the artifact over to the AARO stated that "the material is clearly engineered with distinct layers of MgZn and Bi at structured thicknesses only microns thick" and "there is no precedent for this structured combination of materials."  Further, supposedly its composition would allow it to function as a "terahertz waveguide" (whatever the hell that is) which would give it the ability to "reduce inertial mass" -- in other words, to act as an antigravity device.

Ignoring the levitation bit for the moment, the part about there being "no precedent" for its structure highlights the problem with claiming something is an "alloy of alien origin."  Despite Georgi LaForge's analysis on Star Trek: The Next Generation that every spacecraft they run across is made of a phaser-resistant blend of whathefuckium and damnedifweknowite, there are only so many elements on the periodic table to choose from.  And there aren't any holes.  So to have a good case that a chunk of metal comes from an alien spacecraft, you have to be able to show that although the chunk might be made of the ordinary complement of chemical elements, the way it was put together is somehow different than what we could accomplish here on Earth.

Which is what DeLonge et al. are saying.  He also stated that the piece of metal comes from a crashed spaceship recovered in 1947 -- he never mentions the R-word, but that's the implication.  In any case, the AARO kind of went, "Okay, we'll look at it" (you'll have to imagine the sigh and eyeroll that probably accompanied it) and handed it over to Oak Ridge National Laboratories for analysis.

And what they found was...

... drum roll...

... it's terrestrial in origin.

The report said:

There was widespread domestic research on [magnesium] alloys for airframes, engines, weapons, and delivery systems starting in 1915 and peaking during World War II.  Many experimental [magnesium] alloys failed for reasons not well understood at the time of testing, e.g., stress corrosion cracking.  Unsurprisingly, records of failed [magnesium] alloy designs are scant.  Neither AARO nor ORNL could verify the specimen’s historical origin.  Unverifiable, conflicting personal accounts complicate its undocumented chain of custody...  The characteristics of the specimen are consistent with mid-20th-century magnesium alloy research and development projects, which often involved the use of zinc, lead, and bismuth additives for various purposes, including corrosion resistance.  The banding and structural features observed in the specimen align with manufacturing techniques from that era, such as vapor deposition.

And it doesn't have the ability to reduce inertial mass, so throw away your patent application for an antigravity/levitation device.  The Laws of Thermodynamics indicate that you can't decrease inertial mass unless you convert it into an equivalent amount of energy (the amount being determined by Einstein's equation E = mc^2).  This is not something to be undertaken lightly, as that kind of mass-to-energy conversion is how a nuclear bomb works.

You'd fly into the sky, all right, but I don't think you'd be happy about it.

In any case, if you're curious, you can find links to the complete report from AARO here.

There's nothing wrong with continuing to hope for positive results apropos of UFOs and other such alleged phenomena, and it's absolutely necessary to maintain an open mind and keep looking.  But -- disappointing as it is for those of us who grew up on science fiction -- the honest position at the moment is that the evidence we have thus far simply doesn't meet the minimum standard of what is required by science.  It'd be nice if that weren't true, and perhaps one day there'll be the proof we've all been waiting for.

But sadly, Tom DeLonge's chunk of metal from a 1947 crashed spaceship ain't it.

****************************************

The truth is out there. Probably.

I've always been dubious about reports of UFOs.

To me, they always seem to come back to anecdotal evidence, which is lousy support for what is essentially a scientific conjecture.  As eminent astrophysicist Neil deGrasse Tyson put it, "If you're ever abducted, steal something from the spaceship, and bring it back with you... because then you'll have something of alien manufacture.  And anything that's crossed interstellar space is gonna be interesting.  But until then, we can't have the conversation... 'I saw it' just isn't enough."

The problem is, UFO sightings are incredibly common.  MUFON -- the Mutual UFO Network -- is devoted to keeping track of all the UFO sightings reported worldwide, and it's a full-time occupation.  (In the first half of 2018, there were 3,627 UFO sightings reported to MUFON, of which 647 were labeled "unknown" -- in other words, not accounted for by conventional explanations, at least in their opinion.)

Michio Kaku, the Japanese-born astronomer who has become a familiar face on documentaries about alien life, has weighed in on this, and has an interesting take on things.  "Ninety-five percent of all UFO sightings can be immediately identified as the planet Venus, weather balloons, weather phenomena, swamp gas.  You name it, we've got it nailed.  It's the other five percent that give you the willies.  Five percent remain totally unexplained...  We're talking about generals, we're talking about airline pilots, we're talking about governors of states, who claim that this is beyond our understanding of the laws of physics...  We've got multiple sightings from multiple sources.  Pilots, other eyewitnesses, radar.  These are very hard to dismiss...  And those are worth investigating with an open mind."

Which, I have to admit, is a good point.  However, it bears mention that Kaku himself has come under fire for his unorthodoxy, and in fact many of his colleagues think he's seriously gone off the rails, either because he's honestly crazy or because he knows that sensationalist pseudoscience sells.  (An especially scathing critique is the seriously unflattering RationalWiki page on Kaku and his claims.)

But this hasn't discouraged both the true believers and the skeptics who agree with Kaku that despite the complete lack of hard evidence, there's still something here worth investigating.  And they've found a couple of unlikely allies recently -- a retired intelligence officer named Luis Elizondo, and (of all people) Tom DeLonge, former front man for the rock band Blink-182.

Elizondo and DeLonge are unequivocal that we need to look into this further.  "Despite overwhelming evidence at both the classified and unclassified levels," Elizondo wrote, "certain individuals in the Department remain staunchly opposed to further research on what could be a tactical threat to our pilots, sailors, and soldiers, and perhaps even an existential threat to our national security."

It bears mention that Michio Kaku (in the interview I linked above) also emphasized the potential threat.  Any civilization that had mastered interstellar travel would likely be ahead of us, technologically, by thousands or even millions of years, and would view us much like we view an anthill -- as being not only not that interesting, but essentially expendable.  "There's no reason an advanced alien civilization would come bearing gifts and ask to be taken to our leader, any more than we bring crickets to ants and ask to speak with the queen."

DeLonge's involvement is curious, not because he's a true believer -- heaven knows, a lot of celebrities have odd ideas -- but because Elizondo and the others trying to convince the government to look into UFOs more seriously are mostly ex-government staffers and scientists, such as Jim Semivan (formerly of the CIA's National Clandestine Service), Robert Bigelow (a Nevada-based defense contractor), Chris Mellon (Deputy ­Assistant Secretary of Defense for Intelligence during the Clinton and George W. Bush administrations), and Hal Puthoff (formerly employed by the CIA and the Defense Intelligence Agency).  Including a musician makes for a little bit of an odd partnership.

And honestly, DeLonge seems to be involved mostly to get the message out, especially to younger people.  Elizondo is very cognizant of his sales pitch, and his quest is to reach as many influential people as possible.  Having a rocker on your side never hurts, publicity-wise.

As for me, I don't think there's anything wrong with further investigations.  After all, there could be something to some of those sightings.  Even though I tend to be in Tyson's camp, and believe that most UFO sightings are explainable from purely terrestrial causes (including the propensity of people to make shit up), I also agree with Kaku that if there's five percent -- hell, if there's one percent -- of the UFO sightings that are legitimate and have defied conventional explanation, they're worth looking into.

Plus, there's just the fact that I would really love it if intelligent aliens existed.  There's a reason I have this poster on my classroom wall:

I would rather it if the aliens turned out to be friendly, of course.  I could do without having Earth invaded by Vogons, the Borg, the Draconians, the Cardassians, Shoggoths, the Slitheen, Xenomorphs, or the Tcho-Tcho People.  Vulcans would be more what I'm hoping for.

But I guess in these circumstances, you shouldn't be picky.

So I'll keep hoping, however the skeptical side of me keeps telling me not to hold my breath.

This week's Skeptophilia book recommendation is a fun one.  If you've never read anything by Mary Roach, you don't know what you're missing.  She investigates various human phenomena -- eating, space travel, sex, death, and war being a few of the ones she's tackled -- and writes about them with an analytical lens and a fantastically light sense of humor.  This week, my recommendation is Spook, in which she looks at the idea of an afterlife, trying to find out if there's anything to it from a scientific perspective.  It's an engaging, and at times laugh-out-loud funny, read.
