The airburst

Many indigenous tribes of eastern and central North America have legends about a catastrophic explosion in mid-air in the distant past.

"The Miami tell of a horned serpent that flew across the sky and dropped rocks onto the land before plummeting into the river," said University of Cincinnati anthropologist Kenneth Tankersley, himself a member of the Piqua Tribe of Alabama.  "The Shawnee refer to a 'sky panther' that had the power to tear down a forest.  The Ottawa talk of a day when the Sun fell from the sky."

Tankersley led a team of researchers who believe they know why these legends exist.  Some time between 252 and 383 C.E., they say, a comet hit the upper atmosphere over eastern North America and exploded.  The impact rained micrometeorites over most of the continent -- and, they say, would have scorched an area the size of New Jersey.  The results would have looked like the aftermath of the Tunguska Event of June 1908, in which a similar airburst flattened an estimated eighty million trees in an area of over two thousand square kilometers.

The tipoff was similar to what the father-and-son team of Luis and Walter Alvarez found in the clay layer marking the Cretaceous-Tertiary boundary, and which caused them to suspect an asteroid collision as the cause of the Cretaceous Extinction: a layer of material that is high in two rare heavy metals, platinum and iridium.  Iridium, especially, is far more common in asteroids and comets than it is on Earth, and its presence in a dust layer is suspicious, to say the least.

The impact, Tankersley et al. theorize, is part of what led to the decline and eventual collapse of the Hopewell Culture, an interconnected network of tribes that extended from what are now Manitoba and Ontario all the way down to northern Florida.  They were characterized by a particular style of pottery, jewelry, and arrowheads, but even more by the distinctive mound-building that we still see traces of in Ohio, Indiana, and elsewhere.

Something, however, triggered this confederation of cultures to go into rapid decline.  By 500 C.E. mound-building had ceased completely, and there's evidence that the trade routes that linked the different member groups were no longer being used.  The constituent tribes themselves appeared to decrease dramatically, and it took centuries for the population to rebound.

The cause, say Tankersley et al., is an airburst -- which would have destroyed completely any communities within a hundred or so miles, but would have caused extensive damage much farther away, likely triggering crop failures.  Given the fact that in most pre-technological cultures, one bad harvest was all that it took to trigger famine and starvation, something like this would have been catastrophic.

It's fascinating that like the Cascadia rupture and subsequent tsunami that made its way into the legends of the indigenous people of the Pacific Northwest, an entirely different cataclysm seems to have been recorded in the oral histories of the people of central and eastern North America.  The day the sky exploded -- with the result that an entire civilization collapsed.

The forest primeval

A couple of days ago my friend and fellow writer Andrew Butters sent me a link about a new fossil discovery.  He hastened to point out that he'd thought of me because he knows I'm interested in paleontology, not because my name comes to mind when he thinks about antiquated relics.  There may have been a touch of local pride involved as well, because the discovery was made in his home province of New Brunswick, Canada.

There's no doubt that it was a remarkable find.  The fossil was unearthed in a quarry near the town of Norton, where there is a layer of 350-million-year-old sandstone deposited when Atlantic Canada was a tropical swamp.  This was near the beginning of the Carboniferous Period, a time when the Earth was significantly warmer and wetter than it is now.  The high temperatures and carbon dioxide levels boosted plant growth, causing the oxygen levels to rise to an estimated 35% (compared to today's 21%).  This had the effect of allowing animals that had previously been held back by their inefficient respiratory systems, especially arthropods, to become huge, leading to millipedes 2.5 meters long and dragonflies with 75-centimeter wingspans.

The plants, though, were also pretty different from what we've got around now; by far the most common ones today are flowering plants, which make their first unequivocal appearance in the fossil record about 130 million years ago, in the early Cretaceous Period.  So when the New Brunswick sandstone was being deposited, the first flowering plants were still 220 million years in the future.

The dominant plants back then were distantly related to today's ferns, horsetails, and club mosses, although as you'll see we don't have anything left that looks much like what you'd see in a typical Carboniferous forest.  But the fossil discovered in the Canadian quarry was bizarre even compared to a lot of the strange vegetation from that time -- and has drawn comparisons to something you might see in a book by Dr. Seuss.

"What it really does look like is one of those truffula trees from The Lorax," said Olivia King, of St. Mary's University in Halifax, who was part of the team that discovered the fossils.  The most remarkable thing about the fossil, though, is its amazing state of preservation.  It's thought to have been entombed in an upright position when a landslide caused part of the bank of a lake to collapse.  The entire tree was dragged down to the bottom of the lake and buried in sediment, where it's lain for 350 million years -- and now has been excavated carefully to reveal what it looked like when it was alive.  Dubbed Sanfordiacaulis densifolia, after quarry owner Laurie Sanford who has been instrumental in allowing the investigation to progress, it had a mop of spiky leaves topping a spindly trunk:

With the acceleration of plant growth during that time period, there was extreme competition to access light, leading to dramatic increases in plant height and canopy size.  Eventually, there were club mosses (genus Lepidodendron) fifty meters tall -- taller than the oaks and maples in an average hardwood forest.

Of course, the good times -- at least if you were a weird club moss tree or a 2.5-meter-long millipede -- couldn't last forever.  Around 305 million years ago, the climate turned from hot and humid to cool and arid, probably because by that time the plants had locked up so much atmospheric carbon dioxide underground -- what would eventually become our coal deposits -- that the greenhouse effect decreased and the temperature fell.  In essence, the plants sowed the seeds of their own destruction, and in the Carboniferous rain forest collapse that followed, the enormous forests and many of the animals that depended upon them became extinct.

It also set the fuse for the largest mass extinction ever.  All that organic matter sequestered underground was tinder just waiting to burn, and when the Siberian Traps erupted 252 million years ago, the lava ripped through a huge chunk of the Carboniferous coal and peat, using up oxygen (dropping it to an estimated 12%) and dumping that excess carbon dioxide back into the atmosphere.  The temperature spiked, the oceans became anoxic, and something like 95% of life on Earth became extinct.

But at the point that the Sanfordiacaulis tree was growing in what would become New Brunswick, that cataclysmic event was still a hundred million years in the future.  Think about what a thrill it'd be to get to wander amongst those bizarre forests, so unlike anything we have today.

Even if it meant dodging enormous dragonflies.

Ancient UFOs

One argument against UFOs being alien visitors from other star systems is that the number of UFO sightings has risen in direct proportion to our knowledge and awareness that there are other star systems -- suggesting that they're largely a combination of overactive imagination and misinterpreting natural phenomenon (or such human-made creations as satellites and military aircraft).  The whole UFO craze, in fact, really took off during the 1940s and 1950s, when our scientific knowledge of space was accelerating rapidly.

And unsurprisingly, this was also when science fiction tropes in fiction really caught on in a big way.

Prior to the Enlightenment, the conventional wisdom in the Western World was that the skies were the domain of God and the angels, and as such were ceaseless and changeless.  (Which is why such transient phenomena as comets and novae got everyone's knickers in a twist.)  The planets weren't even considered to be places, as such; they were manifestations of powers or forces.  And if you think all that, there's no particular reason you'd look up and expect to see visitors from there, right?

So what we see, perhaps, turns out to be what we expected to see.

But it turns out that a handful of very peculiar UFO-ish incidents do come from the pre-technological world.  Now, I'm not saying any of these are actual extraterrestrial visitations, mind you; I still very much come down on the side of there being natural, no-aliens-required explanations for these phenomena.  But the fact remains that they're interesting accounts, even so.

Let's start with one observed in the days of the Roman Republic.  In 73 B.C.E., Rome was involved in the Third Mithridatic War against King Mithridates VI Eupator of Pontus and his allies.  The Roman senator Lucius Licinius Lucullus was charged with overseeing the war effort, and had decided to engage the Pontic army near Nicaea despite being outnumbered.  But then -- according to Plutarch -- the following happened:

But presently, as they were on the point of joining battle, with no apparent change of weather, but all on a sudden, the sky burst asunder, and a huge, flame-like body was seen to fall between the two armies.  In shape, it was most like a wine-jar (pithos), and in color, like molten silver.  Both sides were astonished at the sight, and separated. This marvel, as they say, occurred in Phrygia, at a place called Otryae.

Understandably, both sides decided this was an omen worth paying attention to, and called off the battle.  (I guess there was no indication of who the omen was against, so they both decided to play it safe.)  The delay didn't help Mithridates, ultimately; the Romans under Lucullus went on to fight on another day when there were fewer flaming wine-jars in the sky, and Pontus was resoundingly defeated.

So, what was this apparition?

Well, the likeliest answer is that it was a bolide -- a meteor that bursts in midair.  It's understandable how in those highly superstitious times, when omens were detected even in the entrails of slaughtered animals, such an occurrence would have sparked quite a reaction.

An even stranger one is the tale of the "Airship of Clonmacnoise," an account of a sighting that occurred in around 740 C.E. near Teltown, in County Meath, Ireland.  Here, the problem is sorting out what people actually saw from later embellishments.  The earliest versions of this story simply state that several "flying ships with their crews" were seen in the skies, but very quickly it grew by accretion.  In later iterations, the multiple ships coalesced into a single huge one, which was halted over the Abbey of Clonmacnoise when its anchor snagged on the roof of the abbey church.  A "sky sailor" climbed down a rope ladder to free it (shades of the Goblin Ship in the most recent episode of Doctor Who!), and told the astonished monks he was "in danger of drowning in the thicker air of this lower world."

Here's an account from thirteenth century monk and scholar Gervase of Tilbury:

The people were amazed, and while they discussed it among themselves, they saw the rope move as if [the crew] were struggling to free the anchor.  When it would not budge for all their tugging, a voice was heard in the thick air, like the clamor of sailors vying to recover the thrown anchor.  Nor was it long until, hope in the effectiveness of exertion having been exhausted, the sailors sent down one of themselves – who, as we have heard, dangling from the anchor rope, came down it hand over hand.  When he was about to disengage the anchor, he was seized by bystanders: he gasped in the hands of his captors like a man lost in a shipwreck, and died suffocated in the moisture of our thicker air.  But the sailors overhead, surmising that their comrade had drowned, cut the anchor rope after having waited for an hour, and sailed away leaving the anchor.

Of course, it's worth mentioning that by now the scene of the incident had shifted to London, because there's no way a good Englishman like Gervase could let such an exciting tale take place in a remote spot like central Ireland.

This one is probably just a tall tale -- although I do find the bit about the air down here being "thicker" curious, because that certainly wasn't widespread knowledge back then.

Then we have the events of the morning of April 14, 1561, when "many men and women of Nuremberg" witnessed something very peculiar.  The incident caught enough attention to be written up in a widely-circulated broadsheet the following week.  Here's how it was described by the witnesses:

In the morning of April 14, 1561, at daybreak, between 4 and 5 a.m., a dreadful apparition occurred on the Sun, and then this was seen in Nuremberg in the city, before the gates and in the country – by many men and women.  At first there appeared in the middle of the Sun two blood-red semi-circular arcs, just like the Moon in its last quarter.  And in the Sun, above and below and on both sides, the color was blood, there stood a round ball of partly dull, partly black ferrous color.  Likewise there stood on both sides and as a torus about the Sun such blood-red ones and other balls in large number, about three in a line and four in a square, also some alone.  In between these globes there were visible a few blood-red crosses, between which there were blood-red strips, becoming thicker to the rear and in the front malleable like the rods of reed-grass, which were intermingled, among them two big rods, one on the right, the other to the left, and within the small and big rods there were three, also four and more globes.  These all started to fight among themselves, so that the globes, which were first in the Sun, flew out to the ones standing on both sides, thereafter, the globes standing outside the Sun, in the small and large rods, flew into the Sun.  Besides the globes flew back and forth among themselves and fought vehemently with each other for over an hour.  And when the conflict in and again out of the Sun was most intense, they became fatigued to such an extent that they all, as said above, fell from the Sun down upon the Earth 'as if they all burned' and they then wasted away on the Earth with immense smoke.  After all this there was something like a black spear, very long and thick, sighted; the shaft pointed to the east, the point pointed west.

Like the apparition that stopped the Roman/Pontic battle, this was interpreted as an omen -- in this case, that God was even more pissed off than usual, and everyone should immediately repent and promise not to be naughty hereafter.  So once again, everyone interpreted what they saw based on their cultural context -- which, honestly, is pretty universal.  But from a more scientific standpoint, what the hell was this?

Unlike the Airship of Clonmacnoise (or Teltown or London or wherever they finally decided it happened), it's hard to dismiss this one as a tall tale.  The accounts are numerous, detailed, and -- most important, from a scientific standpoint -- all agree substantially with each other.  Skeptic Jason Colavito says that he believes the account is consistent with the atmospheric phenomenon called sun dogs, in which high-atmosphere ice crystals cause light refraction when the Sun is low in the sky, creating two bright spots (sometimes with a rainbow sheen, and often with a partial or complete halo) on either side of the Sun.

The problem is, I've seen many sun dogs, and nothing about them moves -- they can be kind of eerie, but they just hover near the horizon and eventually fade.  I've never seen a sun dog that "fell from the Sun down upon the Earth and then wasted away with immense smoke."  So for me, this one is in the "unknown" column.

Perhaps the strangest of all is the event that happened in February of 1803 in the Hitachi Province of the east coast of Japan.  Called Utsuro-bune (虚舟, hollow boat) the story was recorded in at least four separate written accounts.  The story goes that fishermen saw a strange object drifting in the ocean, and upon approaching it, found that it was a peculiar vessel "shaped like an incense burner," about 3.3 meters tall by 5.5 meters wide.  They said that the top half was "the color of lacquered rosewood," with windows made of glass or crystal, and the bottom half made of metal plates.  They towed it to land, and found that inside was a very small (but apparently adult) woman, only about 1.5 meters tall, with pale pink skin and red hair with white tips.  She spoke to them in some strange language, and could neither speak nor understand Japanese.  She clutched a rectangular metal box covered with strange inscriptions, and wouldn't let anyone touch it.

Understandably, everyone in the area was pretty freaked out by this.  After numerous unsuccessful attempts to communicate with her, or at least see what was inside the box, they gave up and decided she was too creepy to keep around.  Ultimately, they put her back into her strange vessel, towed it back out to sea, and let it drift away.

UFO aficionados naturally are predisposed to interpret this as a Close Encounter with an alien.  Certainly her odd appearance and tiny size make that explanation jump to mind.  But can we infer anything more solid from it?

The story itself is strangely open-ended -- they never find out anything more about their weird visitor, and ultimately send her back to her dismal fate in the ocean.  It hasn't the tall-tale aspects of the Clonmacnoise Airship story, nor the obvious astronomical explanation of the flaming wine-jars over Nicaea.  Some have suggested that she was simply some poor soul -- possibly Russian or western European -- who had been cast adrift.  Unfortunately, no one thought to copy the odd symbols inscribed on the metal plates of her craft; at least that'd give us information about whether we're talking about an object of terrestrial manufacture, or something more exotic.

Like the Nuremberg incident, this one was widely-enough recorded that it's hard to dismiss it entirely as a myth.  But who the woman was, and where she'd come from, are still a mystery and probably always will be.

So there are four old tales that are widely touted in UFOlogical circles as evidence of visitation.  Predictably, I'm not convinced, although I have to admit they're curious stories.  But my reaction is tempered by the fact that "it's a peculiar tale" isn't enough to append, "... so it must be aliens."  Before we jump to a supernatural or paranormal explanation, it's critical to rule out the natural and normal explanations first -- and, critically, to determine if there's even enough hard evidence to draw a conclusion.

Going against the flow

Two of the most extensively-tested laws of physics are the First and Second Laws of Thermodynamics -- and in the nearly two centuries since they were first formulated, there has not been a single exception found.

The First Law is the less shocking one.  It's sometimes called the Law of Conservation of Matter and Energy, and says simply that in a closed system, the total amount of matter and energy does not change.  You can turn one into the other, or change its form, but the total quantity doesn't vary.  Unsurprising, and in fact can seem a little circular given that this is how a closed system is defined in the first place.

The Second Law is where things get interesting.  It can be formulated a variety of ways, but the simplest is that in a closed system, the amount of entropy (disorder) always increases.  If entropy is being decreased somewhere (the system is becoming more orderly) it always requires (1) an input of energy, and (2) that somewhere else entropy is increasing, and that increase is larger than the localized decrease.  An example is the human body.  When you develop from a single fertilized egg cell to an adult, your overall entropy decreases significantly.  But in the process, you are taking the food molecules you eat and (1) extracting their energy, and (2) increasing their entropy monumentally by chopping them up into little pieces and strewing the pieces about.  So you're able to locally decrease your own entropy, but you leave behind a trail of chaos wherever you go.

Or, as my thermodynamics professor in college put it, a lot of years ago: the First Law says you can't win; the Second Law says you can't break even.  Explaining why the United States Patent Office's official policy is that any application that claims to have a working model of a perpetual motion machine goes directly into the trash without being read any further.

The Carnot Heat Engine [Image is in the Public Domain]

All of this is by way of background for a paper that I ran across in Science, called, "Heat Flowing From Cold to Hot Without External Intervention by Using a 'Thermal Inductor," by Andreas Schilling, Xiaofu Zhang, and Olaf Bossen of the University of Zürich.  Because in this paper, the three physicists have demonstrated the passage of heat energy from a colder object to a warmer one, without any external energy input -- something first shown as impossible by French physicist Sadi Carnot in 1824.

The authors write:

The cooling of boiling water all the way down to freezing, by thermally connecting it to a thermal bath held at ambient temperature without external intervention, would be quite unexpected.  We describe the equivalent of a “thermal inductor,” composed of a Peltier element and an electric inductance, which can drive the temperature difference between two bodies to change sign by imposing inertia on the heat flowing between them, and enable continuing heat transfer from the chilling body to its warmer counterpart without the need of an external driving force.

When I read this, I sat up, squinted at my computer screen, and uttered an expression of surprise that I will leave to your imagination.  In my AP Biology class, I always described the Laws of Thermodynamics as two of the most unshakeable laws of science -- two rules that are never, ever broken.  The idea that three scientists in Switzerland had taken a simple Peltier element -- a type of heat pump often found in refrigerators -- and made it run without expending any energy was earthshattering.

But before you dust off your plans for a perpetual motion machine, read the next lines in the paper:

We demonstrate its operation in an experiment and show that the process can pass through a series of quasi-equilibrium states while fully complying with the second law of thermodynamics.  This thermal inductor extends the analogy between electrical and thermal circuits and could serve, with further progress in thermoelectric materials, to cool hot materials well below ambient temperature without external energy supplies or moving parts.

I'm not going to claim I fully understand how this all works, and how despite the system's bizarre behavior it still obeys the Second Law, but apparently the key point is that despite the heat energy flowing the "wrong way," the system still gains entropy overall.

Which, I must say, was a bit of a relief.

It's still a pretty fantastic discovery.  "With this very simple technology, large amounts of hot solid, liquid or gaseous materials could be cooled to well below room temperature without any energy consumption," study co-author Andreas Schilling said, in a press release from Phys.org.  "Theoretically, this experimental device could turn boiling water to ice, without using any energy."

So don't believe any of the hype that I'm already seeing on dubiously-accurate websites, to the effect that "An Exception Has Been Discovered to the Laws of Thermodynamics!  Physicists Dismayed!  Textbooks Will Have to be Rewritten!"  It's a curiosity, sure, and pretty cool, and sounds like it will have a good many applications, but you shouldn't discount everything you learned in physics class quite yet.

Paleobling

We are hardly the only animal species that sports adornments, but most of the others -- bright colors, flashy feathers, ornate fins, and so on -- are created by genes and produced by the animal's own body.  We're one of the only ones who fashion those adornments out of other objects.

It's a curious thing when you think about it.  Virtually everyone wears clothes even when there's no particular necessity for purposes of protection or warmth; and a great many of us don such accessories as ties, scarves, hats, necklaces, bracelets, and rings.  The significance of these objects is largely culturally-determined (e.g. in western society a guy wearing a tie is a professional, someone with a ring on the fourth left finger is probably married, and so on).  Some have ritual meanings (clothing or jewelry that marks you as belonging to a particular religion, for example).  Others are simply for the purpose of increasing attractiveness to one's preferred gender.

But the odd fact remains that in the animal world, such items are almost entirely confined to the human species.

However such practices got started, what's certain is that they go back a long way.  A study that came out in Nature this week, by a team led by Jack Baker of the University of Bordeaux, has shown that not only does jewelry-making and wearing go back at least 34,000 years, the jewelry styles of prehistoric Europe belong to nine discernibly different styles -- suggesting that beads, necklaces, and the like may have been used as markers for belonging to particular cultures.

A few of the shells, beads, teeth, and other trinkets used in the Baker et al. study

The study was comprehensive, analyzing artifacts from Paviland, Wales east to Kostenki, Russia, and covering a period of nearly ten thousand years.  "We've shown that you can have two [distinct] genetic groups of people who actually share a culture," Baker said.  "In the East, for example, they were very, very much more focused on ivory, on teeth, on stone.  But on the other side of the Alps, people would have adorned themselves with really flamboyant colors: reds, pinks, blues, really vibrant colors.  If you were to see one person from each group, you could say, ‘He's from the East, and he's from the West,’ at a quick glance."

The intricacy and complexity of a particular adornment, Baker said, were probably reflective of wealth or social status -- just as they are today.

Interestingly, there was no particularly good correlation between the genetic relatedness of two groups and the similarity in their jewelry.  As Baker put it, "This study has shown really nicely that genetics does not equal culture."

Given its ubiquity -- there are very few cultures that don't wear some sort of jewelry -- you have to wonder how it got started.  Who was the first early human who thought, "Hey, I could string this shell on a piece of leather and hang it around my neck"?  Why would that thought have occurred to him/her?

And how did the other early humans react?  I picture them looking at their necklace-wearing friend and saying something like the Gary Larson/The Far Side line, "Hey!  Look what Zog do!"

It's interesting to try to consider it from the standpoint of an alien scientist studying anthropology.  How would you answer the question, "Why are you wearing that bracelet?"  Okay, you think it looks good, but why?

I'm not sure I have an answer to that.

Conspiracy crackpots

Okay, y'all, can we agree to stop calling them conspiracy theories?  A theory is a scientific model backed up by experimentation and/or observation, which is consistent with everything we know about the topic in question.

These are not theories.  We need a new term.

Maybe conspiracy batshit lunacy.  I dunno, that's more accurate, but it's a little clunky.  I'll keep thinking on it.

The reason the topic comes up (again) is because of mega-pop-star Taylor Swift and her boyfriend Travis Kelce, tight end for the Kansas City Chiefs, who will be playing in the Superbowl on February 11.  Well, Swift and Kelce made two huge mistakes, at least if you're a MAGA type; Swift endorsed Joe Biden for president in the 2020 election and is expected to endorse him again in 2024, and Kelce has appeared in commercials promoting the idea that the Pfizer COVID-19 vaccine is safe and effective.

Well.  You'd think they... I dunno.  I was gonna say "stomped all over the Constitution," but Trump himself basically did that.  Then I was going to say "threatened to drown small children," but Texas Governor Greg Abbott did that.  Then I was going to say "wanted to restrict freedom of speech," but Florida Governor (and failed presidential candidate) Ron DeSantis did that.

So comparisons kind of fail me.  Let's just say "You'd think they were really really really bad" and leave it there.

In any case, the ultra-right-wing types couldn't just shrug and say, "Taylor Swift is an American citizen and can vote for whom she likes, and Travis Kelce is free to promote the vaccine if he thinks it's the right thing to do."  Oh, no.  There has to be more to it than that.  The firestorm started almost as soon as Swift and Kelce announced they were dating, and Swift started showing up to Kelce's games.  Then Swift was named Time magazine's 2023 Person of the Year, and things really started rolling.

Here are a few quotes, to give you the idea of what sort of things are being batted about on far-right media:

• "I 'wonder' who’s going to win the Super Bowl next month.  And I 'wonder' if there’s a major presidential endorsement coming from an artificially culturally propped-up couple this fall.  Just some wild speculation over here, let’s see how it ages over the next eight months." -- Vivek Ramaswamy
• "The Democratic Party and other powers are gearing up for an operation to use Taylor Swift in the election against Donald Trump." -- Jack Posobiec
• "Taylor Swift is an op.  It’s all fake.  You’re being played." -- Benny Johnson
• "The Democrats’ Taylor Swift election interference psyop is happening in the open.  It’s not a coincidence that current and former Biden admin officials are propping up Taylor Swift and Travis Kelce.  They are going to use Taylor Swift as the poster child for their pro-abortion GOTV Campaign." -- Laura Loomer
• "All the Swifties want is a swift abortion." -- Charlie Kirk
• The NFL is totally RIGGED for the Kansas City Chiefs, Taylor Swift, Mr. Pfizer (Travis Kelce).  All to spread DEMOCRAT PROPAGANDA.  Calling it now: KC wins, goes to Super Bowl, Swift comes out at the halftime show and ‘endorses’ Joe Biden with Kelce at midfield.  It’s all been an op since day one."  -- Mike Crispi
• We're declaring a Holy War on Taylor Swift if she publicly backs the Democrats." -- an "unnamed source" quoting Donald Trump
• "Who thinks this country needs a lot more women like Alina Habba, and a lot less like Taylor Swift?" -- unsurprisingly, Alina Habba
• "Taylor Swift is a Pentagon psyop and a front for a covert political agenda." -- Jesse Watters

I could go on, but I probably don't need to.

What is astonishing to me is that very few folks listen to this and then say, "Okay, have you people been doing sit-ups underneath parked cars?  Or what?"  Evidently a significant fraction of Americans hear this stuff -- and think that it makes perfect sense.

Look, it's not that I don't know politics can get nasty, and that people -- certainly on both sides -- can do some really underhanded stuff to get elected.  But when a celebrity endorses Your Guy, and that's all hunky-dory and an example of a True American Standing Tall, but when a celebrity endorses The Other Guy it's gotta be a covert Pentagon psyop worthy of launching a Holy War, you might just want to check your thought processes for bias.

At least some mainstream media outlets are branding this wingnuttery for what it is.  CNN, in its article on the issue (linked above), labeled this stuff "loony thinking bearing little resemblance to reality," and that's not bad considering that CNN doesn't exactly have a sterling track record of calling out lunacy when they see it.  In fact, there's a good case to be made that back in 2015 the mainstream media created Donald Trump as a viable candidate by treating him as if he were one, instead of labeling him what he is right from the get-go -- an incompetent compulsive liar, a serial philanderer, a sexual predator, and a "businessman" who has a list of failed businesses as long as my arm.  But because his incendiary theatrics got listeners and readers, they uncritically publicized everything he said and did in order to keep readers and viewers engaged -- and that's a large part of why we're in the situation we now are.

At least -- maybe -- some media sources have learned their lesson.

But to return to my original point, these are not theories.  They are one of two things:

1. deliberately crazy-sounding ideas thrown out by cynical individuals who don't actually believe what they're saying, but say it anyhow because they know it'll keep the public tuned in; or
2. wild ramblings from people who think this stuff actually makes sense, in which case -- to borrow a line from C. S. Lewis -- "they're on the level of a man who says he is a poached egg."

And in neither case should we give them the slightest bit of attention, short of laughing directly into their faces.  Which is, honestly, what I'm hoping to accomplish here.

How about the Conspiracy Comedy Channel?  That at least captures the spirit of it.

The fingerprints of the Manatee

Cosmic ray is a catch-all term for the high-energy particles that constantly bombard the Earth's upper atmosphere.  The majority of them are deflected by the Earth's magnetic field or absorbed by the atmosphere, but a very few are energetic enough to reach the surface of the planet.  About 90% of cosmic rays are protons; a good chunk of the remaining ten percent are alpha particles (helium nuclei, consisting of two protons and two neutrons bound together).  The rest are varying mixes of particles from the subatomic zoo, sometimes even including positrons and antiprotons -- particles of antimatter.  They were discovered in 1912 by Austrian-American physicist Victor Hess in 1912, for which he won the 1936 Nobel Prize in Physics.

The lion's share of cosmic rays that strike the Earth originate from the Sun, but some come from much farther away.  As we've seen here several times at Skeptophilia, the universe is an energetic and often violent place, not lacking in mechanisms for sending bits of matter careening across the universe at a significant fraction of the speed of light.  As you might expect, supernovae produce cosmic rays; so do gamma ray bursters, Wolf-Rayet stars, and quasars.  The last-mentioned are thought to be supermassive black holes surrounded by an inward-spiraling accretion disk of gas and dust, which accelerates as it tumbles toward the event horizon and gives of one final death scream of radiation.  This makes quasars one of the brightest objects in the known universe, with luminosities tens of thousands of times that of the Milky Way.

Trying to pinpoint the origin of particular cosmic rays is tricky.  Being mostly made of charged particles, they're deflected by magnetic fields; so even if you find one and know the direction it was traveling when it hit your detector, you can't just trace the line backwards and assume that's the point in the sky where it originated.  So scientists who are interested in figuring out where the highest-energy cosmic rays come from -- ones that almost certainly weren't created by our placid, stable home star -- have a difficult task.

A team led by Laura Olivera-Nieto of the Max Planck Institute for Nuclear Physics has tackled this problem, and in a paper published last week in Science, came up with an answer for at least some of these mysterious particles.  Working at the High-Energy Stereoscopic System (HESS -- a nice nod to the discoverer of cosmic rays) in Namibia, Olivera-Nieto and her team are studying a curious source of cosmic rays -- black holes that are in a binary system with another star.

The current study is of an object called SS 433, a source of x-rays so powerful it's been nicknamed a "microquasar."  It lies in the middle of the Manatee Nebula in the constellation Aquila, a shell of gas and dust blown outward when a star went supernova between ten and a hundred thousand years ago.  The supernova resulted in a black hole as the doomed star's core collapsed, but its companion star lived on.

Well, after a fashion.  The enormous gravitational pull of the black hole is siphoning off matter from the companion star, and as that plume of gas spirals inward, it accelerates and gives off radiation -- just as the accretion disk of a quasar does.  The result is a jet of cosmic rays, including not only the typical charged particles but x-rays and gamma rays, which (unlike charged particles) are unaffected by magnetic fields.  This allows astronomers to pinpoint their sources.

So in the midst of this seemingly placid bit of space is a whirling hurricane of gas and dust that is accelerated so strongly it creates jets of particles moving at nearly the speed of light.  (Exactly the speed of light, in the case of the x-rays and gamma rays.)  Some of those particles eventually reach the Earth -- a few of which are picked up by Olivera-Nieto's team at HESS.

And those cosmic rays allows us to discern the fingerprints of an incredibly violent process taking place eighteen thousand light years away.
