Life converges

One of the most fascinating features of biological evolution -- particularly as it applies to the possibility of life on other planets -- has to do with the concept of constraint.

Which features of life on Earth are, in some sense, inevitable?  Are there characteristics of terrestrial organisms that we might expect to find on any inhabitable world?  Stephen Jay Gould looked at this question in his essay "Replaying the Tape," from his brilliant book on the Cambrian Explosion, Wonderful Life:

You press the rewind button and, making sure you thoroughly erase everything that actually happened, go back to any time and place in the past -– say, to the seas of the Burgess Shale.  Then let the tape run again and see if the repetition looks at all like the original.  If each replay strongly resembles life’s actual pathway, then we must conclude that what really happened pretty much had to occur.  But suppose that the experimental versions all yield sensible results strikingly different from the actual history of life?  What could we then say about the predictability of self-conscious intelligence?  or of mammals?

Some features that have been suggested as evolutionarily constrained, with arguments of varying levels of persuasiveness, are:

• a genetic code based on some kind of nucleic acid (DNA or RNA, or some chemical analogue)
• internal cell membranes made of phospholipids, to segregate competing chemical reactions from each other 
• multicellularity, with some level of tissue specialization
• in more complex organisms, some form of symmetry, with symmetrically-placed organs
• some kind of rapid-transit system for messages, analogous to our nervous system (but perhaps not structured the same way)
• cephalization -- concentration of the central processing centers and sensory organs near the head end

It's interesting when science fiction tackles this issue -- and sometimes comes up with possible pathways for evolution that don't result in humanoids with strangely-shaped ears and odd facial protuberances.  A few that come to mind are Star Trek's silicon-based Horta from the episode"Devil in the Dark," the blood-drinking fog creature from "Obsession," the giant single-celled neural parasites from "Operation Annihilate," and Doctor Who's Vashta Nerada, Not-Things, Gelth, and Midnight Entity.

So the search for extraterrestrial life requires we consider looking not only for "life as we know it, Jim," but life as we don't know it.  Or, more accurately, to consider to what extent our terrestrial biases might be blinding us to the possibility of what evolution could create.

It's worth considering, however, how often evolution here on Earth ends up landing on the same solutions to the problems of survival and reproduction over and over again, a phenomenon called convergent evolution.  Eyes, or analogous light receptor organs, have evolved multiple times -- some biologists have suggested as many as fifty different independent lineages that evolved some form of eye.  Wings occurred separately in four groups of animals -- birds, pterosaurs, insects, and bats.  (If you include structures for gliding, add flying squirrels, sugar gliders, colugos, flying fish, and flying lizards.)

Even biochemical pathways can reappear, something I find astonishing.  Take, for example, the research that came out this week in Nature Chemical Biology, which found that two only distantly-related plants -- ipecac (Carapichea ipecacuanha), in the gentian family, and sage-leaved alangium (Alangium salviifolium), in the dogwood family, have both come up with complex biochemical pathways to generate the same set of bitter, emetic compounds -- ipecacuanha alkaloids.

The last common ancestor of these two species was over a hundred million years ago, so there's a strong argument that they evolved this capacity independently.  And indeed, when the biochemists looked at the enzymatic pathways, they're different -- they found entirely different chemical synthesis methods for producing the same set of end products.  Weirdest of all, they both evolved an enzyme that cleaves a sugar molecule from the alkaloid precursor, and that's what activates it (i.e., makes it toxic).  In the living plant's tissues, the enzyme and the precursor are segregated from each other.  It's only when they're brought together -- such as when a herbivore chomps on the leaves -- that the sugar is split away from the precursor, the alkaloid is activated, and the herbivore starts puking its guts up.

Clever strategy.  So clever, in fact, that it was stumbled upon by two entirely separate lineages of plants.  The rules organisms play by are the same, so perhaps not surprising there are similar outcomes sometimes.

The whole thing highlights the fact that there is a limited range of solutions for the fundamental difficulties of existence.  It has to make you wonder if, when we do find life elsewhere in the universe, it might look a lot more familiar that we're expecting.  I don't think it's likely we'll bump into Romulans or Ice Warriors or Krillitane, but maybe there are features of life on Earth that will re-evolve in just about any conceivable habitable planet.

But hopefully there won't be any Vashta Nerada.  Those things are terrifying.

In praise of kindness

As someone who considers himself a de facto atheist -- I'm not certain there's no God, but the facts as I know them seem to strongly support that contention -- one question I've been asked rather frequently is where my moral compass comes from.

The answer for me is that I like being kind.  Treating other people well makes them feel good, and in general makes my own life better.  Times that I've been mean or uncharitable, on the other hand, leave me feeling sick inside.  I still remember with great shame times I've been nasty to people.  It didn't, then or now, make me happier to be unpleasant, even when on some level I felt (at the time, at least) the person might have deserved it.

I agree with the wise words of the Twelfth Doctor:

Being asked why I'm moral if I don't think there's a deity watching has always brought to mind the riposte -- although I've never said it to someone directly -- that if the only reason you're moral is because you think some powerful entity is going to punish you if you're not, then maybe you are the one whose ethics are suspect.  As Penn Jillette put it:

The question I get asked by religious people all the time is, without God, what's to stop me from raping all I want?  And my answer is: I do rape all I want.  And the amount I want is zero.  And I do murder all I want, and the amount I want is zero.  The fact that these people think that if they didn't have this person watching over them that they would go on killing, raping rampages is the most self-damning thing I can imagine.

This is why I was intrigued by a study that came out this week in the Journal of the American Psychiatrical Association, by Jessie Sun, Wen Wu, and Geoffrey Goodwin, called, "Are Moral People Happier?"  And this -- finally -- provides an exception to Betteridge's Law: an article title in the form of a question where the answer appears to be a resounding "Yes."

The authors write:

Philosophers have long debated whether moral virtue contributes to happiness or whether morality and happiness are in conflict.  Yet, little empirical research directly addresses this question.  Here, we examined the association between reputation-based measures of everyday moral character (operationalized as a composite of widely accepted moral virtues such as compassion, honesty, and fairness) and self-reported well-being across two cultures.  In Study 1, close others reported on U.S. undergraduate students’ moral character.  In Study 2, Chinese employees reported on their coworkers’ moral character and their own well-being.  To better sample the moral extremes, in Study 3, U.S. participants nominated “targets” who were among the most moral, least moral, and morally average people they personally knew.  Targets self-reported their well-being and nominated informants who provided a second, continuous measure of the targets’ moral character.  These studies showed that those who are more moral in the eyes of close others, coworkers, and acquaintances generally experience a greater sense of subjective well-being and meaning in life.  These associations were generally robust when controlling for key demographic variables (including religiosity) and informant-reported liking.  There were no significant differences in the strength of the associations between moral character and well-being across two major subdimensions of both moral character (kindness and integrity) and well-being (subjective well-being and meaning in life).  Together, these studies provide the most comprehensive evidence to date of a positive and general association between everyday moral character and well-being.

What I find fascinating about this -- and relevant to the question about religion's role in morality -- is that these findings were robust with regards to such factors as religiosity.  The sense of well-being that comes from acting ethically doesn't appear to come from the belief that God approves that sort of behavior.  (At least not across the board; clearly different people could experience different sources of well-being from moral behavior.)  The fact that just about everyone is happier when they behave with kindness and integrity indicates there's something inherent about good moral character that fosters a positive experience of life.

For me personally, I think it's a combination.  As I said earlier, being nice to people and behaving fairly means the people around me are more likely to be pleasant and fair in return.  But there's also an internal component, which I can sum up as "liking who I see in the mirror."  Shame has to be one of the most deeply unpleasant emotions I can think of, and realizing I've been awful to someone -- even remembering those times years later -- leaves me feeling ugly.  Perhaps I'm not motivated by the idea of some deity watching me, but I know that I'm watching me.

And that's enough.

Or, it usually is.  I'm certainly far from perfect.  I can act uncharitably sometimes, just like all of us.  But I try like hell to treat people well -- even those who seem not to deserve it.  I guess I'm aware that all of us are big messy morasses of competing motivations, emotions, and drives, and all of us have years of experiences that have shaped who we are in good ways and bad.  It's usually best to give people the benefit of the doubt, and not to judge others too harshly.

After all, who knows who I'd be if I had their past and lived in their present situation?  I might not even handle it that well.

It reminds me of something a dear family friend named Garnett told me when I was something like six years old.  I had my knickers in a twist over something that had happened at school, and I was complaining about a classmate to Garnett.  What she said flattened me completely, and I've never forgotten it.

"Always be kinder than you think you need to be, because everyone you meet is fighting a terrible battle that you know nothing about."

Send in the clones

You've all heard about the whole Reptilian Alien thing, right?  That prominent individuals, especially world leaders but also including a lot of entertainers, are actually aliens in human suits?  

Well, I can go you one better.  Many of those prominent individuals aren't aliens, they're actually cleverly-wrought doubles.  Clones.  Twins from different mothers, as it were.

And this highly compelling scientific claim just got a boost a couple of days ago from Mr. Grip-On-Reality himself: Donald Trump.

Trump shared the following post on the ironically-named Truth Social:

The text, in case the image doesn't load well, says, "There is no #JoeBiden - executed in 2020.  #Biden clone doubles & robotic engineered soulless mindless entities are what you see.  >#Democrats don't know the difference.  #Steel #ussteel #MAGA #MAHA"

When I first saw this, I thought, "Surely this has to be fake.  Even Trump isn't crazy enough to share something this stupid."

Being hopeful these days is a losing proposition.  It's quite real, and was even reported on Fox News, which has usually taken great pains to depict Dear Leader as the smartest person in the world now that Stephen Hawking is dead, instead of the reality, which is that Trump was pretty fucking dumb to begin with and in the last few years has shown every sign of progressive dementia.

The thing is, the whole "replaced by clones" claim isn't new, although this is the first time I've heard it espoused by Trump (or applied to Biden).  I did a little bit of research on the topic, at the expense of brain cells I can ill afford to lose, and discovered there's a Doppelgänger and Identity Research Society which keeps track of this alleged phenomena.  And they're not talking about simply spotting someone who looks a bit like a famous person, or perhaps resembles yourself (an unsettling occurrence that happens to just about everyone once or twice in their lives).  These people claim that unlike ordinary twins, or even clones, in which both individuals coexist, here the duplicate has replaced the original, and the original is no more.

In other words: Brad Pitt isn't actually Brad Pitt, he's someone who looks, talks, and acts exactly like Brad Pitt.

Upon reading this, I was reminded of the quote from Spock on Star Trek: "A difference that makes no difference is no difference."  If there's only one Brad Pitt -- i.e., no one is really claiming that there are two of 'em walking around, as far as I can see -- and he is identical to Brad Pitt, doesn't that make him, um, Brad Pitt?

Apparently not.  Here's an explanation of the difference, from the site:

Human doubles are made by other humans from the DNA of a single cell, where a replica of the physical body is reproduced.  That clone is only physical and has no soul, therefore, it has no God-connection.  Clones can mate and reproduce clone children.  A clone and a souled-human can mate and, again, only reproduce clone children.

Humans have no means to create a soul in another human clone, therefore, human clones have no soul and no concept of right and wrong, no conscience and no compassion.  They have survival instinct and are greatly concerned about their own death, but not the welfare and death of others.

This explains why so many people today have no values, no morals, no ethics and are prone to violence. 

They are more easily programmed through our mind-control type education and military training than are souled-humans with a freewill.  Clones have no freewill, only a sense of survival, and will act accordingly through conditioned behavior.

The eye is the window of the soul.  In the eye of another souled-human you can sense the Light emanating from the soul, the God Spirit within.  As I said earlier, soul or God Spirit within, so there is no God-connection to the eternal Light of Creator Source.  Therefore, there is no the human clone has no spiritual discernment.  The eyes of a human clone may appear dull, blank, hollow, dark, vacant, lifeless, empty with no vibrancy or Light. They have no reaction to or understanding of spiritual energy, concepts or conversation.

Well, the first thing that jumps out at me is that a "person with blank, dead eyes who has no concept of right or wrong, no compassion, no values, no morals, no ethics, and no care about the welfare of others" is a far better description of Donald Trump than it is of Joe Biden.  Be that as it may, the whole protocol for telling apart clones from real people seems pretty... subjective.  Even the website admits that the synthetic humans are just like regular humans, down to the genetic level, even though their science seems a little sketchy in other respects:

Certain tissues extracted from cattle are the starting point.  (This is part of the reason for cattle mutilations.)  The process is an advancement of a process discovered in the late 1950s.  This 1959 experiment was reported in a book in 1968 called The Biological Time Bomb by Gordon Rettray Taylor.  Taylor describes the experiment done in France, "They had extracted DNA from the cells of the khaki Campbells and had injected it into the white Pekins, thinking that just possibly the offspring of the latter might show some character derived from khaki Campbells.  To their astonishment the actual ducks they injected began to change.  Their white feathers darkened, and their necks began to take on the peculiar curve which is a mark of the khaki Campbell."  The scientists working under the auspices of the Rothschilds, (who are directed by Satan himself) developed this process by working at secret breakneck speed. T hey developed an advanced development of the process they discovered with the DNA chicken experiment. By the late 1970’s, synthetic people could be produced by the Illuminati.

So you have to mutilate cattle to get tissue samples instead of just buying a package of ground beef at the grocery store, ducks are the same thing as chickens, the Rothschilds are directed by Satan, and therefore there are bunches of synthetic soulless people walking around.  Got it.

Apparently, though, that's not all.  Not only do we have fake people walking around, but as Trump mentioned in his post some of them are actually robots.  Jimmy Carter was one, for example:

Organic robotoids: This is an "artificial life" form that is created through processes that are totally different than cloning or synthetics.  Organic robotoid technology is being made to make exact as possible copies of important people such as Presidents and some of their staff.  For instance, the Jimmy Carter who came to Portland a few years ago who I stood two feet away from and examined visually was not the Jimmy Carter that had run for President.  On Easter, 1979 the first robotoid model of Jimmy Carter replaced the man Jimmy Carter.  By the time "Carter" was seen by me, they must have been on at least robotoid no. 100.

Myself, I'm surprised that anyone who visually examined a former president of the United States from two feet away wasn't immediately escorted from the premises by men in dark suits and sunglasses.  But I guess he was lucky.  Or maybe it was just because the Dark Suits knew that if something happened to Jimmy Carter Version 100, they could always replace him with Version 101.

The site provides hours of bizarre exploration, wherein we find out that not only are Joe Biden and Brad Pitt synthetic humans, or clones, or robotoids, or whatnot, so are:

• Cameron Diaz
• Bob Dylan
• Angelina Jolie (figures, since Brad is, right?)
• Christina Aguilera
• Beyoncé (I thought she was an Illuminatus herself?  C'mon, people, get your story straight)
• Eddie Murphy
• Courteney Cox
• David Icke

The last one made me choke-snort coffee all over my computer, because David Icke is one of the people who is always supposedly blowing the whistle on the Illuminati and the New World Order and the Bilderburg Group and what-have-you, and now we learn that he's not really David Icke, he's someone else who not only looks just like David Icke, but also has David Icke's loony views of how the world works?  Evidently so:

David Icke got replaced 2007 by a synthetic clone.  We... did a lot of mathematic facial geometry analysis and other stuff.  Also we found out that the new David Icke has no birthmarks anymore in his face, a lot bigger shoulders and his hands have a different geometry.  Also the way he use his muscles of the face, shoulders and hands, even the fingers and mostly the eyes and the bigger nose with its different form is a proof.  Also the different color of his skin.  Its [sic] a very fine difference of the color.  Also the distance between body and head is now different.  Also his psychology while talking.  We did a very deep analysis of a lot famous people and we are experts for doing this.  We work all together and are as objective as possible.

Well, there you are, then. They did lots of "stuff" and found out that (amongst other things) David Icke's head has moved farther away from his body.  Plus, they say they're being objective, so pretty much q.e.d., as far as I can tell.  You can see why Trump found this such an appealing idea.  I mean, who wouldn't?  The logic is inescapable.

So, anyway, that's today's dip in the deep end of the pool, thanks to yet another brilliant missive from the Leader of the Free World.  Me, I'm going to get a second cup of coffee, so I can appear less vacant and hollow-eyed, and hopefully trick more people into thinking I'm actually Gordon.  Well, I am Gordon, but not the real Gordon.  I'm the Gordon who looks like Gordon.

Never mind.  You know what I mean.  At least I'm sure I'll fool the Democrats.

Moon madness

There's a general rule that once a lie gets out into wide circulation, trying to replace it with the truth is damn near impossible.  We've seen lots of examples of that here at Skeptophilia -- chemtrails, the HAARP conspiracy, the whole "vaccines cause autism" thing, and "Pizzagate" come to mind immediately.  No matter how thoroughly these are debunked, they never seem to die.  In fact, legislation in my home state of Louisiana to "ban chemtrails" just passed in the state House of Representatives.  It was sponsored by Kim Landry Coates (R-Ponchatoula).  When Coates was asked what chemicals were allegedly in these "chemtrails," she responded, I shit you not, "Barium.  There is a few, some with long words that I can’t pronounce."

Which illustrates another general principle, which is that there is no intelligence criterion for being elected to public office.

This is not a new problem, much as the Trump administration has cornered the market on egregious lies in the last few years.  Humans have always been credulous, and once convinced of a lie, unconvincing someone is the very definition of an uphill struggle.  Take, for example, the Great Moon Hoax of 1835.

In August of 1835, writers at The Sun (a New York City newspaper, not the British tabloid of the same name) dreamed up a scheme to boost circulation -- a hoax article (complete with illustrations) claiming that astronomers had spotted life on the Moon.  The discovery, they said, was made using "an immense telescope of an entirely new principle," with a lens that measured eight meters in diameter and weighed seven metric tons.  Using this, the researchers were able to see living things on the Moon, including bat-winged humanoids the scientists called Vespertilio-Homo, as well as single-horned goats, miniature zebras, and bipedal tailless beavers.

The Moon, they said, was also covered with active volcanoes, but the beings there used them as power sources, allowing the Vespertilio-Homo to live in large thriving cities:

[Image is in the Public Domain]

And just like today, when Trump invariably precedes his lies with "my advisors are telling me" or "I've heard from reputable sources," The Sun gave this "research" an attribution -- but they boldly named names.  The source, they said, was one Andrew Grant (who was fictitious), the assistant and dear friend of John Herschel (who very much was not).

John Herschel was a highly respected British astronomer, mathematician, chemist, and polymath, son of William Herschel (who discovered Uranus).  The younger Herschel had established a name for himself in planetary astronomy, and in fact had studied and named seven of the moons of Saturn and four of the moons of Uranus.  So his was a canny choice by The Sun -- it gave automatic legitimacy to the article's contents.

It took over a month for the entire story to come unraveled.  Pressed by scientifically-literate readers to show them the amazing telescope, they responded that it had sadly been destroyed in a fire -- the enormous lens's capacity for "concentrating the rays of light" had proved its own undoing, and completely burned down the observatory where it resided.  It was only when Herschel was asked about the research and said he knew nothing about it that the owners of The Sun were confronted, and finally -- reluctantly -- they admitted it had been a hoax all along.

Interestingly, though, they never published an actual retraction of the articles.  Five years later, one of The Sun's reporters, Richard Adams Locke, admitted he'd written the story, but said he'd done it as satire, to "show how science can be and is influenced by the thoughts of religion."  Which seems like a pretty flimsy claim to me.  I think the great likelihood is that it was a publicity stunt to boost circulation, and as such, it worked brilliantly -- The Sun became one of the bestselling newspapers in the United States, and survived until 1950.

The lie also had astonishing longevity.  Even after the owners of The Sun admitted it had all been a hoax -- there were no bat-creatures, no miniature zebras, no bipedal beavers -- people still claimed it was true.  The admission, not the original story, had been the hoax, they said, and The Sun's owners had only changed course because they thought the American people couldn't handle how weird the truth was.  Years later, poor John Herschel was still being asked about the bat-winged Moon men and his role in discovering them.

My dad used to say that trying to clean up the results of a lie was about as easy as getting toothpaste back into the tube.  And the Great Moon Hoax of 1835 illustrates another dark truth; the fact that getting suckered by an attractive lie can cause you to swing all the way over into cynicism.  Some readers who found out about the hoax concluded that nothing in the newspaper could be trusted.  It's like Mark Twain's observation: "You can learn too much from experience.  A cat that sits on a hot stove will never sit on a hot stove again, but it probably won't sit on a cool one, either."

Cynicism, as I've pointed out more than once, is no smarter than gullibility.  It's just as lazy to conclude that everyone is lying to you as it is to believe that no one is.  But it's a tragedy when the media itself is the source of the lies.  While I can't condone cynicism about the media, I do understand it.  Daniel Patrick Moynihan famously said, "You are entitled to your own opinions, but you are not entitled to your own facts."  Which is true enough, but that presupposes we can actually find out what the facts are.  And when the sources you are supposed to be able to trust are themselves lying to you, it creates a catch-22 that I'm damned if I know how to get out of.

Ministry of propaganda

Is it too much to ask that the Trump administration simply tells the damn truth?

That's all I ask.  Just stop lying.  I'm fine with having differences of opinion over policy.  For example, claiming that unhooking from fossil fuels and switching to renewable energy would be an unreasonable burden on our economy is not the same thing as saying climate change isn't occurring.

The first is a policy question we could discuss, and perhaps, come to consensus about.  The second is a lie.  And as long as you're simply lying about the facts, there is no discussion to be had.

Take, for example, the person who would have to be included in the top five most dangerous members of this regime; Health and Human Services Secretary Robert F. Kennedy Jr.  He is an anti-science ideologue of the worst sort, and because of him the CDC is now limiting access to COVID-19 vaccinations and canceling funding for this year's flu vaccine -- including the potentially pandemic bird flu.

All part of his "Make America Healthy Again" campaign.  Because horrible policies are just fine as long as you give them a snappy name, right?

Of course right.

It doesn't end with anti-vaxx nonsense, either.  Just this week, RFK stated that gender-affirming care for individuals with gender dysphoria should be discontinued -- once again, flying in the face of scientific study after scientific study.  Ignore the science, he says; instead, listen to the directives from the government.

And what is the government suggesting instead?

Why, "conversion therapy."

Yep, the same thing that was touted to "cure homosexuality," and which (once again) study after study has shown to be (1) ineffective, and (2) psychologically damaging.  RFK's letter to healthcare providers states that they should uphold their oaths to "do no harm" by following a strategy that has been conclusively shown to do harm.

Then there's his report on "gold-standard" scientific research that allegedly supports his viewpoints on holistic health and the sins of Big Pharma -- which contains (1) dozens of citations that were identified as mischaracterized by the actual authors themselves, and (2) at least seven citations for studies that appear to be nonexistent.  In other words, RFK pulled the middle-school bibliography-boosting stunt of making up plausible-looking sources, taking others and claiming they said things they didn't actually say, and hoping like hell no one notices.

Well, someone noticed.  But did he retract the report and apologize?

Ha.  Of course he didn't.  This administration never apologizes for anything.  Confronted by their own blatant lies, they just double down, stamping their feet and saying "it is so true!", and rely on the fact that their supporters have no scientific training and very short memories.

Oh, and also this week, he promised a ban on federally-funded medical researchers from publishing in top-flight journals like Lancet, The New England Journal of Medicine, and Journal of the American Medical Association.  Why?  Because they're "corrupt."  Instead, he wants them to publish in a journal he's going to run, after vetting researchers as "good, legitimate scientists" -- meaning, of course, that they agree with him.

Look, it's not (as I've said many times before) that I'm unaware of the problems inherent in the American medical system.  My wife is a nurse, so I hear about a lot of it from her, and I've witnessed the misery that friends and family members have gone through trying to navigate their way through predatory insurance companies, inefficient and understaffed medical care providers, and ridiculously overpriced pharmaceuticals.  I have one friend who's had a ton of chronic health problems, and has gone through the wringer with misprescribed medications and unmanaged side effects.

But RFK is making a bad situation much, much worse.  His outright lies and barrage of unapologetic misinformation are going to kill people, pure and simple.  But my guess is that no one is going to pull on the reins, because we can't stop a program called "Make America Healthy Again," right?  What, do you want to Make America Unhealthy Again?

Honestly, I put the lion's share of the blame here on the members of Congress who voted to approve his appointment to the Cabinet.  It's not like his views were some kind of a secret; we knew about incidents like his lies about the measles vaccine resulting in an epidemic in Samoa that killed eighty people.  The man goes way past "unqualified," into the territory of "outright dangerous."  He should never have been appointed, much less confirmed.

So this is episode #352,981 of "We Tried To Warn You."  And now we're seeing the results of that dreadful lapse of civic responsibility on the part of our elected officials.

All I can say is that insofar as you can, take care of your health.  Take precautions, get the vaccines that are available, and educate yourself using actual scientific research and not Ministry of Propaganda doublespeak.  Even so, my suspicion is that it's going to be a rough few years.

Sundrops

It's always a little surprising to find out that phenomena that are (figuratively speaking) right in our own neighborhood are still a mystery.

One example is the temperature of the solar corona.  We aren't usually aware of the solar corona -- its eerie pinkish luminescence is ordinarily lost in the much brighter radiance of the solar photosphere.  But it becomes visible during a total solar eclipse:

The total solar eclipse of 21 August 2017, photographed by Giuseppe Donatiello [Image is in the Public Domain]

The core of the Sun is estimated to have a temperature of about 15,700,000 K; that heat energy reaches the surface (largely through convection) and then is lost to space.  The outer layer, or photosphere -- the part we can see from Earth on a sunny day -- is around 5,800 K, which is still pretty hot.  But the wispy corona that surrounds the sun is around 5,000,000 K.

But how can that be?  Since, presumably, it's obtaining its heat from the photosphere, how can it be hotter than its own heat source?  Doesn't that break the Second Law of Thermodynamics, which says (amongst other things) that heat energy only flows from hotter objects to cooler ones?

Well, one thing to keep in mind -- not that it solves the mystery, or anything, but at least to get the facts straight -- is that temperature and heat energy are not the same thing, although they are clearly related.  Temperature is a measure of the kinetic energy of molecules, and that depends on more than their heat energy content, but factors like what the material is made of and how densely packed it is.  When I explained this to my students, I used the example of a pot of water heated to boiling (100 C) and an oven heated to 100 C (212 F).  Now imagine putting one hand in the pot of water and the other in the oven for five seconds.

Wouldn't be the same, would it?  Water holds a great deal more heat energy than air does -- at the same temperature.

So the five million Kelvin temperature of the corona is a measure of how fast the molecules are moving.  But still -- something is giving them that much kinetic energy.  So how's it all work?

Now, a new study from the National Solar Observatory has provided one piece of the puzzle -- but in the process, raised more questions.

It appears that packets of extremely hot material are being launched from the surface of the Sun.  When they get away from the turbulent photosphere, the pressure drops, and these "heat bombs" explode, releasing their energy into the corona.  The cooled plasma then recondenses and falls back into the Sun as "coronal raindrops."

Raindrops twenty kilometers wide.

So at least part of the answer is that this launching of plasma from the surface is acting as a heat energy transporter.  But how this process sustains the coronal temperature at a (much) higher value than the surface of the Sun below it is still mysterious, as is the connection between coronal rain and larger-scale phenomena like sunspots, solar prominences, and coronal mass ejections (including the scarily enormous Miyake events).

Like the best science, this study suggests an explanation for some facets of the phenomenon, but leaves a great deal of room for further study.  And points out the fact that we still have many mysteries left to ponder, including about our closest star, something we see every clear day.  Even the familiar can lead us into deep waters fast -- if you ask the right questions.

Good friends

It's a point I've made before, but it's worth saying again: we queer folks are not "pushing our lifestyle in other people's faces" simply because we'd like (1) some acknowledgement that we exist, and (2) the same rights and respect that everyone else gets automatically.

In the current regime here in the United States there are places of employment where people in same-sex relationships aren't allowed to display photographs of their partners, or even mention them.  "It's okay, I guess, as long as no one knows who you actually are," is the general gist.  There seems to be a real fear that just being around openly queer people will cause straight men and women to switch teams.  But really -- do you honestly think that's how all this works?  I mean, think about it.  Some one hundred percent straight guy finds out his coworker is gay, and suddenly gets this dazed look on his face and says, "I shall go out and kiss a man immediately"?  Seriously?

After all, it's not like it works the other way, is it?  As a teenager I was exposed to dozens, probably hundreds, of books, movies, and television shows depicting couples in straight relationships, and not a single one about queer people, and I turned out queer anyhow.  Funny thing, that.

Almost like it's inborn and hardwired, or something.

The result of this mindset is that we not only have to deal with out-and-out homophobia, but a whole array of attitudes that don't wish us active harm, but just would prefer it if we were invisible.  Take, for example, the article about a monument built by Alexander the Great for his lover Hephaestion I just stumbled on a couple of days ago.

There, I said it, didn't I?  They were lovers.  Alexander was either gay or bisexual, and he was deeply in love with Hephaestion.  They were described as "one soul inhabiting two bodies" by Aristotle, who knew both men well.  Their relationship was compared more than once to that of Achilles and Patroclus, which is not exactly a chaste allusion.  Plutarch recounts that they paid a visit to the tombs of the two Greek heroes, where Alexander garlanded Achilles's tomb and Hephaestion Patroclus's -- then ran a race, naked, in their honor.

Totally straight behavior, that, right?

Of course right.

Then there's the incident -- also related by Plutarch -- where Alexander allowed Hephaestion to read something he'd written but wanted to remain secret, and to symbolize this touched his signet ring to Hephaestion's lips.  The moment has been depicted many times in art:

When Hephaestion died suddenly of what was probably typhus in Ecbatana (now in Iran) in 324 B.C.E., Alexander was inconsolable.  The historian Arrian says that upon seeing Hephaestion dead, Alexander "flung himself on the body of his friend and lay there nearly all day long in tears, and refused to be parted from him until he was dragged away by force by his companions."

Oh, what good friends they were.

Alexander commissioned a massive tomb in Hephaestion's honor at Amphipolis in Macedonia -- the Kastas Tomb -- which is the subject of the article I linked above.  [Nota bene: Alexander didn't live to see it completed; he died himself the following year of uncertain causes.]  The tomb is filled with symbolic representations of the spiritual and physical bonds of love, and the hope for being reunited in the afterlife.

Despite all this, when the two were depicted as lovers in the 2004 film Alexander, there was an outcry that "Oliver Stone turned Alexander the Great gay!" and how dare they depict this heroic figure as perhaps having same-sex attraction.  It's apparently hard for some people to imagine that a guy could be a brilliant king and military leader, and still be queer. 

What's striking, though, is that there's a much more subtle aspect of this, beyond the predictable snarling from the overt homophobes.  What I noticed about the archaeology article was that never once was it explicitly mentioned that Alexander and Hephaestion might have had a sexual relationship.  Throughout, they're referred to as "friends" or "confidants" or "companions;" the closest the writer comes is saying that they clearly had a "strong emotional bond" and that the tomb is a "tribute to love and loyalty."

Why the hell are they afraid of saying it?  I mean, if you want to err on the side of caution, at least admit that it was possible.

Apparently even that is a bridge too far.

It's all part and parcel of the "don't ask, don't tell" mentality, isn't it?  "We're fine as long as we can pretend you queer people don't exist and never have."  Well, allow me to point out that this, too, is homophobia.  I spent decades in the closet out of fear and shame from this kind of thinking.  And, straight readers, if you don't think this is damaging, I want you to imagine what it would be like if your employer told you that you must never mention you are in an opposite-sex relationship.  Oh, it's fine, as long as no one knows.  Don't bring your spouse or significant other to the company picnic, don't be seen holding hands in public, don't have a photograph of you as a couple on your desk.

Now imagine if your government was saying the same thing.

Yes, I know that there are places in the world that have it much worse, where being openly queer can get you imprisoned, tortured, or executed.  But we here in the west need to keep in mind that there are ways to oppress people that are subtler and more insidious.  How is this sort of thing any different from putting Jews, Romani, and Blacks (just to name three of many groups this has happened to) in a position where they feel like they have to hide who they are in order to "pass?"

If you think that's wrong, then so is this.

I'm out publicly, so it's far too late for me to hide even if I wanted to.  But honestly -- I wouldn't go back to being invisible even if I could.  All those terrified years did a lot of damage to me emotionally, damage I doubt I'll ever completely heal from (and that's not even counting the regrets over the richer, more honest life I could have had).  To make it clear, I'm not unhappy where I am today; despite all I've been through, I've arrived at a good place.

I just wish I'd had a happier past, is all.

And I will continue to speak out against this kind of straightwashing.  Because it not only is an inaccurate view of history, but does damage to queer people right now.  I've often wondered if there had been honest, positive depictions of LGBTQ+ people in the fiction and nonfiction I read as a teen, maybe I'd have come out as bi when I realized it (age fifteen or so) rather than hiding for another forty years.  Maybe I still wouldn't have, I dunno; southern Louisiana in the seventies wasn't exactly a congenial place for people who were different, and I'm honestly not a very brave person.

But if by speaking out, I can help other people who are still in the closet -- well, don't expect me to shut up.  It's the least I can do after maintaining my own personal silence for four very long decades.
