The second Sun

I know the universe can be a weird place sometimes, but... let's follow Carl Sagan's dictum of looking for a normal and natural explanation for things before jumping to a paranormal or supernatural one, mmmkay?

The reason this comes up is because of a discussion I saw online about the strange phenomenon of a "double Sun" -- when there appears to be a split view of the Sun (or, sometimes, a smaller "second Sun" near the main one).  The first clue that this is a completely natural (albeit odd-looking) occurrence is that it always happens when (1) the sky is hazy, and (2) when the Sun is near the horizon.  It turns out to be caused by the Sun's light refracting off particles of ice or smoke in the upper atmosphere, creating an ephemeral double image.

It is, in fact, simply an optical illusion.

One of the commenters, evidently a science type, gave a measured and reasonable response explaining light refraction, and that resulted in everyone basically going, "Oh, that's cool!  An interesting atmospheric phenomenon!  Thank you for the scientific explanation!"

Ha!  I'm lying.  Of course that's not how people responded.  He was immediately shouted down by about a hundred other folks, who had "explanations" like the following.  Spelling and grammar are exactly as written, because you can only add [sic] so many times:

• It’s just more proof that the Earth is flat.  We’ve been viewing a computer CGI simulation since the late 1800s, and it has just been a matter of time before we start seeing glitches in the man’s software.

• Is it nibiru?  I've read planet x?  Is it a sun like star or what?  I'm so confused.

• It has been photographed before, from Seattle to Wisconsin.  NASA has known about the approach of Nibiru, the Destroyer, Planet X or the countless other names it is known by, including Wormwoof, which it is known by in the bible.  It is an entire star system travelling on an elliptical orbit towards our earth.  It has its own Sun (which you are seeing) and several planets that travel with it.  All the people want to know why can’t you see it.  The answer is because it’s a dead brown star that can only be seen in the infra red spectrum.  The only 2 places that have a black light telescope is in Antarctica and the Vatican.  Go figure.

• If you don’t mind, I will actually give you a serious reply, depending on what you believe in depending on what you think is possible and aside from that, depending on what frequency you operate at you’re able to see in those things, I’ve heard a lot from people who are a lot smarter than me that by 2027 the two suns will be completely visible as well as open contact.  I don’t care if I’m labeled crazy I don’t channel.

• Idk what any of this can or will mean for us here, but boys and girls I don't think the comet in our orbit, that they say should remain visible to the naked eye, but only while facing due West, and get this....only during, or immediately after the sunset will it appear near the Sun, I don't think that's what they are telling us it is.  Is this the reason all these billionaires have been building massive underground bunkers suddenly this past year?

• Trump the Antichrist is here and two suns is the beginning of the end.  In many apocalyptic and religious interpretations, the imagery of “two suns crossing in the sky” is often associated with the arrival of the Antichrist, signifying a significant and ominous event that marks the beginning of the end times, often interpreted as a sign of a false messiah or a powerful evil force emerging into the world, e.g. Trump and Musk.

• There is a second sun behind our sun but we can never see it because it stays behind the sun.  It’s gravitational balanced by the tiny black hole on the other side of our moon that we can’t see either.  Every 276 years in June the moon’s black hole and the second son have a tilting wobble and the second sun becomes visible for a few minutes in a small viewing zone across the northern hemisphere.  Behind the second sun there are a few more things that we can’t see, like second Jupiter.

A few thoughts about all that.

• What the actual fuck?

• Okay, I can see Trump as the Antichrist, given that he embodies all Seven Deadly Sins in one individual.  But somehow I don't think even his level of evil can make two Suns appear in the sky.

• If it's only visible for a few minutes every 276 years, it was pretty lucky the dude got a snapshot of it, wasn't it?

• So, Nibiru is en vogue again, eh?  Last I heard of Nibiru was about ten years ago, and I figured it had become passé, replaced by far more believable claims like targeted weather modification and 5G mind control and Jewish space lasers.

• If I've never seen a "second Sun," it's because I'm "operating on the wrong frequency?"  I didn't know humans were like radios, and came equipped with a frequency dial.  That's pretty awesome.  Maybe if mine is set right I can tune into the BBC.

• Only Antarctica and the Vatican have "black light telescopes"?  I'm trying to come up with some kind of clever response to this, but... nope, I got nothin'.

• If I ever get another pit bull, I'm gonna name him "Wormwoof."

• At the risk of repeating myself, what the actual fuck?

What astounds me about all of this is how many people seem to gravitate toward this sort of nonsense instead of looking first for a rational explanation.  It's not like the science in this case is hard to understand, or even hard to find; the website of the National Radio Astronomy Observatory posted a perfectly good explanation that shows up on the first page of a Google search for "double Sun."

But loony claims like Nibiru and dead brown stars and second Jupiters and simulation glitches are, apparently, more attractive.  Is it because it makes the universe seem weirder and cooler?  Or is it the appeal of "seeing through a coverup" by scientists or the government or whatnot?

It's always seemed to me that the scientific explanations of what we observe are plenty cool enough, and some of them -- like quantum physics -- plenty weird enough.  Why do so many people need to add extra layers of wackiness onto things?

I'll end with another quote from Carl Sagan, which I think sums things up nicely: "For me, it is far better to grasp the universe as it really is than to persist in delusion, however satisfying and reassuring."

Dark days

I'm going to propose a new law, in the vein of Murphy's Law ("If it can go wrong, it will"), Betteridge's Law ("If a headline ends in a question mark, the answer is 'no'"), and Poe's Law ("A sufficiently well-done satire is indistinguishable from the real thing"): "If a statement begins with, 'Scientists claim...' without mentioning any specific scientists, it's completely made up."

I ran into an excellent (by which I mean "ridiculous") example of that over at the site Anomalien just yesterday, called "The Mysterious Phenomenon of the Onset of Sudden Darkness."  The article, which is (as advertised) about times when darkness suddenly fell during the day for no apparent reason, gets off to a great start by citing the Bible (specifically the darkness sent by God in the Book of Exodus to punish the Egyptians for keeping Moses et al. in slavery), because that's clearly admissible as hard evidence.  "Scientists," we are told, "are seriously concerned about this phenomenon."

I have spoken with a great many scientists over the years, and not a single one of them has voiced any concern about sudden-onset darkness.  Maybe they're keeping it secret because they don't want us laypeople getting scared, or something.

That being said, and even excluding the Pharaonic Plagues, the claim has been around for a while.  One of my favorite books growing up -- I still have my rather battered copy, in fact -- was Strangely Enough, by C. B. Colby, which deals with dozens of weird "Strange But True!" tales.  One of them, called "New England's Darkest Day," describes an event that allegedly occurred on May 19, 1780, in which pitch darkness fell on a sunny day.  Colby writes:

May 19 dawned as bright and clear as usual, except that there appeared to be a haze in the southwest.  (One town history reports that it was raining.)  This haze grew darker, and soon the whole sky was covered with a thick cloud which was traveling northeast rapidly.  It reached the Canadian border by midmorning.  Meanwhile the eastern part of New York, as well as Maine, New Hampshire, Rhode Island, Massachusetts, and Connecticut were becoming darker.

By one o'clock some sections were so dark that white paper held a few inches from the eyes couldn't be seen.  It was as dark as a starless night.  Apprehension soon turned to panic.  Schools were dismissed, and lanterns and candles were lighted in homes and along the streets...

That night the darkness continued, and it was noted that by the light of lanterns everything seemed to have a greenish hue.  A full moon, due to rise at nine, did not show until after 1 AM, when it appeared high in the sky and blood-red.  Shortly afterward stars began to appear, and the following morning the sun was as bright as ever, after fourteen hours of the strangest darkness ever to panic staunch New Englanders.

Surprisingly, there's no doubt this actually happened; as Colby states, it's recorded in dozens of town histories.  However, the actual cause isn't anything paranormal.  It was most likely a combination of dense fog and the smoke from a massive forest fire in what is now Algonquin Provincial Park in Ontario, which left evidence in the form of tree ring scars from the late spring of that year, precisely when the "Dark Day" occurred.  And, in fact, Colby conveniently doesn't mention that there are also reports in town histories that "the air smelled like soot" and after the sky cleared, some places (especially in New Hampshire) had layers of ash on the ground up to fifteen centimeters deep.

Kind of blows away the mystery, doesn't it?

The Anomalien article isn't even on as firm a ground as Colby is.  The majority of their accounts are single-person anecdotes; even the ones that aren't have very little going for them.  Take, for example, the case in Louisville, Kentucky, which they say is so certain "it's almost become a textbook" [sic].  On March 7, 1911, they say, a "viscous darkness" fell upon the entire city, lasting for an hour and resulting in massive panic.

Funny that such a strange, widespread, and terrifying event merited zero mention in the Louisville newspaper that came out only four days later.  You'd think it'd have been headline news.

That doesn't stop the folks at Anomalien from attributing the phenomenon to you-know-who:

Is it all aliens to be blamed?  Researchers... believe that unexpected pitch darkness occurs in the event of a violation of the integrity of space.  At such moments, it is possible to penetrate both into different dimensions and worlds, and out of them...  

Some researchers believe that the phenomenon of sudden pitch darkness is associated with the presence on earth of creatures, unknown to science, with supernatural abilities.  All these cryptids and other strange creatures enter our world through the corridors of pitch darkness.  And they seem to be more familiar with this phenomenon than we are.  They know when this passage will open, and they use it.  Only they do not immediately disappear along with the darkness, but wait for the next opportunity to return to their world.

Oh?  "Researchers believe that," do they?  I'll be waiting for the paper in Science.

Anyhow, there you have it.  Bonnet's Law in action.  I'm just as happy that the claim is nonsense; the sun's out right now, and I'm hoping it stays that way.  It's gloomy enough around here in early spring without aliens and cryptids and whatnot opening dimensional portals and creating "corridors of pitch darkness."  Plus, having creatures ("unknown to science, with supernatural abilities") bumbling about in the dark would freak out my dog, who is -- no offense to him intended, he's a Very Good Boy -- a great big coward.

So let's just keep the lights on, shall we?  Thanks.

Illuminating Hessdalen

In his wonderful poem/performance piece Storm, Tim Minchin said: "Throughout history, every mystery ever solved has turned out to be 'not magic'."

As I've pointed out many times here before, it's not that I'm saying any of the thus-far-classified-as "out there beliefs" are impossible; it's that if they actually do exist, they should be accessible to scientific inquiry.  Auras, qi, chakras?  Demonstrate they're detectable by something other than a subjective viewer.  Hauntings?  Ditto.  Cryptids of various shapes and descriptions?  Give me something analyzable other than blurry photos and anecdotal eyewitness accounts.  Psychic abilities?  Show they work under controlled conditions.  

Interestingly, there was just an article in The Skeptic asserting that parapsychology has grown to the point that it deserves the title of science rather than pseudoscience.  I'm sure that the author, Chris French, professor of psychology at the University of London, will receive some blowback from this essay, as will The Skeptic in general for publishing it; but I agree with his central thesis, which is that parapsychological claims stand and fall on exactly the same basis as scientific claims do -- evidence.

And, as Minchin says, if a supernatural explanation turns out to be scientifically demonstrable, then it's no longer supernatural, is it?  It's just natural.  After that, it can be studied by the methods of science, just like every other feature of our weird, wonderful, amazingly complex universe.

What brings this up is a recent paper in Meteorology and Atmospheric Physics that considered the odd phenomenon of the "Hessdalen Lights" which occurs in a valley in central Norway, wherein people report seeing free-floating balls of light.  I'd written about the Hessdalen Lights (and various other accounts of lights in the sky) back in 2017, and described it as follows:

The Hessdalen Lights have been seen since the 1940s in the valley of Hessdalen in Norway.  They're stationary, bright white or yellow lights, floating above the ground, sometimes remaining visible for over an hour.  With such a cooperative phenomenon, you would think it would be easily explained; but despite the efforts of scientists, who have been studying the Hessdalen Lights for decades, there is yet to be a convincing explanation.  Hypotheses abound: that it is the combustion of dust from the valley floor; that it is a stable plasma, ionized by the decay of radon from minerals in the valley; or even that it is an electrical discharge from piezoelectric compression of quartz crystals in the underlying rock.  None of these is completely convincing, and the Hessdalen Lights remain one of the most puzzling natural phenomena I know of.

The lack of a convincing explanation opens the door to all sorts of wild speculation, and those abound -- ghosts, aliens, portals in time and space, you name it.  

Photograph of the Hessdalen Lights

As usual, my fallback position was, "I may not know what the scientific explanation is, but I'm certain that one exists."  Given how many times this phenomenon has been reported and photographed, it seemed pretty likely that it wasn't a hoax, or even misattributing it to something purely prosaic (like Neil deGrasse Tyson's story of a cop who was driving down a winding country road, chasing a "weird light in the sky" -- which turned out to be the planet Venus).  So accepting that the Hessdalen Lights actually occur as advertised, what the hell are they?

Much was my delight when I ran across the recent paper, by atmospheric chemist Gerson Paiva of Federal University Pernambuco (Brazil), which seems to have solved the mystery, using...

... wait for it...

... science.

Here's what Paiva writes:

Hessdalen lights are unusual, free-floating light balls presenting different shapes and light colors, observed in the Hessdalen valley in rural central Norway.  In this work, it is shown that these ghostly light balls are produced by an electrically active inversion layer above Hessdalen valley during geomagnetic storms.  Puzzling geometric shapes and energy content observed in the HL phenomenon may be explained through a little-known solution of Maxwell’s equations to electric (and magnetic) field lines: they can form loops in a finite space...  “Natural battery”, aerosols and global atmospheric electric circuits may play a crucial role for the electrification of the temperature inversion layers.

Now, I hasten to add that I don't know if Paiva's explanation is right.  But that's the other great thing about science; it's falsifiable.  When a researcher publishes something like this, it's immediately analyzed and taken to pieces by other experts in the field.  Unlike us fiction writers, who basically want everyone to read our writing and tell us how awesome it is, scientists are looking for rigorous criticism; they want their colleagues to try to tear it down, to see if their analysis is robust enough to withstand attempts to refute it.  So time will tell if Paiva has found the answer to this enduring mystery of atmospheric science.

But even if he hasn't, I'd bet cold hard cash that like Tim Minchin said, the answer will still turn out to be "not magic."

Mathematics tends to sort people into two categories -- those who revel in it and those who detest it.  I lucked out in college to have a phenomenal calculus teacher who instilled in me a love for math that I still have today, and even though I'm far from an expert mathematician, I truly enjoy considering some of the abstruse corners of the theory of numbers.

One of the weirdest of all of the mathematical discoveries is Euler's Equation, which links five of the most important and well-known numbers -- π (the ratio between a circle's circumference and its diameter), e (the root of the natural logarithms), i (the square root of -1, and the foundation of the theory of imaginary and complex numbers), 1, and 0.  

They're related as follows:

Figuring this out took a genius like Leonhard Euler to figure out, and its implications are profound.  Nobel-Prize-winning physicist Richard Feynman called it "the most remarkable formula in mathematics;" nineteenth-century Harvard University professor of mathematics Benjamin Peirce said about Euler's Equation, "it is absolutely paradoxical; we cannot understand it, and we don't know what it means, but we have proved it, and therefore we know it must be the truth."

Since Peirce's time mathematicians have gone a long way into probing the depths of this bizarre equation, and that voyage is the subject of David Stipp's wonderful book A Most Elegant Equation: Euler's Formula and the Beauty of Mathematics.  It's fascinating reading for anyone who, like me, is intrigued by the odd properties of numbers, and Stipp has made the intricacies of Euler's Equation accessible to the layperson.  When I first learned about this strange relationship between five well-known numbers when I was in calculus class, my first reaction was, "How the hell can that be true?"  If you'd like the answer to that question -- and a lot of others along the way -- you'll love Stipp's book.

Lights in the Ozarks

I was chatting with a good friend and long-time reader of Skeptophilia about the difficulties of finding topics to write about six days a week, and right off the bat she came up with one I'd never heard of.

She's another novelist, so I probably shouldn't have been surprised that she had heard about local legends in the Ozarks, near her home in northwestern Arkansas.  Her name is K. D. McCrite -- she's a versatile and creative writer, writing children's books, romances, and cozy mysteries, but also (under her pen name Ava Norwood) writes domestic thrillers that'd knock your socks off.

"Have you ever heard of the Joplin Spook Lights?" K. D. asked.

Well, it sounded a bit like a minor league baseball team, but I told her I hadn't.

"It's actually not in Joplin that it happens," she told me.  "It's across the border into Oklahoma, near Quapaw.  But lots of people have seen them.  Lights floating in the sky.  They were reported long before there were any cars and airplanes, so whatever they are, they don't seem to be that."

I was intrigued, of course, and she did a little digging and found some references for me.  It's a pretty peculiar phenomenon, whatever it is.

It was allegedly first noticed by Native Americans during the Trail of Tears, but just about every time something like this comes up you hear that the "Native Americans had legends" corroborating it, so I'm not inclined to give that a lot of credence.  But after that, things get pretty weird, and way harder to dismiss out of hand.

In 1881, a publication came out called The Ozark Spook Light claiming it had been seen repeatedly by locals.  It's a ball of light that hovers over the road, and that it "sways from side to side, like a lantern being carried by some invisible force."  It apparently can be seen on most any dark night, seems impervious to wind and rain, and has even been studied by the Army Corps of Engineers -- still leaving us without an explanation.

Initially I thought it might be ball lightning, but on further research it doesn't seem to fit with the descriptions.  Ball lightning -- itself a verified but unexplained phenomenon -- has several common characteristics, which include sizzling discharge when it nears a metal object, and a (usually loud) explosive finish.

The Joplin Spook Lights, on the other hand, are silent.  They don't seem to be electrical in nature, although that's speculation.  Some have linked the phenomenon to the New Madrid Fault -- one of the only potentially dangerous faults in the middle of the continent -- which in 1811 and 1812 suffered a series of earthquakes that changed the course of the Mississippi River, and which if they occurred today, would have flattened every town within a hundred mile radius.  But that doesn't make a lot of sense to me, because the New Madrid Fault is on the other side of the state, over five hundred kilometers away.

If the New Madrid Fault is causing lights in the sky in Quapaw, Oklahoma, the skies over the town of New Madrid itself should look like Fourth of July fireworks show.

But whatever they are, the Spook Lights are a completely local phenomenon.  K. D. put me in touch with a friend of hers who lives near where they're regularly seen, and in fact, has seen them herself, as had her husband.  Here's what she had to say:

I’ve seen it a handful of times over the years.  My first husband saw it up close and personal when he was a teenager.  He said it was a common pastime to hang out there.  I believe it must have been more active and brighter then, which would have been late forties, early fifties, if I’m figuring the time right.

He said he sat on the hood of his car and read a comic book from the light it projected.  It would come up close and sometimes bounce on the top of the cars in front of him.  He said it would split into two, three, four lights, and some were different colors.  Not bright but subtly different shades.  I imagined it like a pale prism.  I don’t know if that’s what it was.  I think he did say it would sometimes be a pale red.

My own experiences were less exciting but they did give me chills a time or two.  I have seen it divide and bounce in the tree tops.  It has seemed to diminish in size and brightness over the years.  I haven’t heard of anyone seeing it in years but maybe people have lost interest.  Too much else to do these days.  The last time I was there was around 2000, 2001.  My husband and I went down with some friends, but that time we didn’t see it at all.

Pretty creepy stuff.  I don't know that if I'd been there and seen spectral lights bouncing off the hoods of cars, I would have been calm enough to sit there and read a comic book.  Although I'm a skeptic and a scientist, I'm also a great big coward, and I suspect if I were on a lonely country road at night and saw weird lights in the sky, I'd either faint or else wet my pants.

Possibly both.

Be that as it may, the lights are still seen today (although perhaps less frequently, as K. D.'s friend mentioned).  In 2016, three friends went investigating, and caught the Spook Lights on film (they call them the "Hornet Spook Lights," after the nearby town of Hornet, Missouri, six miles southwest of Joplin, but it's the same local phenomenon by a different name).  The video they took is strangely convincing -- if you're as impatient as I am, though, you might want to advance it to 9:30 and skip all the introductory conversation.  But the people filming it point out other flashes as distant billboard lights or car headlights, and what they say are the Spook Lights are definitely something different.  My feeling after watching the video is that whatever the three guys captured on video, it wasn't some kind of elaborate hoax.

In any case, the Spook Lights remain unexplained.  Apparently they're one of the best-documented "lights in the sky" in the world, which makes me wonder why I hadn't run across it till now.  I'd still put money on there being a natural explanation, but despite investigation, no one -- including the Army Corps of Engineers -- has been able to figure out what it might be.

So thanks to K. D. and her friend for putting me onto this.  It's certainly a curious phenomenon.  I think maybe next time I'm in the Ozarks (I go there every year for my publisher's annual authors' retreat), I might just head up to Quapaw and see what I can see.  I'll have my camera at the ready, and will certainly report anything I see here.

I'll also have a change of underwear at the ready.  You can't be too careful.
