Knockin' on heaven's door

It's been awhile since we've have a truly goofy claim to consider, so to take a brief diversion from more serious issues, today I bring you:

NASA space telescopes have photographed the Celestial City of New Jerusalem, as hath been prophesied in the scriptures.

I wish I was making this up.  The claim appeared on the ultra-fundamentalist site Heaven & Hell, and the post, written by one Samuel M. Wanginjogu, reads like some kind of apocalyptic wet dream.

It opens with a bang.  "Despite new repairs to the Hubble Telescope," Wanginjogu writes, "NASA refuses to release old photos or take new ones of Heaven!"

Imagine that.

He goes on to explain further:
Just days after space shuttle astronauts repaired the Hubble Space Telescope in mid December, the giant lens focused on a star cluster at the edge of the universe – and photographed heaven! 
That’s the word from author and researcher Marcia Masson, who quoted highly placed NASA insiders as having said that the telescope beamed hundreds of photos back to the command center at Goddard Space Flight Center in Greenbelt, Md., on December 26. 
The pictures clearly show a vast white city floating eerily in the blackness of space. 
And the expert quoted NASA sources as saying that the city is definitely Heaven “because life as we know it couldn’t possibly exist in icy, airless space. 
“This is it – this is the proof we’ve been waiting for,” Dr. Masson told reporters. 
“Through an enormous stroke of luck, NASA aimed the Hubble Telescope at precisely the right place at precisely the right time to capture these images on film.  I’m not particularly religious, but I don’t doubt that somebody or something influenced the decision to aim the telescope at that particular area of space.
“Was that someone or something God himself?  Given the vastness of the universe, and all the places NASA could have targeted for study, that would certainly appear to be the case.”
Unsurprisingly, NASA researchers have "declined to comment."

Then we get to see the photograph in question:



After I stopped guffawing, I read further, and I was heartened to see that Wanginjogu is all about thinking critically regarding such claims:
I am not an expert in photography, but if you scrutinize the photo carefully, you find that the city is surrounded by stars if at all it was taken in space...  If the photo is really a space photo, then it could most likely be the Celestial city of God because it is clear that what is in the photograph is not a star, a planet or any other known heavenly body.
Yes!  Surrounded by stars, and not a planet!  The only other possibility, I think you will agree, is that it is the Celestial City of God.

Wanginjogu then goes through some calculations to estimate the size of New Jerusalem:
If an aero plane [sic] passes overhead at night, you are able to see the light emitted by it.  If that aero plane [sic] was to go higher up from the surface of the earth, eventually you won’t be able to see any light from it and that is only after moving a few kilometers up.  This is because of its small size.  Yet our eyes are able to see, without any aid, stars that are millions of light years away.  This is because of their large size. 
The further away an object is from the surface of the earth, then the bigger it needs to be and the more the light it needs to emit for it to be seen from earth.
The city of New Jerusalem is much smaller than most of the stars that you see on the sky.  To be more precise, it is much smaller than our planet earth.  Remember that here we are not talking of the entire heaven where God lives but of the City of New Jerusalem.  The city of New Jerusalem is currently located in heaven.  Of course, heaven is much larger that the city itself.  The photo seems to be of the city itself rather than the entire heaven.
Some solid astrophysics, right there.  He then goes on to use the Book of Revelation to figure out how big the city prophesied therein must be, and from all of this he deduces that the Celestial City must be somewhere within our Solar System for Hubble to have captured the photograph.  He also uses the testimony of one Seneca Sodi, who apparently saw an angel and asked him how far away heaven was, and the angel said, "Not far."

So there you have it.

The best part, though, was when I got about halfway through, and I found out where Wanginjogu got the photograph from.  (Hint: not NASA.)  The photograph, and in fact the entire claim, originated in...

... wait for it...

... The Weekly World News.

Yes, that hallowed purveyor of stories about Elvis sightings, alien abductions, and Kim Kardashian being pregnant with Bigfoot's baby.  Even Wanginjogu seems to realize he's on shaky ground, here, and writes:
This magazine is known to exaggerate stories and to publish some really controversial articles.  However, it also publishes some true stories.  So we cannot trash this story just because it first appeared in The Weekly World News magazine.  It is worthwhile to consider other aspects of the story.
He's right that you can't rule something out because of the source, but this pretty much amounts to something my dad used to say, to wit, "Even stopped clocks are right twice a day."   But suffice it to say that here at Skeptophilia headquarters we have considered other aspects of the story, and it is our firmly-held opinion that to believe this requires that you have a single scoop of butter-brickle ice cream where the rest of us have a brain.

Anyway, there you are.  NASA photographing heaven.  Me, I'm waiting for them to turn the Hubble the other direction, and photograph hell.  Since that's where I'm headed anyway, might as well take a look at the real estate ahead of time.

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

The advancement of technology has opened up ethical questions we've never had to face before, and one of the most difficult is how to handle our sudden ability to edit the genome.

CRISPR-Cas9 is a system for doing what amounts to cut-and-paste editing of DNA, and since its discovery by Emmanuelle Charpentier and Jennifer Doudna, the technique has been refined and given pinpoint precision.  (Charpentier and Doudna won the Nobel Prize in Chemistry last year for their role in developing CRISPR.)

Of course, it generates a host of questions that can be summed up by Ian Malcolm's quote in Jurassic Park, "Your scientists were so preoccupied with whether they could, they didn't stop to think if they should."  If it became possible, should CRISPR be used to treat devastating diseases like cystic fibrosis and sickle-cell anemia?  Most people, I think, would say yes.  But what about disorders that are mere inconveniences -- like nearsightedness?  What about cosmetic traits like hair and eye color?

What about intelligence, behavior, personality?

None of that has been accomplished yet, but it bears keeping in mind that ten years ago, the whole CRISPR gene-editing protocol would have seemed like fringe-y science fiction.  We need to figure this stuff out now -- before it becomes reality.

This is the subject of bioethicist Henry Greely's new book, CRISPR People: The Science and Ethics of Editing Humans.  It considers the thorny questions surrounding not just what we can do, or what we might one day be able to do, but what we should do.

And given how fast science fiction has become reality, it's a book everyone should read... soon.

Picture perfect

Neil deGrasse Tyson once quipped that photographic evidence was no longer reliable because Photoshop probably had an "Add UFO" button.  It's an exercise I like to demonstrate with my Critical Thinking class; after watching a documentary about fake ghost photographs, they have an optional assignment to try to create the most realistic-looking and/or scary UFO, ghost, or other paranormal photograph they can.

The results are so creepy -- and so easy to make, if you have access even to rudimentary digital image modification software -- that the wall of photographs we display afterwards makes a real impact.

"I'll never believe a photograph is real again," one student said in an awed voice while looking at the collection of ghosts, spacecrafts, and Bigfoots.

Mont St. Michel is beautiful, isn't it?  Yes, but the water and the reflection were all added to the image via Photoshop.  [image courtesy of photographer AndrĂ©s Nieto Porras and the Wikimedia Commons]

While that is honestly a bit of an overreaction, it's always best to be on the suspicious side whenever anyone claims a photograph as proof for a claim.  Not only are altered images easy to make -- as a paper just released last week in Cognitive Research: Principles and Implications shows, humans are kind of lousy at differentiated between retouched and unretouched photos.

In "Can People Identify Original and Manipulated Photos of Real-World Scenes?", authors Sophie J. Nightingale, Kimberley A. Wade, and Derrick G. Watson set up a series of tests in which subjects were asked if they could detect digitally-altered photographs that had impossibilities -- shadows pointing the wrong way, geometrical inconsistencies, features missing (such as removing the crosswise structural supports from a suspension bridge) or added (such as tables with extra legs).  They were given ten photographs, some altered and some not, and as much time as they wanted to study them, and then were asked to identify which (if any) had been manipulated, and if so, how.

And people, in general, were terrible at it.  The authors write:
In two separate experiments we have shown, for the first time, that people’s ability to detect manipulated photos of real-world scenes is extremely limited.  Considering the prevalence of manipulated images in the media, on social networking sites, and in other domains, our findings warrant concern about the extent to which people may be frequently fooled in their daily lives.  Furthermore, we did not find any strong evidence to suggest that individual factors, such as having an interest in photography or beliefs about the extent of image manipulation in society, are associated with improved ability to detect or locate manipulations. 
Recall that we looked at two categories of manipulations—implausible and plausible—and we predicted that people would perform better on implausible manipulations because these scenes provide additional evidence that people can use to determine if a photo has been manipulated. Yet the story was not so simple...  [E]ven when subjects correctly identified the implausible photo manipulations, they did not necessarily go on to accurately locate the manipulation.  It is clear that people find it difficult to detect and locate manipulations in real-world photos, regardless of whether those manipulations lead to physically plausible or implausible scenes.
Which, of course, should be enough to give anyone pause.  Our capacity for recognizing when we've been fooled is far poorer than we tend to believe.


And the more sophisticated the digital manipulation software gets, the worse this problem will become.  Early digital photography programs were nothing short of crude, and attempts to mess around with the image always left traces that a discerning eye could see.  But now?  It's telling that a bunch of inexperienced high school students could, in short order, produce images that were absolutely convincing.

Think of how much could be done by people who were experts in digital image modification.

There's even an iPhone app that adds six-pack abs and broader shoulders to your photo.  Wouldn't it be nice if it were this easy in real life?

So we might well be approaching the "Trust Nothing" stance of my student from last year.  I hate to promote cynicism, but honestly, casting a wry eye on any photographic evidence is probably a smart thing place to start.   We're not quite at the point of having an "Add UFO" button -- but it's not far away.

The bear facts

New from the Wishful Thinking Department, we have a woman in Newfoundland who snapped a photograph of what she says is a polar bear praying.

"When I saw it and started taking pictures, I was blown away," says Jessica Andrews, who owns Ocean View Photography.  "I didn't realize I'd taken the picture until I started going through them...  When I edited them, I saw after that he was by the cross.  This is the one that people were commenting on and saying that, 'He's praying,'"

The story and the photo have been shared tens of thousands of times on social media, mostly by people who think that the bear has found Jesus or something.

Without further ado, let's take a look at the photograph in question:


Here's a smattering of responses I've seen since the story first hit:
  • The animals are smarter than us, sometimes.  They have more faith in God than we do.
  • This gives you a look at what it'd be like if Man had never fallen.  Can you imagine the paradise on earth we'd have?
  • Looking toward his Creator.  Like we all should do.
  • Stop right now and kneel down and give thanks.  If the wild beasts can do it, so can you.
  • This little bear knows how to praise Jesus!
Okay, all piety and good intentions aside, can we just establish a couple of things, here?

This is a polar bear.  It is not praying, it is not the tame denizen of "paradise on earth," and it is not giving thanks.  Just because someone captured it in what looks like a kneeling position does not mean that it has "faith in god."

And, for fuck's sake, it is not a "little bear praising Jesus."  This is a huge and dangerous animal that is a member of one of the few species on Earth that will actively stalk, attack, and kill humans for food.  In the next shot Andrews took -- which you can see posted on the link provided above -- the bear has turned and is looking right at her with an expression that seems to say, "Hmm.  She looks kind of tasty."

So maybe before, the bear was saying Grace Before Meals.  I dunno.

I am certainly understanding of our desire to extract inspiration from the natural world.  Hell, I'm a biology teacher; I'm immersed on a daily basis in the amazing, wonderful world of living things that we share the planet with.  But my awe is tempered by a very certain knowledge that the other species around us are, by and large, completely indifferent to us, our social and cultural conventions, and so on.  Any time we impress upon non-human species some sort of human intention -- courage and majesty in a howling wolf, freedom in an eagle, sneakiness and cunning in a weasel, and so on -- we're on seriously shaky ground.  Whatever sort of emotional state other species exist in, it is almost certain to be pretty different than anything we experience.

Myself, I'd rather learn as much as I can about the living things around me, and experience the wonder and complexity of the Earth through actual knowledge and understanding than to settle for imposing my flawed human interpretations on what the animals around me are doing.  It's more honest, and in the long run, it is way cooler.

On the other hand, I'm absolutely convinced that my dog understood every word I was saying this morning when I explained to him why I wasn't going to give him a second bowl full of dog chow.  So I guess it's all a matter of what you choose to accept.

The Phoenix devil

At present I've been sent a link five times to a claim that someone near Phoenix, Arizona took a photograph of Satan.

Without further ado, let's take a look at the photo:


A couple of the people who sent it to me appended messages along the lines of, "Hoo boy.  Look at what people are claiming now."  Two, however, had more noteworthy commentary, which I reproduce in toto below.

Photo submitter #1:
You like to scoff about the evil in the world, and claim that our souls aren't in peril.  Satan walks among us.  Unbelievers like you will be the first to be dragged to Hell.
Photo submitter #2:
People like Mr. Skeptic doubt evidence for the supernatural when its [sic] right in front of your face.  I wonder what would happen if you saw this with your own eyes.  Would you keep doubting then?  It's easy for Armchair Skeptics to sit in their living rooms and say no, but as soon as you go out in the world you learn that its [sic] not that simple.
Well, predictably, I'm not impressed.  To paraphrase Neil deGrasse Tyson (who in the original quote was talking about UFOs) there probably is an "add demon" function on Photoshop.  My general opinion is pretty consistent with the following:


However, the bigger question is why I'm a Scoffing Armchair Skeptic about such matters more has to do with Ockham's Razor.  Ockham's Razor is rightly called a rule of thumb -- something which isn't 100% true but is still a pretty damn good guide to understanding.  The original formulation comes from William of Ockham, a 14th century monk and philosopher, who phrased it as "Non sunt multiplicanda entia sine necessitate" (Don't multiply entities without necessity), but a more modern phrasing is "All other things being equal, of competing hypotheses, choose the one that requires the least assumptions."  (It must be pointed out that Ockham himself was hardly a scientific rationalist; he's also the one who said, "Only faith gives us access to theological truths.  The ways of God are not open to reason, for God has freely chosen to create a world and establish a way of salvation within it apart from any necessary laws that human logic or rationality can uncover."  So while Ockham's Razor is a great idea, I doubt I'd have agreed with him on much else.)

In any case, the Demon of Phoenix certainly is more easily explainable as a hoax than it is that Satan for some reason descended upon southern Arizona, posed for a blurry snapshot, and then disappeared without doing anything else or being seen by anyone else.  So the second submitter is, in a sense, quite right; I would be much more likely to believe that it was real if I did see it with my own eyes.  Just looking at the photograph, here in my Comfortable Armchair, I'm still saying "Nah."

Of course, being dragged to hell would do it, too.  Nothing like a little fire and brimstone to convince one of the reality of a situation.  But until that happens, you can still put me in the "Mr. Skeptic" column.

Myths, hoaxes, and Zardulu

Unless you avoid social media entirely, you've probably seen the photograph of a raccoon hitching a ride on the back of an alligator.  It caught on because of its sheer weirdness, and was widely circulated on Facebook, Twitter, and elsewhere.


What you may not know is that it's a fake.  It's cleverly done, I'll admit, but it's an admitted hoax by a woman who calls herself "Zardulu," and who has been responsible for a number of photo and video hoaxes, one of the best known of which is "Pizza Rat:"


She's also responsible for a photoshopped image of a "three-eyed catfish" that was allegedly caught, and started a panic over toxins and/or mutagens in waterways:


"Zardulu," who refuses to give her name or show her face in public, agreed to an interview in The Washington Post a couple of days ago.  In the interview, which you can watch a clip of at the link provided, "Zardulu" appears wearing a creepy-looking bearded mask.  She is also completely unapologetic about suckering people.

These aren't hoaxes, she says, they are "myths," "pearls of merriment for the world to enjoy."  "Why wake the world from a beautiful dream," she says, "when the waking world is all so drab?"

She's even put out a manifesto, which would be an odds-on winner in the Pompous, Self-Righteous Artist's Statement contest of 2016.  Here's an excerpt:
All that once truthfully lived is now a mere effigy.  Images have displaced authentic human interaction.  Before the advent of the Internet, human life was already not about living, but about having.  Those who wished to exploit us produced images to dictate what we needed and desired.  While this continues today, social life has moved further, leaving a condition of having and moving to a state of simply appearing as the image. 
Zardulism is the art of creating and perpetuating myths.  Dramatic images and language created for the purpose of reawakening and following of genuine desires, experiencing the pleasure of life. 
In Zardulism, the imaginary streams into the actual and washes over it, floods it until it has been engrossed.  In a world where nothing is absolutely real, appearance becomes meaningless and our presumption of truth in what we were told is lost.
What I object to about all of this is not that some pretentious artist has found a way to weasel her way into the public eye with a publicity stunt.  She's hardly the first pretentious artist to do that, after all.  What bugs me is that she's blathering on about "living truthfully," when by "creating myths" what she actually means is "manufacturing hoaxes and bamboozling people."

To be fair, she's even-handed about other people's hoaxes.  You've probably heard of the Cottingley Fairies, the photograph that fooled the great Arthur Conan Doyle:


"Zardulu" thinks the Cottingley Fairies are awesome.  She says, "It was decades before anyone used the term hoax, when eventually the girls came forward and admitted what they had done.  I think that it is delightful.  Absolutely delightful to have given the world such a gift.  And it does indeed resonate with me particularly that the truth [did come out.]"

The problem, of course, is that this kind of hoax causes people to doubt everything they see, devaluing media as a whole.  I can't put it any more eloquently than Sharon Hill does, over at her outstanding site Doubtful News:
The fact is, our media system of news and information is already poisoned and rickety.  We have so much bullshit asshattery and hoaxing going on in the world today that affects peoples’ lives – their feelings towards their government, their opinions on policy and law, their choice of medical treatment, what kind of food they buy, and how they vote.  Hoaxing is not generally funny, it makes people feel foolish and angry.  They also do not necessarily learn from being conned because they often lack the foundation and skills to think critically about anything...  This artist is in no sense “brightening the world” by faking charming scenes people like or making people scared of environmental harm (the mutant catfish).  By presenting lies as not untrue, she reveals that people are dark and perverse and what may seem adorable and special is really manufactured and ugly.
To which I can only say, "Amen."  We already have enough people creating fake news to get the advertising revenue, we really don't need someone doing the same thing in the name of art.  If you want to create myths, do it the way that our great modern mythmakers and visionaries do -- people like Neil Gaiman, Alex Grey, Terry Pratchett, and Thijme Termaat -- by creating beauty, and being honest about what they're offering.  They know that the most important role of any creative endeavor is to portray the eternal truths, even in a fictional setting.

Zardulu, on the other hand, would prefer to portray banal frauds and pass them off as the truth.

Beam me up

After spending the last few days looking at such topics as the current US presidential race, the ethics of publishing teacher evaluations publicly, and the separation of church and state, let's get back to the issue that should be occupying the mind of every serious, concerned human being: lights appearing over Mayan pyramids.

It's kind of funny how lately, just mentioning the Mayans is enough to get you noticed.  This is becoming increasingly annoying to the Mayans themselves -- there are groups of Mexicans of Mayan descent, living primarily in the states of Campeche, YucatĂ¡n, and Quintana Roo, and with the exception of the few who are happy to have the money from woo-woo tourism, most of them just seem to be rolling their eyes.  In fact, one of them, Apolinario Chile Pixtun, spoke to reporters about the phenomenon, and was quoted as saying, "I came back from England last year, and man, they had me fed up with this stuff."

Well, Mr. Pixtun may be fed up, but let me tell you, the woo-woos are still starved for it.  Witness the following photograph, taken by Hector Siliezar, which was taken in 2009 but just hit the internet last week:


The photograph, which was taken while Siliezar and his family were on vacation, is of one of the pyramids at Chichen Itza.  A thunderstorm was coming, and Siliezar thought the pyramid with the dark clouds behind it would make a dramatic photograph, so he snapped several shots with his iPhone.  It was, he said, only after he looked at them afterwards that he saw what appeared to be a beam of light coming from the top of the pyramid.

It's unclear why he didn't make the photograph public until now, but be that as it may, he decided to release it a couple of weeks ago to what he calls "occult investigators."  And from there to every woo-woo in the world having multiple orgasms was only a short step.  For example, check out this article, which not only contains an interview with Siliezar and his wife,  but ends with the following hyperbolic quote from Schele and Freidel's A Forest of Kings: The Untold Story of the Ancient Maya:  "...As the Maya exploited the patterns of power in time and space, they used ritual to control the dangerous and powerful energies their [pyramids and structures] released.  There were rituals which contained the accumulated power of objects, people, and places when they were no longer in active use."

So, basically, they're implying that the beam is some kind of gigantic psychic carpet shock -- that all of the rituals and whatnot built up energy in the pyramid, and eventually it just discharged, and Siliezar was lucky enough to get it on film.

Predictably, I'm not buying it.  But that still leaves the question of what the beam actually is.  For that, let's turn not to an "occult researcher," but to a real scientist -- Jonathon Hill, research technician for the Mars Space Flight Facility at Arizona State University.  Hill, who specializes in image analysis, says that the beam is nothing more than a digital camera glitch.

What happened, explains Hill, is that Siliezar snapped the photo just as a lightning flash occurred, and the intensity of the flash "...caused the camera's CCD sensor to behave in an unusual way, either causing an entire column of pixels to offset their values or causing an internal reflection [off the] camera lens that was recorded by the sensor."  This created the appearance of a bright column on the image.  But how can he be sure of this?

Well, it turns out if you examine an enlarged copy of the image on Photoshop, you find that the beam is perfectly vertical on the image - not one pixel's variation.  I don't know about you, but that strikes me as pretty hard to explain if you think it's a photograph of a real beam of light.  It certainly struck Hill, who figured all this out, that way.  "That's a little suspicious since it's very unlikely that the gentleman who took this picture would have his handheld iPhone camera positioned exactly parallel to the 'light beam' down to the pixel level," Hill told reporters.

So, there you have it, not that it will convince the woo-woos.  In an interesting but clearly non-meaningful coincidence, I was just chatting with a student yesterday about what all the woo-woos are going to do when December 22, 2012 rolls around, and Quetzalcoatl hasn't reappeared, and our general take on it was that they'll just come up with some kind of bullshit recalculation of the date, and a few months later we'll have to go through it all again.  Because that is, after all, what it's all about -- being a woo-woo means never having to say you're sorry.
