Alas, yet another well intentioned and optimistic attempt has been made to search for alien civilizations. Don’t get me wrong, I’m all for SETI (The search for alien technological civilizations) and am glad it gets done. I just don’t think they are going to find anything, and am not surprised this latest search is a failure. Why? Some background first:
NASA has a satellite, the WISE satellite. Wide-field Infrared Survey Explorer. It basically made a survey of the sky in infrared. It was a big deal. Many new discoveries, thousands of asteroids, numerous star clusters, and a whole wealth of data about the skies. Including information on millions of galaxies. Then scientists with private funding (our precious tax dollars saved for ever more drone strikes) computer sifted through this data to find 100,000 promising galactic candidates for further investigation. They then hand searched these galaxies, looking for galaxies with signs of widespread industrial civilization. How is that? Well, the idea being that aliens that colonized a galaxy would use starlight to power industry, and thus the galaxy in question would be shy on starlight, but long on infrared, the waste product of industrial processes. The results? Nada. None of the galaxies showed anything that was obviously unnatural. A few warrant further looking, but there was certainly no smoking gun.
What can we glean from this? On the first pass, a Star Trek or Star Wars galaxy is ruled out. Bad news on one level, we won’t be joining any Galactic Federation anytime soon, because it doesn’t exist. That’s not surprising, the aliens in these sorts of imagined galaxies are pretty much just people with funny costumes. While it would be fun and comforting to find out that’s what aliens are like, there’s simply no reason to think aliens would be anything like us. In fact essentially all SETI has been doing is steadily eroding the idea of a universe populated by anthropomorphic aliens. At this point, it’s looking pretty grim for the Star Trek galaxy.
So what’s left? Well, maybe our idea of how advanced alien civilizations would look needs some tweaking. Most, if not all, of our ideas about SETI involve searching for aliens who are acting like us. Granted, how to imagine aliens who aren’t like us is a bit tricky. I suspect the goal shouldn’t be to decide what to look for and look for it, but try to look for anything that doesn’t have a good natural explanation. Granted that’s a pretty nebulous concept in and of itself, but it has the advantage of eliminating our own prejudices about what aliens will be doing. And yes, it’s also limited by the fact that our understanding of what is and isn’t natural in the Universe is also pretty nebulous at this stage. Still, it would be a start, and I hope at least some in the SETI community are looking into searching for the unexpected.
Lastly, and the point that seems to distress so many people, it’s possible that we are alone. We simply don’t know how likely it is for species like ours to come along and start building technological stuff. Maybe it’s so incredibly unlikely that it’s only happened once. People love to claim that the size of the Universe means there “has” to be others, but that’s simply an argument from big numbers. What are the chances that one grain of sand on Earth contains an exact miniature replica of a McDonalds® outlet down to the smallest detail? Saying, there’s trillions of grains of sand so one must contain a miniature McDonalds® because there are so many grains of sand, is an absurd argument.
In any event I hope SETI continues. Heck, I wish it was better funded, but it’s too easy an idea to ridicule and there’s no SETI lobby to speak of, and certainly no SETI industry, so it’s going to continue to be a privately funded search. I wish SETI all the luck in the world, I just don’t recommend making any bets on it succeeding any time soon.
Have a great weekend everyone.
(The above image was taken on Mars about a year ago by the Curiosity rover. As a NASA photograph, it is for most practical purposes, including inclusion in this blog, a public domain image. NASA does not in any way endorse Doug’s Darkworld. I used this image because, gee, Mars is sure looking like a barren lifeless rock. And because I still think its effing incredible that we have machines on Mars able to send pics like this. The blue sky means it’s sunset. On Mars the sky is normally scarlet or a bright orangeish-red colour. It turns rose at sunset and sunrise.)
Well, there it is. Patomsky Crater. A 40m high crater in remote Siberia. Discovered in 1949 by a geologist named Vadim Kolpakov. Well, discovered by the outside world, the locals had known of it. It was made sometime in the past few centuries. How was it made? That’s the mystery. Geologists have been studying it for decades, and they still don’t know. Yes, scientists don’t know how this pile of rock was made. I’d say it was like a crop circle made of stones, but scientists know how crop circles are made.
What could it be? At first it was thought maybe it was something that Stalin had made by gulag labour. It’s certainly possible, he had some odd things done. However, geologists visiting the site ruled that out, it is clearly a natural formation. One possibility was that maybe it was some sort of explosion caused by uranium ore going critical. Something similar happened in Gabon, Africa, some 1.3 billion years ago. Alas, no Uranium or radioactivity has been found, so that idea was ruled out. Impact? Well, some scientists still think so. In fact for awhile it was thought it might be related to the Tunguska impact of 1908. Alas, no meteoric material has been found. And its date has been pinned down to about 250 years ago, long before the Tunguska event.
So, volcano? Well, there’s no volcanic rock in the region. The crater itself is made of limestone, hardly a volcanic materiel. There’s no volcanoes or extinct volcanoes in the region. And it doesn’t resemble any known volcanic crater. Still, most geologists think it must be some sort of eruptive process. Some geologic process heated ground water causing one or more phreatic eruptions. Research continues.
The significance of this discovery? It’s interesting on several levels. The first thing is that it is an example of the limits of science. Lay people, especially fundamentalist religious types, often seem to be under the impression that scientists know everything. No, they don’t. In fact it’s safe to say that what scientists don’t know is vastly, maybe infinitely, greater than what they do know. Every new scientific discovery expands the boundaries of what we know … and expands the boundaries of what we don’t know. It’s certain religions that claim to understand everything, most scientists long ago got over that conceit.
Anything else? Well, the woo woo crowd has weighed in. Some have claimed that Patomskiy Crater is a crashed UFO. Some reports claim that a cylindrical object has been identified buried in the crater. I’m pretty sure if Russian geologists had actually identified some mysterious object was buried in the crater, it would have been excavated promptly. Still, it’s not a big topic in the woo woo crowd. Which in and of itself says something. they aren’t really interested in mysteries, only mysteries that can be easily folded into their pseudoscience view of the world.
Yes, I’ve become more intolerant of science deniers. The religious ones are worse, because they are destroying the political process in the USA. That’s a story for another post. The woo woo ones, well, they aren’t helping. Because science doesn’t yet doesn’t have an answer for something, UFOs aren’t the default. Or angels. It’s the beauty and wonder of the world, science has discovered that there is no need for supernatural explanations, and right now UFOs are as supernatural as angels and demons.
So, what created Patomskiy Crater? I’ll certainly go with the scientific consensus. Some sort of as yet unexplained geologic process. Still, the exotic impact theory hasn’t yet been ruled out. Exotic as being an impact of something other than the typical stone or ion meteorite. Something much denser than either. The universe is stranger than we can imagine, Patomskiy Crater is proof of that.
And the most wonderful thing about science, when it does explain Patomskiy Crater, it will make our understanding of the world a little bit bigger. We will not understand everything, but the more we understand, the safer we are. Our campfire in the dark gets a little brighter.

Well, an acquaintance showed me some exciting video the other day. It was of Kanzi, a Bonobo that has learned to communicate with humans by pointing at symbols. Kanzi knows thousands of symbols, and videos of him are all over youtube. It’s pretty impressive stuff. Kanzi can give and understand a vast array of commands, and interacts with his handlers regularly using the symbols. To primatologist Sue Savage-Rumbaugh, who has been studying Kanzi all Kanzi’s life, Kanzi exhibits “advanced linguistic aptitude.” Kanzi has even been interviewed on TV, heck, how many people can say that? Is the Kanzi the breakthrough primatologists have been striving for for decades, have humans and an animal learned to communicate? Well, yes. The more important question though is this, is Kanzi the the holy grail of animal communication research, has Kanzi learned to speak?
Alas, while there is a lot to be learned from Kanzi research, don’t place any pre-orders for handy Bonobo house servants. Let’s start from the beginning. In 1969 a chimpanzee named Washoe rocked the scientific world, the first chimp to learn sign language. Washoe was a media sensation, and launched a whole raft of primate sign language research. People everywhere loved the idea that chimps could talk. Sure, their vocal cords can’t pronounce human words, but with sign language, that barrier was broken! Unfortunately, upon closer examination, Washoe well, washed out. Her handlers had been wildly optimistic about their interpretations of many of her hand movements. Even one of her most famous examples of “speech,” her making the signs for water and bird upon seeing a swan, isn’t particularly amazing. A swan is a bird, and it was on water, all it really showed was that Washoe knew the signs for water and bird. Science moved on, and while a few researchers went forward, other than in the popular perception, signing chimps were a dead end.
Then, along came Sue Savage-Rumbaugh and Kanzi. No messing around with ambiguous hand movements, by learning actual symbols, his communications were clear. Kanzi learned thousands of symbols, and could use them to signal his wants and even to some extent communicate his internal states. Watching the videos of him is pretty amazing, at least on a superficial level. Kanzi can hear complex commands and act on them, surely that means he is using language similar to how humans do. Had Sue Savage-Rumbaugh done it, was Kanzi the first animal to speak with a human?
Alas, no. There’s a number of problems with the “Kanzi is speaking” scenario. The first is how he acquired language. When human babies start learning words, they almost immediately begin constructing sentences out of them. And as they learn more words, their sentences get longer and more complex. When Kanzi (or other “talking” chimps) start to learn words, they pretty much don’t make sentences out of them. And as they learn ever more words, their sentence construction remains at their initial very modest levels. Kanzi’s average sentence length is … 1.15 words. In other words, Kanzi for the most part uses exactly one symbol to express himself. And while Kanzi’s understanding of symbols might seem impressive, it’s more substance than real. Yes, Kanzi seemingly can understand commands involving several words, but that is not necessarily language. IE if one tells Kanzi to “put the doll in the bucket in the other room” all Kanzi really has to know is that he is expected to manipulate the doll, the bucket, and the room. That’s not language.
More accurately, Kanzi does not appear to understand grammar at all. Grammar is how words strung together modify each other, the essence of language. IE take these two sentences, “Man bites dog.” and “Dog bites man.” A human child can understand the clear distinction between these two sentences almost as soon as they start learning to speak. Kanzi can’t, when carefully tested with simple sentence pairs like this, his “understanding” doesn’t rise above chance levels. Despite learning language for decades, Kanzi is 26, he doesn’t understand grammar at all. As one primatologist puts it, no ape has ever asked a question or expressed an opinion.
Will humans ever communicate with animals? Not looking good, human’s facility with language most definitely is something that no animal, no matter how clever, has ever demonstrated. Is there a lesson here? Of course, I’m always illustrating some point or other. The main point being how people’s public perception of science is often at odds with reality. Most people one talks to about signing and symbol using chimps are absolutely convinced that indeed, these animals are “speaking.” I suspect this is a combination of wishful thinking; both on the part of the public, the media, and on the part of the very sincere researchers involved. Sadly, just because a handful of researchers and the public thinks that something is a scientific reality, doesn’t actually make it so.
Lastly, Kanzi is a curious example of borderline research. Nothing is ever black and white, the boundaries between science and nonsense aren’t as clear cut as many would believe. Talking apes aren’t pseudoscience, actual scientists are working in the field. And they sincerely believe they are onto something. I suspect the amount of research devoted to this will decline over time, that’s usually the case with unproductive lines of research. Still, all this talking chimp research has at least cleared up one thing: Chimps can’t be taught to talk.

I got it from this fine site, which presumably holds the credit and copyright. And yes, I have been ill. I have returned and am blogging again. That’s good or bad depending on one’s perspective I suppose.)
No, this picture wasn’t it. I suspected it might be an explanation for what I saw, but I don’t think so now. I digress. I’ve had a handful of experiences in my life for which I have found no really satisfying explanation. A lot of people have had similar, I’ve certainly heard a few stories in my time. And since I find mysteries fascinating, I will share the few I’ve experienced. Partly just for fun, partly to show that mysterious things do happen, and partly in hopes that someone says “I know what you saw!” So far no one has even come close with this one, I’m still baffled and it happened over twenty years ago.
So, 1990 or so, Washington State. A friend and I were camping for the weekend and drove around much of Saturday looking for an open campground. We eventually found a place where we could park the car, and hike down into a canyon with a nice secluded camping area by a stream. While people obviously went there occasionally, there was sort of a path down the hill, there was no one there that weekend. There were a lot of old cans and bottles from the 1930s scattered about, someone had spent a summer or two camped there back then. It really was a sweet spot, but you couldn’t drive to it and it was hard to find. We got lucky.
There was a well trodden game trail along the creek, just fine for humans. A few feet wide, packed earth surface. We were car camping, not backpacking, so we had to make several trips up and down the canyon side to get our stuff to the campsite. It was afternoon in the shade, but full summer, and even in the canyon it was still full daylight. Ahead of me on the path as I’m walking I see something. It was maybe an inch tall or so, and it was solid white. I couldn’t make out its shape, this all happened very quickly. I saw it on the trail, then it opened a little trapdoor, popped into the hole, and pulled the trapdoor shut. I was surprised, but stared at the spot where it had disappeared as I walked up, and poked around with a stick. I didn’t find anything but solid packed earth. I was puzzled, but didn’t know what else to do. I seem to recall thinking that it must have been a big bug of some sort, but it was pure white, I’d never seen a white bug.
And that’s the story. I recently did some research on trapdoor spiders, and the image above made me wonder if I’d seen one of them, and somehow the white of the trapdoor was the white I had seen, the incident did happen very fast. Alas, from what I can tell, trapdoor spiders aren’t found anywhere above central California. That pretty much rules them out. I’ve never heard of a big white bug that has a trapdoor in the ground, but who knows. Ring a bell with any reader? Is there any sort of bug or animal that fits this bill? I’d love to hear about it.
There is always the possibility that this never happened, or at least not the way I am remembering. Science has shown that memory is a very sketchy thing, and easily modified or induced. Maybe I dreamed this for example, I often have vivid dreams when camping. It seems odd to me now that I didn’t investigate further at the time, it was right outside the camp. On the other hand, I can see myself deciding to leave it be, since I wouldn’t want to hurt it by scraping around looking for it … whatever it was. We all have false memories, and we all misremember things. Memory is a story we tell ourselves.
Lastly, I suspect it’s experiences like this that have seeded, so to speak, a lot of folklore through the ages. It wouldn’t be too hard to convince myself I had seen a humanoid figure, heck, I’d be lying if I said I was sure it wasn’t. In earlier times when the world was more mysterious, the idea that there were other humanoids living around us wouldn’t be all that odd, why not? And the brain, our wonderful human brain, is a pattern recognizer. The best ever in fact, there’s thinking that this is one of the things that makes us uniquely human. And in many cases, it works too well, and sees patterns that aren’t even there. Jesus on a piece of toast nowadays, back then fairies and elves in the woods. And Gods?

Spontaneous human combustion and Bigfoot, two favourite weird topics from my youth. And in fact big favourites of all sorts of people who like to read about weird things, numerous books have been written about both. And it’s safe to say that many people are firmly convinced of the reality of both. And that’s where I recently discovered common ground between the two, in both cases, like Oakland, there is no there there. I know, this is turning into a distressingly skeptical blog. If the gentle reader wants to continue believing in the reality of Bigfoot or SHC, it’s probably safest to stop reading now. The older I get the more I realize that almost everything in print online and off has little or no actual bearing on reality. I don’t think most people could find reality even if they had a map. Or worse, they think things like the Bible and the Koran are the map. I digress.
Moving right along, spontaneous human combustion (SHC.) This is when a human body is found where the body has almost been completely destroyed by fire, with no evidence of how the fire occurred, and often little to no fire damage to surrounding items. And no doubt it would be mysterious to find someone burned to a crisp in their living room with little fire damage to other items in the room. The phenomena is definitely real in that the finding of such bodies is well documented and continues to occur occasionally. And is even sometimes officially classified as spontaneous human combustion. Though it is done so because the cause of the combustion was undetermined, not that there was anything weird or supernatural about the deaths.
That’s the first thing to understand about SHC is that while it sounds superficially implausible that a human body could burn to a crisp without setting a room on fire, in fact this isn’t particularly mysterious. Humans, and this is especially the case in SHC victims, have a lot of body fat. Think candle. Tests with pig cadavers that once a body begins to burn, it will indeed burn up over a period of time without undue damage to other items ion the room. The flames aren’t particularly hot, and they are confined to the fallen person’s body and clothing. And it’s not particularly hard to ignite a body, any open flame will do, especially if clothing catches fire. Pretty gruesome, but not mysterious.
It gets worse. How is it that someone can catch fire and then just do nothing and let it burn? Well, undoubtedly some SHC cases are people who died of natural causes while they were smoking. The classic case though is found on a kitchen or bathroom floor, as if the victim was felled instantly somehow and began to burn. In fact that’s exactly what happened, though the other way around, they caught on fire and were felled instantly. What made them drop dead? Their clothing on fire. How does that kill someone instantly? Easily as it turns out, which I didn’t know. What does one do if one looks down and their shirt is on fire? In many cases people panic. They run for a bathroom and kitchen, and in some cases they look down and inhale at the same time. And if someone gets flames into their lungs … they drop dead. Well, they pass out I guess, but the effect is the same. Yes, another mystery of life that has a prosaic explanation. Back to the drawing board.
Or, in this case, Bigfoot. Someone mentioned something about that I wish I had thought of. Bigfoot tracks, still found all the time. A friend asked, why don’t they just have dogs follow the trail? Hmm. Not just a good point, a damning point. People hunt with dogs in Bigfoot country all the time. In fact all sorts of people with dogs, hunting or not, travel in Bigfoot country. A Bigfoot can outrun a dog or a pack of dogs? Not if it’s a flesh and blood animal. Granted the Bigfoot coffin was already firmly nailed shut, but this objection is really hard to explain away. Impossible really considering how long humans and dogs have been wandering around the USA.
Fortunately the world is still full of imponderable mysteries. Like how come Americans never learn from their foreign policy mistakes? Have a great weekend everyone!

Diffuse Interstellar Bands. (DIBS) What are they? No one knows. Where are they? In deep space. Were they the inspiration for Pink Floyd? I seriously doubt it. What am I talking about? Diffuse Interstellar Bands. Sheesh, pay attention.
OK, let’s start at the beginning, the early 20th century to be exact. Scientists by then were studying the light of stars. A spectrum is the light emitted by a star or bright object passed through a prism. Molecules in and near a star will block some of the spectrum, making dark stripes as seen above, these are called absorption or spectral lines. Thus scientists can tell what a star is made of. It even works with reflected light, this is how they tell what planets and asteroids are made of. This is all of course terribly simplified, because I have a very dim grasp of it all myself. All well and good until 1922, scientists happily studied what stars were made of. However, in 1922 astronomer Mary Lea Heger discovered some absorption lines that were much more diffuse than the typical lines in a star’s spectrum. She also found that the lines were associated with the galactic interstellar medium, not stars.
This was a head scratcher. People commonly think that space is a perfect vacuum. It isn’t, it varies widely, but one atom per cubic centimetre is the “average” density of interstellar space. It was thought this matter was so diffuse that while it might dim an entire spectrum slightly, it wouldn’t make lines. Well, sciencists were wrong, some molecules in interstellar space were apparently common enough to cause absorption lines. Mary discovered a few such lines, and by 1975 about 25 had been discovered. By 1994 when the first conference on DIBs was held, about 50 were known. Today about 300 have been discovered, illustrated above. The reason it’s a head scratcher is because no one knows exactly what molecules are creating these lines. Despite scientist’s best efforts, they have not been able to replicate the lines experimentally, or even come up with a theoretical calculation that explains the lines.
This is a major scientific mystery and has been for decades. For reasons I don’t understand, let alone can explain, it does seem pretty certain that the lines are caused by molecules, not single atoms. And it also is clear that numerous different molecules are involved, a single type of molecule couldn’t produce over 300 DIBs. The best guess is that they are being caused by long chain molecules. Polycyclic aromatic hydrocarbons, long carbon-chain molecules, and fullerenes are all strong suspects. And that’s that. Somehow our galaxy contains dust or gas of unknown origin or composition, what it is and how it is created is still a complete mystery.
Is this important? In a practical sense, no, figuring this out isn’t going to change our lives. Not figuring it out will have the same effect. It’s important though to understand that there are plenty of complete mysteries in our scientific understanding of the Universe. A lot of people, especially certain religious types, don’t seem to understand that. Science can’t currently explain everything, and there doesn’t appear to be any chance that it will ever explain everything. This isn’t a failure of science, th0ough it is oft presented as such by science-deniers, it is one of science’s greatest strengths. So whenever I stumble across an unsolved scientific mystery, I am impressed by the mystery itself, and I’m impressed by the fact that science even uncovered the mystery. Is there any chance that the solution to DIBs will force a re-examination of other aspects of science? Possibly, but I don’t know how possible. When it comes right down to it, our understanding of the cosmos is still in its infancy.
One last little observation is that I am always curious that science deniers miss things like this. If one was going to construct logical sounding attacks on science, mysteries like this would be a great place to start. Instead, the science deniers seem to make very little effort to find new arguments, and simply recycle old arguments. Some of the “objections” raised about evolution date from the nineteenth century for God’s sake. And while some of them were valid concerns then, a hundred years later they have long been laid to rest. I suppose it’s further evidence that science deniers are in actual denial about science, since few of them seem to take the time to even understand it well enough to construct modern arguments against it. Or it could mean that when people study science hard enough they realize its true, they are converted to science and reason?
Pause for laughter. Beats me. The older I get the more I find people and their motivations both painfully predictable … and painfully puzzling. It’s a conundrum it is.

Interesting, nu? I got a lot of guesses on Facebook. A new planet, water going down a drain, a newly discovered galaxy, and my favourite: a cake mix gone horribly wrong. No, it’s not a cake mix gone horribly wrong. Many people did guess it was some sort of astronomy photo, and they were on track. The white things are indeed clouds, this is the surface of a planet photographed from space. Not Earth though, in fact six Earths could fit inside the hexagon. This is one of the gas giant planets, Saturn. It’s the clouds surrounding the North pole of Saturn. Note the hexagon shaped cloud, what’s up with that?
No one knows. It was first observed when Voyager went by Saturn in 1980 and 1981. No one had a clue then. In 2004, more than 20 years later, the hexagon was still there when the Cassini Probe arrived at Saturn. So it’s a persistent feature. And nothing else like it has been observed anywhere else in the Solar System. Scientists think the hexagon cloud formation is created by a jet stream whipping along at over 200 mph. The hexagon formation rotates with the planet, and its latitude doesn’t change either. Yes, a permanent, or at least remarkably stable, hexagon shaped torrent of wind whipping around Saturn’s pole. Cassini recently has been getting much better pictures of the hexagon lately as Saturn’s northern hemisphere has moved into sunlight, so scientists hope to begin to unravel the mystery soon.
Why so interesting? (Honestly, any reader thinking that has likely long ago abandoned my blog of scientific and historical weirdness in search of blogs about “The Shove.”) The hexagon is interesting from a number of perspectives. Scientists are interested in it because they can’t yet explain it. That’s kind of the whole point of science. Looking at stuff and figuring out why it is so. This hexagon is one of the big mysteries of the Solar System. It’s an example of no matter how much we know, we are always finding things no one expected or predicted. That’s one of the beauties of the scientific method, knowledge is never complete, and it always has to be modified or expanded in light of new discoveries. Kinda the opposite of most philosophies and religions, that for the most part start with a conclusion and then shoehorn new discoveries into it. That’s getting pretty ridiculous now considering some of these religions started in the Bronze Age. Science put man on the Moon, religion put man on a cross.
Philosophical concerns aside, study of Saturn’s hexagon could prove valuable insights about Earth. This is because the hexagon is a weather and climatic phenomena, and studying how weather and climate works on other planets can prove an interesting comparison to how it works on Earth. And of all the things scientists study, weather and climate are certainly near the top when it comes to practical application. When it comes right down to it, scientific investigation of any topic can yield valuable and practical insights about the world around us. That’s one of the silliest and destructive myths about scientists, that many of them study obscure stuff of no use to anyone. Scientists are studying reality, and everyone is connected to reality. How much more practical can it get?
Personally I just think space exploration is the shiznit. I loved exploring as a kid, and never outgrew it. Go somewhere one hasn’t been, see something one hasn’t seen before. And space exploration is the ultimate place to go and see stuff no one has seen before. “To boldly go where no man has gone before.” Granted that’s questionable grammar and not exactly a feminist way of phrasing it, but fun none the less. And who knew Leonard Nimoy could play the guitar anyhow? OK, it’s been a long hard week and this is devolving into gibberish. Enough.
Have a great weekend everyone!
