Selects: How Cave Dwellers Work

stuff you should know. Wow, it's the same energetic edition a little bit. Yeah, yeah, it's cold. I'm energized by the cold, energized and like just a little Yeah, so you're not energized, that is what we're saying. I'm a little innersized. I feel like I'm I'm fine. Right. Why do you say that because he's sound like you're sleepwalking. Oh really? Yeah? Oh I thought I was just speaking fast. Oh no, no, I thought that's why you're being sarcastic.

I'm sorry to everybody who's sitting through this right now. So I'm down in the dumps. You are right, Yeah, no, I'm fine, okay, I'm just it's the cold. It's a little dreary outside of Today's the day it finally started to get to me. So you're ready for spring? Yes, Um, Emily is ready for spring. I'm like, it's you know, it's January. She said, no, no, but it's Georgia, so we could have spring in a few weeks. It's true.

We kind of had it yesterday. Um. You mean. And I have been making these little bird feeders, like with cookie cutters and shapes and all that stuff. I've been trying to get the physics of it down to hang them so that the birds can like land on them there, so I incorporate twigs and these things. They can spend a little time there. Yeah. And there's this, um, a little s ob of a squirrel that has my porch all figured out, and it keeps like getting these whole

bird feeder cakes. And I realized, like I'm spending a lot of time like trying to thwart this squirrel figure out the physics of bird feed and I'm like, yeah, I'm ready for spreaking. Yeah, we have one of those cake holders for birds, but it's really a squirrel feeder. Yeah, and they eat it in like a day. Yeah. This this squirrel can eat several cakes and it makes a mess. Yeah, all right, Cave Dwelling. I can't remember I've I've asked you before, but I don't know if you've seen it,

um since I asked you, because you hadn't. A Cave of Forgotten Dreams by Werner Herzel. No I watched, well, I watched like twenty minutes of it this morning just to get the gist. You got the gist in twenty minutes. Well, I can't wait to watch the whole thing though. It's pretty much that. Yeah, but I don't want to watch it. Well, yeah you should. It's neat. The whole thing's neat from beginning to end. But I mean like it's a I think maybe a two hour long documentary. Yeah, on a cave. Yeah.

In the cave art, it's phenomenal. Yeah, I know the one in uh well they're both in France, right, Yeah. The one that gets the most press is the last Last Go, which is great, but this one, to me, the art is better. Well, Alasco gets lord pressed because it was discovered in nineteen forty, this one that weren't Herzog did a documentary only discovered in year old art. It's amazing, Yeah, it is, and it's all spectacularly preserved.

One of the benefits of discovering lastco in nineteen forty was that when Chauves Cave, the one that was discovered in ninety four it's even older, was discovered, we'd already figured out a lot of stuff along the way and how to preserve it right, right, so we could go in there and sort of TCB. Yeah, you need to cut down on the carbon dioxide that people are breathing out herzog in there. Yeah. Um, you need to cut down on flashes flash photography, because apparently flashes really do degrade.

There's something called photo degradation of especially old pigments um, and it's basically like releasing the sub light over the course of a few milliseconds. Makes sense, that's one flash, but if you add up all the tourists over the years, all of a sudden, you're basically bringing the sunlight artificially into this cave and it's degrading the pigment. So there's also sorts of stuff we learned from Lascow Cave that's not being applied to Chouve Cave. Um, but yes, it

is older, it is more awesome. And the very evidence of old cave paintings and all the artifacts and bones that are found in caves would suggest that there, in some distant past of prehistory was a race of hominids that were cave dwelling hominids. They were a race of cave dwellers. Yeah, that must be correct, right, ringo star. Yeah, I saw the movie Caveman or was that a documentary? What's in a movie? Yeah, you're thinking of Quest for Fire. Yeah,

well those are all great movies. Plan at the Cave Bear, But well I was setting you up and you you didn't Well no, okay, thank is the answer. Um. They now believe that, uh, people through different periods of ancient history have dwelled in caves at times that probably didn't like set up permanent residents in caves. Yeah. And the big pivotal evidence of this is that the people who would have supposedly lived in caves at that time were

all nomadic hunter gatherers. They wouldn't have been stationary for in any kind of dwelling. Yeah, they gotta go out and find the meat, right, So there was no such thing as a species of hominid that you could say our caveman. Those were the caveman. All the other ones just lived. However, most of the people who are alive in what we're talking about the Paleolithic era, which went back from about two million years ago all the way

up to about ten thousand years ago. That's the Paleolithic era um where they lived in all sorts of different kinds of shelters, caves being one of them. Yeah. Uh. One reason to go into a cave is obviously it's gonna and we've covered this is I think our third Yeah, the cave Sweet Cave Sweet, Yeah, biospeleology, which is awesome sloking. Yeah,

and then this one cave cave. Followers who thought that we would do the three part series on caves, ever, well, and this covers cave arts such that this will probably be it. Don't you think? Is there anything else? I can't cave anything? No, not really, Nick Cave. Maybe we can podcast on him. Um. So some reasons to go into a cave to begin with, obviously is to protect yourself from the weather. I think it's probably the leading it's raining, let's go inside that room. It's not raining

in the cave. Um to protect yourself from animals, because if you go back and listen to our biospeleology, only certain animals are in caves, very few and not a lot of like you know, big nasty man eaters, although back then they would have run in the cave bears clan at the cave Bear. I don't know if sabretooth tigers were cave dwellers, but I've seen a lot of Flintstone episodes and from what I understand they do, they

did go into caves. Of course, you run into the proteus salamander, which you would not want to run into. Remember the three ft long eyelis salamander. Remember white nightmares like once a week. Yeah, I don't think you'd do anything to you, but man alive. Yeah, I wouldn't want to see that thing, Like you wake up looking face to face with that eyelis monster. Yeah. Yeah, but um, protection from animals, protection from weather, but protection from other

people wasn't really a big reason. Because this is good to know. I think I kind of got along and help each other in general. Yeah, there's something called paleolithic warlessness. Yeah, like the concept of war, organized war is apparently only maybe twelve to sixteen thousand, eighteen thousand, maybe years old. I think probably once people started getting comfy as when they started wanting to fight each other. Back then, they

were just trying to survive. Yeah, you know, well there's a whole idea that agriculture and sedentary existence is what led to warfare. What what that guy's got exactly? Yeah, yeah, it's basically and lead to surpluses. So people fared over surplus. You're starving over here, and they've got all this grain over here, so you go kill all those people and take the grain. We should do a history of war. That'd be good. Well, that would be good. But there

were obviously there were scraps in the Paleolithic. I mean, it wasn't all like one in Roses. You tried getting along with Ron Livingston now it's not his name. Oh everybody gets along with Ron Livingston. He's from office space, right, yeah, you know the other guy. Yeah, Um, that's a pretty good mess up. There were scraps every now and then, like obviously over you know, territory or food or fire. But it wasn't like, hey, let's go to war with

this tribe. We don't like them, or we want what they've got, because I mean the consensus among anthropologists apparently is that war is relatively recent. It's not that ancient. It's certainly not as ancient as a lot of the cave art we run into. Yeah years, so, um, you've got shelter from the elements, protection from animals, um, nice steady temperature as we that's a big one. Yeah, because the cave typically is about in the fifties fifties degrees

fahrenheight um round. Yeah. So if you are in a cave and you're living there and it's summertime, you are sitting pretty If it's winter time, depending on where you are, so you're in northern Europe, you're still sitting pretty. Sure. All you have to do is build a little bit of a fire and I hope you don't smoke yourself out, and you are, you're you're in some climate controlled luxury,

especially for the Stone Age. You know, Uh. One reason that everyone didn't live in caves, and this is something I learned when I went on my caving experience, which is detailed in the Spelunking episode, is that even though there's tons of caves, not a ton of caves are like great to live in. Like a lot of them you might walk right past because it's just a hole in the ground. You have no idea there's an underground cavern.

A lot of them are inaccessible. Um, a lot of them have our active so that means they have water, which isn't super hospitable inactive cave. Yeah, it'll flood. Yeah, you don't want to be in there when it floods. Yeah, they're just not like generally, they're not like these huge cavernous like, oh, it's a big underground home. Well. Plus also there's a lot of gravel slopes which if you stand on them you can fall and die. You learn

that pretty quick. Yeah, there's a cave dweller, lots of different exits and entrances and shafts and things like that. They can be misleading and confuse you and dark get you lost to your death. Yeah, apparently just a couple of dozen feet. I don't remember. There's the light zone, the twilight zone in the dark zone, and I don't remember where the twilight zone ends in the dark zone begins.

But once that dark zone begins, there's no light, like no light and like you said, you can't just start a bunch of fires because you can die from smoking yourself out. Yeah, you can hit your head on stealag tights. That's true. So it's not the most common thing to find like a great cave for ten or twealth people to live in, But when they found them and they needed them, they would dwell in them, right and um. Again, that's one reason, for several reasons why people didn't just

live in caves all the time. But another reason is because they knew of other ways to live. They could um stretch animal hides over of structures, they built um earth and dwellings where they would build like a lean to or something and then pack earth over it, which is another way to control the climate or temperature in that little dwelling. And again, they were nomadic. They were following herds of bison and mammoths and um. You know,

it's a big, beautiful world too. Let's not forget Yeah, like, why would you want to go live in a cave your entire life when you've got the run of the place of planet Earth and all it has to offer. You know, if there was a hominid uh that could be considered cave dwellers though it would probably be the Neanderthals. As we understand right now, it wasn't too terribly long ago that we discover are the new species of UM human ancestor well, at least they were contemporary with modern humans.

The dennis Ovans. Oh who is that? Um? They they were their type of hominid that lived in the thirty fifty thousand years ago at the latest, I think maybe. And um there's a cave in Croatia I believe where they discovered a moler and they thought, well, no, they discovered a finger bone and they thought it was Neanderthal ar human and they ran the DNA tests and they're like, uh, this is neither what is this? So they named it it's a Dennisova cave or dennis Cave, one of the two.

And they named this new species of hominid a the dennis Ovans. And then they looked at the human genome and they're like, oh, well, you apparently in our bred with them, because we have a little bit of dennis Ovan and all of us most of us. Yeah, people who UM stayed in Africa and didn't disperse like Neanderthals or other modern humans too, apparently didn't have the opportunity

to mix with Dennis Ovans or Neanderthals. So typically people of European descent Native American descent, they will have Um Neanderthal and Denisovan in them. But there's this cave in Croatia has evidence that these Neanderthals, humans and Dennis Ovan's possibly shared these caves at the same time. Isn't that crazy? They Yeah, they didn't necessarily sit around a campfire with one another, but they they may have been using the cave within you know, the same year or something like that,

depending on the season. I pictured them making s'mores and say, how do you get your back so straight? But I mean, think about it. If they were breeding, you know, then maybe it wasn't those caves. Jerry either laughed at that or she's choking on something food or both. Perhaps. Uh So, Yeah, the Neanderthal was um all over Europe and during a glacial period, so obviously they've got harsh climates, so they might want to poke into a cave every now and then and warm up. Um. And there are a couple

of strategies that archaeologists believe we're used back then. The circulating mobility and radiating mobility and circulating was um. And I kind of like this idea is had several temporary camps kind of scattered all over a region, and it's kind of like just having different homes and you would just go from place to place and live in your little home and hunt and gather. Uh. Or it's the

same thing the ultra wealthy dude today exactly. Or radiating mobility was when you had one main camp and you would just go out as far as you could to hunt and gather from that camp. Right, so you had other shelters along the way. I don't know. I thought the radiating mobility was just the one camp and you came and went to that camp every day and that was the difference. Is that right, It's possible. I think

that's right. Um. And apparently some of these camps were in fact caves at times, right, So they were using caves for sure. They were um doing something else too. Uh. They were creating art in these caves, boy were they? Which has people UM baffled. Alright, cave art and if you have in your mind a cave art is like super primitive, like you know, is that a buffalo or is that a giraffe? You should go just google the cave art in those two caves especially. Oh yeah, Calvette

calve chave. Yeah. One of the things that Herzog talks about that they figured out, if I remember correctly, is that the torchlight, the flickering torchlight, produces movement of these animals. And um, they think they're they're wondering whether that was like intentional or not, and they think it probably was intentional before they make a little pounced interestingly. But it's like legit art and legit talented painters. Yeah, when you

look at the stuff, it's pretty amazing. They hadn't discovered um perspective yet, so it's all flat, two dimensional. But um, first of all, they're creating these things in utter dark by torchlight. Yeah, using earthen pigments like ochre for yellows and oranges, Um, charcoal, charcoal for black was the red one.

I think for red they used iron oxide and they used charcoal and manganese for they're using very very primitive brushes in the dictionary sense of the word, yeah, or there early airbrush artists essentially, because they're blowing this pigment through a h a tube, a tube or just out of their mouth right onto the walls. Yeah. Uh, and then they're also using their hands and their fingers. But you're right, man, there are some especially when you take

all of this into consideration. Yeah, it makes some of the art that was made just staggering. Yeah. Apparently they would use to some of the uh texture of the cave itself, like if there was a an indentation or not an indentation, but what's hopps has been indentation. Yeah, there was a bump that looked like a rhino horn. They would incorporate that as the rhino horn, and all of a sudden you had I mean, it's not quite

three D, but it's definitely more than flat. Yeah. Right, you know they're like, it's not perspective, but it's gonna have to do. Uh. They now have evidence in some of these thirty thousand year old caves of scaffolding. I hadn't seen that. Yeah, it's pretty cool, and um principles of stenciling, early principles of stenciling. And apparently when uh Picasso visited lescal he said to his guide, they've invented everything, and he was just like blown away. Yeah, basically like

I'm just copying these early hominids. It's pretty amazing. It's about right too. Yeah, and actually I don't know Picasso's all right, but some of these caves they haven't beat They didn't look funny, they didn't have one eye, and

they didn't wear braiths. Um So, most of the subjects of cave paintings that have been discovered so far, and there could be tons and tons of undiscovered caves, like the one at Chauves wasn't discovered until because at some point in the past a rock fall happened and closed the cave off to view and was just happened to be discovered by some hikers. Man, can you imagine being the person that discovered that. It would have been pretty cool. Um So, most of the cave art that has been

discovered so far, it depicts herd animals. Yeah, animals, by and large, there herd animals. They're bison, their buffalo, their um, mammoths, things like that. Um. There's very few images of vegetation, very few images of humans. The images of humans there are tend to be things like fertility idols, like female fertility idols, And there's a theory out there that those were painted by adolescent boys. Yeah, as like basically early

you know, club magazine or something. And uh, that may or may not be correct, especially when they found that in France and Spain a lot and possibly the majority of cave art was done by females. They recently discovered you know, the hand ones handprints, they figured out recently that most of those are female hands because of the they they give away of the sixth finger, that only females. That. Um, there's an article that I can recommend that actually is

what inspired Berner Hertzog to make his documentary called First Impressions. Uh. It was in the New Yorker in two thousand eight by Judith Thurman and it's super awesome. And uh, she basically says there's a couple of camps when it comes to cave art experts. Ah, those who can't resist advancing a theory about the art, and then those who say there never will be enough evidence to support one, so you're all just sort of making up these theories. Yeah,

I think that's healthy. That second camp is much healthier because it is all theories. But I like the theories though, Yeah, And I don't think we should just be like we'll never understand that, so let's not even try. Yeah, I think we should just remember that when we are trying to understand them, they're all just guesses, and not even really educated guesses at that. Yeah. I think my theory of why there are animals mostly is because it was

super important to their survival. And maybe it was you know, uh, some communication to leave for another person later or to each other. Maybe. Yeah, it could be, Um, there's lots of buffalo in this area, so get to hunting, or don't hunt these guys, because I just killed a bunch of them by forcing them off a cliff. It was awesome, by the way, to see, but there's not that many left and we need them to keep reading. Or I'm an eight year old the interthal in naked lady. Yeah,

here's a naked buffalo for your pleasure. Uh. There's also lots of theories that these things were um supernatural somehow, like they were trying to invoke the animal spirit for a successful hunt or gain some sort of power by creating an image of the animal. Um. And it could have also just been like this is what I see in my everyday life, and I have this desire to create art. So that's that's the subject I'm gonna make is this animal that I am thinking about a lot

because I have to hunt it for sustenance. Yeah, that makes a conversion between this innate desire and the everyday life. And that's bison on cave walls. Well, some of them are pretty detailed in uh, some are life size. It's like they really took a lot of time. It wasn't something they just dashed off in a matter of hours.

And they're using these torches too, are not like it's not like a modern electric torch known as a flashlight also, but um, they're like stone torches with like a little divid in the top and some animal fat put in there and then they light the animal fat, which I'm sure in and of itself is quite a task. Um. But so yeah, there was there was a lot of effort put into this, a lot of detail. Gathering the pigments I'm sure wasn't an easy feat, especially if you're

doing like a life side bison. How long did it take to gather all that? Ochre sure it's not a quick thing. And it's not just paintings. They found a jewelry and other like engrave, bone and ivory and they think they probably engraved wood too, but that obviously wouldn't survive that long. But um, they suggest early religious belief and that they think they might have buried people with some of these things. Yeah, so it's like it's amazing stuff.

And unfortunately when there's no written history, there's a lot of speculation. But it just I don't know, it's fascinating to me. Well, yeah, you know, and their their history has been largely lost. It just happens to be preserved

in the caves. But since they weren't just as strictly cave dwelling society, we're only seeing a portion of their culture, right, because the rest of it was in animal skin shelters and earthen lean too that have been totally lost because they were exposed to the elements the caves that were flooded out and washed away too. So yeah, well that's why there's only like, well, there's more than that, but the two big daddies, there's only two. No, there's another one.

There's one called Altamira in Spain. Yet Steely Dan had a song about it, the Caves of Altamira, and is it loaded with art? Okay, yeah, there's there's plenty more than that. It's just less goes the most famous one, and then chauve is the most recent, most famous one because I heard but there are others. Um, what about rocolodytes. We should mention that that's a great word to call somebody. It always reminds me of trilobite. Remember the little weird

kind of insect, armor plated fossilized insect. I'll show you a trilobite. It was one of the earliest, like footed animals. Scary looking really, but that's what I always get the too confused chocolate. It means cave dweller, literally someone who lives in a hole or cave named after There are apparently some West African tribes that the Greeks came in contact with, and they lived in cliff caves, and they

were called trogold eye, t r trougled diet. Well, it's a nice insult you can throw around these days and sounds sort of intelligent. Instead of calling someone like a d bag, he'd say he's a trocolodyte. Yeah, you know, yeah, and one got Jerry. Two man, you guys are on the same wave like today, I guess so shot, so I guess we can fast forward down to the present day. Yes,

well modern, let's not quite go into present day. I think we need to give a shout out to the Anasazeing and the Pueblos word cliff dwelling people's from the twelfth century ish of the southwestern United States who basically showed up and started carving into cliff faces, carving out caves and lived there. They built their own caves. Yeah,

you should see some of these. Look up, like, just look up cliff dwellers US and you'll see some really neat They had, like whole cities like carved out into these these cliff faces that you could only reach by ladders. That sounds really dangerous it was, but it was also very well defended and sertified. Yeah, because people just be like, I'm not going up there. Ify those guys. Yeah, I'm not climbing that ladder. It's crazy. Um. Can we talk

about Mountain Mountain Hebron Are we there yet? Yeah? Okay, Uh, that's in the West Bank in the Middle East, and a lot of clan of Palestinians live in this network of caves that have been around for about a hundred years that their forefathers built and uh, but of course, because it's in the West Bank, there's UH some disagreement over who should be there. Of course, it's been claimed by Israeli settlers as well, and the army has threatened to remove the people. I don't know what the current

state is. I looked it up, I couldn't find it. Last I saw was that they basically designated it a militarized zone, which meant that the Palestinians living there needed to leave. But are they still in there? I don't know that. The most recent thing I can find from two thousand five, so I don't know alright, Well, southern Spain, was that what you were talking about. I don't know if Faltemyer's in southern Spain, but there's it's definitely in Spain.

But there are like a natural cliff or cave dwellings that were carved out into even further cave dwellings in Spain and um have basically been continuously inhabited at one time or another. Now there's a large homeless population there apparently, right. I mean, Spain's got like unemployment. I'm sure that the cave dwelling populations increased proportionately. Uh, Cappaduct. Cappadocia uh in Turkey has an elaborate cave system and it's not a

very friendly place. There's not a lot of vegetation that's been described as lunar and yeah, it's amazing, it's really amazing. Just the natural landscape itself is amazing. And then if you look closely, you're like, oh, those pock marks are caves like homes. Yeah, and these were man made. These were carved out for people to live in, which is um. I guess we didn't even say. I guess that's the other type of cave. You neither find one or you

can make one. But yeah, and by making one, I think anytime you kind of enhance or extend a natural cave to that's that was account. I would guess that'd be man made too. Yeah, probably so. But the in Cappadocia in Turkey um anchor rights, which were early Christians who were your hermits. Yeah. Um, they inhabited these caves and and made the first dwellings. And then when the

Christians were persecuted, they were joined by a lot more people. Yeah, and they actually built um underground churches that became an underground city have you seen these pictures? Oh, they're amazing, just the masonry and the artwork that they made of just hewn from the rock. That's still intact today. And apparently it was abandoned and then forgotten for a while and then rediscovered. Not but that was pretty neat to find. Well, I got another documentary for you, UM, like no place

on earth have you seen that one? Uh? There was a guy a caver that UM was exploring this cave in the Ukraine and he found like shoes and medicine bottles and things, and he was like, wait a minute, this isn't like paleolithic at all. This looks like it was from the nineteen forties. And it was. And it turns out there was um thirty eighth members of different Jewish families hid in this cave during the Holocaust for h five hundred and eleven days. They lived underground for

over a year and a half. And and uh, some of these people are still alive and they found them. They still live in the caves. No, no, no, no, they lived there for a year and a half. I got you in the Holocaust, Um, but there they had never told their story. They just like kept it a secret. Because they were like, no one would believe it. Plus also in case they ever needed to go back to the caves, Well they did go back. They took him

back to the caves. No, I'm saying if they ever had to go back to the cave, like you want to keep the cave secret because they weren't the first time, you know, but um, it's pretty powerful. And they take some of these survivors back to this cave or they haven't been since the Holocaust and they all survived to um, really really great documentary. That's cool. Yeah, very cool, like no place selves, like like no place on Earth or

like no place selse Um. There's also apparently a trend in parts of Europe to buy old man made cave homes and dress him up. I saw this and I was like, really, I didn't double check, but I could see this. Yeah, I mean this is a grabster. So's he's good on his facts. Outfitting them with electricity, um, installing modern plumbing, uh, getting the ventilation system going, and just turning it into a vacation home. Yeah, putting down

tile floor and there's always the cave home weirdos. Yeah. Well, I mean, if you're seen the show TV, like you know, bizarre houses. If you're a green person, yeah, you could do a lot worse than build yourself a cave home because the environmental impact is so much lower. It requires much fewer building materials. Um. If you can deal with very low natural light and not go crazy, then a cave might be suited for you. If you can deal with the damp and moisture, cave might be suited for you. Yeah.

And I shouldn't have said weirdos to eat the throne. But anytime I see those shows of like extreme bizarre homes, you just shoot the TV. This guy made a house out of like Bob Goolay was on it. Yeah, pretty much. Um, I've never been in like there was a cave house near us growing up. Actually that really Yeah. It was like you know, it was when they built into the side of you know Earth where in Stone Mountain is it's still there, I assume, so is it built into

Stone Mountain? No? No, no, no, um. And it was like kind of the people would go by there and look at it and stuff. And I, even as a kid, I thought it was kind of dumb. Did you ever know Jack McBrier when you were younger Kenneth from UM thirty Rock. He's from Stone Mountain Conyers. Oh really yeah, in the show he's from Stone Mountain. UM. One of the other writers for thirty Rock, though I can't remember his name, is is I think what you read in is that right? But no, Hun didn't? No Jack Prayer?

Uh you got anything else? Oh? Yeah? The last thing. One of the other benefits of um cave home it's very difficult to break into, which is sad because that is not the reason why they were initially used in the Paleolithic Carrott. But it's a it's a quality point, now that's true. How far god, where was it that guy that built a house underground? No, I've seen those before. I've seen like missile silos converted into homes and things

like that. This one was for sale recently. I can't remember who sent it to me, but he basically built It's not like a weird, you know, silo house. It's like a home. He just built underground. Like when you go down there. He's got paintings of the outside world on all the walls. It was this rich guy who built it. I think as a like a shelter in

case something bad. Happened. And so you know there's pictures of like rolling fields and when you're underground, I mean, obviously you can tell it's a painting, but it doesn't feel like some cave. It's like just a regular house built underground. Well, there's a theory that we're going to end up living underground because eventually arable crop lay and will become so valuable that we will, uh, we'll all have will basically be forced to inhabit the opposite of

sky scrapers. They will be going downs of up because we'll need the land up on top for crops. Didn't we do one on why why don't humans live underground? Yeah? I guess I could be part four? Then I guess so it's not really a cave. Yeah, that's true. You know this is the cave suite. All right, So let's see you don't have anything else. I got nothing else. If you want to learn more about cave dwellers, you can type cave dwellers into the search part how stuff

works dot Com. And I said search parts means it's time for listener mail. I'm gonna call this. We keep making the same mistake with acceleration. Oh yeah, and I'm tired of it. If we ever say this again, I'm gonna like put us both in time out. Do you think Jerry would be paying attention? But I don't know

why we keep making this mistake. But in the Solar Sales episode, we talked about the fact I think it was you this time said something about the acceleration will kill you, or the speed will kill you, or something going that fast. Yeah, I'm sure it was me. We got a lot of emails and this was one of the nicer ones. Heads up guys on a few things, including on the Solar sales. There's been some misunderstanding between speed and acceleration. Common belief is it traveling at high

speeds is taxing on the body. Not true. It is the acceleration and not the speed, which is dangerous. Take as an example, traveling in a car. Changing your velocity from zero to a hundred kilometers per hour a very short time results in a large acceleration. This is where you get that feeling of being crushed into your seat. But once you keep that constant speed, that feeling goes away. The same thing for a plane. Notice when you accelerate on the tarmac, it's pretty intense, but once you're up

in the air, you barely feel a thing. Yeah, you think we'd know this. I mean, we've done sorts of research on the rockets led an acceleration, and it's just misspeaking in the moment. We know this. Oh, if I'm interrupt for a second. I ran across this designer's euthanasia roller coaster. What um? It was basically this guy design It's all conceptual, obviously a slightly tongue in cheek, but it was designed to kill you, like the roller coaster

was designed and to go out with a thrill. Yeah, and he he describes like what like at what point you will die and from what Basically it's like you are going upside down so fast. The acceleration is so great that it basically like keeps your heart from pumping. Wow. Um, and just to make sure you're dead. He added like six of those loops. But it starts with this huge hill. I can't remember what it's called. I think if you look up youthan Asia roller coaster, this this guy's design

will come up. It's pretty interesting, interesting, but it would be from acceleration, not speed. Wow, that's a lot of work to put into a killing machine. I would just draw a length of rope and a sturdy beam. You know, Um, you wouldn't be a successful designer, probably so. Uh So. Then he puts it in the context of the solar sale um and says only very small accelerations are involved, so human traveling in such a ship would experience minimal forces. So I hope it clears it up a little bit.

Definitely rocking guys, Thanks a lot. That is from knee RAJ from Australia slash Mauritius ni Raj. Thank you if you appreciate that. We will never make that mistake again. I disagree. I'm sure we will. Speed'll kill you. Where's Northern Ireland, Great Britain, UK England? We've been getting that one wrong forever too. Yeah. You know, there's only so much information a human brain can hold, everybody, and we're trying to fill it with things like cave dwelling backs

and stuff like that. Yeah. Who was the bass player for Poison? I can't get rid of that, do you know that? Yeah? Bobby Doll, So there's cc It was the guitarist Brett Michael Frett Michael. Bobby Doll is the guy. He sounds like a seven oriole or something that the drummer was. You remember him, right, No, Ricky Rockett? Oh wow, yeah, no I do. I didn't even like poison. That's what's so funny. Poison was good. I wouldn't have fan they

were good. Uh, let's see. If you want to know more about poison, I had to do that part, didn't I sure. If you want to get in touch with us, how about that. You can tweet to us at s y s K podcast.
