Speaker 1 (00:01):
Welcome to Stuff you Should Know from house Stuff Works
dot com. Hey, and welcome to the podcast. I'm Josh
Clark with Charles W. Chuck Bryant. Jerry's doing funny voices
all of a sudden. Yes, She's like, we're eight years
into this gig. I'm gonna start doing impressions. I know.
(00:25):
I don't know if it's an impression, it's more just
a silly, silly, dumb voice. Maybe she's taking on a
stand up class or improv class. Are you taking an
improv class? Jerry? Yes, she keeps going and she says
it's not a comedy improv class, so it's a business
improv class, just to make her sharper in meanings, you know,
and they have gotten much more enjoyable and shorter. Yeah.
(00:49):
Her power point presentations are like one third jokes now. Yeah,
but our equipment rental has gone up purchases because she
drops the mic a little too hard. Yeah, just keep
her place in those mics. Yeah. So, Chuck, everybody knows
about the pyramids, great Pyramids at Giza. Turns out there's
pyramids all over the world, and there's a a distinct
(01:14):
thread on the Internet that suggests that all these pyramids
are connected in Mesoamerica, China, Egypt, Memphis, Greece, Memphis in Egypt,
not Memphis, Tennessee. Is there, Well, it's one of these
new pyramids, a neo pyramid. It's a basketball Colisseum, okay,
(01:36):
oh yeah, yeah, the pyramid. Sure? What is that a
mud island or something? Is that a different island in Memphis. Well?
The the idea is that all of these cultures, ancient cultures,
were visited by the same aliens that said, built some pyramids,
here's how to do it, we'll help you out. And um,
(01:56):
that's just almost certainly not sure. Yeah, I feel safe
in saying, as much as I like to believe in
cookie things, I don't believe that the aliens built the pyramids.
I don't believe that either. And one there's a couple
of good arguments against it. For for one, it really
diminishes the incredible skill of the ancient engineers who came
(02:19):
up with us and the workers who constructed them. It's
like the architecture the Yeah, surely they would need some
advanced alien civilization to come down and tell these dumb
dumbs what to do. And then another point that I
ran across That kind of explains against that is that
if you I think it was unlike rational wiki or
something like that, they basically said, go out in your
(02:41):
garden and try to build a waste high mound of dirt.
He said, you're going to just naturally after even one
or two attempts, start forming a pyramid of mound shape,
and their whole jam. The whole idea is that pyramids
evolved independently just from trying to build a massive earthen structure. Yeah,
(03:03):
and there you go. That's where pyramids evolved separately around
the world. I was laughing because as soon as you
said that, for some reason, I pictured you in your backyard,
like covered in dirt, just screaming like you it's not
going well, call somebody check the wrong besought the list
doesn't hold up, and you mean he's like on her
phone like what you Okay, you're cute, keep it up.
(03:25):
Uh So a pyramid um who wrote this one? Is
this some Craig Freud and Rich PhD? Yeah, he's written
some good ones for us. I've learned to not second
guess his articles. You know, Yeah, No, he's he's good.
And you throw a PhD at the end of your name, right,
you're not allowed to second guess that. After that, how
(03:45):
might just start doing that? Nobody checks, you know, call
me doctor Chuck Charles Bryant, PhD. Yeah, um, alright. A
pyramid is a geometrical solid with a square basse, not
necessarily and for equal our old triangular sides, the most
structurally stable shape for projects involving large amounts of stone
or masonry. Exactly, it's a very very stable shape. Yeah.
(04:08):
And one thing I read that said why did the
Egyptians build pyramids? The very easy answer is is because
that's what they knew how to build. Yeah, Well, they
were good at it, and if they would have been
better at building something else, they probably would have built
something else. Well. Yeah, I think Also it took until
um the well about the twentieth century before we started
(04:31):
using materials and developed materials that you you could build
a very tall structure out of that didn't require you
build a pyramid, because you have to have a pyramid
to build something very high. When you're using something like
stone blocks or something like that, you keep setting stuff
on top of each other and it's going to become
structurally unsound once it's all leaning in on each other,
(04:55):
and the prevailing um sentiment among archaeologists and anthrop copologists
to study this kind of stuff is that pyramids are
ultimately the natural um conclusion evolution from just earthen mounds
that they think originally were the first stabs at what
(05:19):
ultimately became pyramids, peaking basically at the Pyramid of Cufu. Yeah,
and they I think there's also probably symbolic, uh, some
symbolism going on with pyramids coming to a point towards
the sky. Uh. In the case of Uh, let's say
Central America with the minds and the Aztecs, there were
more religious imples, so that it's okay for that, and
(05:43):
if in case of Egypt, with being a tomb, it
also makes sense that it would point toward the heavens well.
With each specifically, they believe that the symbols, the symbolism
behind the pyramid is that it symbolized this mound that
the earth was created from in Egyptian cosmology. Yeah, that
makes sense. Yeah. Um. So the other are a couple
(06:04):
of other distinctions between Egyptian pyramids and let's say Central
American is Central American pyramids were generally wider but smaller
as I guess not as tall and um they built
those over hundreds of years, whereas the Great Pyramids and
Egypt were built over the course of you don't know
for sure, but probably twenty or thirty years. So I
(06:25):
think that that's true in some cases. But I ran
across something that that suggested that at umtan Um they
would build pairs of pyramids like every twenty years. Yeah,
So I don't know if it's the case across the board,
but I think that they weren't quite the massive public
works that Egyptian Pyramids came to be. Yeah. Well, in
(06:48):
Central America, they were also more located in Aztec in
mind cities, whereas the Egyptian Pyramids originally we're located away
from cities. And I remember, I think it was just
last year that I saw that mind blowing picture of
the other side of the Great Pyramids of Egypt. How
the city runs right up to the front door basically,
(07:10):
and if you ever look at an aerial of view,
I've just never seen one until a year ago. I
was like, Wow, I just thought it was literally in
the middle of nowhere and there's a huge city just
right in front of them. Yeah, and well it makes
sense though, if you think about it, especially if saying Mesoamerica,
they were temples. Well, temples were for like public use,
so you'd want it kind of convenient if you're pyramid
was used as like a tomb. Humans traditionally bury their
(07:34):
people slightly away from, you know, their city center, so
it makes sense that it would be on the outskirts
of Cairo rather than in it. Yeah, that makes sense.
The first tombs in Egypt for the pharaohs were just flat,
boxy buildings. They called them mustabas, which is Arabic for bench,
(07:54):
and then they started building those on top of each
other sort of in the uh, you know, they get
a little smaller, but they still remained flat on top.
They didn't come to a point like a pyramid. Yeah,
those were step pyramids, and they were the first attempt
at pyramids. And it's um, it's really strange because the
whole thing was so these pyramids are so so old
that you think of them just like being you know,
(08:17):
spanning thousands of years in the way of construction and
planning and all this stuff, and all the number of
pharaohs that must have been involved when actually um, Egypt's
Egypt's pyramids were built within a seven year period and
basically just for like five pharaohs or so. Yeah, it's
not too bad. Yeah, it was like there's a burst
(08:40):
and then nothing, and then another little bit and then
nothing after that because it's hard labor. It was hard. Yeah,
it was hard getting labor there. It was hard. Um,
it was very expensive. It's hard getting those rocks there.
And they also think, remember I said that um Cufu's
pyramid the most famous pyramid in the world, the one
as of the tallest one, Um that that was the
(09:03):
pinnacle of pyramid building. And they think that after that,
as pyramids started to get smaller and something like that,
totally unintentioned, they think that as pyramids started to get smaller,
it actually represents a shift in Egyptian thought where worship
went from worshiping the pharaoh to worshiping raw and other
gods Um, so that the deification of the pharaoh diminished
(09:28):
in size, and you can see that reflected in the
smaller size of the literally. Yeah, interesting, that makes sense.
I never heard of that. Love it. I love it too.
So the Great Pyramid of Cufu, which you just mentioned,
is the biggest at a hundred and forty six ms
high with a two d and thirty meter square base
and oh, just about six and a half tons of
(09:52):
rock six and a half million tons. What did I say,
just six and a half Yeah, that would be that'd
just be a couple of the rocks. Yeah. I think
the average side rocks were two point five tons each.
The model was six point five tons, right, Um, And
these things have stood at the test of time, to
say the least. They have worn away some obviously, but
(10:13):
look at them. They still look great. Yeah. And they
were built like four to five thousand years ago. Yeah.
What's really interesting that I didn't realize before was that
when you saw these things, like in the first year
that they were completed, or right when they were completed, um,
they were blinding white. Oh really yeah, So you can
(10:34):
see like this, the step, the steppy outline. They used
to be covered so that the sides and the pinnacle
were smooth, totally smooth, covered in polished limestone. So it
was like a gleaming white standing out against like the
bright blue sky, which there were photographs of that. Yeah,
it would have been pretty neat. But over time that
limestone is eroded away or being removed or whatever. Um,
(10:57):
And so now you can kind of see the substructure.
But what we see is like the external sides of
the pyramid were actually meant to be covered with polished limestone. Wow. Yeah,
but that was something else. And again we're talking about
like how spectacular feet this this was engineering wise. Things
were built, you know, forty years ago. Let's say, Um,
(11:18):
the Cufu Pyramid, Cufoo's pyramid. He was a pharaoh. Um
his pyramid was the tallest building in the world until
the twentieth century. That's crazy. Yeah, I mean that just
shows you that it was hard to build things tall. Yeah.
It's not like people didn't want to know. They wanted to.
I think man is always uh. Striven Strove stroded Strove
(11:42):
did strid to build things super tall, you know, uh,
to really reach up to the heavens and punch God
in the eye. Yeah, that's right, that's the that's why
they want to build it tall. That's right. Uh. The
very first stepped pyramid, Uh, the Sakara was completed in
(12:02):
and that was for the pharaoh. Jo's Er not Gozer.
It seems pretty close to that. It's so close. I
wanted to be Gozer. He would have been almost contemporaneous
that gozer, I would guess. So this one had six
levels and they tried, um, they attempted another one, another
six level step pyramid, but that one didn't work out
(12:23):
so well. So like you know, we're going to talk
about a couple of that, you know, learning projects basically. Yeah,
and you know you've heard a very famous um Egyptian
mathematician m Hotep. Yeah, he's actually credited with coming up
with the idea of taking those mastabas, those bench like
squat buildings and stacking smaller and diminishing versions of themselves
(12:46):
to create that first step pyramid, that first zigaratte that
that was his idea, and um Bubba Hotep, No, not
that that was a good movie, m Hotel, m Hotep,
I had no idea. By the way, that Bruce Campbell
was doing an Evil Dead TV show. Is it on? Yeah,
it's coming like it's super soon. I have no idea
(13:07):
how this escaped me. I had no idea either. Yeah,
I'm pretty excited though it's just back. The only way
it could be better is if it came on right
after the Muppets up Pretty good Night. That'd be like
the A Team Night Writer pairing. M hmm, was that well,
I was back to back. I think they might have been.
I was never in the night Rider, so I turned
(13:28):
it off after it. I wasn't the Soups night Rider fan.
But all right, let's go with Love Boat Fancy Island,
maybe the best two hour pairing in TV history. I
never really watched the Fantasy Island. I loved Love both.
I wasn't allowed to watch Fantasy Island. Well, no, I
had the word fantasy in the title. We don't want that.
Um No, I think it was. It was dark and
(13:50):
it wasn't necessarily for kids. But now when I look
back at it was so silly, Like, I can't believe
I wasn't allowed to watch this. Well, the whole premise
of it is just fairly unbelievable. But at Mike Family
they were probably like, no, it's it's all about sex.
Everyone's fantasy will be about sex. And Ricardo montebon is
clearly playing the devil. Yeah with this little, uh smaller minion.
(14:15):
All right, uh? Where were we? Oh, we were talking
about pyramids. It didn't work out so well. Another one
was the I want to say medium, but it's the
me edam pyramid or the medium. I've also seen it
spelled emmy y do you m, which makes it easier.
It's like made him made him made um that was
(14:36):
constructed seventy and it had seven steps, uh, heading towards eight,
but it collapsed. It collap And then there's the bent pyramid,
which didn't collapse, but they they basically just miscalculated the
angle and it started to They basically had to change
(14:56):
the angle after like the first third of it was
built or two thirds was built. Yeah, So first we
have dozers Gozer's um step pyramid in Sakara. That's the
first real inkling of that pyramids are coming. After that,
we had the pharaoh um oh what his name, Snifferu
(15:19):
Snifferu and Snifferi was the one who kept having really
bad luck with pyramids, and it was because he was
very ambitious, but he was also um dealing with architects
and engineers who were still figuring this out as they
were going along. So he had to put up with them.
The one that collapsed the meat made him yep, and
(15:42):
then he had to put up with the bent pyramid,
which still looks good. Did you look it up? Yeah,
it's it's great, but you can tell, like it's not
the way it's supposed to look perfect like, and I
can imagine like a lot of engineers probably lost their
lives with these failed projects because sniff Uru or snaff
Au he was fine with like capturing people and forcing
(16:05):
them to work, and he did a lot of underhanded
things to build himself a tomb, and the problem was
this failed attempt one how many decades did that take?
Failed attempt to how many decades did that take? Finally,
and they're like really freaking out at this point, like
if this guy dies and we don't have him a tomb,
(16:25):
like like this is about as bad as it could
get because I remember, we haven't converted to worshiping raw yet.
This guy's are raw, so we're dis pleasing our god
and we can see his expression just all I want
is a straight pyramid like everybody else. So finally they
hit on it. They build him the Red Pyramid, and
it is the first genuinely successful pyramid, and he died happy.
(16:50):
I guess, yeah, And I assume wasn't tombed there, Yes,
I think so, I don't know. I didn't run across
that where he is. I Belu was otherwise that would
have been I mean, what a waste of time. Well,
that's the thing with these pyramids, we still um have
very little understanding about some really important stuff. Yeah, and
(17:14):
one of the reasons why is because they like in
Cufou's pyramid, Couper has never been found in there. They
think it's Coufu's pyramid, but his body's gone. And I
would guess probably the same thing for sniff sniff Au man,
he's got a tough name to say, Tom Rador's buddy. Yeah,
possibly probably. All right, Well, I think that you seriously
(17:37):
wet the listeners appetite with that tease. So let's take
a little break and come back and really get into Cufu.
(18:01):
Al Right, buddy, we might as well just go to
the big daddy and break it down. Cufu, break it
down for me, fellas k h u f U also
known as Cheops. Oh yeah, yeah, that's what the Greeks
called them. H So that's why the pyramids also called
the Pyramid of Cheops. I've never heard that um part
(18:22):
of the Giza pyramid complex. And like we mentioned, the
big daddy of them all, uh, it was built for
sniff AU's son Cufu and the other two little guys
were built for Cafu son uh cofre and the grandson.
Uh minkow ray. I'll bet it's manka manka ray. Yeah.
(18:44):
I think usually those vowels are split to like a
different part of the word man Making any sense you
are to me, But I know what you're trying to say,
I speak chuck, that's right. Uh So it is um
the largest and most elaborate in the one, you know,
where we've learned the most from basically in its construction.
(19:07):
Still has a lot of secrets, man, a lot of secrets,
including how they built it. Yeah, no idea. Well, let's
talk about the insides first. Let's sorry the guts. Uh. First,
you have your primary burial chamber. That's the King's chamber,
and that's where the tomb is. That's where the sarcophagus is.
Body in there. No, nope, What else is inside? Chuck?
(19:30):
Um hieroglyphics that say tell stories of life at that time, right,
you know, like little TV shows on the wall. Um.
The queen's chamber a little smaller, but not for the queen.
Is that right? That's right? They call that a misnomer. Yeah, Um,
Apparently people who stumbled upon it or entered it years
(19:54):
and years on after the Faronic dynasties had died out
um misinterpreted it and that when they were building this
they were worried that Cufu was going to die. So
some of the first things they did were building burial chambers,
and then as he lived in the pyramid kept going
under construction, they built a newer, better burial chamber, and
(20:18):
so there's ultimately three burial chambers, and he's in the
king's chamber supposedly that's where a psychophagus is. That's right. Uh,
you have weight relieving chambers. These are above the king's
chambers and their structural um basically to distribute weight and
to keep everything from collapsing in on the king. Yeah,
because that would be bad too. Yeah. They're like these
(20:39):
long slabs and then there's a gable. So there's like
long rectangular slabs. I think there's four or five of
them maybe, and then a wooden gable is it wouldn't
I thought it was rock. And the whole thing is
it's like all that pressure that's pushing down towards the
center of the triangle, it takes it and just kind
of deflects it outward away from that hole in the inside.
(21:03):
The um, the pyramid, the feat of engineering. Um. The
gallery is a big passageway with a vaulted ceiling. Um.
Do you understand what the corbelled ceiling is? Yeah? So
you know, like if you have a like a breakfast bar,
those two things that come out and hold it up,
those are corbells. So they had these things that are
(21:25):
like corbell's going up and basically it says here that
forms like a primitive arch. Okay, that makes sense. Yeah. Um,
you have passageways connecting everything because you have to get around.
You have an air shaft where they think the uh,
the spirit of those into him there would rise through
to the heavens. I guess the ideas you don't want
(21:46):
to fully enclose a tomb or a pyramid, gotta let
the soul out, sure, but creep out what else? Well?
Of course the exterior rocks that have eroded away. Sure,
and apparently the reason why we're quite sure that all
these things were aligned with limestone rocks is because Cafres
(22:08):
tomb uh Sneferus Snifferu's great grandson, there's still some limestone
rock on the top. Oh nice, that hasn't fully eroded, man,
after all these years. Yeah, so these are the things
that have been found over the over the years of
exploring these pyramids, right, But what really kind of surprised
(22:32):
me was that there's a lot of stuff that is
still being found. There's a lot of parts inside of
the pyramids that they're like, what is this or why
is there a door in this passage with some copper handles?
What's beyond it? Now? Is this because they haven't fully
excavated Yeah, okay, so they're still doing this. Oh yeah, yeah, yeah.
(22:57):
The um I can't remember his name, but the former
head of Egypt's antiquities before the revolution, um I can't remember.
He's like super like science educator guy. They call him
India Egypt's Indiana Jones. Okay, I thought you gonna say
Neil the grass Tyson. He's like Egypt's Neil de grass Tyson.
(23:17):
He could host Cosmos if you wanted to. He um
he is. He's been walking around lately saying, hey, there's
plenty of undiscovered stuff in these pyramids. We have a
very loose grasp the structure of them so far. Well,
and it's tough to get in there to do the work. Um,
I know the permitting process and is rigorous obviously, so
(23:39):
it's it's it's hard to know. This guy we're gonna
talk about later that has a new theory on how
they're built, he's having a hard time getting in there
to prove it. Yeah, but luckily they're starting to use
robots more and more to explore it, and that's starting
to yield some some interesting stuff. Did not know that either.
All right, well let's um, if you're gonna build a pyramid, Uh,
(24:00):
you don't just say let's get a bunch of rocks
and start going. Um. First, like any building, you need
to do a survey and excavate the land. Because they
learned pretty early on that you're the land that it's on,
and the foundation is super super duper important. Yeah, that's
I think one of the reasons the first one collapse
(24:20):
is because they didn't do the foundation right. It's got
to be level and again it's kind of in part
how impressive the cufu's pyramid is. What did you say,
it's um it's base was it is a two hundred
and thirty meter square base. Yeah, it's level within less
than an inch. Yeah, that's remarkable. So you get the busier,
(24:45):
the master builder involved. And they do have some theories
on how they did this leveling. UM. One was that
they poured water onto the site, and water is the
great leveler, and they would level the material above it,
above that water line, wait for the water level to drain,
I guess, and then just continue removing material until it
(25:07):
was flat. Great idea. Yeah, and it's like, you know,
self leveling concrete is way more soupy than uh, like
regular concrete, because it's gonna find if it's watery, it's
gonna find its own level, right all right. Uh. And
then another way that they may have done it is
so they found that um their post holes at regular
(25:29):
intervals of I think ten cubits, and a cubit is
the distance from the your elbow inside your arm to
the tip of your middle finger, so every ten of
those there would be a post hole. And they think
that possibly they laid out the foundation site as they
were excavating, into a grid pattern and hung plumb bobs
(25:52):
from these lines. And that's just like a weight that
looks like um, like an elongated brass top and it
hangs down and where it hangs is the level point,
and then you can excavate down to that that reference point,
and then you know everything's level if all of your
plumb bobs are touching the same ground. Yeah, and that's
(26:12):
still like if you go to build a backyard fence yourself,
you're gonna use these same techniques today. Right, it's pretty neat.
My money's on the water excavation. They they we already
know that they dug canals from the Nile toward the
Giza pyramid sites. Why not just built a little further
and flood the area as needed to excavate. You know,
(26:32):
that makes sense. That's that's a minus. But first, Chuck,
they had to figure out because these pyramids are all
oriented along um north south east west right. Yeah, they
run parallel to these xs, so like they're there, I
believe they're facing true north. This is pre compass, its
pre north star. Yeah, the north star wasn't even the
(26:55):
sky there then. Um. Instead, they had to follow some
of the circumpolar star and they were doing things like
measuring shadows to calculate where true north was. And then
once they calculated true north, they could use right angles
to determine where uh, southeast and west were that's amazing.
And then once they had that, then they had to
(27:15):
start doing the planning out the site in a grid
and excavating everything down. That's right. Uh. Using cubits and
hands was the other unit of measurement, which is, uh,
you say something so many hands wide, it's the width
of your hand with your thumb along the side. Yeah,
And they still use that to um measure horses or
to describe horse heights, like twenty hands high. That's a
(27:38):
that's decent height with it's at a big horse or
small horse hands. I think that might be like a
giant freak of nature horse. Yeah. I usually here like
fourteen or sixteen. Hey, that's off to the triple ground winner, right, Yeah.
American Pharaoh whoa which, by the way, Pharaoh was misspelled
in his name, and they knew it early on, but
(27:59):
they were like, well, we're just gonna leave it like that.
Um so pharaoh. Yeah, pretty neat history. That was pretty great. Yeah.
I watched Um, I did watch that, and you know,
I'm not into horse racing, but I knew what was
coming on and I was like, well, it's only a
few minutes, so I just don't watch any of the
other stuff of the two hour podcast, and I just
(28:22):
turned it on to hear that call. You know, it's
always great here in a good horse racing call. That
thing led the whole way. Yeah, there was really no doubt.
And I love that jockey. Yeah, because he had he
had had several attempts right at the time. He raced
California Chrome last year, so we had a shot at
the Triple Crown and I couldn't pull it out. And
this year he did good for him, all right, So
(28:46):
I guess we should talk about how they actually build
these things. Now, you gotta get rocks there, that's the
first step. Yeah, and some of the rock did come
from Giza, like the rocks. The pyramid structure itself is
made largely of limes stone, and there was limestone quarries
around the Giza site. But they also had to get
rocks from elsewhere. Yeah. The granite they think came up
(29:09):
the river from a swan. They have alabaster from lux
or basalt from the Phioum Depression, which I didn't see
where the basil was used, however, it's pronounced by salt
is it? I don't know, um, And of course you
know they don't have iron at this point, so they're
(29:30):
not using iron to cut. They're using copper and stone
cutting tools to shape these things. But you have to
get them there, which is you know, I think of
the neatest thing about the Pyramids is over the years
is trying to figure out how they did it all
because they didn't leave a record. Um, you know, it's
just been this great mystery for architecture and archaeological nerds
to try and figure out. Yeah. So the first step
(29:52):
is like, all right, well, how did they get all
these rocks here to begin with? So? Um Again, these
rocks were on average about two and a half tons
per rock. Yeah, so they didn't just lift them and
carry them. No, the Gypsies were familiar with the wheel,
but the wheel would have been totally useless in the
sand at Giza. Um, so they figure. I think the
general sentiment of how they moved rocks, especially once from
(30:15):
local quarries at Giza was by sled and rope. And
they had um, maybe ten men or fewer if they
could um pull these uh two and a half ton
rocks on sleds towards the site. So that's how they
would have moved them from the quarry. If they were
moving them from like lux Or or elsewhere, they would
have put them on rafts. And again they dug canals
(30:38):
from the Nile towards the Giza construction site. I bet
people loved being on that duty. Like the raft one well, yeah,
like just get it on this barge and then float it.
And the other guys were like, are you kidding me?
I have to pull this thing on the sand sled.
And then there's another way that um that they think.
They may have put them on little quarter circle sleds,
(31:02):
strapped them around it and just kind of twisted them
like you would twist a beer keg. Yeah, yeah, that
makes sense too. I would guess flat sleds. Although why
does it have to just be one or the other? Well,
that was what I was wondering when I was reading this.
It could have been a combination of methods. Yeah, Like
these guys are sled masters, so let them do that, right.
These guys have rolled a beer keg or two in
(31:22):
their day, so they can try that method. They've also
theorized about wooden rollers like logs and things. Makes sense.
The only problem is is um Timber was not a
local commodity. Yeah, that would that would have been widespread
enough to supply this thing, and it would have been
very expensive well, which is another reason, because they have
some super weighty timber on the interior of these pyramids,
(31:47):
and they also have wondered about that. I think it's
probably cedar from Lebanon. That's what I kept coming across
that the would that they were known to have used
was from Lebanon and it was cedar an e seater.
I bet that's good stuff. It was expensive back in
the day. Um. So when it comes to actually building
(32:08):
the pyramid itself, you've got so you've managed to get
all the rocks here. Um, you know what, we'll take
a break and we will talk a little bit about
some of the competing theories right after this. All right,
(32:35):
you got all your rocks. You're the foreman, you're the
what's it called, the the visier. You're the visier on
site who, by the way, Cufu's visier was his brother. Yeah. Yeah,
And if you were a visier, like you were pretty
well respecting, you've got your own little step pyramid tomb yourself. Sure,
So let's say you're that person. You've got your little
(32:55):
hard head on. You've got all these rocks, how do
you What are the theories they use like a pulley,
they use a crane. Uh well, there are a lot
of competing theories and they do involve cranes, they involve ramps, um,
and none of them have been proven. So let's talk
about like the ramp. One man, they figured out that
(33:16):
with a ramp you can't have when you're dealing with
two and a half ton of stones. And this is
from how to Build a Pyramid, which is from I
think a two thousand seven article in Archaeology magazine. Yeah,
Bob Bryer, it's really good article, it is. It's a
great article. Um. But he points out that you really
can't have a grade of more than about eight percent.
(33:36):
So if you're using a straight ramp leading up to
the pyramid site, as this thing gets taller and taller
and you eventually hit a hundred and forty six meters,
to maintain just an eight percent slope, you would have
to have a mile long ramp at that point. And
they said that's not very likely because that would have
been just as big of an undertaking is building a pyramid. Yeah,
(33:59):
it would have taken up about as along the build
and the timber, like you mentioned a lot of timber,
which they didn't have tons of, and they would have
built built it up over time, because you can't just
have a hundred and forty six ramp to start off
with and then drop the blocks in place below. You
would just slowly build up the ramp, but eventually it
would just become too unwieldy to have a mile long ramp. Yeah.
(34:22):
And we're not the first people to question this. I mean,
thousands of years ago, um people, historians were trying to
figure it out as well. He wrote. He wrote it
us Uh in four fifty b c. Said that they
use machines, but no one really knows what he meant
by machines a lot, but it could be a crane. Uh.
And then three hundred years after that, Deodorus of Sicily
(34:42):
said the construction was affected by mounds, which would be ramps.
So that's why these are the two the two longest
standing competing theories. The problem is is these Greeks came
along thousands of years after the pyramids had already been built.
It's not like they witnessed the construction. They were just
there their Yeah. Um, so with Herodotus or Herodotus, you know,
(35:07):
I don't know. I've seen his name in print so
many times, but I don't think i've ever heard it.
I'd say Herodotus sounds good. Say that, um his idea
of these machines that have been taken to mean cranes.
We know that the Egyptians were familiar with cranes and
use cranes, and that you could use cranes to build
a substantial portion of the pyramids. The problem is, as
(35:28):
you got closer and closer to the top, the leads
you were dealing with is say about eighteen inches, and
you can't support a crane like that. So the they
thought potentially that if they did use cranes, they use
series of small cranes that would just kind of hand
off like basically a bucket brigade of cranes handing off
one rock after the other. They were like levers, and
(35:49):
they were called they use these are called shadoofs um
and if you look up chadoof and image it there.
They would use it to get water out of the
river and stuff. And it's basically like just a lever
that someone would pull on one end or will be
waited and dip down into the water and then pull
up a bunch of stuff with a bucket. I guess, yeah,
a bunch of good Nile River water. Yes. So, like
(36:12):
you said, that theory is not very well excepted these days.
The crane Yeah, well, oh not for completion at least. Yeah,
and again like why just use one method if something
makes this part faster and then you have to switch
to this other part faster. Clearly these people had the
smarts to pull off this incredible feet of engineering. Um,
(36:33):
So I would think that they wouldn't have tunnel vision
and that they would probably be willing to use different techniques.
So it's it's possible that the cranes were used to
build the base. They'd have pyramid vision, right. Uh so
with the ramp, so the big long ramp is probably out. Um,
they had another theory that well, maybe it was like, um,
a ramp that just wound up and around the pyramid
(36:55):
like a mountain road is cut into the side of
the mountain. That sort of makes sense too. It is
the big problem with that is that the mound outside
of the pyramid covers up the corners as you're building it,
and as you're building it. You really need to be
able to measure the corners pretty frequently, because if you don't,
then those corners may not come together at a point
(37:16):
at top and SNIFFERU is going to be very mad, right,
So that one, to me is probably the least likely
the external um ramps. That and co enclose the site agreed. Um.
And maybe I'm a bandwagon ear, but I just read
this article that you sent, and so I'm going with
(37:38):
Jean Pierre Udine's theory that there were ramps, but there
were an external ramp that was the need to be
that long, and then once they got to the point
where the grade was too much, they used that ramp,
cannibalized it, and then had an interior ramp, yeah, to
finish it off, right. So Um, the thing about an
interior ramp is that you would be able to leave
(38:01):
the exterior corners exposed, You'd be able to build inside,
You'll be able to keep it at an eight percent
grade tops um, and you wouldn't have to build this huge,
massive public work that was as big as the pyramid itself,
like a hundred and forty six mile long ramp. It
would explain how you would build the whole thing without cranes,
(38:24):
because you're just getting closer and closer and closer to
the to the inside the interior of it as you're
building up right. Yeah. Um, the only problem is, Chuck,
is if there's an interior ramp, how would you possibly
remove that? You wouldn't it would being closed in the site.
So obviously this has been debunked right, well now it hasn't, um,
(38:45):
he believes and others have gotten on board that there
is still an interior ramp in there. What But that
was my question. Have they not explored enough of this
to find this thing? No? Okay, And actually there was
an nineteen six survey, but I think a French team, um,
and there they found some anomaly that they couldn't explain,
(39:08):
so they just ignored it basically. And it wasn't until
two thousand that Jean Pierre hu Dan's father, Henri hu Dan,
who was an engineer himself, just happened to be chatting
with one of these guys from the nineteen eighties six
survey and um, the guy said like, yeah, there's this
anomaly and he described it to him and basically what
he described as far as the Udans are concerned, is
(39:30):
this internal ramp. They're like, what is it? It's anomally,
it's like a big looks like a big, well worn
ramp right seven degree slope. Who cares. But supposedly the
way that they first discovered this was that a fox
popped out of an undiscovered crevice or previously undiscovered crevice
toward the top of the pyramid or halfway up, and
(39:53):
they're like, how did this desert fox get up there?
Probably did not climb all this way up. They think
he probably went into an other undiscovered hole towards the
bottom and then use the ramp and came out the top.
And that is further evidence that there's a ramp in there. Yeah,
there is another little piece of evidence that they point to.
Um there was a notch, a corner notch from the
(40:15):
ramp used for turning the blocks, and it is exactly
where two thirds of the way up on the northeast corner,
right where Udine predicted there would be one if you
were to use this kind of ramp piece, like, there
should be a notch right there, And there was a notch,
but yeah, I think where the inside right, Yeah, pretty neat. Uh.
(40:35):
And then finally they used um, something called micro uh
grab immetry. It's a it's a I don't even understand
how it works. Do you know? It's a surveying method. Yeah,
it's magic, right, um. And basically what it does is
it enables them to measure density. Yeah. So like if
(40:56):
if you're measuring a part of the pyramid and it's
just solid rock, it's going to be very dense. If
you find a part of the pyramid that's kind of
this open tunnel like a ramp, it's going to be
less tense. So I think that's where that's from that
survey where they turned up the anomaly that they ignored.
That's the impression. I have one other thing that um
(41:20):
it was a very long standing myth thanks to our
friends the Greeks, who just made stuff up apparently two
thousand years after the fact, was that um, it took
about a hundred thousand slaves to build the pyramids at Giza. Yeah,
mistreated um slaves, forced into labor, and it took a
hundred thousand of them. Probably not true. No, Supposedly, thanks
(41:43):
to h Harvard archaeologist Mark Laner, he conducted a two
thousand to survey and he found evidence to quite the contrary. Yeah.
And then later on in two thousand and ten, um,
just a few years ago, they found tombs of workers discovered, um,
and they basically said, like the way that they were
buried and entombed, like slaves would never have been honored
(42:03):
in this way. There's lots of evidence they were really
well fed. Yeah. They said that um, twenty one cows
and twenty three sheep per day, um was what these
people were eating. So a lot of bread. They found
evidence of, like basically industrial scale bakeries to bake bread
for the workers. Oh huh. And there was evidence of
(42:27):
basically permanent occupation there that said that there were probably
between two thousand and four thousand workers on hand at
any time, but that maybe thirty thousand total over the
like the twenty years constructed the pyramid. Yeah. I saw
the word. They had worked out somewhere between ten and
thirty thousand that worked in three month shifts. Uh. And
they said, you know, while they weren't slaves, they said
(42:49):
it was tough stuff, Like there was evidence of arthritis
and bad backs and all the things inherent in pyramid building. Um.
So it wasn't like, you know, it was easy going.
But it makes sense that you know you, if you
want these things built, you have to have a strong workforce,
which means you have to take care of them and
feed them. You know, ye, pay them, pay the payment
(43:11):
fish pay me. Yeah, that's what they said, ye at
the end of every shift. That's right. So anything else? No, man,
that's Egyptian pyramids. Uh. Yeah. If you want to know
more about pyramids, type that word in a search bar
at how stuff works dot com. And since I said
search bars, time for a listener, Mayo. I'm gonna call
(43:34):
this Australian radio show. I was just talking about us.
Did you see this? No? So that there's a show
apparently the biggest radio show in Sydney called the Kyle
and Jackie oh Show. Did you see this or hear it? No?
I haven't been to I flew through Sydney once for
like ten minutes. I have a chance to listen to
the radio. I mean, did you see the email? No?
(43:56):
I didn't. Okay, that's the second time you made me
admit that. Sorry. Hey guys, I've been listening to you
for years and I adore you both. I also listened
to the Kyle and Jackie Oshow, which is the biggest
radio show in Sydney. That was a good thanks. I
love them too. I have to say that I'm quite
disappointed in them because the female co host, Jackie, found
out about your podcasts and took the piss on the air.
(44:19):
And I think that's Australian for gave us a hard time. Um,
gave us the business, gave us a business, and then
proceeded to share the information you gave in a podcast
if you want to hear it from the June eighth episode. Um,
and it is a podcast as well, about twelve minutes in.
It's actually about nine minutes in, and they talked about
us for about six minutes. What did they say, Well, Um,
(44:42):
here's here's I hope JACKIEO was listening. You seem awesome,
Jackie Oh, because she seems she's sort of made fun
of us, you know that when nds and stuff like that,
and that we just ramble. But she you could tell
she was getting to the show because she even said,
I'm starting to get addicted and she starts reciting facts
from the show. Too late for you, JACKIEO. This Kyle
(45:02):
guy is the equivalent of one of our morning radio
show hosts here in States. Does he have like one
of those bike horns that he squeaks a lot? He
might as well. He's he's like asking about the show,
and she's like, well, you know, like how color works,
and he's like, how cat I wax, Like, what do
you mean? He said, pencil's yella, I want to buy
a yellow pencil? Podcast over Oh yeah. That was like,
(45:23):
clearly this guy's not on our team. Well, I don't
want to he's I don't know, team Chuck. Okay, I
don't want to insult the guy. He insulted us. He
certainly didn't seem to get it that there could be
more to color than as a yellow pencil. That was
a pretty good uh oh man, what was the guy?
(45:45):
What was the band manager from Fly of the concordse name? Mary? Yeah,
doesn't good Murray. I love that show. Kyle equals Murray,
so h Kyle's just doesn't get it. Um he said
it sounded awful. They played a bit of it, oh yeah,
and talked about it a lot. I don't remember licensing
that to them. Well, and at the end she she
basically said, you know what I'll do is keep listening.
(46:05):
And then what they say in forty five minutes I
can just break down for you, guys, and three or
four minutes of bullet points. Okay, I'm pretty sure that
Kyle and Jackie have just started in international flame war
with us. Uh, so to continue the email. Oh yeah,
they clearly don't get it, guys, So let me apologize
on behalf of your other Aussie fans. Uh. You guys
(46:26):
have added so much to the quality of my life,
and I credit you both forgetting me through periods of
intense anxiety where I could not function without having you
both in my head distracting me from my own thoughts.
I can guarantee you Kyle has never been told that. No,
I still adore you now that I'm better, and I
can safely press pause sometimes without even hyperventilating. Thank you
for all you do. Please never stop doing it. And
that is Laura. Thank you Laura. And she said, PS,
(46:49):
I went on a date with a guy last week.
You looked exactly like Chuck, and I have to admit
that is the main reason I agreed to go. Did
he sound like Chuck? Wink wink? Three? X is is
that hugs your kisses? Uh? That is up for debate,
But I say xes or kisses and ohs are hugs Yeah,
(47:10):
asked her how the date went. She was like, well,
I'm not going on a date number two, so it's like,
well they can all be me right. We had a
good ill be chuck. We need a T shirt that
says that they can all. Hats off to you, Jackie O,
because you seem to get it, um clearly, my lady.
Oh wait, Jackie Oh, I thought you were talking about
no Laura. Laura definitely gets it right. Jackie O seems
(47:32):
to get it. She's starting to it. Does not get it.
I don't think Kyle ever will Man and I'm okay
with that me too. Uh. If you want to tell
us about how somebody in your locality is talking smack
