Believe it or not, no aliens were likely involved! Just some very smart humans and a massive amount of labor.
Unrelated, but it would be a very cool project to restore the pyramids to the white gold tipped triangles that they used to be.
it could be kind of disrespectful towards the culture that built them. I dont think we can restore them in such a way it respects the beliefs and culture of those who built them, so best thing to do would be to make sure they dont decay further. Also, restoring them just so tourists can have something to gawk at would be a kin to showing middle finger to those who built and revered them. And i doubt anyone would be interested in doing anything without monetary gain from it.
I’m really curious when and how quickly the route changed.
Did we doubt it was Jewish slaves using levers or did I miss a memo?
It was Egyptian conscripts, according to their records. They didn’t trust slaves with something that important, I guess.
Yeah I don’t think anyone believed that for a while now, that was just what people trying to base their world view on the Bible wanted to be true… exodus didn’t happen either and Egypt doesn’t seem to have had many Jewish slaves.
It was built by aliens but that scares people so they chalk it up to humans to pat themselves on the back
Imagine slaving off your life to build a wonder and there are some people in the future that will say it was the aliens. That’s crazy disrespect.
Hey, at least they got paid.
They wish they did
Imagine coming all the way to a planet light years away and making them awe inspiring monuments just for them to say ‘yeah that’s easy we could do that, in fact we did! We made this!’
Honestly though their fault for using their galaxy age tech to build something about as complex as your average bronze age civ…
Nah, most have been aliens! Those boffins just think they’re so clever.
Scientists may have solved the mystery behind transporting some of the materials to the pyramid site: a dried-up a river
Fixed the title for you.
The construction of the Giza pyramids is still baffling. Some of the stones are purported to weigh 80 tons. That’s four or five times more weight than what modern trucks can pull on paved roads.
It’s not so farfetched to presume that this ancient civilization employed technology that is lost to time. I’m not talking about aliens and laser beams, but good ol’ fashioned mathematics. They could have a exploited a principle of leverage and incline that we simply don’t understand or recognize. Or perhaps something entirely different from our six simple machines…
The problem with this theory, of course, is that we like to believe that humanity is always progressing and that we are superior to our forebears by default. That is ultimately a subjective opinion.
Ah yes, the ancient Egyptian seven simple machines: lever, wheel, pulley, incline, wedge, screw and Agrav engine.
This guy shows how to move large, heavy objects using pivot points and physics.
It sounds silly until you see him single handedly move a barn(!)
That was very cool, thanks for sharing.
I would argue seeing the barn makes it even sillier, but in a good way.
Yeah, I remember this guy. He claimed that Stonehenge in England could have been built like this. The pyramids of Giza are much more complex, of course. Still, I think it’s entirely possible that the pyramids were built using very clever engineering principles that were forgotten and that we don’t need because we have cranes and power tools and hydraulics, etc.

It’s impressive is year 2024, we sent robots to other planets and so many other technological achievements … and still dont know exactly how the the Giza piramids have been done .
We know several ways they could have been done, and could do it ourselves for a sliver of the cost. It’s a matter of historical preservation that we’re not sure which they chose.
The uncertain of this specific case and a few others against other thousand of history remains is what makes wonder
Isn’t this old news? I heard this when Assassin Creed Origins came out and thought it was somewhat historically accurate.
So it’s not just me. Maybe the discovery here was just the exact and complete layout, and the BBC misunderstood the way journalists usually do with science stories?
You’d have a point if the Egyptians didn’t already tell us how they moved giant, heavy things over land.
Lots of human labor.

How many horsepower is that? Also, what is a horse? (bronze age Egypt joke)
Yes. I’m familiar with this image. Some scientists claim that when just the right amount of water is poured over sand it reduces the friction by about 30%.
Some also claim that there were not hundreds of thousands of laborers at the Giza pyramids, based on evidence discovered in the work camps near the site.
I’m 38 years old and I think I’ve read about a new theory every year of my life…
Who are these “some scientists?” Names please.
I’d suggest arguing against what they literally showed us they did is an uphill battle.
Can’t go doing that m8, that’d suggest they might have known what they were talking about, and they talked about a lot of stuff that’s very unpopular these days
“The study was done by Christian Wagner and colleagues at Saarland University in Germany, along with researchers in the Netherlands, Iran and France. The team was inspired by an ancient Egyptian wall painting showing a huge statue being hauled across the sand on a sledge in about 1800 BC. The painting has a detail that has long puzzled Egyptologists: a worker who appears to be pouring water onto the sand in front of the sledge while others appear to be carrying water to replenish his supply.”

There are hundreds of articles about this theory. It was all the rage a few years ago.
I notice you don’t post the names of any of the scientists who believe only a small workforce built the pyramids. Why is that? That’s really the one I was curious about.
Because, again, it’s kind of hard to argue against what they literally carved into a rock.
Again, there are hundreds of articles about the adjacent work camps. Please look at the publications of Zahi Hawass, chief archeologist of Egypt, and Amihai Mazar, a professor of archeology in Jerusalem.
Most claim that there could have been up to ten thousand workers. Some claim that the number of workers was as low as 1600.
I’m not sure why you think 1600 workers mean they couldn’t just drag large stones over land on sledges using a significant number of those 1600 workers. I’m not even sure why you think ten thousand workers would have been necessary. Can you explain please?
You grease up a sled and drag it down a track carved into some rocks.
For the record we do understand how they built it.
They used log rollers, ropes and lots and lots of people hauling. They brute forced it… which, the reason our trucks can’t haul that much has far more to do with the weight on the suspension and fuel efficiency. They said fuck-all to efficiency and literally threw bodies at it.
That said, We do sometimes need much heavier loads
It’s a fairly common solution- the Moai heads on Rapa Nui (easter island) and stone henge also come to mind.
For getting it up the face, they used packed earth ramps that they later removed. Actually, we still use this technique in construction today. (Specifically to get vehicle access up otherwise too-steep slopes)(and again, threw bodies at it. Lots and lots of bodies.)
There’s really only a few things that are impressive about the pyramids. The first is the sheer ego it took to order it built. Then there is the celestial alignment between all of them. And finally the sheer scale of the project and vast amounts of human labor that went into it.
What they determined is that the river allowed the blocks to be floated much closer than previously thought (even today barges are superior to trains, never mind trucking.)
They said fuck-all to efficiency and literally threw bodies at it.
Well, given that they didn’t have trucks, that’s a little unfair. Animals or people with ropes was the most efficient solution.
You’re right, I s’pose.
But it gets back to… was it really worth doing? It’s a monument to a single man’s ego.
Well, what else are you supposed to do when you’re overlord of the only empire in the known world? Something for the peasants? /s
Yeah, sorry, that was just a nitpick. All the rest I agree with.
I swear that I’m not trying to be obtuse, but I have a lot of doubts.
What kind of ropes and wooden sleds, manufactured in 4000 BC, can move 80 ton stones? There are tensile limits…
So, each rope only needs to be too strong for the individual worker to snap. Obviously, that’s pretty easy, even with the worst natural fiber cordage - fibers are strong. Then they meet in some way, and ultimately attach to the wooden sled. The exact math for that is not straightforward, and we don’t really know how they tied it off, but it’s not an unusual amount of load for a large wooden structure. Assuming the sled measured 100 meters2 (80 tons was a special block worthy of an oversize sled), that works out to less than a ton per square meter, and a tree with 1m2 cross section at the trunk can weigh several tons without even considering the wind load on the foliage, which will be larger yet for most species.
80 tons is a lot, but it’s not a lot a lot. Thousands of tons are pretty common if you’re talking about ships, for example. Even the wooden ones; honestly wood is an underrated material.
Yeah people really forget how recent an invention good rope is, It’s not like they could just order a few hundred meters on ebay. Making all that rope would probably be more effort and expense than a lot of the stuff that people write of as too complex for them to have considered, like temporary canals or raise and drop sledding.
Rope braiding is pretty fast. Especially if you’re an ancient Egyptian woman who’s done it full time for decades. They had hemp, which is the same stuff that rigged up the giant sailing ships of later on in history.

There’s a new theory that the ramps were actually internal. I like it because it means they don’t need to bring a lot of extra material and manpower to the site just for the ramps since they’re built into the structure of the same material.
I’ve also heard of this. It seems to me that this theory should be easy to confirm with some sort x-ray or radar or lidar or something, so that we can see the shape of the structure beneath the superficial layers…
I didn’t think it was so much a question of how it was done vs how it was done so fast. Iirc, 20 years to build the Great Pyramid?
