    The constant barrage of Joe Rogan clips of idiots claming it was impossible to move these huge stones over those distances with the tech at the time was what drove me to disable YouTube shorts.

    Lifting it is like 1/100th of the challenge. Moving it across hundreds of miles, cutting it, getting it to the top of the pyramid, and setting it in place are all bigger problems than simply lifting the stone.

      Nobody has so far given you a serious answer, so:

      Cutting - They only had IIRC bronze, which is not enough on its own to cut through the granite. However using sand to add friction makes it cut significant faster/easier.

      Moving miles - Boats are incredibly capable of carrying heavy loads with minimal energy expenditure to move said boat. Using logs and levers also goes far.

      Getting to the too of the pyramid, that’s a little more of a mystery. But there is evidence they included ramps within the structure as they built the bigger ones as they went. And IIRC the smaller ones had pulley systems going through the center.

      It doesn’t require fancy tech, just of patience and application of basic physics.

      Here is a guy using some of the basic movement techniques in his backyard with multi ton stones:

      Lifting is the hard part, you can move blocks short distances on rollers, long distances on barges, really short distances by a dozen men pushing

      If you take the heaviest stone and divide it by a reasonable weight to walk long distances- say 20lbs, you find you need a few thousand people to carry one stone. You need several thousand ropes for each worker, but again each rope only needs to lift 20 lbs of the whole.

      Modern estimates put the number of workers at 10,000. So they just had to carry them.

      It’s no wonder they didn’t document it. Lift stone and walk. What’s the big deal?

      Slavery: It get shits done.

      Moving material gets done via cart, or rolling on top of logs. I had heard various theories for how they got the big bricks up, from rolling up a dirt pile (put into place by, you guessed it.) to building a waterproof chute with the bricks in it on a raft, and just filling the chute with water to make the raft go up.

    A couple years ago my chemistry teacher told my class that the Egyptians had really advanced technology (technology even more advanced than our own) thousands of years ago but it all got lost because they started a nuclear war

      Pfff I’m sorry but no, it was the cats.

      You see cats have powers similar to Telekinesis. Why do you think they choose rivers surrounded by deserts to start the first civilizations. Sandboxes everywhere they please.

      But one dark day the Faraó Ramses forgot to refil the food pile because and I quote “but it still had food from yesterday”.

      This one mistake doomed humanity to the eternal silence treatment.

          The Greek historian Herodotus instead depicts Khufu as a heretic and cruel tyrant. In his literary work Historiae, Book II, chapter 124–126, he writes: "As long as Rhámpsinîtos was king, as they told me, there was nothing but orderly rule in Egypt, and the land prospered greatly. But after him Khéops became king over them and brought them to every kind of suffering: He closed all the temples; after this he kept the priests from sacrificing there and then he forced all the Egyptians to work for him. So some were ordered to draw stones from the stone quarries in the Arabian mountains to the Nile, and others he forced to receive the stones after they had been carried over the river in boats, and to draw them to those called the Libyan mountains. And they worked by 100,000 men at a time, for each three months continually. Of this oppression there passed ten years while the causeway was made by which they drew the stones, which causeway they built, and it is a work not much less, as it appears to me, than the pyramid. For the length of it is 5 furlongs and the breadth 10 fathoms and the height, where it is highest, 8 fathoms, and it is made of polished stone and has figures carved upon it. For this, they said, 10 years were spent, and for the underground chambers on the hill upon which the pyramids stand, which he caused to be made as sepulchral chambers for himself in an island, having conducted thither a channel from the Nile.

          https://en.wikipedia.org/wiki/Khufu

          Among the items recently found were hundreds of fragments of papyri. Some of these were inked with records that were the logbooks of a group of some 40 workers who were crew on a boat during the reign of Pharaoh Khufu. They record the transport of limestone blocks along the Nile River and then through a series of water-filled basins, using terms such as “Khufu’s Lake”. At the base of the pyramids, workers unloaded the rock to cover the outer layer of the Great Pyramid, then, the boat crew would head back to a quarry for another load of rock.

          I am not sure they found any boats other than the funerary ones, but they seem pretty comparable.

            This is very interesting but he is asking about pulley systems. A block and tackle is a pulley system that gives a mechanical advantage in lifting something.

    The great pyramid of Giza weighs around 6 million tons https://weightofstuff.com/how-much-does-the-pyramid-of-giza-weigh/

    An average human can apparently develop about 200N https://www.ccohs.ca/oshanswers/ergonomics/push1.html

    Meaning that an average human would need a lever about 3×10^8 m long (considering a 1 metre load arm) to move the pyramid.

    Do you find this credible?

    ETA: some people think I’m serious. This is quite the flabbergast.

      I’m going to go out on a limb and say i don’t think they found the pyramid whole and moved the entire thing. I think they took small pieces, possibly block shaped and moved those one at a time

      Don’t worry I got what you were putting down. People can be very reactionary with their downvotes here, if your joke is too subtle it can fly over their heads.

      It made me smirk! For my reference, how many zeros is that (I’m shit at maths but want to try and imagine such a long lever protruding into deep space)?

      The ancient Egyptians utilized neither wheels nor work animals for the majority of the pyramid-building era, so the giant blocks, weighing 2.5 tons on average, had to be moved through human muscle power alone. But until recently, nobody really knew how. The answer, it seems, is simply water. Evidence suggests that the blocks were first levered onto wooden sleds and then hauled up ramps made of sand. However, dry sand piles up in front of a moving sled, increasing friction until the sled is nearly impossible to pull. Wet sand reduces friction dramatically beneath the sled runners, eliminating the sand piles and making it possible for a team of people to move massive objects.

      You’re gonna need a bigger load arm. The pyramid is way more than a meter across.

    Me, looking at the meme: I wonder what happened to that giant pole they put on top of the pyramid to lift the giant weight?
