[@BirdYoumans]

I'm sure some of you much smarter than me can blow holes in this, but we still use string today to level and square things. I'm thinking a string up the side of the pyramid once the angle was established by the first two courses of stone could have gone a long way to keeping the sides at a constant level. Once you lay out the 1st course, you put course 2 in place and by adjusting how close that course is to the outside of course 1 will determine the angle of the side of the pyramid. 2 stone closer to the edge, steeper angle. Farther from the edge, not as steep. Mix to taste, but then once that is established, attach the string to the upper outer edge of the first course and bring it up to where it just touches the upper outer edge of course 2. Put course 3 roughly in place and pull the string up so that it barely touches course 2 and then make the final adjustment of the course 3 stone. As long as each course touches the string, the side will be the angle created by the first two stones.

[@mmneander1316]

Good point. As a technician, I have to note that the distance between the reference points significantly affects accuracy. I think line of sight is the key. If you can sight along two points A and B 100m distant, then finding a point on the line 1m distant from point A is very accurate. So my theory would be: They would have built wooden scaffolds, of maybe 10m tall, to hold points to sight against (surely a trivial task given the magnitude of the whole pyramid project). Once you have built 10m of the height of the pyramid, you can use the sides of the pyramid to sight against. The higher the pyramid gets, the longer the sighting distance gets, and the more accurate the extrapolation of the line to the higher levels.

@@StefanMilo I'm watching the playlist as I type this, it's really good so far. Wanted to ask you, are you familiar with the tomb of the "Griffin Warrior of Pylos"? I can stare at the Pylos agate found in his tomb for hours on end, imo it's the single most beautiful work of art from the BA. It hasn't gotten the attention it deserves. It rivals any great work of any age. I'm an ancient coin expert, I would go as far as saying that the greatest engravers of 5th cent bc in Sicily could not compete with the person that engraved the agate, it's that good. And the Sicilian engravers were the best the world has ever seen. Keep up the great work!

@@StefanMilo The Egyptians eventually did have coins, but it came under Ptolemaic rule, but I don't think that's what you meant lol. I deal in Greek, Roman and Judaean coins, with Roman Imperial coinage being my primary area of focus. I've definitely noticed that you cover those wonderful niche areas of history that I so love, and that was partly my motivation for telling you about the Griffin Warriors tomb. It's a recent find which really shook the foundation of our perception of BA art. I think that the only comparable piece is the Minoan god boy statue, I don't recall what he's called. I'm curious, do you have a favorite dynasty? It's really easy to love the 18th. And Ramses III is highly underrated imho.

[@SandyRiverBlue]

Great choice of background! Some folks say that the blocks in the pyramids were so heavy (about 2.5 tons apiece) that we no longer have the technology to stack them in large numbers. And yet I spent a whole summer as part of a small crew of 8 people, doing the impossible; placing thousands of 4,000-5,000 lbs (about 2-2.5 ton) gravity blocks on retaining walls that stretched along several US freeway extensions. And we weren't the only crew, there were others in metropolitan area and I'm sure there were others throughout the state and throughout the country. Just in tonnage, based on some basic multiplication and DOT filings, we placed more of these puzzle-piece retaining blocks in the last 23 years than Egypt did in it's entire history.

[@haroldbarr8511]

I watched a documentary where an architect came up with a more likely way of building the great pyramid. His computer design lead to the idea that there is a spiraling tunnel on the inside of the pyramid similar to a multi story parking garage. I feel like that is the most likely way it was built. From the inside out, after the first 20 meters using a ramp.

I heard a theory that the granite was cut with sandsaws: basically saw handles with no blade, under which they'd just pour sand. They'd rub the sandsaw back and forth, using the sand itself to cut stone. Apparently it works, and you're never going to run out of sand, because as you work, you get more and more granite sand. As for what the postholes do... I dunno, to me it seems obvious that people would wrap ropes around these posts and use them as pulleys.

But sure, aliens.

[@maxanom6234]

@Oftin Wong okay then mate the Egyptians very clearly cut granite with sand and saw handles, you clearly provided such good evidence. Because "sand is quartz" oh wait no its not sand is made of multiple materials. And because "sand is harder than quartz" oh wait no it's not they are the same have a little look on Google since it seems you like it so much. And because "there is plenty examples" oh wait no there isnt you showed me one example and yes the sand does cut it, but it cuts it at an extremely slow rate making it a completely useless way to cut anything so obviously wasnt used to create blocks for the pyramids. So I think maybe you are stuck in your head a little instead of looking at the facts here.

Like a ratchet, the log prevents the stone from retreating, and can be moved up the ramp in pairs using the post holes to hold them or anchor them somehow?

[@rojopantalones9791]

When it comes to maintaining the angle, my guess is that they simply calculated the number of stones for the length and width of the base, and then reduced that number by a fixed ratio to get to the number at the top. It's like if you are setting up bowling pins, you know you've got 10 pins and want a single one at the front. That leaves 9 pins, and you want it to be wider at the base. Well, 4+3+2 makes 9, so you align them in a triangle of 4 at the base, 3 for the next layer, 2 for the next, and 1 for the apex. Except you're doing that in a three dimensional space, which makes it sound complicated, but you'd only have to figure out a single side and can still treat it like a two dimensional plane, cutting a cross section through the widest point, cutting that in half bilaterally, and then doing a little trig. The first records of the study of triangles goes as far back as the 2nd millennium BC in Egypt, so, in the grand scheme of things, possibly contemporary with the building of the pyramids. You don't necessarily have to get into super complex mathematics in order to calculate the number of stones needed to create the length and height of that right triangle, as you can do it by hand, much like writing out 5x4x3x2 instead of 5!. It would take a while, but, with nothing but a writing implement and a straight edge, you could draw up that triangle, draw out the divisions to indicate the stones, and physically count them. Much math is just shorthand for observations of reality, a way to conceptualize it and break it down into something that others will understand. You could calculate out the proper amount of pressure you need to apply to your gas pedal in order to accelerate your car to highway speeds while merging in front of a car coming from a certain distance away, but you just feel it. That mathematical shorthand, especially if you understand it well, will easily beat out someone trying to physically count each stone they're going to need when it comes to time, but you're still likely to reach the same conclusion. I'm sure they went in with an idea of how tall and how wide they were going to be, and the angle of that might just be a byproduct. Maybe the width and height bear some sort of significance when it comes to their amounts in cubits and spans or whatever unit of measurement they happened to use at the time? Like you said, more information is needed to know for sure how and why.

Great video After studying this very topic for the best part of my 74 years, I myself have come to some controversial conclusions: That they had iron tools. What percentage of their tools were iron, bronze or copper I'm not sure, but for the granite I suspect iron. A video from Ancient Architects shows the location of an iron ore mine on the Gizeh plateau which probably dates from the 4th dynasty. Secondly, I suspect that the Great Pyramid was built in stages, corresponding to the 3 "tombs", and that the building was finally completed by Kufu....and that Kufu did at least build the upper chamber, grand gallery and "relieving chambers" I think is now beyond dispute...but the "Queen's chamber" and the "cellar" ?? What really fascinates me is whether the whole complex was a single design - which I think it was - or whether they pyramids were build one after the other - I suspect they were all built at the same time as some sort of pattern and I think Bauval is right about this... As for the Sphinx.......

An iron mine alone is not sufficient as evidence for iron tools, it is the temperature at which iron becomes malleable that is difficult to achieve

I read that the dolerite balls were actually not round when they were working with them and had hard edges. They became round as they were used and the round balls were then used for another task. Given that you would need round balls in the later phases of construction it makes sense they would be found at the end of construction. I found this info from an academic source that was explaining the giant obelisk with the so-called "scoop marks" and the video was explaining the process of burning super hot fires and then banging out those scoop marks by hand with the dolerite balls with the harder sharp edges not the round ball style tool. I would love to see a video about this subject because every alternative history channel covers this huge obelisk and it is easily explainable using techniques we know the Egyptians used.

I've watched my father cut sharpening stones out of boulders collected from the river before. He scores a line on the top and sides of the block then puts a long dull sword looking piece of metal to the top line and hits it a few times really hard and the block of stone breaks straight a part following the lines. If you chalk a line across the center topside of the blocks, it makes it easy for novice laborers to align the next block and the next layers of blocks.

I get why ancient aliens conspiracies are appealing to so many folks. 1) it plays on the underlying belief (desire?) that a lot of people have that we are smarter/more-special than ancient 'ignorants', so it's impossible for them to have thought as cleverly as we do & been crafty enough to accomplish things that we still find impressive; 2) it helps reinforce some eurocentric (read: bigoted) beliefs that would prefer it if the presence of advanced native-african (or new world) civilizations like we have so much evidence for along the Nile & the east coast of the continent could be discredited by attributing all of their accomplishments up to extraterrestrials; now that it's become harder to pretend that it was secret white people like the Hamitic "hypothesis". 3) like all conspiracy theories it simplifies things so that rather than facing the reality that life on earth is the result of billions of independent wills pulling our species in all directions at all times, you can just blame everything on the lizard people secretly controlling everything; 4) it's more fun than a long slog with a lot of blood, sweet & tears; even if others of us enjoy finding out that the ancient builders of the pyramids who toiled away to achieve these amazing constructs, received part of their salary in beer 5) as more & more of us become convinced that intelligent must exist somewhere else in the universe...which in turn means that there's a good chance that it is wide-spread throughout the universe; given how far from the center & oldest portions of the universe our galaxy sits...we want to think that we are special enough for them to have visited us; which leads either to ancient aliens -- be they pyramid builders/atlanteans or the cause of conscious thought -- or to Area 51 & modern lizard people. 6) if life on earth was sparked by meteors bringing some of the building blocks of life to the planet, then we are in a way the result of ancient aliens even without intelligent life from other planets having played a part in our history. So on a very metaphorical level there's a ring of truth to the idea, one that is simply taken too a literal extreme because of the previous factors.

I think “aliens” are used by mainstream academics to disregard any other theories but no one is saying aliens. Some people just don’t think that copper tools were able to make these enormous monolithic stones and then dragged these stones to the sites miles out. Some of these stones are 10-30 tons which means a ramp like the ones used in mainstream theories aren’t liable.

4:50 If they did use copper saws (definitely IMHO), they wouldn't necessarily lose the copper blades. Just take the fallen sand from the cutting technique, and heat it.

If you have two sticks in a 90 degree angle and you have a third stick attached in the required angle of building. You can place this triangle on the base with the bottom crossing at the edge of the stone. The next row of stones should be placed against the straight up stick and the height of the stone should be at the top crossing of the triangle. Now you have the required angle between the base stones and the next row. If you follow this rule every next row of stones you will get a consistent angle all the way to the top of the pyramid.

My theory: I think, in reality, the ancient Egyptians would have been able to build the pyramids a lot faster, with a lot less men than what these estimates assume. This is because I understand, in science, more conservative estimates are generally preferred, and Stefan clearly said these estimates are based on what the average modern man is capable of. Which means these estimates are ignoring the fact that these were farmboys - ancient farmboys, with primitive tools. These boys worked unimaginably hard all day, almost every day of their lives. You ever try to arm wrestle a farmboy? I consider myself slightly above average in strength by city-boy standards, if I can't win an arm wrestle I can usually at least give a decent fight. But with these farmboys there's no way, they slammed my arm down immediately with no effort, every single one of them. I feel like a team of ancient Egyptian farmboys could haul more stone, faster, and with less men than what your average modern men are capable of.

I might suggest that the apparent dips in the middle of each side, which you don't directly address in this video, could be the artifact of the way they maintained the perfect angle along each edge to the top.

Here are my theories on the 2 last questions. 1; The People used the ramp and worked off that. The final parts were probably just the workers moving the Stones used for the ramp up to fill out the remaining part. 2; The angle was kept by ground people looking at the pyramid with big sticks or similar instrument to measure if it was complete. Or they were the beta version of Pytagoras.

[@jakub.h4546]

Very interesting insight indeed. However, I still incline to the other theories. As you mentioned at the end of the video.. HOW on earth did they stack those massive stone blocks on top of each other? Why were the pyramids build atop of a water reservoir? What is the purpose of the inner shaft / tunnel system? WHY aren´t there any hieroglyphs in the pyramids? WHY wasn´t there any mummy discovery inside the pyraminds (literally. there was no mummy found in a pyramid, ever.)? How did they manage to build the Great pyramid in the center of the earths landmass? And why aren´t the pyraminds EVER mentioned in the hieroglyphs?? It´s all confusing. Dang!

[@TheGreatPyramid]

Built atop a water reservoir because they used an inner well to lift water to each succeeding level of rise... thus answering how they kept it square at the top as the video-maker rightly wonders about... this is a little known fact I will be revealing with diagrams, etc. down the road a bit on my channel....

[@nakenmil]

1. How did they stack those massive stone blocks on top of each other? The video provides an answer for the lower levels, and a possible explanation for higher levels. It would've been hard work, and probably require a great deal of practical know-how and some geometric understanding - but we know that the Egyptians had all that, and the pyramids do exist, so clearly they made it work. 2. Why were the pyramids built atop of a water reservoir? Do you have a source on the water reservoir? I tried googling it, but I just found mentions by conspiracy theorists. 3. What is the purpose of the inner shaft/tunnel system Something related to the construction or inspection? Doesn't strike me as particularly mysterious. 4. Why are there no hieroglyphs in the Great Pyramid? Well, why are there no emojis on gravestones? The answer is likely that trends in decoration changed over time. For a long time, it's quite possible that they preferred more austere, minimalistic decoration of the grave chambers. For example, the first stepped pyramid, that of Pharaoh Djoser, contains hieroglyphic inscriptions in the grave room, and it also has a ton of caskets and boxes which were inscribed with the names of previous rulers. Then there is a long gap with no hieroglyphic decorations inside the grave chambers, but by the Fifth Dynasty, these decorations return, in the Pyramid of Pharaoh Unas. EDIT: Turns out there were some hierglyphics left inside the Great Pyramid. They weren't decorations, though, but probably left by builders for practical purposes during construction: www.nbcnews.com/id/43314221/ns/technology_and_science-science/t/mystery-pyramid-hieroglyphs-it-all-adds/#.XH6eaYhKhPY Here are hieroglyphics from the grave chamber of Pharaoh Tetit, who was the son-in-law of Pharaoh Unas: upload.wikimedia.org/wikipedia/commons/f/f7/T%C3%A9ti-textes.jpg 5. Why has there never been discovered a mummy inside the pyramids? Well, first off, there actually has been recovered human remains inside a pyramid: they found parts of Pharaoh Djoser's mummified foot inside his still-present sarcophagus in his stepped pyramid. However, secondly, the more clear answer is: grave robbing. Pyramids REALLY stand out against everything else, they are giant monuments rumored to have treasures in them. So they got robbed. And there were several thousand years to rob them. We do have mastabas though (mastabas were grave-mounds that the Egyptians used before they began making pyramids) where we have found full remains of mummies and bodies inside them. Mastabas have the benefit that they are less conspicuous against the horizon. Inside them we also find such things as sarcophagi (which we also find in pyramids, albeit usually empty and looted), and grave goods. We also find these in the later style of tombs, the cavern tombs in the Valley of Kings and such. There has also been discovered a full sarcophagus in the pyramid of Pharaoh Menkare, which is also located at Giza. So we know there used to be bodies in there - but as I said, they were looted. 6. How did they manage to build the pyramid in the center of Earth's landmass? Where the centre of Earth's landmass is depends on what you regard as the outer limits. People have have gotten results such as lower Egypt, Turkish Anatolia, and even Romania: gis.stackexchange.com/questions/83022/calculating-centroid-of-all-lands-of-earth-using-sql-server-spatial In the end, it's a pointless issue, but a "center of Earth's landmass" does not have any specific significance, nor would the Egyptians have known about the Americas, Antarctica or Australia in order to find one. The answer is mostly that the Egyptians built their pyramids next to the Nile. Because that's where they lived. 7. Why aren't the pyramids ever mentioned in the hieroglyphs? Did you miss the papyrus in the video that explicitly talked about Khufu's pyramid? Here's more on it: www.history.com/news/egypts-oldest-papyri-detail-great-pyramid-construction Here are the Pyramid Texts, a series of holy prayers which were written on the pyramids at Sakkara, which date from the 5th and 6th Dynasties (around 2500 BC).

Coming from a building background, I’m still unsure how it was possible to lay that many blocks per day, for 20 years straight. It basically works out to be 13.1 blocks per hour were laid, over the course of the 20 years. If on average the block were 2.5 tonne, and you could somehow get 10 workers to each get both hands on the block, they are still lifting and moving 250kg each. You try and lift and move a 250kg block up into place. You can’t, we just don’t have that strength. Even if they were using lifting methods, it would take hours to position just 1 single block into place and get it right. You speak how it’s still unknown how they levelled the site, but they would constantly need to be re checking the level as they built up. They would have so many errors and would need to take blocks off and re position them to get it right. I’d say every 2m in height, they’d need it to be fairly bang on level, else it would be so far out of shape by the time it got to 10m high.l, let alone 150m. I like all the facts you rattle off, but it’s insanity. 13 blocks per hour, up a ramp, with hundreds of workers trying to pick up a 2.5 tonne block and place it, get out of the way of the next block. That’s 1 block every 5mins. Add in mistakes, errors, accidents etc etc. there is simply no way. Go to a building site today and see how long things take to be built. Even with lots of man power. Even with the latest technology and machinery.

Maybe the post holes were to put some wood or ropes across the ramp at the end of the work day so that you don’t have to have all the blocks up the ramp at one time? It keeps the process constantly flowing. Also can’t you just start flipping blocks one on top of the other? So you don’t have to ramp them up at the top. But push them on top of one another?

Perhaps.....from outside of ramp, you drag one end of rope up, up, up and around pole. Then down all the way to the stone. Wrap around stone, to other side of stone, and then up, up, up to pole on other side (directly across from other pole). Wrap around that pole, and back down all the way. Now using all that manpower pulling both ropes, will gradually slide stone up the ramp. Lock in place, at a point (like you suggest) reposition ropes upward on next poles, and repeat. Meh, just a thought.

If you have a shaft of a diameter large enough to contain ONE block and it’s float, the weight of the water column would create a very substantial pressure at the bottom. Consider the way it has to be harnessed and how the gates have to be operated against that pressure. I often travel on canals, and the locks they have there are difficult enough with a head pressure of 4 meters. And to name another thing.
