i respect the guy, especially for speaking in a language thats not his native, great that he followed his childhood dream
The answers are in my post on IG:ds7v7n
Oh my god go to brunch Karen
@@joshjoshjoshjoshjoshjoshjoshj 😂😂😂
@Fresh Sodaa I respect his native language as well, but it’s even harder to speak in a language that he didn’t grow up with
He already has a good command of English. Its just that he has a thick accent. Notice his vocabulary and use of technical terminology. Non native English speakers do this all the time. It's just that some of us have thicker accent than others.
The main thing I learnt from this is he is an extremely slow climber.
so how long will it take>?
@@ashansenarathne7703 the two young ppl that climbed it in a half an hour spent the night n got busy up there ...w/pics....
A truly fascinating exposé to potentially rewriting GIZA archeology and redefining construction methods.
Good show!
This technique has been around for a decade called Photogrammetry. I personally used it in a project in 2006. Today the tech is much better because we can now create finer detailed point cloud data to get structures. It’s commonly used in Hollywood visual effects for 3D set extensions and compositing.
I want the 7 minutes back.
That's really cool, hopefully you can continue your reasarch and give us a sound hypothesis on the construction methods.
Sort of shows that the interior stones are rough cut and rough fit blocks with a fair amount of fill. The exterior stones are more refined blocks with very little fill. It would not surprise me if the amount of permissible fill decreases as you go towards the base since the load is much greater.
The top section does offer a clue! It shows a twisted or spiral core. This could mean a spiral internal ramp!
2:22 Can't believe the internal ramp theory of Jean-Pierre Houdin still isn't accepted as the most likely method.
AndyPutt1 there was thermal imaging that shows a shadowed are that seems to confirm that the internal area has a hollowed area that is a ramp going around the perimeter
Because to use a ramp to drag one of those blocks to the top would require a ramp one mile long and would contain a lot more material then the pyramid is built of! This is why the theory is dismissed!
@@philwhatever3903 Jean-pierres theory is an internal spiraling ramp. Not the one you are refering to.
I thought Houdin's theory had to be right when I first encountered it as it seemed to deal with so many factors.... But I gather latest 'scans' show no internal passageways, and his American backer has accepted that Houdins theory is incorrect
I’m still fascinated by Houdin’s theory, but there are simpler approaches, like Müller-Römer for example. I don’t really understand why nobody talks about it..maybe because there was no huge PR campaign around it.
I dont think he was intending to show new things but rather to show technology we can use to evidence some of the various theories.
This was pretty good. Fascinating concept to look at the core of the pyramid.
The pramids i think was built from inside out. All the chambers, walkways, galleries and rooms were built first with those large limestone & granite blocks stones revealing a type of tower or church type tall construction. Then all around the construction was filled with sand rocks and rubble till getting to measured ground they mapped out then the limestone blocks were laid using a step up tier system in the middle of all flat sides of the pyramid
He took 7 minutes to say nothing.
exactly ,, 3d image and 3 probable techniques ,,, only thing I grasped from 7 min.
Bryon Lape soo true
He will reveal the reality of pyramids
Not nothing, he spent that time explaining how he and his team shot video of the pyramids. Few hundred years ago such feat would have been unmanageable :)
Bryon Lape pretty much
Well done, very interesting, thanks 🙏
They could scanned the whole pyramid with drone, and not even left the ground.
Drones are highly restricted throughout Egypt. I don't think he was looking for a flyby of the Egyptian Air Force!
Very good point, use of a drone could have been used for a great scan of the whole pyramid.
@@fredericrike5974 why restricted?
@@ashansenarathne7703 Much of the actions of the Egyptian Government, as expressed by the Cairo Museum, have been about "controlling the narrative" both of Egypt today and how it's ancient history are seen. An "unauthorized" and uncensored drone photography could well have got espionage charges from the current military government. Or even many of the "civilian" elected governments. FR
@@fredericrike5974 Thank you FR for comprehensive explanation. Now clear.
for everyone saying “that explained nothing” the title of the video never claimed that it would be explained in full, just offers clues

I learned ignorance and racism just reading your comment.
thank you nat geo for this information we hope they can achieve their goals
dat boi to know how the pyramid built
dat boi ok
reading about this for essay, helped thanks
I really like the inner staircase theory. Question...has anyone here ever carried a 150Lbs sofa up a flight of steps? Not easy right? Now imagine doing that with a 4 ton block of stone...hell, even a 500 or 750LBS block of stone.
Everybody has a theory. I want to see that theory applied. Nobody does that. Why? Everybody is wrong. The builders clearly knew something we don't. Slave labor? Really? Go buy a desk at IKEA then try to assemble it without directions. Now imagine an undertaking as massive as the great Pyramid. I want to see an Egyptian record of training and education for Pyramid builders. You guys wanna come over and hang out in a skyscraper me and my buds put together? We only missed a few rivets and hell, there were only 250 bolts left over. I am sure we will all be just fine. Every hand in this design from quarry to placement were highly skilled. I doubt we will ever know what really transpired during their construction.
I think they worked out what was coming and built it for survivors!
GeezerGamerz I totally agree with you... I wish the world would stop and collectively ponder how these pyramids could have possibly been assembled. Once we all came to a couple plausible conclusions I think either way you leaned it would drastically change the world forever. The pyramids are a microcosm for the citizens of the world excluding the "elites"... we don't know shit and will spin in circles until we die without possibly ever knowing the real truth about how WE were constructed.
GeezerGamerz some form of kinesics was used, whether telekinesis or a combination of electro-manipulation of local gravitational forces in counterbalance for lift cannot yet be tested. But, very soon our technology will help us discover their (the ancients) technology. At that moment global construction advances and economics expansion will improve and develop exponentially to its apex, wherein humans will attempt a “World’s Largest Structure.”
There are a lot of theories my favorite is concrete where the outer stones where built close to the site but most of the interior where it wasn't necessary was a poured and mixed concrete but I've also seen other videos where people have climbed the pyramid and there is exposed brick and mortar I don't think it would be impractical to carry the 100s of thousand maybe even a few million several ton blocks to the top so if they knew how to make concrete why not you could transport all the necessary ingredients in baskets up to the top and only have to carry a few stones here and there and also if you look at a diagram where they measured the average size of the stones on the outside the gradually get smaller but it is very interesting since they didn't have the tools that we would think of also someone did a study when they found a glass artifact to see if you could harness the sun to cut the stone and it kinda worked they by no means got it down but it kinda proved it could be done I guess almost anything is really possible
Save yourself from trying to convert these "ramp theorists" over a youtube comment. It took this guy 5 hours to climb it, 5 hours just to climb it hello? Imagine moving a few ton blick on the top and then maneuver with it, align it to the N,S,E,W and by how many people? These are just 2 facts out of thousands more that these "professionals" seem to have a blind eye for.
Still no clue, even the most intellegent people of today come up with their theories, still no clue how these were built, stumped, love it.
The only way to find out, is actually trying to build a pyramid today with the resources the Egyptians had at that time.
Just to discover that it wasn't possible? All accademics would oppose to that prospect. But I would gladly see that. I would even gladly see one 30-ton block quarried with bronze chisels, transported from the quarry, carved, elevated to a hight of 50 meters and placed perfectly on top of other blocks. Just that.
I'd like to see a hypothesis of how they leveled the ground for the pyramid of Khafre. That is, how they quarried enormous blocks of bedrock (measured in yards, not just feet) and moved them from the "high" side of the site to the "low" side of the site.
@@nazmor661 I respectfully point out that is a belief. If it's all miracles then no analysis is necessary. If the claim is that there were people who used methods then there must be better proof.
oh I love this approach. I hope the mainstream will use this method from hence forth!
Maybe you should have taken drone with...one with a hi-res camera??
I learned absolutely nothing
Lmao
I agree, nice lecture, but I learned nothing
He literally told us nothing. Showed us a 3d rendering of the top of the pyramid, didn't tell us how they built it.
I’m glad it wasn’t just me!
8 minutes to say ... i still don´t know how they did it
i like the theory that the larger pyramids were filled with wasted stone scraps, sand and other fill materials. helps explain a LOT of problems, like impossible const. time line, stacking, setting into place. outer layer(s) only of blocks.
Wonderful presentation, perfect, emotional and inspiring, enjoyment for the eyes and ears. Sincere congratulations.Yukinori we want more !!
美しいプレゼンテーション、完璧で、感情的で刺激的な、目と耳の喜び。 心からおめでとうございます 河江ゆきのり、もっと欲しい!!
Maybe his team should have included an architect and an engineer.
If there were no subtitles I would've been lost
Lmao
Fr I understand everything without the subtitles
What a cool archaeologist !
offers clues to how pyramids were built - except it doesnt.
Well we now know the craftsmanship was pretty bad. The blocks were somewhat random cut and uneven in height. And there large voids inside so that they were only concerned about the exterior look, and could skimp on material.
Armand L 'nikitich'
How do you know this?
Gary Wheeler
Isn't that just the facade? Aren't the interior blocks cut so precisely that a sheet of paper won't fit? The alignment so perfectly oriented NEWS?
Peace.
@@dexterd1188 The interior looks pretty crude. Some f the bottoms uf blocks are kinda crudely zee shaped to fit a low block on the left while one on right is higher. It looks like you can stick your hand in some places. Maybe they got sloppy at the top though.
Gary Wheeler don’t forget the structure has been standing for thousands of years... and the land has gone through incredible violence and raiding. Many of Egyptian structures and artifacts have been desecrated and often materials pulled from one structure to build another.. I mean Jesus Christ even the mummy’s were taken and bodies ground into powder to create some sort of medicine or drug back in the Victorian era...
I watched it without sound and understood it quite well!
is there a way to purchase the pointcloud???
im reconstructing the missing casingstones and i need submillimeter accuracy.
Yes. The biggest problem on how to figure out how the pyramids were built is.. nobody really knows what the inside blocks look like. The usual guess is they are uniform and stacked. But that might not be so.
Thank you I have questions how they build the 5 plit is 17th
Astonishing.
Who would ever think that computer technology would have these ideas awesome
we can see how the internal construction of the entrance, passageways & chambers were built but we do not understand how the outer stones were laid
Ramps are fill up and must be compacted. In lack of suitable frame constructions (supporting of the flanks) and compactor plates it's unlikely. Proctor density must be guaranteed. otherwise all bulk starts moving away downwards.

Enfin au milieu des théories ésotériques et/ou poétiques, une information factuelle, rare, sur la réalité de l'empilage des pierres dans une petite partie de la pyramide !
I would like to see a full animation how they did. I saw some but not really satisfying. It puzzles me all the time.
Oooohway Cool!!
My view I think the Pyramid construction was built starting with laying the first level of floor and then building a outer ramp up at each completed stones height on only one narrow area of the face of the construction. Build up ramp after each completed level up until you get to the height of the Grand Gallery then the Grand Gallery was used as a Counterweight lifting area to lift up the granite stones used to build the Kings Chamber via a drop down the Grand Gallery of a huge block across track and rollers and ropes to pull up the granite stones at the opposite side of the Pyramid. Then the upper half of construction was built using an elevator drop & lift of stones
Well ur think of view is a dump... Its spiral dude... It was discovered 10 years ago..
Do the people in the audience get subtitles?
Learn some English and you'll understand.
Not watching video after reading comments.. thanks you commentators for saving 5 minutes of my life.
Yeah, except it took 6 minutes to read the comments.
I got more information from my Lara Croft game than this presentation.
The day Aton returns is the day he will explain how he has built it and why.
Interesting
I love the topic but I can't understand. Though there is a subtitle his voice keeps blowing my ears
For a National Geographic presentation, you'd thought they'd know how to use drop shadow on the subtitles or at least put a plain bar behind the text.
I have just paused it and am looking at both things you describe.
7:23 He almost bow at the end but then he realized he didn’t need to
Why not use a drone? Using a drone to inter the cave with computer connection to your device equipment below. Just a thought...If you study the sides of the pyramid's you can see the difference in stones and different formations of course. Also, either by weathering or design the patterns appearance of slanting horizontal lines as well as vertical lines from different perspectives. The horizontal lines seem to slant upward which may suggest a corridor or passageway close behind the stones. The vertical lines appearance's in the midst of each side of the pyramid May well be from weathering do to each side having Sand debris piled up along the base and higher at the center.
Bravo
So... basically they used photogrammetry to record the surface structure of the pyramid, and yet, have discovered very little. Photogrammetry is an old tech that even I've used in my university studies. You basically transform photos into a digital 3d structure. It may be useful, but not massively ground breaking in discovering the ancient construction method.
Remember this is 5 years ago, now anybody can do this type of scan with mobile and assemble in Bender
Bring the laser scanner with a good drone up there high up in the pyramid😊
Great speech
I thought he was glued to the wooden base 😂
Yukynori handsome!
I think I agree with most people hear the biggest question how are you getting the water up into the top of the pyramid. And also how are you not allowing the water to drain in this quote-unquote sealed system. I'd like to see you build this as a model
What water is that
Dear nat geo, let non mainstream egypt archealogist give talks on this. I tried to listen and I understood his words but still he didn't make any sense to me.
Itube Graham Hancock
Hang on. Jean Pierre Houdin (An architect who sold everything and shut down his business to solve this) JPHs whole internal ramp theory hangs on him being allowed to "Climb" the pyramid just once to the gaping hole in Kufus side and analyse it for 1 anomaly he knows is there which will once and for all end all those alien bs theories and verify his as 100% fact: To me it already is verified:
So how did thus guy get a permit when JPH has/is been waiting 6 or more years?
There's another theory that is very plausible. It explains how they built it and got their precision not to mention why the blocks do not match any quarries nearby. The lime stone blocks were poured. A kind of lime stone cement.
I'm not sure about the pyramid blocks but other sytes in egypt (such as the serapeum or the bastet temple) show stones that were carved from solid rock, with veins showing. That theory I think would best explain the Cuzco polygonal walls
Kafre : Let’s build a Pyramid with some crappy Copper Age Tools for Dad
Kawab: Sounds Tricky. Shouldn’t we invent the Wheel First ?
Kafre : Wheels are for Namby-Pambies ! Leave that tomfoolery to the Mesopotamians !
5 hours to climb, lucky the pyramids are not in Australia, or there would be cable cars and water slides on it.
you forgot to mention zip lines
Ancient elite humans had knowledge of basic maths and physics
What ?? So he just explain his vacations in Egypt ??
The higgeldy-piggeldy position of the hidden, or fill-in stones indicates that the precision build so many attribute to the pyramid build, was not evident in all areas.
the subtitles need subtitles read by an interpreter
Treadmil growing or moving stone ice in Egypt
Inner ramp theory rules!!!
In the pyramid are 1000 puzzles. If one is missing, we can't build a pyramid.
In other words, they STILL don't know.
I think he at least tried to find the possibilities of answer. And its 'OK' to get nothing after doing everything. He in his vedio explained a new possible way to study the ancient structures. Afterall this is HISTORY, and it never gives its all details so easily. We should keep on trying....
Wondering what the computer scientist could do with the latest iPhone LIDAR...
You ever heard of Jean Pierre Houdin? And his theory of inner ramps? So I know for sure this guy here was not the first to record the notch and the cave first.
6:15 - what IS a 3-D information?
The 'Notch" on the right side of the Sphinx's neck: :)
I have been doing some on line research about the Great Sphinx of Egypt. I can not find ANY information that discusses or explains what this 'notch' is.
To me it sure looks like a key, or something that would be turned.
Possibly to open something, a door or secret passage way.
Do any of you know what this is or what it does,....
I cant find anything about it Hiding in plain sight , there it is yet NO ONE has addressed what this thing could be. Is it a great secret that only a few know about? Edgar Casey said in a trance that great knowledge will be obtained when the great Sphinx is opened. Could this be what OPENS it??
The simple fact that it is completely over looked and NOT discussed, makes me think it is more than Egypt is willing to admit.
Now, explain polygonal masonry.
Thanks comments! Glad I didn’t waste my time aaaaaand next video
It's amazing how no one know's to this day in 2022 july 5th how the Pyramids were built 🙄
Pyramids found on Mars. Does his mean pyramids is like a teleportation platform??
Stabilization platform or the shell of an empty machine, the face pyramid on mars location is coded into the layout of the giza complex and into the first paragraph of the bible ...
0:53 Dater hahahahahahhahahaha
All that time at the Giza Plateau and the poor bloke was busy doing nothing.
Watch his eyes when he says the laser was to heavy and big. The shot is always away from face when certain things are said.
Didn't anyone notice the spiral pattern of the blocks at the top?
They plied sand around the outside pulling block off barges as they were able to divert the river to the site. Elephants, horses pulled the blocks up sand ramp.
My theory is they built the pyramids from bottom up. The other way around would be a bit tricky.
Or magnet to magnet stone
Mr河江の講義素晴らしかったです。英語全く分かりませんが…
ビコーズ＝例えばは、分かりましたw
Well he did prove they used a back fill. Which has never been fully agreed upon.
I have solved the mystery of how the pyramid construction was done. I will reveal it once i patent my idea. Be on the lookout for eureka moment soon.
What about Jean-Pierre Houdins theory of an inner staircase?
Right, and what about Bob Brier going into the notch first? I'm getting tired of these archaeology videos where they step over each others' work and don't reference each other.
Yes, they should all work together more. I'd really like them to explore Houdins theory, confirming if the staircase exist or not. Man, I love Bob Brier. I watched two courses by him. One course with 48 lectures of the history of ancient Egypt and another 12 lectures on pharaohs.
stones were molded.... so simple, it explains everything.... they new this technik like scythian, sumerian, south american... people....history is not true what we learn in the school....
For every stone on the plateau , there is another theory .
who is this guy ? Jean-pierre is the main discoverer and the pyramids were built with an external and internal ramp.
There is a theory in my mind how pyramids were created, it seems impossible that how the stones were carried and put in place, no matter how many men were doing it, but on the other hand the egyptians were very experts in chemicals, like the colors of the pictures drawn on the inner walls of the pyramids, and its not magic that they have found such adhesives or chemicals which when mix with sand just like concrete form a block of any size or shape, i hope i will get positive comments on it.
I want to become a archeologist to study mars ruins but it’s not commonly accepted Mars was inhabited yet what am I supposed to do if I want to study a field that is covered up...
Laser too big to carry? What are you trying to carry up there the Death Star?
