And, all these years, I was told… and believe… that these channels were perfectly straight and pointed to constellations so the spirits in the afterlife would know where to go. Thanks for clearing that up.

“The search isn’t just for answers; it’s for better questions.” Bravo! Thank you for your dedication to this. My mind, happily spinning with new questions, thanks you.

Dude managed to talk about a hole in a wall for 45 minutes

you've convinced me 100% that no one has any clue what they are talking about in regard to the pyramid and it's true function

The work you do is simply astounding and hopefully encourages people to think and explore in similar ways! Approaching things in an open minded fashion, instead of looking for answers that support your preconceived conclusions is the way to move the understanding of the pyramids forwards. I hope your findings will get support from the 'experts' too, instead of being dismissed based on credentials & going against the narrative. Thanks for everything you do and I very much look forward to future videos :)

You always give credit where credit is due. You recognize on who's shoulders you stand. I'm impressed.

43:05 "The ventilation was not available until the construction was nearly complete." I agree, but you explicitly state that the holes were left uncut for the purpose of avoiding damage while fitting the ceiling stones. And that's incidentally also the exact moment when ventilation for the workers would have become necessary. (With the ceiling stones missing, the air would have come through the gap at the top.) So they could have put the last ceiling stone on, and within the hour proceeded to make the first drill hole into the casing stones of the King's chamber. And for the "Queen's chamber" the holes were never drilled because they knew (or were reasonably certain) that they wouldn't bother doing any further changes to it after putting its ceiling stones in place. And the course of stone where the Queen's air channels end would tell us exactly where/when they decided to fully abandon using the Queen's chamber. Curiously that's _above_ the King's chamber, and pretty precisely aligns with the last layer of releiving slabs and the vaulting stones. Almost as if they waited to see if the alternate construction technique for the King's chamber worked out before committing to fully abandon the Queen's chamber.

The benefit of being a ‘lay person’ is that we ask simple questions without the interference of bite sized knowledge. If the channels were indeed created for the souls to ascend then obviously the ancient creators believed they were necessary routes; yet perfectly carved hermetically sealed granite sarcophaguses were no problem for the soul to escape from. I find more and more that ‘experts’ indulge the viewers with what they want to hear, presented as fact, rather than facts themselves. I love your work and the way it’s presented.

From an academic point of view, this an incredibly courageous essay. You constantly seek to put ambiguities to bed with logical evidence based argument. You are also on record as having a profound respect for the limits of your knowledge. Not having done the reading, or the crawl work, to verify your numerous claims, I am inclined to accept them as read BECAUSE of your general attitude toward the limits of your own knowledge. I feel certain of this because I have WITNESSED you drop pet ideas in the past in light of new evidence. Your videos taken as a whole, are a showcase of learning, curiosity and intellectual generosity. You are a champion of clear reason and civilisation in a world turned upside down by barbarism and sadistic cruelty, and an internet saturated by egocentric opinion and lazy thinking. Respect! I often wonder if Egyptology is a haven from the froth and bubble of life, but the politics of Egyptology put the lie to that, and the ancient Egyptians were a passionate and dynamic people, who would laugh at the idea. What I find most attractive about your work and style of communication, is your indefatigable humility toward the unknown. It gives me hope, that we humans are capable of reaching our highest ideals. Thank you for your work. Carry on good sir!

We're gonna need an in-depth version of that tier list with explanations, thank you very much.

Dude the comments are epic, I've been down here reading all them, everyone has great input, look at all the fantastic folks you've drawn together, gotta love it!

I don't know how you do this, time after time. Seeing something that everybody else has missed. It's incredible to me. Look forward to the next one. Thanks!

this is a PHD thesis level, u deserve one ;)

Another outstanding video...created by simply noticing simple things which have remained in plain sight for millenia. Thank you.

Undoubtedly, this channel stands as a pinnacle of Egyptological discourse, eclipsing the scholarly contributions of the vast majority of its contemporaries in the field. For years, we have been indoctrinated with the belief that these channels were impeccably aligned and directed towards celestial constellations linked to the afterlife journey. Many thanks to History for Granite for the elucidation provided, dispelling these long-held misconceptions. This video resonates with the imperative that we must elevate the quality of our inquiries. Bravo indeed!

Best channel on Egyptology by far. Puts the vast majority of Egyptologists to shame.

I really like how critical and detail oriented you are. Keep up the good work

Another wonderful, thoughtful and thorough video. Thank you for all your hard work. Looking forward to the next one!! All the best

Prefab channels, opened with a tubedrill and dressed squared after the construction of the chamber,... Remarkable observations, more questions. Love it!!!

I've never really cared or been interested in the pyramids until watching every single one of your videos - your excitement and enthusiasm is infectious. You can hear the bitten tongue in calling Lehner and Zawass "gentlemen". I love the fact you made a hype-train video precursor for this release. You are a good person. In an era of absolutely complete unenthusiasm, I will certainly watch a channel about a topic I never cared much for just to see the devotion you put into every video.

Simply The Best channel if your are looking for new scientific/credible perspectives on old Egyptian architecture/"mysteries". This content is a must for all who appreciate an excellent scientific idea!

Always so stoked to see an upload from you ❤

The best show on UKposts thanks for the effort dude

These people have written countless books, gotten solid funding and support…..and you just crush them with obvious facts. Great stuff :D

Absolutely awesome research with a keen eye, an open mind, and sound logic! Great job! Thank you!

If I'm not mistaken, you mentioned in one of your videos that the pyramids were left open some time after the burial. So, there might have been VIPs visiting the chambers. Those are the ones enjoying better air conditions than the workers, right? Hm, I guess the inner structure was better accessible when building it, so maybe the conditions weren't as bad as we think for the workers. That's an unelaborated guess, I know nothing about the construction steps. Great work, thank you very very much!

Egyptian builder: "We don't need to finish these channels, no one will ever see them." Robots 4500 years later: 👁👄👁

hands down some of the greatest content on youtube ever created. I commend your deep research, critical thinking and credible hypotheses.

One of the best channels on youtube. Always a pleasure.

The thoroughness of your review and careful methodology of building your hypothesis and conclusions was compressive. Thank you for this contribution.

This channel has set a new higher benchmark in regards to scientifically questioning pyramid construction

Imagine if it turned out that the pyramid was just one massive bong

I appreciate the effort involved with the making and producing of this video

Thanks, so busy it took me almost 3 days to get to watch this, had to clear the To-Do list completely, weekend went poof lol.

I love how you're showing all that writing like it's on the inside of the pyramid when we both know it's not there's no writing inside the Great pyramid

Your freedom to explore your interests unhampered by Egyptology dogma coupled with exacting observational skills makes for compelling and intelligent disccourse. Praise!

So much looking forward to this - your content is always awesome

thrilled for the next ones. that ending gave me goosebumps

Very interseting indeed! More solutions but more questions, preserving the beauty and mystic of the Egypt i love.

This adds so much clarity to the misconceptions I had about this feature of the Great Pyramid. Much appreciated. Can't wait for further revelations about this fascinating monument.

This channel is literally at cutting edge of bringing the ancient past to life. As you explained the 3 different cuts I had a sense of truth that I haven't felt in a long time. It all makes sense now. As you were explaining, I could literally see them cutting the stone in my imagination and it really felt like I was there. I can't wait for the next video. Keep up the good work 👌🏾

Fantastic!, great work, loved the history & the reasoning, i especially like how you said this makes us ask more questions. Thankyou!❤😊

This channel is such a gem, but I keep missing the livestreams, LOL!

I am litteraly amazed by the unfinished corner of the queen chamber's entrance. A simple and pratical solution, left as evidence of their labour, by workers lived thousands of years ago.

This lends more credence to the pyramid being used regularly post construction as opposed to corpse disposal. Love your work

I like your idea that we still have questions amongst a seemingly perfect explanation as to why. Very good video sir.

Truly fascinating and a most logical solution. Concluding the Queen's chamber as unfinished based upon the blocking stones remaining in place and the "roughed out floor", not dissimilar to modern home building, is a far more plausible explination for why the venting holes would not yet be opened. Not yet having viewed the follow up videos, my guess is that the vents would allow for better interior climate control to prevent mold, mildew, salt or other build up/ condensation. Additionally, possible control for interior atmospheric pressure as well to avoid internal pressure shifts over the millenia to cause cracking to the bricks or shifting to occur. Finally, I applaud you for going back to and relying on the oldest, first person documentation/ description of what was seen and found. As they had no dog in the proverbial fight as to metaphysical meaning of these items, they had no bias to filter their information through. They were simply reporting what they saw, what they found, how they found it, and (if they displaced something) what changes they made for future researchers. Bravo!!

I think in one of your other videos you mentioned the cult of the Pharoah would have priests worshipping in the pyramid, so the air channels are presumably for their benefit, and to allow incense and lamp smoke to filter out, considering the high rate of air flow you mentioned in this video.

Ancient laundry chutes

The fact that the holes are directly opposite each other, and the same dimensions, and the corners of the last few cm are precise might suggest there was something unknown spanning them.

Very impressive work! You consistently deliver the most objective, fact-based, and logical analysis of the old kingdom pyramids, and I can't thank you enough. This is an amazing observation about the shafts having been opened after construction. I think your conclusion here is sound, and this is a really important finding. Proving a few things, the most important of which is, despite the countless people who have pondered the pyramids, there are still many very clear pieces of evidence in plain sight that have not yet been correctly interpreted. Your point about coming at the problem with an open mind is exactly the challenge, almost everything we can observe is viewed in the context of the presumptions we make, presumptions upon presumptions sometimes. If one approaches it with common sense, the answer will be elusive. Rhetoric like, "everyone knows they were tombs" and "they were aimed at these stars", as if either factually precludes the countless other bogus suggestions that have been made. To me, this confusion presents an exciting opportunity. The only way to approach this problem is with an empty mind. Which is where I come in. I think there is evidence of another practical function of the shafts, in addition to their very clear function as ventilation. There is a viable theory that may hold water. :-P From the photos, I see a few things. There was a recess dug into the stone course at the top of one of the shafts. This wedge-shaped cavity interfaced to the shaft opening at the bottom inward face of the recess, which seems consistent with water use - an area (recess) to accept water and form a pool, and for that water to drain entirely down the shaft without pooling or other obstruction. Something that functions simply as an air shaft need not incur this engineering expense. But there is a lot of other obvious evidence: 1. If one were to put a garden hose down either shaft, the water would flow from that point to the subterranean chamber without any significant pooling or obstruction, nor any places to significantly "leak" out of the pyramid via some other path. A lot would absorb into the dry stone, but that isn't my point. 2. Every part of the path the water would take is engineered for water flow: - From the photos taken inside the shafts, the chisel marks are reasonably consistent with the flow direction, especially around corners where the flow would have been more turbulent. - The portcullises are designed to seal toward the interior, vs. the exterior of the portcullises - hinting that they could have been designed to resist water pressure and allow the room to fill with water. the two shafts enter the room below the lip of the sarcophagus - the passage into the room is also consistent with this height. 3. Every part of the path water would take shows evidence of water and sediment erosion. - There appear to be significant erosion marks -all in the direction of flow - This abrasion stops at a consistent height on both sides of the shaft. - Judging by the abrasion in some spots, it seems likely that not only did water flow, but that water flowed for a significant time. - The incline of the shaft, combined with the incline of the entire path from the top of the shaft to the bottom of the subterranean chamber, is absent of even a single location for potential pooling, all with significant erosion. - The erosion gets greater toward the bottom of the shaft and the bottom of the structure, both consistent with the accumulation of larger and more debris that has passed a particular location. Of course, there are some challenges with this theory, like, why seal the room if they didn't want the water level to exceed the height of the sarcophagus? But we don't have the complete portcullis stones intact, so it is difficult to assess whether this could have accommodated this amount of water flow. If not, the only explanation for water would require that it fill the room completely before draining into the gallery, which would draw into question the alignment of the sarcophagus and the height of the shafts. Again, we don't know that is not the case. The question of how water could have come in these shafts: if this theory is correct, water was either attained from rainfall and channeled onto the shafts by a sort of a gutter in the outer casing stones, which, at the time, would have periodically produced significant flows of water collected from the watershed represented by the top of the pyramid. Alternatively, the ancient Egyptians had the technology to elevate water to supply the shafts if that was necessary. The question of why: To me, it feels like an elaborate soul house (super-popular with the ancient Egyptians). This theme of the river being central to life and the afterlife seems to have been central to how ancient Egyptians thought. But it also demonstrated the height of their knowledge and technology. I would love to get a comment or two, to help me debunk some of these conclusions. if I can't defend my thinking, I'm probably not correct. Thank you again, my friend, for another amazing episode of History for Granted. And thanks to anyone else who took the time to read through this comment. Cheers!

So, if the Queen's Chamber is unfinished, then we can assume the pyramid had at least one major design change. The fact that the air shafts exist in both chambers probably means the King's Chamber is a revised Queen's Chamber and the change was known early enough to cap off the vents 15 meters from the outside. It makes you wonder which features of the pyramid only exist as a result of the revision and which were original (and if switching from underground to the Queen's Chamber was actually the first revision). The grand gallery certainly wasn't necessary to build the Queen's Chamber. Perhaps the granite plugging stones were in the original plan because there were to be no portcullises and perhaps the well shaft was always going to be the way out.

I watched this only once (so far) but if I understand correctly, the point you are making is that the shafts are most probably for air circulation, and the openings of the shafts in the King's chamber were cut after the construction was completed. So, they were built to provide air to the persons that would enter the chamber and spend some time there, which brings us to ask the "better question": if it was a burial site, why would they build such well-planned air shafts and put so much effort into them? In other words, if the chambers would have visitors that needed fresh air, who could be those visitors and why would they stay in the chamber for extended amounts of time? Therefore, assuming that the shafts are indeed for air, and openings were cut after completion, the whole purpose of the pyramids must be reconsidered. There were always suggestions that they might be for religious initiation practices but the details you pointed out provided more support for such theories. I am looking forward to the next video.

1) Classical Egyptologists have become "Big Idea Guys" and "Political Players", people with vested ideas and constituencies. 2) The detail focus on the opening, in ancient times, of the Channels is refreshingly prescient. Outstanding !! 3) The King's Chamber was not sealed à la Tutankhamen, but designed to breath, to be accessed and to be used by the priesthood. It is that simple. 4) The wealth of Pharaoh Khufu was never in the King's Chamber. Pharaoh Khufu does not follow Tutankhamen.

This is magnificent work. I greatly admire your thoroughness and reasoning!

So refreshing to have someone with an open mind, as opposed to many other so called Egyptologist who only live in their own mind set.

I live in cairo, so if you need photos of something specific just let me know. Great work dude keep it up

A fantastic and logical explanation as you take us through your reasoning without agenda. Thank you so much.

The dog legs in the channels are clearly human error before the alien engineers corrected them. lol thank you for a good quality explanations with clear supporting data.

Ancient Architects relased a video a couple days ago explaining a theory on what the Grand Gallery was used for. Now this video! Great week for ancient Egypt

Seeing what others have dismissed or not even thought of is a valuable attribute, and this video is simply one of the finest on UKposts, if not ever. Well done, and thank you for such an in-depth look at these shafts.

Lovely explanation! I'm looking forward to where this trip goes!

Id love to see a really in depth video on the subterrainian tunnels under the pyramid. The large unfinished chamber intrigues me most. Theres talk that water once filled the tunnels. And apparently theres a much more expansive system of tunnels than i previously thought. Please tell us more

We know that church crypts used to be constructed to allow for constant air flow. This would allow for minimal decay and optimal preservation of corpses. It is also possible that perishable goods, like foods, were placed in the chamber at the time of the burial. So the air flow would allow them to dry and thus prevent mold.

To say they are air shafts only makes sense if they were open to be used as air shafts.....since they weren't open, then we are still no closer to working out their true purpose. Dixon had to break through solid rock in the Queens chamber to open them, so they weren't just plugged up either.

Brilliance never fades. Thank you for the light of your insight

Trying to find information on the pyramids that isn't pure speculation or opinion so that I can form my own has proven quite difficult and time consuming, thanks so much for sharing what you've come across👏

It is obvious they knew sooner or later they would have to wire tv antenna cables and they knew it would be a nightmare to go through all that rock

Dude, you are singlehandedly creating huge interest in the pyramids. Egypt should let you film the pyramids up close with drones like you wanted to do. Any discoveries you make amps up public awareness and interest which is very good for tourism.

You’ve become my favourite UKpostsr for this content bro - love how you tear apart all the nonsense out there. (2nd is science against myth - worth a visit)

What a great piece of work, revealing in one word. thanks

How could anyone NOT watch this till the end?!

25:08 "as above so below, I believe someone once said." made me smile. Thank you.

You never cease to amaze me, just like the pyramids do. Your integrity and openness of mind are what Egyptology has been sorely missing for far too long.

Marvelous explanations! I don't regret watching this. Thank you, thank you, thank you!

I want to thank you for the incredible amount of time and effort expired in bringing us this information. I found it both fascinating and a remarkable testament to the architects of old, with their tremendous thirst for knowledge, incredible dedication and their amazing attention to detail. Be safe and take care

Been waiting for this one since you teased it. Great work and thank you.

For me, definitely air shafts, remember the Egyptians used oil lamps which burn oxygen, if Khufu was laid to rest within his chamber there would have been a huge ceremony with many important dignitaries participating maybe over a few hours and thus would require a comfortable atmosphere to deliver Khufu to the afterlife.

I think you do a great job of following logic and putting to rest the more implausible theories without using a "debunking" approach. Those who need reason most, quickly shut down if they feel attacked. This was an excellent excellent essay.

Amazing love your channel and always watch to the end xx

You,Night Sacarab and Ancient Architects are the best channels on Egypt. Keep it up!

Glad to see that you're back. Very cryptic statement that the channels were for air flow, but not for the workers (if I got that right). Then, for whom? I guess we have to tune in next time, same bat channel.

Brrrrrriallliant as always, the best quest for an answer is better questions that come from it

Amazing video. Love the longer form.

This is a great step forward in understanding the pyramid! Your discovery that the shafts were first sealed and then opened in a final step is very interesting!

Thank you for so eloquently addressing how experts often portray themselves as having understanding beyond the reach of most. I share this belief that they do not, and hearing someone else say it is music to my ears. Spot on!

thank you so much your work and presentation is excellent

as usual, great work. i admit i was, prior to seeing this video, convinced by the pharoah's soul explanation, but you arguments are utterly damning of this interpretation. of course two shafts more suggests air going in and out rather than a soul meeting a choice of exits. i am reminded of the mysticism once attributed to hieroglyphs versus the later discovery that they were just script used for practical communication.

Love your keen eyes insight. Excellent work.

Still don't see why channels are not straight. Are they steering around another space? Engineers generally don't prefer random curves if they are seeking the shortest distance to the surface.

I found this in depth, detailed lesson fantastic! And I thought I was up to date on the latest pyramid observations and theories. Still wonder about the power/tesla connection 🤔 Subbed 👍🏻

Thank you for your work. Amazing channel 🙌

Truely an remarkable eye for detail! But I have spotted a flaw in the "Ventilation theory": The air-flow works by the upward angle with a chimney-effect. But the chamber was sealed off from the Grand Gallery with several blocking stones on different locations. There was no air flow other than through the shafts themseves. So it would have been nearly nonexistent. Hence either the ventilation was a necessity in the building process when the chamber was open like today. Otherwise the channels could have been part of the final sealing mechanism. Considering the shafts in the queens chamber unfinished, the Great Pyramid seems more and more like a work in progress with at least three stages: a classical mastaba with the underground chamber, the "first stage" Pyramid with the Queens chamber and finally the expansion to its present shape with the Kings chamber. Thank you for your great work!

I will go to Egypt next month for the second time in my life. And this time I will look at the hole and think, Air. Thank you for all you have done to uncover the secrets of the pyramids.

BRAVO!! It is SO INCREDIBLE how you tower over other content through simple (yet critically important ) observations of the stone. The cuts are the key and while i find myself sheepishly hoping for some dramatic reveal that the pyramid is a tomb that was built through the use of a ram pump which is designed into the structure itself… I’m still happier standing on logical discoveries that show it to be a wonder of engineering in every respect. It does seem that your theory only further creates room for the idea that the pyramid was enlarged. i’ll have to look for more of your videos discussing the assertion that there is an internal ramp. Maybe you could point me there? Thank you in advance absolutely love your content and careful dissection of your subjects. Best in class!!

Another impressive and fascinating video. Thank you.

Excellent work, this is the best video on the channels of the great pyramid ever! Very well made

Well that certainly didn’t disappoint, that settles the shaft mystery once and for all. It’s been there all along staring everyone dead in the face, can’t wait for what’s next, love this channel.

very good video. very good explanations. very good at asking/answering the right questions. indeed who was the ventilation for and why? looking forward to the next video.

Oh my wordy word!!! You are a damn genius god, my friend. I wish I had found you years ago. But better late than never. With just the few videos of yours (this one included,) that I have been blessed to watch. Have elevated my understanding and supported my belief of what I have always thought the great pyramid was. Please under no circumstance at all should you EVER give up on this world altering (maybe not today but soon,) information. Your in-depth detailed analysis is going to become part of the new basic understanding of the history of this area.... May you and yours be blessed by the baker's dozen dear one! Once again, THANK YOU!? 💙🇦🇺
