What if a pre-human civilization made them and the egyptians just found them?

#42i love this - even if it turns out to be not fully correct in the end. one thing i was wondering was if any evidence had been found about about the balloon floatation devices, and, along similar lines, if they modeled the idea that small barges atop the blocks might have worked instead of balloons.
fwiw : someone else posted this more detailed youtube video ..which has a good discussion of the rationale of the floats -- wood vs animal skin and papyrus.

#43Interesting idea, and maybe one worth investigating further. I've always liked the internal ramp theory: https://www.youtube.com/watch?v=Ws4O5LOCI68 In the end, lets all at least agree that it was human innovation and not alien technology that built the pyramids.
1. People, in general, are smarter than the ancients and civilization has progressed since then. 2. We don't know how they built the pyramids. Either aliens built the pyramids, or we're dumber than the ancients.
Umm, modern humans are perfectly capable of building pyramids or even much more complicated structures. You may have noticed that 21st century civil engineering is much more advanced than ancient Egyptian civil engineering. However, what we don't have is the level of experience with their tools that they had.

All it really takes is one genius with influence in the right ears to achieve something remarkable.

#45For the sake of the argument, let's accept "The structural engineer reckons that would be impossible as the ramps would have had to have been at least a quarter of a mile long" and ""If that happened, there would still be signs that the ramps had been there, and there aren't any."
This idea replaces that quarter mile ramp by a waterway with a difference in water level of 150+ meter and thus with 150+ meter high watertight walls that can withstand the pressure. Where are the signs that that waterway was there?
Also, how do you get the water up in that lock? Ships can move up through locks, but water only flows down.

#46Earlier quoted context omitted.
Why would an archaeologist be more qualified to guess how they built the pyramids than an engineer who studied the pyramids for years? Or are you saying we should just dismiss all of the content because you don't like the organization that published it? I question your belief that you can evaluate information based on the organization that provides it. Or at least that some popular or well-respected organization can…
Do you treat all P=NP proofs as of equal worth and spend time carefully checking them to see if they might be accurate? Or do you apply some filtering first - reputable journal etc? Discounting stories in the Mirror and Mail is a totally reasonable tactic. UK papers do not have fact checkers like US publications. UK papers very carefully report what someone says, even if most people agree that person is a wingnut and…
Sure tabloids are an extreme case and they do often print lies and garbage. Still, since you bring scientific journals into it, the scientific publication system has been shown to stifle new scientific theories that correct old ones in favor of maintaining the status quo or most popular theories of the time. So journal reputation can also be a negative qualifier.
Centralized, authority-driven worldviews are very destructive and outdated.

#47Not passing the sniff test for me. Three flaws at first glance… At the end he describes lowering blocks into place by incrementally removing bladders. This does not work. As soon as you are fully submerged and displacing with bladders you are unstable. As your depth increases, pressure increases, and your displacement goes down making you sink even faster. The good news is if you get neutrally buoyant you could poke…
What if the channel was vertical an placed at the center of the pyramid?

The entering tunnel is gently sloped but doesn't have to reach the top of the pyramid.
I guess it would be easier to build since the the walls of the channels are kept in place by the weight of the whole structure.
I don't know about the bladders though.
Re: Engineer: Egyptians built pyramids by piling rubble and attaching bricks later
#48Interesting idea.
Romans used water for mining too.
Why do effort when nature does it for you?
Two problems people raise:
Water pressure from 150m+ water column is too much. In the video they talk about dividing the hight slope channel into sections This way leaks will be also smaller.
Putting water inside. This probably is the weaker point of all.
But overall it makes sense. It will be great for a kickstarter to try to replicate it at a small scale.

We don't know what the architects of the pyramids discussed in the pub either, but that is not because we are worse at conversation.
