Hope they used some rebar.

If you look at it as a logistics problem this Theory makes a ton of sense.

If I had to build a pyramid in the desert 4000 years ago, that’s what I’d do. The alternatives would be a big bother.

Come on, man! It’s aliens. It has always been aliens.

Or not

The GGG topics since last digest ping, and btw, notice this current topic is the first GGG in the 4 millions!

It seems like Egypt has high quality limestone to make the lime component of concrete. And the area is obviously not in short supply of silica.

Is it even possible? Yes, it is.

I thought the discovery of Wakanda had settled all the ancient African technology issues.

Wakanda has western-made old tires and western-made cigarette lighters, along with western-refined gasoline. That's their African technology.

Straw maybe

I wholeheartedly agree. The hypothesis has the advantage in being 100 percent compatible with all the other serious hypotheses that are out there, and a number of the ones that are hard to take seriously.

I found out about JD's book way back when from the late William Corliss (a kind and patient correspondent, for which I'm grateful) wrote about in his Science Frontiers newsletter and gift shop. The way he had his avocation figured out, I wonder what heights he might have hit in the internet era.

Very good!

First they used bar, then they tried rebar.

BTW, while trying to write that last, uh, what passes for a joke, I found this really nice page I’m about to save as HTML.

No, no the quarryies are fairly clear for many of the pyramids - at tleast those near Giza to actually quarry and move simple rocks.

BUT!

It seems that it would be far easier, far cheaper and faster, to actually quarry and move the outside the rectangle blocks as two layers of rock , and the line the internal hallways and tunnel rocks of the central ramps and burial rooms. Then fill the rest in between with chips and small rocks and irregular rocks and sand. The outside layers form the shape and retain the loose rocks and sand inside the visible walls.

First they used bar, then they tried rebar.

Of course!
You can't rebar, until you've drunk out the first bar.
