"Egyptians used internal spiral ramp to build pyramids" Topic

Not definitive, but it checks all the boxes. Build a ramp out of the pyramid itself, use it to haul stuff up the sides, and then fill in the ramp when you're done, working your way back down. Brilliant!

I like the hypothesis that they poured the stuff around it using molds etc. Why not?
Every theory is looking at convincing people who have no idea.
I know nothing, but I have mixed Sacrete in a wheelbarrow. So, 👍🍺🍺🍺
Works for me.

That mysterious Coral Castle in FL was made out of coral concrete. The huge blocks have mold forms visible in the sides (and I'm betting the larger 'stones' are hollow, making them lighter & easier to move) as well as 'puddling' consistent with poured concrete (some people claim it's because he melted the stones {rolls eyes} )

For something barely care about, got watching many History for Granite videos on the pyramids. They certainly got them up there somehow without machines or Aliens.

Well they must have called "The Guy".

Have been to St. Augustine Fort in Florida. It was a surprise to all when the cannon balls just stuck to the fort when hit.

The ramps would certainly make it easier for the imported woolly mammoths to haul the stones up.

Since I was a little kid I have constantly heard new theories of how they built the pyramids. It's a whole cottage industry, coming up with ways they built the great pyramid. We should probably just ask AI to settle the matter.

Dinosaurs have feathers now. I wonder what I would find if I did an inventory of things I learned that have not changed.

The only way to settle the matter is probably reenactment. Someone is going to have to go build a bunch of pyramids using the mostly likely proposed techniques and tell us which work best.

We were discussing something similar the other night.
All this nonsense about aliens, etc comes from the disrespect people have for the past. Theres an automatic assumption that "we" are smarter than them. If anything, I believe that we're a lot dumber.
But consider that Pythagoras was a bit of a mystic. Look him up. His "secret society" was influential. His famous theorem was a secret, kept by the society.
Is it that much of a stretch to assume that the Ancients were very well versed in mathematics, but kept their principles a Secret?
I find it much easier to believe that a secretive guild of architects and "philosophers" knew darned well how to build pyramids than that little green men (grey men?🙄) did all the heavy lifting. Why would they?

If anything, the pyramid is a simple monumental structure to build. Just watch any kids with blocks. At first they'll try to build a tower, one block on another. It falls over, or gets to the point where the top is out or reach (and then falls over).
Then they'll build a wall, placing straight up towers side by side… and those fall over.
The they'll hit upon overlapping the blocks so the wall is more stable; but they can't overlap the end bricks, so they end up building a triangular "wall."
Then they try making it into a building… and that's when they start with an outer wall with concentric smaller "walls" inside it, onto which the blocks are added, with each layer having a smaller and smaller array of blocks. Finally, a single block is at the top— Tada! Pyramid!

For the full-sized pyramid, the rest is just basic mechanics— wedges and rollers and pulleys to carry each layer of bricks up to the next level. But the design is basic and the most stable shape possible. Duh.

How? Greeks ruled Egypt for 300 years and Thales, Herodotus, Pythagoras, and Plato travelled to Egypt specifically to study. It appeared that the Egyptians by then just didn't know how the Great pyramids were built.

That said, if you've ever visited the valley of the kings, you'd know aliens weren't involved. The paintings and decorations, while impressive are not special. Look closely and you can see human mistakes.

Just as the great stonemasons of mediaeval Europe kept their secrets close to hand, the Egyptian secret of the pyramids could have been the same one. The secret is, that stone blocks don't need to be lifted. They can be manufactured in place by pouring the individual elements of an amalgam slurry into a mould. This is especially easy with sandstone but can be done with granite too.
