The Internet Said This Pyramid Theory Was Impossible. So I 3D-Printed It.（原声文稿）

This is the great pyramid of Giza, only one million times smaller.

I've built this miniature model to test out a brand new construction theory that recently went viral.

But the comments under that video were highly divided, with thousands of people saying that it was simply impossible.

So to settle the debate, I'm putting it to the test.

And if it survives this test, I'm going to personally fund a full -scale model built with the actual material and weight of the stones.

Now for those who haven't heard about this new theory it's actually quite simple. Wooden tracks are anchored directly onto the pyramid's face.

Two platforms on opposite sides are linked together via long arrays of ropes.

One platform holds the multi -ton stone, stone, while the other holds the counterweight, which can be anything from sand, water, or simply the combined weight of several workers.

To guide the ropes they used proto -pullies, but keep in mind, these pullies do not rotate, they do not have axles, and there is very strong evidence that the old kingdom used these types of pullies on a daily basis.

Now 3D printing this miniature model was a bit of a nightmare.

there. My first design failed because the platform simply kept tilting and dropping the weight.

To fix it, I tried remodeling the shoes and tracks so that they interlock.

But this design was even worse, the platform simply jammed and stopped moving.

All I had to do was make the sliding shoes just a bit longer, and now it finally works.

So now that we have the right design, we can finally test the physics.

Now to keep things simple I've scaled everything down by a factor of exactly 1 million.

The heaviest stones in the Great Pyramid average 50 tons each reduces that by 1 million and you get 50 grams.

This 50 gram weight will represent the pyramid's heaviest stones and for the lighter stones which average 2 .5 tons each will simply use this fishing sinker which weighs about 2 .5 grams.

Now to live this 2 .5 gram weight up the face of the pyramid, we simply need to add more weight on the oxidant.

But you can't lift a stone with other stones, that wouldn't make any sense.

So instead workers simply climbed up a staircase, and once they reach the top, their combined weight becomes the counterweight.

So to represent each worker, I've 3d printed hundreds of tiny plastic pucks, And if we weigh a single one, you'll see that it comes out as 0 .06 grams, exactly one million times less than the average weight of an adult male, which is roughly 60 kilograms.

Alright so let's load up our counterweight with these tiny human pucks until we reach about 5 grams.

Now let's place it on the counterweight platform and there is no movement. That means it's not heavy enough.

Now let's try 7 .5 grams and there we go it works but now you're probably thinking this system sucks if you need three times the weight on the counterweight side well that's very inefficient and you'd be right but you have to remember friction is much harder to overcome with objects that barely weigh anything in a real size model, you'd only need around 3 .2 tons, which is roughly 52 workers, to lift a 2 .5 ton stone.

Now to really see the system gain efficiency as we increase the weight, let's just go right ahead and lift our 50 gram stone.

But for this heavier stone, we can't use workers as the counterweight anymore, because we need roughly 1 ,300 of them all crammed onto a platform several stories high. That's not very realistic.

So instead they could have simply lifted 2 .5 tons stones one at a time and then use the combined weight of all those stones to lift the heavier ones.

So let's load up our counterweight with 100 grams of worth of sinkers and now let's place it on the counterweight side and it already works.

100 grams to lift 50 grams is a 2 to 1 ratio a big improvement over the 3 to 1 ratio needed for the 2 .5g weight.

But now you might have noticed an obvious problem.

When a stone reaches the top, how do you lift the next stone when the counterweight platform is now stuck at the bottom?

What once a stone was placed, you have an empty sled that needs to return all the way back down to the quarry.

By placing this heavy sled onto the stone platform, its weight would trigger the elevator to descend, pulling the counterweight platform back to the top, automatically resetting the system for the next stone.

But if wooden tracks were truly anchored directly on the face of the pyramid, wouldn't it leave markings or clear evidence behind?

Why isn't there any anchoring holes anywhere to be found on the remaining outer casing stones? The answer is very simple.

All of the tracks, pulley frames, and staircases were all anchored on a sacrificial skin protruding from the casing stones.

And once the pyramid was completed and the tracks were dismantled, workers would have simply chiseled and polished the weight out of extra skin, erasing all the evidence.

And you can actually see great examples of this on some of the lower casing stones of Mancora's pyramid, which was left unfinished.

But Egypt wasn't a forest, so where did they get all the wood?

While the polymer stone recorded that Pharaoh Sneferu, who built three of the largest pyramids in Egypt, sent a fleet of 40 ships straight to the Mediterranean to import massive loads of Lebanese cedar.

Now, Lebanese cedar has incredible compressive strength and can easily handle the weight of 50 tons or even 100 tons stones, making it the perfect material for our tracks and elevator platforms.

Another major concern people had was the ropes.

Wouldn't they just snap under that heavy weight?

Well, if you only use one or two ropes for a multi -ton stone, of course they will.

But by distributing the load across an array of 10 to 20 lines, each rope only handles a fraction of that heavy weight.

A single rope made of natural plant fibers like papyrus with a thickness of 3 inches can easily handle the weight of 5 tons without snapping.

So if you have an array of 20 ropes like this, well you can easily lift the pyramids heavier stones, some of which weight up to 80 tons.

But the real challenge of this entire system isn't just the weight, it's also friction.

Slighting wood on top of wooden tracks and wrapping ropes around static logs creates an outrageous amount of friction burn.

Without lubrication, the material would need constant replacement.

To solve this, the Egyptians could have simply coated their tracks, proto polis and ropes with a mix of animal fat, wax or other material.

This would allow the system to last for decades instead of only a few days.

Now a big issue with ramps, whether they're internal or external, is that the entire operation relies on a single lane.

So if a track needs repair or a team of pullers suddenly get exhausted, the entire traffic either slows down or halts completely.

But with elevators, you can actually fit several lanes all along the face of the pyramid. it.

So if one lane suddenly breaks down, well at least you've got other lanes still moving stones.

That's a huge deal, especially if your goal is to finish the monument during the pharaoh's lifetime.

Ramps also fall short when it comes to placing the Pyramidian.

When in external ramp you need a ramp containing more material than the Andara pyramid itself.

And when in internal spiral ramp you can even reach the peak because you're literally run out of space to turn.

But with an elevator, you simply lift it to the very top and then use ropes and rope guides to pull the capstone into place.

Alright, so now that we've confirmed that the physics do work on a miniature scale, there's just one final thing left to do. To build a bigger model.

How big we build it will depend entirely on you.

Since I'm unable to fund this project on my own, I've opened up a channel membership and every single dollar raised to memberships will go straight into acquiring timber, ropes and weights for a real size test.

I'll also demonstrate how ancient ropes were made and how they actually cut granite and limestone.
