The great pyramid of Giza weighs around 6 million tons https://weightofstuff.com/how-much-does-the-pyramid-of-giza-weigh/

An average human can apparently develop about 200N https://www.ccohs.ca/oshanswers/ergonomics/push1.html

Meaning that an average human would need a lever about 3×10^8 m long (considering a 1 metre load arm) to move the pyramid.

Do you find this credible?

ETA: some people think I'm serious. This is quite the flabbergast.

Don't worry I got what you were putting down. People can be very reactionary with their downvotes here, if your joke is too subtle it can fly over their heads.

It made me smirk! For my reference, how many zeros is that (I'm shit at maths but want to try and imagine such a long lever protruding into deep space)?

[–] drolex@sopuli.xyz 5 points 11 months ago (1 children)

8 zeros, so 300 000 kms (but I've probably messed up somewhere)

That's almost as far away as the moon! Therefore, the only logical explanation is ALIENS

Take that scientists!

I'm going to go out on a limb and say i don't think they found the pyramid whole and moved the entire thing. I think they took small pieces, possibly block shaped and moved those one at a time

[–] drolex@sopuli.xyz 7 points 11 months ago

I would never have thought of that! But I still don't understand how these satanic Duplo work, so who am I to judge

You're gonna need a bigger load arm. The pyramid is way more than a meter across.

[–] drolex@sopuli.xyz 1 points 11 months ago

How much more? One metre, tops?

The ancient Egyptians utilized neither wheels nor work animals for the majority of the pyramid-building era, so the giant blocks, weighing 2.5 tons on average, had to be moved through human muscle power alone. But until recently, nobody really knew how. The answer, it seems, is simply water. Evidence suggests that the blocks were first levered onto wooden sleds and then hauled up ramps made of sand. However, dry sand piles up in front of a moving sled, increasing friction until the sled is nearly impossible to pull. Wet sand reduces friction dramatically beneath the sled runners, eliminating the sand piles and making it possible for a team of people to move massive objects.
