The question of just how an ancient civilization—without the help of modern technology—moved the 2.5 ton stones that made up their famed pyramids has long plagued Egyptologists and mechanical engineers alike. But now, a team from the University of Amsterdam believes they've figured it out, even though the solution was staring them in the face all along.


It all comes down to friction. See, the ancient Egyptians would transport their rocky cargo across the desert sands, from quarry to monument site with large sleds. Pretty basic sleds, basically just large slabs with upturned edges. Now, when you try to pull a large slab with upturned edges carrying a 2.5 ton load, it tends to dig into the sand ahead of it, building up a sand berm that must then be regularly cleared before it can become an even bigger obstacle.


Wet sand, however, doesn't do this. In sand with just the right amount of dampness, capillary bridges—essentially microdroplets of water that bind grains of sand to one another through capillary action—form across the grains, which doubles the material's relative stiffness. This prevents the sand from berming in front of the sled and cuts the force required to drag the sled in half. In half.


As a UvA press release explains,



The physicists placed a laboratory version of the Egyptian sledge in a tray of sand. They determined both the required pulling force and the stiffness of the sand as a function of the quantity of water in the sand. To determine the stiffness they used a rheometer, which shows how much force is needed to deform a certain volume of sand.

Experiments revealed that the required pulling force decreased proportional to the stiffness of the sand...A sledge glides far more easily over firm desert sand simply because the sand does not pile up in front of the sledge as it does in the case of dry sand.


These experiments served to confirm what the Egyptians clearly already knew, and what we probably already should have. Artwork within the tomb of Djehutihotep, which was discovered in the Victorian Era, depicts a scene of slaves hauling a colossal statue of the Middle Kingdom ruler and in it, a guy at the front of the sled is shown pouring liquid into the sand. You can see it in the image above, just to the right of the statue's foot.

Nasa mga drawing na pala ang sagot...

Buti na lang nakita din nila...

Kung hindi... Akalain pa din na Alien Technology ang ginamit nila...

bwawaahahahahah............sa dinami-daming theory at conspiracies...  nilagay lang pala sa cargo at binsasa ang buhangin?  :D malamang pag di nadiscover ang sagod another ancient alien tech. na naman  :))

And how were they able to put the 2.5 ton load on the sled?

At the end it can always be traced sa kay newton...

impressive... ancient civilizations knew the basics of motions and machines... they have levers, pulleys, knew friction etc.   so another long time mystery is finally explained... thanks for the share...

 :think: honga ano.. paano nga ba.... baka gumamit ng malaking lever... hmmm... magaling naman sila mag imbento ng paraan...


Offline naruto789544

just recently, another theory came up with aliens again at the forefront of the explanation... well, basic machines have been in used since time immemorial and i think it really was possible...
