The pyramids are made out of concrete.

There would be some smaller stones left from either method, but your site is a more feasible argument for the precision in cutting, the relative ease of construction.
I suppose I'll encounter many theories and controversies and have to sort it out and not completely solving it. It was interesting your site claims the wheel hadn't been invented yet. If so, it wasn't too long before it was.
I actually, when prodded, remembered enough physice to understand how the levers worked, but I never was good at spatial diagrams, a diagram of the view from the top was too much for tonight.
Then I got sidetracked when I read the GP was the only remaining edifice of the seven wonders of the ancient world. So I had to go look up the rest thinking the Temple in Jerusalem (no) and Hanging Gardens (yes but may have been in Ninevah) and the rest are mostly gods or burial monuments.
I should just keep my musings out of it for now. Thank you for the link.
ASB, I had to look up where you got your screen name, Roman senator, consul, philosopher, b 480 AD I think. Also saw a couple of your posts here about your book on EMP. That is one subject on C2C that is scientific. It is George Noory's activist endeavor. Also saw your book and author. Can't do much more tonight but will check out some reviews on amazon.
EMP's are one scary subject and only the strong and mentally equipped people could prepare and withstand the chaos of such a cataclysmic event, either manmade or through solar flares or other natural occurrences.
