I watched a very interesting video regarding the Pyramids which I thought others might find interesting - unfortunately it has an odd ad link at the start which is easily bypassed by clicking the x!
It seems that the lady is translating as she is listening, so it's not very 'smooth' to listen to, but the ideas presented are interesting.
Mentioned are comparisons between the structure of the pyramids and examples of possible technology in Egyptian paintings, and the wireless electricity transference proposed by Tesla.
Also suggested is that the 'Ark of the Covenant' was the super-conductive material stored in the bottom of the Pyramid which was used to supply electricity - and that was taken by Moses, causing the collapse of the Egyptian civilisation.
Sorry if this has already been linked somewhere - I couldn't find it referenced anywhere with a search =)http://www.youtube.com/watch?v=DHrSulXPYu4&feature=related
-.- Just double checked the links in the comment - and a 'better' version is linked. (I guess I was quite enchanted by the lady making the effort to translate).http://www.youtube.com/watch?v=tiMMERUpaNY
