I first heard about these pryamids a few years ago. Unfortunately I can't watch the video. The photos are amazing, I thought I'd just add a link on the original information when it came out so that some posters could compare the progress of the information just for background.
I do not necessarily agree with the information provided as I have not been able to keep updated, but it's certainly an intriguing find.
