There actually is some curvature/dishing/something non-planar in the faces of the Great Pyramid, a lot bigger than 4 mm. It can be seen in the shadowing of an aerial photograph alleged to be from the 1940s:
The middle is farther away than the outer edges. I hope the color-coding is obvious.
Here Martin.au got hold of the raw laser data and posted some cross-sections:
There was a very long discussion of the GP and its measurements and their possible meaning at talkrational.org.. Since the casing is mostly gone it's difficult to take what we can measure and convert it to measurements of the GP as-built. Febble posted a very good summary of the problems with the older surveys that seemed to indicate some special meanings of the as-built measurements here, although you might need to learn a lot of background to appreciate it fully.
Bottom line: the available evidence clearly and unambiguously indicates that there are no meaningful numbers (year length, polar radius, etc.) encoded in the GP.
The Pyramid is located at the exact center of the Earth's land mass. That is, its East-West axis corresponds to the longest land parallel across the Earth, passing through Africa, Asia, and America. Similarly, the longest land meridian on Earth, through Asia, Africa, Europa, and Antarctica, also passes right through the Pyramid. Since the Earth has enough land area to provide 3 billion possible building sites for the Pyramid, the odds of it's having been built where it is are 1 in 3 billion
I don't know of an easy way to check if this claim is true. A glance at a globe suggests that Egypt might indeed fit this description. However, the odds of the Egyptians building the pyramids in Egypt are not 1 in 3 billion. It might almost be considered a certainty.
Well, Ray Martinez (AKA Cold Foreign Object AKA WIllowtree) is a GP woo-ist, and the length of the longest land meridian has a thread of its own here: Longest Land Meridian. And, of course, the meridian claim is false.
