       | More fun facts:
       | 
       | - The Great Pyramid is a scale model of Earth, at a ratio of
       | 1:43,200 (a significant number)
       | 
       | - It also encodes its own latitude and longitude
       | 
       | - Its base perimeter is equal to 1/2 a minute of latitude
       | (1/43,200th of 360 degrees)
       | 
       | - It's aligned to true north within 3/60 of one degree (making
       | it, I believe, the most accurately aligned structure on the
       | planet)
       | 
       | These are not undisputed claims, but there is absolutely
       | something different about 4th dynasty pyramids that is worth
       | exploring. There are many, many anomalies about Giza that defy
       | explanation. Another example is precision stone cutting and
       | drilling from thousands of years ago.
       |

         | Is that referring to true North today or in 2560 B.C?

         | 
         | 3/60 of a degree is mildly impressive (Wikipedia says 4 minutes
         | of arc rather than 3), but I seriously doubt that it's the most
         | accurately aligned structure on the planet. With modern
         | technology, surely we could align something much more closely
         | than that given a good reason to do so.

       | They're only eight sided if you don't count the base, too.

         | The issue is how do you define "eight sides."
         | 
         | It's a four sided pyramid, where each side has a concave bend
         | in the middle, only really visible from a top down perspective.
         | The article contains enhanced, but completely valid photos of
         | it.
         | 
         | It is unknown if this was an intentional design aspect. It does
         | not seem to be a feature of any occult purpose. Sneferu's Bent
         | Pyramid does "not" have 8 sides, but was incorrectly completed
         | at a later date at the wrong angle, thus often used as a
         | (useless) comparison.
         | 
         | All other pyramids in Egypt seem to just be normally 4 sides
         | with no concave outer walls.
         | 
         | tl;dr The Pyramid of Giza is only 8 sides on a technicality. It
         | approximates the usual, and expected, tetrahedral shape.

           | William Matthews Flinders Petrie is mentioned as having
           | written _La Description de l'Egypte_ in the 1700 's - this is
           | inaccurate, the man was born in 1853:
           | https://en.wikipedia.org/wiki/Flinders_Petrie. On a quick
           | search I can't find mention of _La Description de l'Egypte_ ,
           | either in French or English.
           | 
           | They're also quoting a text by I.E.S. Edwards at the end. He
           | seems to be a real person, but they quote a 1975 edition of
           | his book, which I can't find on google books (https://books.g
           | oogle.nl/books?q=editions:ISBN0140136347&id=d...).
           | 
           | The mention of _British Air Force pilot, P. Groves_ pops up
           | in multiple places, but none looks particularly trustworthy
           | to me.
