And, while it is true that the two pyramids have similar dimensions (at the bottom), the Pyramid of the Sun at Teotihuacan does not have a square base, it has a rectangular base.
The Great Pyramid in Giza is also twice as high as the Pyramid of the Sun.
Having a hard time wrapping my head around why the "opposite side" is upside down. Wouldn't you just wrap-around slide the map 180° if you wanted a straight-line-through-the-center opposite side overlay? For example, according to this, what's on the opposite side of the Earth from Antarctica is also Antarctica. Additionally, for it to be accurate, would you not have to use a different projection, like Dyson or Butterfly?
