The sacred architecture of the Great Pyramid has mystified many scholars and researchers, because, like at least some of the engineering, the design involves super-advanced mathematical relationships which are not consistent with the knowledge of the time. In this workshop, we will explore the significance of some of these rare architectural features of this monument. We will review how the pyramid’s thickness correlates with its mysterious spaces inside and will show how this proposal has been put to a test with the newest Muon scanning data. In the second half, I am going to discuss the possible astronomical origin of the major dimensions of the Great Pyramid and its famous golden angle. The workshop will be held interactively so that the audience can ask questions throughout and discuss the various theories proposed.
