For our inaugural Sacred Geometry International Radio episode, we are very excited to feature a fascinating conversation between independent scholar Randall Carlson and esoteric researcher Scott Onstott. In this discussion, Scott and Randall consider the potential meaning of the harmonic proportions of Sacred Geometry, as they are redundantly encoded throughout the ancient kingdom, most notably in structures such as the Great Pyramid of Cheops at Giza. Questions raised include whether our remote ancestors understood the size and shape of the Earth with accuracy rivaling modern satellite surveys? Could they have measured the speed of light in not only miles but meters per second and encoded these fundamental constants of nature into the geometry of the Great Pyramid? If so for what possible purpose? Were our ancestors aware of a cycle of catastrophe and to what lengths might they have gone to to preserve such knowledge?
