If we accept the calculation model based on the speed of light, then the builders of the pyramids must have known: The speed of light itself — 299,792,458 meters per second (not necessarily expressed in meters). The number e (Euler’s number). The number φ ((1 + √5) ÷ 2). √2 − 1 (the difference between the diagonal and the side of a square). The averaged cubit (((((π−(1+√5)÷2×(1+√5)÷2))+(π÷6)+((1+√5)÷2×(1+√5)÷2÷5))÷3)). The Pythagorean theorem (3, 4, 5). The importance of consistency checks (control sums). The ability to perform reverse volume calculations. To live on Mount Olympus. 🙂 If we accept the calculation model of mainstream science, then the builders of the pyramids had barely figured out what the number π actually is, and the pyramid angles were calculated using ropes and knots.
