On the internet you have this idea that the vertical coordinate of the Great Pyramid of Giza has the same numerical value as the speed of light. This would mean that the ancient Egyptians placed the pyramid to the right place with the accuracy of 0.0000001 degrees which translates to 1 centimeter (0.4 inches).

Is it actually possible to measure the location of the pyramid that precisely or are the numbers just made up by some conspiracy theorist?
