The latitude of the Great Pyramid of Giza is approximately 29.9792458°N. This coordinate is often noted for a curious similarity to the speed of light in meters per second, which is 299,792,458 m/s, but this is considered a coincidence. The pyramid’s latitude is just one of many lines of latitude that pass through it, and the exact location can vary slightly depending on the specific point measured on the pyramid.
The speed of light in a vacuum is exactly 299,792,458 meters per second. This value is defined by international agreement and is used to define the meter as the distance light travels in a vacuum in 1/299,792,458 of a second. This constant is fundamental in physics and serves as the upper limit for the speed at which information, matter, or energy can travel through space.
