Georgia Guidestones

The Georgia Guidestones is a granite monument in Georgia, United States. In one of the stones, a hole is drilled through that points to the north celestial pole. And consequently, by looking through the hole, the star Polaris is visible at night.

Polaris is visible through the Georgia Guidestones’ hole every night, and flat-Earthers use the fact as “evidence” that Earth is stationary. In reality, due to Earth’s axial precession, in a few hundred years, Polaris will have moved far enough away from the north celestial pole and will no longer be visible through the hole.

The hole of the Georgia Guidestones is really nothing special. It is just a hole drilled due to north and 34° up. Because the latitude of the monument is also 34°, the hole always points to the north celestial pole. This is not unlike by measuring the angle between the north celestial pole (approximated by the position of Polaris) and the horizon, we can determine our latitude.

We can easily create the same “monument” by drilling a hole pointing to the sky, with an angle that corresponds to the location’s latitude, and facing north in the northern hemisphere, or south in the southern hemisphere. And we can accomplish that because Earth is a sphere.
