Flat Earth Debunked: Axial Precession

Axial Precession is the cycle in which the pole stars on the celestial sphere change over a period of 26,000 years.

That’s right, flattards! Polaris wasn’t always the pole star. 5,000 years ago, the Northern celestial pole was near Thuban in the draco constellation. In 8,000 years it will be close to Deneb and in 12,000 years from now the pole will be somewhere in the vicinity of the brilliant star Vega.

Since flat earthers seem to believe that Polaris is directly above the North Pole and is completely stationary with the stars rotating around it either on a dome OR a flat roof sky that goes on for infinity in all directions, I’m not sure how it would be able to change over a period of about 1 degree every 72 years. Flat earthers are obviously going to have to explain the physics that allow stars to switch from stationary to moving as the celestial pole changes places.

In reality, we do know what causes Axial Precession… it’s the gravity from the sun and moon acting on the earth’s equatorial bulge. Wait, GRAVITY?? Then how can the earth be flat, then?
