Concave geocosmos and heliocentric sphere are visually equivalent models, with one being the inverse of the other. But the confirmed bending of light, the confirmed geocentric nature of cosmic background radiation, and the stationary surface of the Earth, collectively establish we are on the concave inner surface of the Earth cavity realm.
Stumbled across that meme on a Pinterest site iirc, when researching concave earth.
very interesting and a great speaker, thanks for sharing
