Flat-Earthers have been eclipsed by a different group of flagrant idiots.
It sounds like a Homer Simpson fever dream, but a growing community of people genuinely believe that the world is donut shaped. No, this is not a joke, like the Taco Earth Theory. This is a real theory from really misguided individuals.
From VICE:
According to the theory, there’s a huge hole in the center of the planet that we can’t see because, Varaug writes, “Light bends and follows the curvature of the torus, making the hole ‘unseeable.’” The theory raises a lot of questions about how gravity would work, which Varaug explains with a sugary, not completely cogent metaphor. “Imagine a donut. Imagine a jam donut. Gravity acts towards the jam.”
