Some of the flat-Earthers know enough physics to throw around the vocabulary, but they don’t actually understand enough physics to be compelled by the truth.
It's pretty crazy that the Earth, as seen from the Sun, about 150 million kilometers away, is just a dot; and yet the light from the Sun can somehow illuminate the underside but not the topside of the clouds as it sets.
If that's the case I'm pretty sure we're outside of it. Our oceans are the water being divided from the inner clean water of Agartha.
We're in the septic tank portion of the earth. All the waste of the world is on the surface where it interacts with the sun and environment, decomposing and recycling everything.
The real earth is viewed from inside the firmament us shit people stand on.
