Oh yes, I am quite familiar with that site. Lots of good info. It would do the REs (SEs ((Spherical Earthers)) as I call them) some good to read all the topics there.
That particular site contains a wealth of scientific misinformation, errors of fact, misrepresentation, distortions, falsifications, and just straight out lies. I spent some time reading through it, and couldn't stop chuckling most of the time.
But I just think it's nonsense that a sphere can be spinning around and moving through the vacuum of space and yet have a gas atmosphere that stays intact with Earth.
This disbelief is because you don't
fully understand the theory of gravity, and why our atmosphere "sticks" to the planet, rather than "sliding" over it (and producing massive wind fronts).
Have we EVER seen that in a lab? Not that I'm aware of.
Not in a laboratory, no. But we have seen it in a little kid's bedroom where he's playing with a spinning top, and which is leaning slightly one way or the other. And yes; there is a layer of air molecules travelling at the same speed as the skin of the top, (although due more to its surface coefficient of friction rather than the top's gravity field).
