You mean Schimttidy? She is playing a charecter. She is a satire channel. She isn't serious. about thinking this...however, there is a group of people called the Flat Earth Society (I think that's what they called themselves) that have a thing going with it, and I think some of them might actually be serious...apperently, NASA is actually tricking everyone, and the horizon line is just things getting too far away to see, and they have an explanation of how the gravity works that I'm not really sure about. ANyways, I think the Youtuber you are referring to (Schimttidy) was just making fun of these people. Unfoutunatly, a lot of people don't realize that, and made fun of her for trying to show in her own way how ridiculous the whole thing is. So, PLEASE stop saying that she has no brain or whatever. Its meant to be a joke.
