''No we're arguing about established scientific experiments here!'' You don't want to believe established science though, gravity and the fact that the earth is not flat was established long ago, scientifically. Do you really not see the flaw in your logic here or are you just being a dishonest liar as usual?
I don't think they are lying. I went through some of their older posts in the thread, and I'm under the impression that they are messing around, hopefully not genuinely disturbed.
On an interesting side note, there was a topic a grad student from Stanford I want to say, proposed a few years ago, where they said that all bodies in the universe are made of yoyos, and it held pretty well mathematically under ideal situations. The real flat earth believers use that kind of pseudo logic to find specialized circumstances inside of the broader acceptance of how things work, to come up with interesting ideas like that. They are at least useful in that you can question why it all makes sense if all of the planets are yoyos and learn something from it.
Notbatman is essentially invoking the religious argument, that everything is wrong because. You don't need to back up an argument based on faith. We can't prove otherwise because we can't come to an agreement on any basis, and you don't need to explain your faith, because its your belief. If I say that something is gravity, you can simply say, no that's god's will holding you down, and you can't prove or disprove it. Even if we come to an agreement that we can quantify mystery X at 9.80m/s^2 at the surface of the earth, you can still argue that it is only Mystery X at the surface of the earth in cases where the aether monster wants it to be, so you can bend any misconception that you want into a fact.
I'm sure this is going to be misquoted, so don't bother responding until you prove that your assumptions aren't mere beliefs in the unproven. The reason I think you are just messing around, is because you are very intentionally dodging the least critical, most logical questions that I've asked. They don't target you, and rather assume you are correct, and invite you onto the stage to share you knowledge. You won't begin by proving your statements because you don't have to prove your statements, because they are mere beliefs. If you at least want the A for effort, back up your claims with something consistent. If you want to prove that the aether exists because of an experiment that relies on gravity for the result, you are admitting that gravity exists. If you don't think gravity exists, you can't use the results of that experiment.
Science can't argue against an omnipotent force that can do anything it wants. Science can't convince religion, those that don't understand it, or those that purposely ignore it.
I acknowledge your right to your own reality. Your belief in a flat earth doesn't hurt anyone any more than someone's belief in a deity, cthulu, the flying spaghetti monster, or santa clause. Just know that not a single person will ever take you seriously if you can't understand the concept of backing up your claims, or blaming the jews for flattening earth or whatever it is you are doing.
