I still do not see why something in the sky would look like something under your feet. You make a lot of assumptions, lil big guy.
Oh, and YOU DON'T make a lot of assumptions about anything do you?
Flat earthers assume a great many things, NONE of which are backed up with verifiable and acknowledged facts.
It's your belief that the earth is enclosed by a huge reflective dome. Is this verified fact, or simply an assumption?
Flat earth fantasists also think that the earth as a whole is constantly accelerating through 'something' at 9.8 m/s, and this somehow accounts for the 'fiction' that you label gravity as. Is this verified fact or an assumption?
I could go on, but the list of assumptions that flat earth fantasists make is veeeeeeeeeeeeeery long.
First of all, I don't make assumptions. I can't speak for other FE'ers, but I can speak for myself. I theorize about the world we live in, like your own theoretical physicists do.
Secondly, I never said there is a dome over us. If another FE'er said it, then that is his own model, not mine. Don't put words in my mouth and try to get your facts straight.
And finally, Einstein is the one credited with coming up with the Equivalence Principle, not flat Earthers. He is the one who said that if you are accelerating at 9.8 m/s/s, then you would not be able to tell the difference between that and standing on the Earth. Personally, I think this was a slick way for him to proclaim that the Earth is flat without being ridiculed and losing his job, but that is just speculation.
So, out of the things you listed, none of them were assumptions. You really are bad at debate, are you not?
