there is no edge, we live in a realm of sorts, with a floor and a ceiling. The stars and moon are nothing more than lights on the firmament. Space is fake, there is no star wars type space, that is all a magic show.
Those questions you have are very typical, you go to google and search you will get sites that talk about a cat, and gravity, and love to say FEs think we live on a disk in space, like i said there is no space. Space is absolutely ridiculous.
that is not what FEs think, like i said no edge, no disk in space, that is strawman stuff.
We are not allowed to explore farther south or out past the 60th parallel south, it is a law in the Antarctic Treaty signed by all the nations, you can go on a cruise ship, take a zodiak and step on a peninsula and get a picture of a penguin, but no one can independently explore Antartica, if we were able to, then immediately it would become apparent that the earth is flat and we are not on a ball.
We live in a big lake, the continents are islands and the shoreline around us is Antarctica. The North Pole is in the middle and it is magnetic, all compasses point north even in the south or out beyond the equator, they still point north.
What is beyond the shoreline is up to debate, I think we are on endless type plain and there are other suns very close with worlds just like ours but maybe 20 thousand miles beyond the shoreline of Antarctica.
Our sun is very close and it moves around and over us once a day. It might be 50 miles across, 250k feet up. Here is link to a kind of the going map, but FEs dont really know, it is all not known.
Hard to link pictures anymore
And here is a another picture that could be what we live in, our earth is in the middle, and then there is the ice wall per se, then another realm close by.
