I would just like to see the subject of the dome explained, too....by FE's.
(Am not an FE'er but...)
I think you have your explanation. There are AT LEAST three or four different Flat Earth groups - some base their beliefs on religious grounds - they tend to believe in the dome because the bible says it exists. Others are of the "zetetic" approach which basically says that unless you can do the experiment for yourself - you can deny it's validity.
This group (tfes.org) has a Wiki that does not claim that there is a dome.
So continuing to ask them about the dome isn't going to get you anywhere.
For the purposes of discussions here - there is no dome. There are a couple of the religious-FE'ers here who argue as much with the other FE'ers as you and I might - but since they have ZERO proof of the dome (other than literalist bible claims) - they may safely be ignored.
My first attempt on this website was on the subject of how amateur radio operators had done "Moon Bounce" and had come up with an estimate of the distance from the earth to the moon. I think the details were fairly well covered in detail.
Arguments of the form "
Some other people did this experiment and it proves X, Y and Z" are not well accepted here. A common response will be "
Did you do that experiment yourself?" - and of course, you didn't. Hence either you're mistaken - or the people who claimed to have done the experiment are a part of "The Great Conspiracy" - and any such evidence will simply be dismissed. So unless you actually did this experiment - you're out on a limb here.
Again - if you want to be able to discuss things here - you need arguments that involve only the evidence of our own eyes - preferably with a minimum of fancy equipment.
It's ridiculously easy to disprove FET using nothing more than your own eyes. A trip to Australia and watching how the stars move. Searching online for flights from Australia to South America and South Africa. Going to the equator and watching how moon is rotated 90 degrees compared to how it looks in the northern USA or Europe.
These are all ridiculously easy experiments - and not one of them produces results that FET can explain.
So - let's figure out what the FE'ers believe about those phenomena...every single time I've tried, I get silence.
