The most convincing flat earth thread Ive seen in a while. Would like to know more about the glass dome theory , as well as hollow earth?
"glass dome theory"? It must be coincidence you asked! Here are my latest findings:
One tenant that the pre-copernican model (flat stationary earth) held was that there are multiple "crystal domes" covering the earth, seven of them to be exact.

There is some science to back this model, there is also an answer as to what is stopping model rockets when they reach extremely high altitudes. The atmosphere is in layers, some denser than others and due to variable temperature, pressure and the electric field it's not the simple case of a linear gradient. In the case of the upper layers, the gases are dense and in a state or phase of matter that can be described as a gaseous crystal (analogous to a liquid crystal). This advanced state can be exhibited by gases such as sulfur hexafluoride.

It should be noted that the final top layer (the firmament) is a solid nickel-iron damascus type steel with an reflective golden oxide (crystal) coating.
As for "hollow earth" the pre-copernican model describes a place below the earth called "sheol",

I can't say much more at this point in time.

Perhaps the following video from Fossilien der Götter can help you understand that you're not living where you think you are...

Here's one from the 80's!
