Many subscribe to the “ice wall theory,” or the belief that the world is circumscribed by giant ice barriers, like the walls of a bowl, that then extend infinitely along a flat plane. Sargent envisions Earth as “a giant circular disc covered by a dome.” He likens the planet to a snow globe, similar to the one depicted in “The Truman Show,” a fictitious 1998 existential drama about an insurance salesman unknowingly living in an artificially constructed dome.

What then lies on the other side of the ice walls or beyond the glassy dome enclosing our world?

Flat Earthers don’t claim to know with certainty, instead paying lip service to “common sense” evidence they claim can be proved.
