1) The ice wall would have to be like 10 miles high for this to be possible. Someboody would have seen the damn thing by now. We would have pictures of it, real pictures, not those phoney baloney photoshoppy things you shrills try to pass off as pcitures. If it were this high you probably could see it from the tip of South America. In fact if the Earth is flat like you say you wouldn't have to be anywhere near it.
Can you see Mount Everest from Alaska? Why should this be any different? If explanation 1 is true, then the "ice wall" is simply a very long, very tall mountain range which is potentially several thousand miles south of the coast of Antarctica.
2) "Celestial Dome?" You mean like the Biblical "frimament?" Where the hell did this come from? So this theory says the cosmos is kinda like a gigantic snow globe, sitting on God's curiosity shelf? Are you fraking serious?
This is one possible explanation, yes.
3) The Earth just stretches off into infinity? Just forever and ever and ever, yet it's still accelrating upwards, and there's still a gigantic snow-globe dome over it? Does any of this shit make sense to anyone?
If explanation 3 is true, there may not be a dome. But why shouldn't it stretch off to infinity?
Your theories sound like rubbish.
Yeah, well, I wasn't the one who made a post about sky crappers containing an obviously distorted photograph showing curvature of horizon which simply is not visible at that height.
I think it would be impossible for there to be an ice wall structurally stable at that height.
It's essentially a mountain range, and as far as I know, mountains are pretty structurally stable, but if you want, you could try to move one and if you succeed, I'll reconsider.
A celestial dome assumes the earth is like the bottom of a crystal ball, right? Because if that is true, I wonder why airplane flights from South America to Australia haven't crashed into it yet. Or is it so high that it holds the stars up? If that is true, then, once again, I doubt its structural integrity.
Spheres and domes are extremely structurally sound, which is why spheres appear so commonly in nature, and why domes appear so commonly in architecture. Nobody has crashed into it because it would have to be very high up over most of the surface of the planet, and would only meet the ground well south of the coast of Antarctica, where nobody ever goes. As for the strength, who knows what material it might be made of? I'm not claiming that there is a gigantic glass dome which supports the sun.
