what’s past the ice wall?

do we exist on a board with neighboring similar earths?

is the earth just part of a bigger field of bio-domes?

so many questions

Because of the Earth's curvature and the way the planet is oriented in space. It all comes down to your vantage point on the globe.

Essentially, the Earth itself acts as a giant obstacle, blocking your line of sight to the northern part of the sky when you're in the southern half of the globe.

Heh... Give me numbers, distances and angles. As someone who is well versed in math, I say this is just gibberish.

You can easily calculate what's visible and what's not on a flat earth, why hide the numbers? Give me hard numbers and I'll consider.
