I am educated enough to actually understand the word "perspectives" without the need to look it up. And if I did, there would be nothing about the moon in any dictionary definition.

Anyway I didn't ask for a cryptic hint. I just want your basic, straightforward explanation.

If you have one.

My straightforward explanation is that due to the earth being a globe, "up" in the UK is a different direction to "up" in Australia as gravity pulls us in towards the centre of the earth. So, "up" is a subjective experience depending where on the globe I am.

What's yours?

Provide the pictures of curvature, I can guarantee a curve in the glass. No curvature in this one

Nah, the flatearthsocienty have doctored that one. CGIed it. I don't believe that picture is real.

Would that apply is Australia was on the bottom-side of a flat Earth of significant mass and the UK on the top-side?

The difficulty in the OP's assertion seems to me to come from what happens around the edges of the flat Earth?

If you can't tell the difference between land and clouds then your gormcloptitude is clearly limitless.
