Answer 1

Gravity points toward the center of the Earth. Now if somebody was standing at the north pole and looked down through a transparent planet to somebody standing at the south pole, that person would be upside down from their perspective.

There’s actually a description at the end of Dante’s Inferno where Dante looks and sees Satan upside down and asks why and is told that since down from anyone’s perspective is towards the center of the earth and Hell is on the opposite side of the Earth then someone on the other side of the Earth would be upside down from his perspective. I thought this was fascinating because Dante’s work came long before anyone sailed all the way around the Earth.
