If cross-sectioning 2d & 3d objs with a plane, you get plane-limited reflexions. Why not so with a 4d obj? Is a 3d obj cross-sectioning it?

Yes!. Indeed, a line (say the real line R) cross-section the circle, a plane (R^2) cross-section the sphere, so R^3 cross-section the gloom!

Gif don't help. Imagine how you submerge circle/sphere. Where circle/sphere's points intersect the plane you get line/circle.

My brain aches. Can we set up a movement that insists the Earth is actually 4D? I’m trying to imagine what the turtles would look like.
