On a more serious note:
* Sun and Moon. Spherical earth theories suggest that the sun and moon should appear above the horizon – from our perspective – at different times in different places, thus the need for time zones. Flat earth theories suggest that they should be visible at the same time everywhere, and most have the sun circling above the earth, so it should be day all the time everywhere, though some suggest extreme atmospheric refraction.
* Visible stars. Spherical-earth theories suggest that certain stars should be below the horizon from certain latitudes. For example, Polaris is below the horizon for the southern hemisphere, while the Magellenic coulds are below the horizon for most of the northern hemisphere. Flat-earth theories suggest that the same stars should be visible regardless, though some suggest extreme atmospheric refraction.
* Foucault’s pendulum. Spherical-earth theories suggest that they should depend on the latitude. Flat-earth theories suggest that the timing and direction of Foucault’s pendulum should be the same at all latitudes.
* “Great Ice Barrier.” Since people can and do cross the Pacific, flat earth theories tend to put the arctic in the middle, and the antarctic on the edge of their world, while insisting both antarctic exploration and space exploration have been hoaxes.
If ‘Time’ was a massively big oval, instead of a straight line, would we notice the difference?
Nietzsche said “What, if some day or night a demon were to steal after you into your loneliest loneliness and say to you: ‘This life as you now live it and have lived it, you will have to live once more and innumerable times more’ … Would you not throw yourself down and gnash your teeth and curse the demon who spoke thus? Or have you once experienced a tremendous moment when you would have answered him: ‘You are a god and never have I heard anything more divine.”
Stop! Stop! You’re blowing my mind!
You think that blew your mind? On the Simpsons, didn’t Mr. Burns say something about not killing an animal that can perform an amusing trick?: https://www.youtube.com/watch?v=XfPBfMGLf9Q
Ha! More useful than a cat and, unlike cats, it probably doesn’t have any ambitions to take over the world.

I like the hollow earth theory. As everyone knows, give a box to a cat, and he crawls in immediately. It explains were cats go when they disappear.
