Re: the earth is flat?
Well, strange as it is, we could be in a flat universe...and if one theorist is right, then the universe could be a hologram.
That would blow the flat earthers' minds to think their ideas could have some bizarre, oblique merit based on the esoteric but currently proposed theories.
That said, I agree with Mups and Purwell that all these cats, dogs, kids, and my own grace (or lack there of - running up hills, hiking up mountains, falling off of waves) leave me scratching my head at the flat earthers.
