Curvature of the horizon is an optical illusion caused by the fact that the Mk 1 eyeball is itself spherical. Therefore it stands to reason that you will see any sufficiently long straight edge as a curve. I mean, all the maps I've ever seen have straight edges so the horizon must be straight . . . innit!
