An Open Letter to the Flat Earth Society

Do you sometimes use GPS To navigate your flat world? Did you ever wonder how all those satellites Get around to the underside? Do you use a flush toilet Or a siphon? See, fluids can sometimes run uphill. Your “the Amazon River is flat” theory Fails to hold water. Did you ever consider an Antarctic cruise? Did you ever want to sail around the South Pole? You could look out for the ice-wall That you think holds the oceans in. Do you recognize a metaphor? When the Bible talks about the “Four corners of the Earth”, It’s an idiom for distant lands, Or is your world-view ‘square’? Every other celestial body we can see is round. Why should the Earth be so different? Phases of the Moon, Pictures of Earth taken by astronauts, The “celestial spheres” really are spherical. If you need a book to tell you what is real, Try a physics book. If you need a tool to discern what is right, Try logic or experiment. Try to see beyond the horizon. If your world is really constricted To what you can see from your limited view, Then, perhaps, start walking.
