Very disappointed. I was directed here by a person who said people here could prove the world to be flat. However, what I have seen is claims without factual backing, and when factual backing is requested, the answer is "That is unknown" or something similar.
Let's assume the world is flat, there is ice surrounding is, and everybody who believes the earth to be round is in on some conspiracy.
Why has nobody hopped into a plane, taken off from Australia and flown towards this ice wall and recorded their results? If the earth is flat, a point will come when they will see an edge, and can return and confirm. They don't need to fall over the edge and perish into space. They just need to see the edge! If they continue to fly and never ever ever find anything, then they can conclude the earth is indeed round.
I've seen two other arguments for this. 1, the government will make sure you do not find out that the world is flat. Prove it to me. You cannot. All you can do is make claims, because until one of you hops into a plane and tries it, you will have no idea.
The second is that we do not have the ability to transport ourselves onto this sheet of ice. False. We currently have scientists living on the "South Pole" who continually fly in and out, and who sometimes make journeys months on end deep into the poles on dog sled. We can get there. If you believe we cannot, prove it.
Thanks.
