It's funny how when I prove the Earth is round people ignore me. So now I shall provide you with a simple experiment that will prove the Earth is indeed round. The FAQ says the reason a ship in the ocean will eventually float away from sight isn't because the Earth is round, but it's an optical illusion, because you can't see that far. So here is an experiment to prove you wrong on this. Get a telescope, and get it perfectly set on the horizon. Now get one of your friends to get in a boat and start heading out, or watch someone else who's sailing out. Now, get the telescope in line with the boat, as I stated earlier. Now watch the boat with your eyes, as it starts to slowly move away from sight. Now you can't see it, but try looking in your telescope. Will you see the boat? If the Earth was flat, the telescope, which helps you see farther distances, would help you see the boat. If the Earth was round, however, it wouldn't help at all. Discuss.
