The Flat Eart Scociety? http://theflatearthsociety.org

[quote="Raa"] For example, a glass of water prooves that the oceans are flat, but it is impossible to make a model of a ball with indentations filled with water all around it and then spin it and the water will stay in the indentations, no matter how powerfull a magnet you put in the ball. [/quote] no, this is incorrect. the surface of the glass of water has a miniscule curve to it, but it is there. the earth is 16000 km around, and a glass of water is 0.00005 km wide. (~1/20 of a meter) so thats 0.00005km/16000km = 0.000000003125. multiply that by 360 to get 0.000001125 degrees. this is correct, proving that not being able to tell if the surface of the water curves. water is not attracted to a magnet, magnetism is not gravity. Gravity is the miniscule attraction between neutrons(i think) and there are more neutrons in the earth to attract that water than the magnetic ball. now, if you took that same ball, made it a thousand times heavier and put it into space, then you could keep water in the indentations. but as long as there's a greater mass, thats what the water will fall to. And the sun warms the earth because it releases photons and other radiation, which is why we can see it and why it can sometimes affect telecommunications.

I'm afraid your comment on gravity being the attraction between neutrons is completely incorrect. For the most part, most stars have few to no neutrons, especially young stars, which are almost pure hydrogen. Only in very old stars do you start to see large amounts of neutrons appearing, but hydrogen atoms have no neutrons. If gravity was the attraction between neutrons, stars would fly apart.
