This is where the telescope come in. If we have charted the movements of all the planets we know that they are not orbiting the Earth but rather the sun. If we look at the movement of the Earth, in relation to the other planets, then we know we are moving around the Sun.crudus said:That doesn't so much prove the Earth is round so much as big[footnote]If you wanted to prove the Earth was round just look at sea as a ship sails towards you. You will always see the ships sails before the ship itself[/footnote]. Although I never said it was.Gilhelmi said:We first must prove the Earth is round we do this by showing the curvature of the Earth. Look out to the horizon as far as you can, the walk there. You can see the next horizon, continue on until you get back to your original point on Earth (I assume you have a boat).crudus said:Ok, lets see how good you are.
Everything revolves around the Earth while the Earth remains motionless. You can prove the latter just by watching the heavens; they move as we stay put. The former is easily proven by a simple experiment. Imagine driving in a convertible. You throw a ball up. The ball will fly backwards. If the Earth was moving then you would fly back in the same fashion every time you jumped.
By using a telescope we can chart the movements of the planets around the Solar System. Using this we see that the Sun is stationary (not really but that is another discussion) and that all the planets, including Earth, revolve around the Sun. The Moon is the only exemption to revolve around the Earth.
How can the sun be stationary? If you drill a hole in a wall and mark where the sun hits at a certain time of day, the mark will be different for each day.
(Now I know how Galileo felt, lol)
Impossible task. I can not prove that joke came from a thinking being. LOLProve you are thinkingThe_root_of_all_evil said:So you're a mass-debater?

Ok:- I think, therefore I am.
