And I quote:
"Once again, picture in your mind a round world. Now imagine that there are two people on this world, one at each pole. For the person at the top of the world, (the North Pole), gravity is pulling him down, towards the South Pole. But for the person at the South Pole, shouldn't gravity pull him down as well? What keeps our person at the South Pole from falling completely off the face of the "globe"?"
Here is the first assumption I spotted: gravity only pulls directly down. Please, go make yourself a glass of hot chocolate. Excellent. Now that you are back, stir it well until there are some bubbles, a little less than half on the surface of the cup. Now put the blade of the spoon in the middle. Notice when you move near a bubble, it sticks. Now these bubbles are not adhesive, even when you put your hands in dish soap suds they eventually slip off. Now why would this happen? This is an example of the theory of gravity. Because the spoon has such a great gravitational field (greater mass) and the bubble has such a minute mass (gravitational field), the bubble is drawn to the spoon. Much like the enormity of the earth as the spoon, and us bubbles, drawn to the spoon because of it's great mass.
I quote again:
"Using the "round Earth" theory, setting an object on the earth would be like setting grains of sand on a beach ball. Certainly a few grains would stay - right around the top, the surface is nearly horizontal - but when you stray too far from the absolute top of the ball, the grains of sand start sliding off and falling onto the ground. The Earth, if round, should behave in exactly the same fashion."
This is assuming that the beach ball is on, let's say, an earth. Flat or round, this statement would work either way. Ok, so the sand slides off. But this is because it is attracted to the ground, and the beach ball is so light in comparison to the earth, the sand must therefore attract to the earth. But then what about the last statement:
"The Earth, if round, should behave in exactly the same fashion." This is assuming that the earth is sitting upon a surface greater mass than itself, let's say a giant alien table. Well if the earth was round, then yes, the sand would slide to the table, but not the earth. However, this is assuming that our earth is sitting upon a giant alien table, flat or round.
And yet another quote:
"Now imagine, if only for the sake of argument, that the person on top and the person on bottom can both manage to remain attracted to the ground "below" them. What would happen if the person on one side decided to visit the other? Since the man at the North Pole has a different idea of what is down and up (and in fact experiences an opposite pull from the Earth's gravity) than the person at the South Pole does, when the denizen of the frozen Arctic visits his Antarctic counterpart, they will experience gravitational pulls exactly opposite of each other! The human from the North Pole will "fall up", never returning to the ground, and will continue falling forever into the deep void of outer space!"
But clearly, this is assuming that the gravitational pull of a human is that of the flat earth. Let's say the earth is round- then the gravitational field is a sphere as well, for it must cover the earth. This gravitational field pulls to the very center of the earth, not in any other direction. This is another assumption of a great mass is beneath the earth (south pole in relation to the north ender). But then why would this only affect the north ender? And if there is, say a large hollow ball which surrounds the round earth, and it pulls a direct ray gravitational field. But then the great mass of the hollow ball would then explode from the gravitational "push" from every direction of the earth.
Please comment and discuss.
