    "Earth is flat" thread

    I have another question about the earth related to "earth is flat".
    Look at the following picture:



    You see the water in a round shape so why does not water fall into the space if the earth is round? Should not it fall?
    Baaaaaaaaah

    Well if earth is flat, then you had to build some kind of walls around it to hold the water inside.
    Use
    writing software in C++ is like driving rivets into steel beam with a toothpick.
    writing haskell makes your life easier:
    reverse (p (6*9)) where p x|x==0=""|True=chr (48+z): p y where (y,z)=divMod x 13

    The water IS Falling into Space!
    So's the earth, but the earth is faster!

    BTW: I SEE SIGNS OF ALIEN VISITATION!

    Just How big ARE those Letter Shaped Structures!

    I think that is the earth's gravity

    But if you look at the earth generally, the water should me falling in the space!

    Simply!

    If you spill some water on football then the water falls on the ground. Right? The same idea should be with the earth!

    But the football doesnt have gravity!!! like earth does!

    Try spinning the football then drop some water on it?
    Does it stay on there longer then it does if it aint spinning?
    The reason it doesnt stay on the footie is because of earths gravity.

    If the earth had some huge planet (take the size of the football, take how many times larger the earth is, the planet would this many times larger than the earth) so close to it, the water would fall off it (toward the huge planet) just as easily as the water fell off the football

    yep,

    take the footy into space make sure there's no planets or anything around spin it then drop some water near it the water will be drawn to the footy.
    Now get a beachball spin that as well right next to the footy the water will be drawn off of the footy towards the beachball.

    You might even be able to get the football to orbit the beach ball


    I'm assuming the beach ball has more mass. I hope the assumption is correct..

    Well if it's spinning, the water would be pulled out by centrifugal force (once the water gets to the football and settles down on it and spins with it) and pulled in by the gravity of the ball. So I suppose that if it's spinning fast enough, the water would fly off. I never took any physics classes, so I may be wrong..

    But, yeah, as far as the watter getting attracted to the ball is concerned, the fact that it's spinning does not matter.

    In addition, the water would be drawn towards the football as, despite the fact that the beach ball is bigger it has a significantly lower mass.
    Okay, suppose the beach ball is filled with water or some other heavy liquid.

    Smile Electromagnetism

    If there was no such, the water would fall straight trough the football

    SD:

    I was assuming that the beach ball was heavier and bigger than the footy!

    Can you explain this? Like I said, I never took any physics classes..
