    A random science type question

    Was thinking about this in the shower too =P...well neway, i thought of how Earth was round and stuff..and i thought, wat if there was a hole in the north pole that went straight down to the south pole? and if there was, if u dropped down into the hole in the north pole, would u keep falling until ur falling upside down? Like when u pop out of the south pole, would u be flying into the sky? This is such a confusing question...well neway, lets say that gravity played an important role, lets say u fall into a hole in the north pole, now the earths gravitational pull will make u accelerate down towards the center and by the time u reach the middle, the gravitational pull is unable to control ur movement at the current time, so u keep falling and falling but then ur actually rising and rising cuz when u get to the south part of earth, ur not falling, but rather rising, yes i think it seems pretty connfusing, though this situation is mostlikely impossible due to the inner part of the earth being super hot (but lets assume that heat doesnt play a role in this), so neway, what do u think? Would u keep falling down from the north pole until u reach the southern side of the equater and start rising? Will u fly out of the south pole like a bullet and completely stream into the sky and out of earths gravitational field and die in space? For me this is such a mind boggling question

    Nope, you wouldn't fall out of the south pole. Infact, you'd never make it out of said hole. Terminal velocity is not enough to escape the earth's gravity, which a good part of can be attributed to the earth's condensed, superheavy, radioactive core, if I'm not mistaken. So, you would fall, and then you would pass earth's center of gravity and immediately start to be pulled in the opposite direction, never reaching the south pole at all.

    I agree. You would never reach it, but I feel, that's there's no way you could make it through to the other end, due to the core. You would be vaporized, as you went down, then I guess, you would just burn. Ehhhh, that's a really crazy question O_o

    Actually, that raises a very good question. Just where would you stop? Assuming that the exact centre of earth was taken out, where would the planets centre of gravity be?

    ArGH!!! Confused @.@

    Hmmm... He's not technically human, so it wouldn't really be like cannibalism...

    You probably wouldn't make it to ground level of the south pole, as you'll lose a lot momentum on the way down, due to air drag. Also, the center of gravity of the earth system isn't exactly at the center of the earth's core. You have to take into account the gravity effect of the moon (which is constantly moving) as well...

    If that center is removed (or taken out like you said) then you wouldnt even drop, the earth's core is the responsible for the gravity, so without it there will be no gravity and therefore nothing can drop since there is no force pulling you down.

    For the thread starter, lets just think that there was a hole like that, and that the earth core wasn't supperheat so something can drop in without being incinerated. The core is pulling things inwards in any direction, so if something drops in from any of the poles it will stop at the middle, and will not go out the opposite way.

    yeah, youd just end up being dust by the time anything happened......
