the centre of the earth gravity conundrum

  1. If there was a random hollow space in the earth,

    You would be crushed. BUT not by the weight on top of you.

    In a hollow space in the middle of the earth, the centre of gravity surely doesn't apply. The rock around you has gravity, so the centre of gravity is all around you, pulling you in all directions.

    The gravity above you wull pull your feet (and your entire body)in the direction of your head,

    The gravity below you will pull your head (and your entire body) towards your feet,

    and the same for left/ right, front/ back.

    so you will be crushed, by being pulled in every direction simultaneously.

    The reason this is hypothetical, is that for there to be a hollow space, it would have to resist the pressure around it. Which is why you would be crushed. Because this space wouldn't exist and you would be in extremely dense + hot rock.

  2. I don't know but that sounds feasible.
    I LOL'd at those pics.
     
  3. Thanks to whoever put this in the right thread.
     
  4. Judging from that picture, it appears Arnold Schwarzenegger was the Big Bang.
     
  5. The purpose of time and space was so that Arnold could exist.
     
  6. If you don't count the fact that it'd be extremely hot, you wouldn't be crushed. If gravity was that strong it would crush you to the ground on the surface, If you were in the middle I'd think you'd simply float there due to equal pull all around you, but it's not strong enough to rip you in all directions.
     

  7. ooo I like this better.

    I wouldn't want to have Arnold the last thing on my mind as I am pulled in all directions watching my body rip apart.

    :p
     
  8. it wouldn't do crush you, it would do quite the opposite. Although i'm not sure if the force would be strong enough to rip you apart
     
  9. I agree with float inside being pulled in all directions, given the space inside is large enough. Interesting idea.
     
  10. BUT... If the earth were hollow, and all there was was the crust, which is miles deep still, the gravity would be much less since the Earth's mass is greatly decreased. :cool:
     
  11. I'm only suggesting the hole is big enough to fit a person, like room sized.

    The scale on the diagram is slightly off.
