What if you could fly through the center of the earth?

I suspect the tourism income is going to outweigh anything else you might make, except if you happen to hit oil, gold and diamonds in the same hole.

first to become a millionaire pays 1 trill in UU.

and first to be a billionaire...

i guessed lol it could take a day to reach the centre (seriously inaccurate math ).

that reminds me that old joke about a miner who fell into a shaft. his mates calling him
"hey! are ya alive?!!"
"yeah!!"
"have ya broken anything?!!!"
"nope. i'm ok!!"
"so get the hell back up here!!!"
"i can't!!!"
"why?!!"
"cos i'm still falling!!!"

i think the person would pass by the centre then start back the way they came very soon after. you wouldnt build up enough momentum on the down trip to take you far once you are going against gravity. theres something called (i believe) a lagrange point (?) which is a place where gravity cancels itself out. for example the area between the earth and moon where their gravity is balenced. so if you put something there it stays where it is. maybe a planet has this, and being at the exact gravitational centre of the world you would just float there.

that's exactly what would happen. and there would be absolutely no stretching.

and here comes the hard part: now we have to get back to the surface.

Thing is, how large is the Lagrange point? Mathematically it is infinitely small, I suspect.

If your body is located around the Lagrange point, there will be a spot inside you with zero gravity, where all the outward pulling grav forces are cancelled. The rest of your body would experience pull to the outside, because the net force in any point except for the Lagrange point would be greater than zero in an outward direction, as the forces aren't cancelled anymore. Okay, I suspect that stretching is overdoing it, but still, your body would experienced forces that would try to pull it apart, even though their too small to do it.

Look at it this way: put a magnet exactly between two strong magnets with the same polarity. Both magnets would want to attract it's pole of opposite polarity to theirs, while both would want to push the pole with similar polarity away. What would happen? The magnet should stay in the same place, because the forces acting on it are equal. The same applies to the earth's gravitational field at the center, except that here you have a almost uniform field pulling from the center outward.
(btw - the reason for pulling outward: the mass of the earth is spread uniformly around you, rather than below you as is the case when standing on the surface)

aye. i know all that.. just the forces will be sorta rather on the small side. i don't even think ya'd be able to feel them (same as the difference in gravity between the poles and equator, nobody noticed to be havier on the poles)

[Tacet]

Yep, the forces would be small, probably too small to feel.

But hey, you'll still stretch, might just take some time! (I don't think much more than 10 mil years?)

[ƒëmmë ƒatalë]

mmm depends on if you are going N/S or E/W , earths spin and all that

[Deaths_Rider]

the spin would be almost nothing in the center just like gravity it's strongest at the surface although while you fall you may bounce off the walls a few times because of it
