mozo Posted June 1, 2006 Report Share Posted June 1, 2006 Gawd, don't twist my melon like that.I dunno, but when you do, get some photos of the earth's core - sounds immense (a real hot-spot ). Apparently there's a solid inner core of pure iron the size of the Moon, and an outer liquid core rich in iron the size of Mars. Mental innit - S****horpe must be down there.

Dollymarie Posted June 2, 2006 Report Share Posted June 2, 2006 Well you could look at it two ways, 1. You'd melt when you got to the molten bit in the middle and not make it.2. You'd have built up so much speed that by the time you fell out in Australia that you'd ending catapulting off into space. ...........or would you, because of the earths rotation, maybe by the time you made it through Australia would be on the "up" side by then and youd just get splatted by your own weight.God I could be here all day, my geography and science teachers would be so proud.

RED4LIFE Posted June 2, 2006 Report Share Posted June 2, 2006 I think you would stop at the centre of the earth considering gravity has to be central to the earths core.Oh its far too early to be thinking about this sort of thing. Link to comment Share on other sites More sharing options...

dagest Posted June 2, 2006 Report Share Posted June 2, 2006 I suppose the gravitational pull of the moon and all that other scientific gubbins would come into play.I've worked out the following mathematical fomula which should help work this out:10/3+41288558 - 3 + 2 100$ 2006[-12}-1 = And there's your answer.It was quite easy after a little bit of thought.

gazareth Posted June 2, 2006 Report Share Posted June 2, 2006 I don't think you'd stop completely at the middle. Assuming you could pass straight through the middle, you would build up enough speed to overcome the gravitational pull briefly, and would probably slingshot onto the "other side" of the tunnel. Eventually the gravitational pull would bring you back in and throw you back and forth until you came to rest in the centre. Link to comment Share on other sites More sharing options...

Guest DrFaustus Posted June 2, 2006 Report Share Posted June 2, 2006 ... through the earth, from London to Sydney, and I jumped in it from London - at what point would I stop falling?At the M25....there's always hold ups. Link to comment Share on other sites More sharing options...
gazareth Posted June 2, 2006 Report Share Posted June 2, 2006 Would I not build up enough speed to shoot out in Sydney and fly off into space - thus rendering the gravitational force of earth useless?No, because once you'd gone past the central point, gravity would be acting in the opposite direction and would begin to slow you down.

gazareth Posted June 2, 2006 Report Share Posted June 2, 2006 Try to think of it like a bungee rope tethered to the central point of the world - you start in London with the rope at full stretch and it loosens as you go. You will continue to fall once you reach the pivot but once the rope is fully stretched again you'll start to fall back... Link to comment Share on other sites More sharing options...
dagest Posted June 2, 2006 Report Share Posted June 2, 2006 Presumably, you would eventually settle somewhere in the middle (after all this back and forth), but would you be pulled in half at any point if the gravitational pull at each end became relatively equal? Perhaps it would feel like you were on the rack? Link to comment Share on other sites More sharing options...
Nibor Posted June 2, 2006 Report Share Posted June 2, 2006 The most likely outcome is that you'd end up being a sticky red stain on the side a few hundred metres down the hole. Link to comment Share on other sites More sharing options...

gazareth Posted June 2, 2006 Report Share Posted June 2, 2006 Gah it's all way more complicated than I thought due to centrifugal forces caused by the rotation of the earth and such Don't dig the hole, if you wanna go to Sydney hop on a plane instead Gazareth, you are the fountain of knowledge and I love you, but - is the gravatational pull equal either side, thus meaning I would settle in the middle?As far as I can tell, the pull varies depending on where you are on the earth. Acceleration due to gravity at sea level on the Earth's surface is 9.80665 m/s² (metres per second per second). This value increases are you get closer to the centre of the earth.More on acceleration due to gravity:http://en.wikipedia.org/wiki/Gravitational_pull Link to comment Share on other sites More sharing options...
Nibor Posted June 2, 2006 Report Share Posted June 2, 2006 The bungee analogy is a bit off, it only works if the bungee gets dramatically shorter every time - because you'd hit terminal velocity quite early into your fall. Link to comment Share on other sites More sharing options...

CiderHider Posted June 2, 2006 Report Share Posted June 2, 2006 What if the Earth was Do-nut shaped? And the hole in the middle was massive? (no core & magma) the edges into the hole were at a right angle (no gradule curve)You would fall off a 25'000 mile cliff? Link to comment Share on other sites More sharing options...
