please help if u can?

Question

if we dug a tunnel down through the centre of the earth and came up in australia, and i jumped in the hole would i fall all the way through or stop in the middle,cos on the otherside i cant fall up, what do u think

Answer 1

I would think that you would spiral toward Australia and then back toward us with the mid point at the center of earth's mass, each time not going as far as before .

The reason that you would basically oscillate like that, is that the force of gravity increases the closer the centers of mass are to each other (the closer you got to the center of the earth) and so you would be accelerating the entire way till you got there and you would continue going because there would be no force acting on you to decelerate you. As you start going away from the center toward the land down under, the force of gravity would act against your current velocity, till they cancel each other out and you start to fall toward the center of the earth this time the other way. The reason that you would not quite make it out the other side of the hole is wind resistance and other very small forces would be affecting you.

Assuming I'm right, you would eventually end up rotating in 3-dimensions around your stomach (or where ever your center of mass is) at the center of the earth.

Answer 2

you cant dig a hole through the centre of the earth its impossible its too hot and too long and no you cant fall up but since youre on the opposite side of the earth it would be like falling down

Answer 3

Okay, you would go past the center due to the velocity you generated from your descent, then you would go so far up the other side, then come back down, this would repeat (like a rubber ball bouncing) with the distance past the center decreasing each time until you ended up stopped in the center.

Answer 4

First of all if you digged a hole through the earth you die through the center because of the magma. second thats a stupid question. but thanx for the two points. the answer shows how smart i am. heheheheheehehehehehehehehehe

Answer 5

You woul fall right back to where you started actually not fall but be sucked by the vaccum of the equator. Try it me and cousins do it every spring.

Answer 6

You would be crushed to the size of a pin head and fried to a crisp then be trapped in that state in the middle for ever.

don't jump!!

Answer 7

as you go down into the earth core it gets HOT really hot and you would be zapped before you know it....bet bet is to book a flight wi an australian air line if you really want to go there :-) Wouldya send me a postcrd wen you get there tho????? ta!!

Answer 8

i think you would never make it to the other side because it is super hot in the core of the earth

Answer 9

You would stop in the middle.

Answer 10

I can't wait to ask this question to my boys the next time we get stoned.
