If I dug a hole straight down all the way to the other side of the earth would I fall down the sky?

Question

Some one explain how this works

Answer 1

Darlin, you'd be cooked like a well-done roast beef before you even got to the center. Remember the core is hot, boiling rock. So you'd definitely have other things to worry about than falling "down the sky."

Answer 2

Alright. We'll throw out internal temps, liquid magma, etc, and assume that the Earth is a solid sphere that you could conceivably drill all the way through. Now, the short answer is, no, you wouldn't fall "down" to the sky. Your body stays "on" the Earth due to gravity. And when most people think of gravity, they tend to only apply it to the planet. Not to themselves. The truth is, that you exert a force against the Earth, just on a weaker scale. As you dug towards the center of the Earth, you'd start feeling "lighter" because more of the Earth's mass (the raw material) would be shifting its location to you. If you were a 1/4 of the way to the center of the Earth, you'd have 1/8 less gravitational pull against you "straight down" because an 1/8 of the diameter would be "above" you. At the center of the Earth, you'd feel "weightless" since the Earth would uniformally be pulling you in each direction. It'd be "in limbo" You wouldn't be ripped apart. You just wouldn't "weigh anything." Then, as you continued your tunnel to the other side, you'd gradually feel that you were regaining your weight. Once you broke through, you'd weigh the same on the other side as you do here. Now, if you were to be "shot through" the tunnel that you've dug, depending on your initial acceleration (which would increase by 9.8 meters per second squared and top out at a certain terminal velocity) you could possibly shoot out the other side, but it's unlikely that you'd be able to escape the Earth's gravitational pull enough to reach an escape velocity, even if you were at the Equator.

Answer 3

I actually worked this out in a calc assignment last term.

You'd oscillate in harmonic motion - you'd fall all the way through the earth, get to the other side, then fall back through the hole.

Assuming you could survive the intense heat and pressure as you got towards the middle, which of course you could not.

Answer 4

if u dug stright through the earth ud either die from exaustion or burn up around the mantle. but lets say thats not a possibility then u would be cushed by earth upon passing the halfway point.

Answer 5

wow. never even thought about it that way.....
good one. i think (even if you did get through the core, and the magma, without killing your self in the process..) that it would be like shanding on the ground normally because the gravity will be pulling you. that is why the blood would not rush to your head i sbecause of the gravity. but if you are on a monky bar and you are upside down then the blood would rush to your head because the gravity would be pulling it....
i think...
i am confuzzled!(confused)

Answer 6

lol no. if u ever did manage to get to the centre of the earth u would cause an singular event horizon. the true centre has no gravity or time as defined by E=MC2

Answer 7

You would get stuck in the middle - and if the immense gravity didnt squish you into a pulp, the heat would have toasted you anyway

Answer 8

Hell would freeze-Over before You got that far!! The Sky is above us, Not below us! You'd probably see Hell First!!

Answer 9

no u would fall down to australia,but you would die coz it is so hot in the middle of ther esarth

Answer 10

Then you can take the dirt and fill the hole that is in your head..
