Just a thought to leave NS on a friday night.

Let us suppose there were a hole straight through the earth. (IE here central america to wherever it would be on the other side) Then let us suppose there isnt any soft of molten lava center, and all that jazz.

Now what would happen if you fell through that hole, presumably to the other side. At what point would you begin to "fall" up? (obviously the center of the earth, i think?) but what would happen? Also would you be able to tell?? would you fall feet first and then fall up feet first? would you get a head rush? what???

make it happen NS!
 
can i add to the craziness? what about taking the earths orbit into account. would you begin to rotate as well? someone answer these questions
 
daamn, thats a really good question. i think you would pass out and/or die from the speed at which you are falling.

my other thought is that while you are falling down towards the center of earth, gravity is pulling you down. but when you go through the middle then gravity would be pushing you down, therefore slowing you down and you would eventually just be stuck in a big ass hole because you wouldnt have enough speed to make it out the other side

You would accelerate until you got to the center of earth, then you would gradually begin to slow down.

If there is no air resistance, you'd come out on the other side of the world at the exact speed you feel in at (0 m/s).

With air resistance, you'd stop just before getting to the other side, and fall back toward the center. You'd keep falling past the center back and forth, gradually falling less far each time until you eventually stop in the center of the earth.
 
To that, no. If anything, you would stop rotations while the earth would continue to but it would make such a little difference that it wouldn't matter.

And to the OP's question, it has been a while since I took a physics class but if you slowed your fall down enough to be floating when you hit the center(parachute or something along those lines), I would like to think that you would stay suspended DIRECTLY at the center of the earth since there is no gravity pulling you down.

Granted this is probably an irrelevant since I am stupid, but I gave it a try.
 
In 1966, mathematician Paul Cooper theorized that the fastest, most efficient way to travel across continents would be to bore a straight hollow tube directly through the Earth, connecting a set of antipodes, evacuate it (remove the air), and then just fall through. The first half of the journey consists of free-fall acceleration, while the second half consists of an exactly equal deceleration. The time for such a journey works out to be 42 minutes. Remarkably, even if the tube does not pass through the exact center of the Earth, the time for a journey powered entirely by gravity always works out to be 42 minutes, as long as the tube remains friction-free, as while gravity's force would be lessened, so would the distance traveled at an equal rate.[5][6] The same idea was proposed by Lewis Carroll in Sylvie and Bruno, volume 2, chapter 7, without calculation.

im almost positive that if any of that happened, you would reach the middle and stop there, because everyone knows that dinosaurs did not infact go extinct, but gradually dug themselves deeper into the earth until they reached the center, then when you met them, you would realize that none of them look like dinosaurs that your use to seeing drawn, but more like all am exact replica of john stamos so, when you guys were stuck in the middle you would end up partying the fuck out of yourselves and end up committing suicide because you were so stoned
 
there you go. gravity pulls everything on earth into the centre. once you are there you wouldnt fall anymore and would get stuck there.
 
Here's what would happen.

Newton's law of universal gravitation states that the force of gravity is inversely proportional to the square of the distance between the centre of masses of the two objects, in this case, you and the earth.

Therefore, as you approached the centre of the earth, the distance between you and the earth would decrease, so gravity would decrease.

At the centre of the earth, gravitational force would be zero. But if there is no air resistance, you will shoot straight past the centre point, and out the other side. As you increase the distance between you and the centre of the earth in the opposite direction, you would decelerate, and be pulled back towards the centre of the earth in the opposite direction. The process repeats.

So, if there is no air resistance, and no gravitational force exerted by any body other than the earth, you would oscillate about the centre of the earth for eternity.
 
you'd be going fast enough that you would "fall" up a bit, but then the gravity would pull you back to the center of the earth..and you'd be going back and forth from "falling" up and down at an exponentially decaying rate.
 
You would accelerate at 9.8 ish m/sec/sec until you got the the middle and then start decelerating at the same rate until you got to the hole on the other side provided the hole on the other side was not further from the center than the hole you dropped in. This would all take 42 minutes according to the history channel.
 
imagine trying to make a pile of dirt. you keep piling dirt on the top and some if it rolls down the side, so you end up with a cone shape pile. when you do the opposite and dig a hole, the dirt spills into the sides. if you go to a construction site and look at an excavation, the steepest slope you'll ever see is a 1:1 or 45º, if the material is clay (this is an iso standard, you can actually dig clay much steeper), but with other materials like sand the angle is much smaller since there is less internal friction. this also implies that if you need to remove more earth for the same size excavation if you have a material like sand, compared to a more favorable material (clay being the most favorable you can find)
 
Well currently scientists suspect that the core of the planet is solid anyway so you would just hit it and die.
Also I'm surprised no one posted that sinkhole.
 
Isn't that shit the stuff that snipers have to worry about on shots from over a mile and a half away?
 
Are you implying that this hole is impossible because its slope would have to be 1:1? If thats what youre saying than...A.) This would only be a problem if the hole were dug in the desert with no modern equipmentB.) It would cease to be an issue one the mantle was reachedC.) Its a hypothetical situation. OP isnt asking if it can happen but rather what would happen.
 
I remember seeing a show about the longest CONFIRMED sniper shots and there was one with this Canadian sniper that took out 3 Iraqis who were behind a wall with one shot from 3 miles away. Was fucking insane.
 
i heard he killed the one guy in the truck turret and knocked a paper bag out of the second, and then corrected and killed the second.

but i heard that record was beaten a month ago by a british sniper. you can look it up.
