If you dug a hole straight through the centre of the earth would you come out feet first on the other side?

well if you forgot about the fact that the heat (the core is molten rock and iron) along with the pressure (the closer you get to the center of the earth the more pressure there is) would easily kill you no you would fall and get stuck in the center because a person can only gain so much momentum before they begin the slow down again and you wouldn't have enough to get out the other side

Center of the earth, since it hasn't been done before

If you define up as the direction towards the sky, and down as the direction a ball will fall when dropped, then there is no difference when you stand on the north pole, south pole or anywhere in between.\n\nThe Earth is spherical so Earth's gravity pulls in the same relative direction no matter where you are, down towards the center of the planet, so that makes down always towards your feet.\n\nAnd also since the Earth is spherical the sky will always be above your head, up. \n\nSo there is no difference in upside down or right-side up based on where you are on the Earth.

Assuming you somehow manage to get the ladder pass the centre and out the other side; could you throw a rope ladder 6,378km towards space?\n\nThen the next hurdle; have you ever tried to walk feet-first up a ladder? Because that's what you'll be doing once you've got past the centre of the Earth.

Besides the intense heat and pressure, gravity would be the major force acting on you (say if we lived in a world with no air resistance.) As you would get closer to the center of the earth you speed would be increasing, but once you start pulling away from the center you speed would be slowing down due to gravity pulling on you from the opposite direction. At the opposite side of the earth you find yourself to come to a standstill for a brief second until you get pulled back inward toward the center and emerge on the same side of the earth in which you started. You would be stuck in this cycle going from either side of the earth until someone threw you a rope and are able to pull yourself to the surface.

Earth is 12,742 kilometers (7,900 miles) in diameter. That's how far you would have to tunnel to dig to the other side of the Earth!\n\nThe circumference of the earth at the equator is 24,901.55 miles (40,075.16 kilometers).

If you were right at the center then the symmetry of the situation would mean that you'd be weightless since the gravitational force would be balanced all around.  \n\nSimilar situation if you were just a little off the center.  Most of it would balance except for a little bit.  Think about starting at the earth's surface and moving to the center.  You'd start at your weight and become zero at the center.  Assuming continuity and noting the nice behaviour of gravity then it must decrease in a smooth fashion.  If you continued through your hole to the opposite side you'd weigh the same but in the opposite direction, always pointing towards the center.

It would be on the exact opposite side of the Earth as yourself, in this case, the North Pole.

The earth is round and its gravitational pull draws us to its center.  Upside-down is really just pointing away from the core...from anywhere.

The 2nd answer is the more popular belief, keep in mind these are just theros, as no one to this day has been to the center of the earth.  So fear not, you can dig that hole in your back yard without fear of falling thru.

Assuming you have a tunnel that goes through the earth, take aside the fact you would survive the temperatures and such at the center, assuming there's no resistance (vacumn like environment), you would fall into the hole... accelerate to terminal velocity...pass the center, and slowly decelerating, until you reach back a speed of 0, where you will be at the other end of the hole, whereapart the whole process would start all over again unless you grasp the edge :)\n\nConsidering that the fact there's air, you'll encounter resistence, meaning you will accelerate to the center, start slowing down, but fall short of reaching the other end, then you will fall to the center again, fall even shorter of your original jumping position, and you'll oscillate back and forth until you indeed get stuck in the center of the earth.

I think,to a good approximation, at the centre you would not feel an appreciable gravitational field from the mass of the earth. \n\nIt's a nice result in physics that if you're on the interior of a spherical shell of mass then you feel no gravitational force. You can think of the centre as being surrounded by layer after layer of spherical shells of radius ~0 up to the radius of the earth.\n\nIf you do the calculation, once you start going interior to the earth the gravitational attraction varies linearly with distance from the centre-going from 9.81m/s^2 at the surface to 0 m/s^2 at the centre.\n\nOutrageous!

How about a bowl of water beneath it? Is that within the rules? Alternatively one of the other posters is planning to drill a hole through the centre of the planet, you could always use their hole, it wouldn't break then!

I'm sure physicists around the world ponder these questions on a daily basis.\nFirstly,astronomers believe that there is a super-massive balck hole at the center of our galaxy, the Milky wave. Through spectrometric measurements, they have shown that the large amounts of gamma rays emitting from it are due to the huge chunks of nearby stars and matter that it sucks in each second. It is believed that this matter is absorbed by the black hole and compressed into nothingness. However, some believe that some of this matter (including people) could be transported through some sort of tunnel into another part of space\n\n2. No one knows for sure if wormholes exist. But if they do, it could provide a way to travel faster than the speed of light like in star trek or other shows, the so called "hyperspace".\n\n3. Yes, if you dug through the earth, you'd emerge into space, with nothing under your feet. If you were to travel in such a "hollowed-out" tunnel, as you approach the center of the earth, the gravity would gradually decrease until it would be zero at the exact center. If you drop a ball into this tunnel, it would oscillate forever, assuming no air is present, like a spring with simple harmonic motion since the gravity is a function of depth.

up and down are directions from a gravitional center.  So, one would be digging down from anywhere on the earth's surface until he got to the earth's gravitational center...then he'd be digging up.

Well, you would not make it through because you would die in the middle from the heat.\n\nAssuming that there was no heat to burn you, in that case you would get stuck in the middle because of gravitational force.\n\nAssuming there was no gravity, you would probably not be able to make it through because it would be too exhausting.\n\nAssuming that there is nothing that could prevent you from doing it, either physical or geographical, then you would come out of the hole right side up.

you would be normal because you are already placed between the earth and the sky
