Drill a hole through the Earth and drop a rope ladder down?
820907
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.

Assuming that it could be done, that the tunnel wouldn't be filled with magma, that the earth were not rotating, and that we made the tunnel into a vacuum, then the ball would fall from one end of the earth to the center while accelerating with non-constant acceleration, then continue to the other side of the earth but slowing down as it fell up with non-constant acceleration.  This is called simple harmonic motion and it would continue for ever.  If the tube was not a vacuum then the ball would initially speed up.  But as the gravitational pull the ball felt weakened and the air resistance increased (due to increases in air pressures at increasing depths) the ball would slow down.  In the end the ball would stop at the center of the earth.  If the earth were allowed to spin during this experiment, then unless the hole were drilled from the north pole to the south pole, conservation of angular momentum would cause the ball to crash into the sides of the tunnel as it fell and friction would cause it to slow until it came to a stop at the center of the earth.

No we don't have the ability now, not only is the temperature too great, there is way too much pressure for us to overcome. It would crush anything significant before we got to far. \n\nThe farthest down that we have been is only a few thousand km, and that with a tiny drill.\n\nThe deepest holes in the crust are natural. Volcanoes bring up material from tens of km depth. The crust thickness averages about 18 miles (30 kilometers) under the continents, but is only about 3 miles (5 kilometers) under the oceans. It is light and brittle and can break. \n\nHere is a great article that explains a lot:\nhttp://www.livescience.com/technology/050407_earth_drill.html\n\nThe reason we explore space more, is because not only is it easier to accomplish, but it is also far safer and less costly. I agree though that exploring below the Earth can be quite rewarding, but we simply can't do it as of now.

Think about the distances involved.  The supports for the tunnel would be impossible.  Also......even if it was possible....remember that once the tunnel is out of the atmosphere it would be bombarded by meterorites, space debris, etc.

yea,jump out of the cockpit.\npull the ripcord.\nsee the 60 plus size underwear take shape.\nglide toward earth while on the seat of your pants.\nhope the shit don't hit ya,on the way down!!!\n                God Bless

Let's imagine that there's not lava inside, then as you ascend, you would slowly slowdown, at the center of the planet you wopuld experience zero-gravity, then if you push yourself towards the south pole, you would have to climb out --- you would not be falling, but climbing now.\n\nSo you would come out head-first.\n\nBut it is technically impossible, because of the heat and the pressure at great dephs.

You could do it the risky way, by sailing to the edge and hoping the current pulling water off the edge doesn't get you, too.  I don't recommend this.  The young men in my village (I live on an island close to the edge of the world) used to do this on dares, until we lost three young husbands and twelve manlings on an ill-fated drunken bet.  There was such a shortage of men we had to dress some of the maids in armour and set them to the oars during our next raid, just to have enough people!\n\n(Some people are so ignorant -- I'm still chortling.  Next I bet your friend Eric Halfwit will tell you that thunder is created by something soft like clouds rather than by Thor's mighty hammer!  Or that the sun is made of flaming air, rather than the shining Goddess Sol, fleeing across the sky from the wolf Skoll.)\n\nThe safer way to prove the earth is not round is by digging a hole deep enough that you come to the bottom of the earth, then you can stick your heads through and show him how the earth rests on the back of four giant elephants.  The bottom of the earth has no hills or mountains, so it's easier to see its flatness, too.\n\nPlus, how could it be a pig's bladder?  Wouldn't it pop and fly out of its place in the center of the universe the first time somebody dug a well and punctured its surface?  Hasn't Eric Halfwit thought of this yet?\n\nThis all shows that too much thinking is dangerous.  We should be making babies and pillaging villages -- ideas like that may anger the gods and ruin next year's crops. . . in the villages we raid.

Run around the earth really fast.  Cross as many time lines as necessary to get where you want to be.

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.

Buy rope and 4 wooden poles. Use 2 mattreses underneath.

Well you would only be able to dig a certain distance, then you would have to drill through IRON and ROCK. THEN you would have to deal with the little warm place called the MOLTEN CORE OF THE EARTH. So no even IMAGINATION wont do it. Put down the bong.

tie a string to the tooth and on the other end of the string tie it to a car and have someone takeoff

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.

The deepest "hole" drilled into the Earths Crust was 4,644 feet deep. Scientist were trying to reach the Moho, a boundary formally known as the Mohorovicic discontinuity. It marks the division between Earth's brittle outer crust and the hotter, softer mantle

There has been quite a bit of talk lately about building a space elevator, which works the opposite way; hang a cable from a satellite in geo orbit down to earth, then have an elevator climb up it (see wikipedia: space elevator)\n   In that case, the tensile strength of new nanotube materials is just high enough to make it possible (steel's strength-to-weight is far too low).  Since most materials are much stronger and more stable in tensile strength than in compression, building a tall building to geosynchronous orbit is probably impossible from a materials point of view.  On the other hand, you could build a building lower than geo orbit, but anything released from the top would fall to earth.  You'd have to launch rockets or use a cannon or railgun or something from the top to accelerate them to orbit.

At about the center of the earth you would probably burst into flames do to the magma.if you survived that you would be upside down (relative to the ground)
