How far do you have to dig to get from one end of the earth to the other end ?
464580
About 8000 miles.\n\nThe radius of the earth is approx 3959 miles - you would have to dig twice that distance, or 7918 miles.

It is a ways to the east of its starting position.  The exact distance would depend upon the latitude of the location(s) in question which I don't know off-hand.  (Thought now I am curious and will probably look them up and do the math after posting this!)\n\nThe reason for the discrepancy is that the surface of the earth is the surface of a sphere, or more accurately an ellipsoid, and the definition of "east" and "west" are simply that the north and south poles are to your sides as you travel.\n\nIt can easily be illustrated by supposing that the swallow were to travel from the equator to, say, within about 1.27km of the north pole, and then travel only 1km east.  At that distance from the north pole, a 1km trip east (remember, the definition of east is to "keep the north pole to your left") would make a QUARTER CIRCLE around the north pole.  Then, the swallow travels south again all the way to the equator.  It is clear that both the north and south trips would be equal.  However, it would then have to travel westward one quarter of the way around the equator to reach its starting point, or about 10,020km!  Quite a far cry from the 1km east that it travelled.

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.

Mankind will probably be able to go there, but it is quite far in the future - I'd say at least 20 to 25 years away.  Whether or not interest in doing so continues will depend on what is going on right here on earth, and whether we have the will to spend the money on the project.

It varies a bit since the earth isn't exactly round, but an average of 12755 km over the equator and about 12155 km over the poles is about right I think.

ALL practical stuff aside:\n\nI hypothesize it would be headfirst, because gravity would still be sucking you towards the center of the earth, not the surface towards which you were digging. Halfway through your digging I guess it would shift from under your feet to over your head. \n\nAlthough, if you dig yourself into the pit of magma at the core of the earth you could always come up in a volcanic eruption, in which case, on the plus side you oculd be in hawaii or somewhere cool but all of your parts would look about the same so it wouldnt matter.

It all depends on whose point of view you are going from.  If you go from the person digging the hole, then they would say they are digging down.  If you go from someone at the North Pole, then they would say that the digger is going up.  Someone on the equator would say that the digger is goibng across.\n\nIt's all relative.

You need a Geologist!

895.83 miles, give or take a few. Have you heard of google earth? It's a free download of a gps globe of earth from google.

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.

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

It depends on where you dig the hole !\nIf you dig it on the north Pole (or south Pole) you would accelerate until wind drag compensates for gravitational forces (around 200 km per hour, approximately 120 miles per hour)\nThe gravitational forces become weaker the more you enter the center of the earth (and vanish at the center) so your speed will decrease to a minimum(some speed might remain, because wind drag increased with speed).\n\nI think that you would get stuck near the center of the earth.\n\nIf you dig a hole on the equater, you will probably notice after an hour or so that the wall of the hole seems to get closer to you.\nThe reason is the rotation of the earth: on the equator, you have a speed of some 40,000 km per day (24,000 miles per day - 1000 miles per hour).\nAt lower heights, the earth will still turn in 24 hours - but the circle is smaller, whence the speed.\nAs a consequence, you are likely to scrape against the wall.\n(and remain stuck in the center of the earth as well).

well if you are exactly in the middle, then any way you go will take just as long right?\n\nthe fastest way out of there would be jumping out cutting your leg and wait for a shark.. you'll be dead, but not in the middle of the ocean anymore

Approx 12,451 miles.  See below (Divide the circumference by 2 since you are only going half way around the world)

how much depth you have to work with. Will things like sewers, TV cable, fiber optics, electrical lines, gas lines be in the way? Also, what is the geology of the ground you're going to tunnel through.

Assuming that you are driving from the South Pole to the North Pole and there is a paved road connecting the two, it would be roughly 12,450 miles long.

The deepest research borehole ever drilled was in Russia, on the Kola peninsula. Over a period of more than a decade a huge rig, built specifically to do this, drilled to over 12 kilometers.  Digging that deep or deeper is _very_ hard as at those depths the pressure exerted by the earth begins to exceed the structural strength of most metals, so the earth actually begins to crush your drill.
