If you could dig to the other side of Earth, what would happen?

since you said "IF",  I think somewhere around the middle gravity will reverse on you and you will have to turn your body around so that you can come up on the other side head first.

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.

Settle down at Moon. or Dig 100 meters down the earth construct a room there. Go to underground well before the nuclear attack. You are safe.

Ask those living in other planets!

All the plutonium in the world will not be enough to rock the earth's tilt (but it would kill most animal and plant life, that's another issue). But to answer your *hypothetical* question, this is what would happen:\n\nEquator: Cooler throughout the year.\nTropics: No change in summers, much cooler winters\nTemperate regions: Very hot summers, very cold winters.\nSubarctic: Hotter summers, colder winters.\nArctic: Much warmer summers, not much change in winters.\n\nSo presumably Antarctic ice would melt and significantly raise ocean levels.

You'll never get to the other side, first because if it was possible, you'd burn in the central core. But more importantly, the fact that you fall into the hole is because you're attracted by gravitation force, so you're attracted to the center of the Earth. The closer to the core, the stronger the attraction force. Therefore, if you reached to center of the Earth, you'd stay there and would not be able to continue your jouney to the other side, unless you had a power device that helped you get away from this force

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.

Dude, the world would end up being a s"hit hole..but it woud be fun ride

Try to look for an earth science book that has pictures of the continents one million years ago and at the present, with arrows showing the direction of drift. Then try to imagine doing the drift again. I tell you, this would require huge amounts of brain power.\n\nI can tell you this: Los Angeles will go north along with the rest of California, the Himalayas will rise higher, the Mediterrainean will disappear, Australia will move northward, squishing Southeast Asia, Central America will move north, Antarctica will spin, and so will Asia, more islands will arise in the widening Pacific, while Africa will be split in two. You do the drawing.

You wouldn't. It would melt as it neared the center of the Earth. Assuming you are asking the hypothetical question, it would go to the middle of the earth and stay there...that is where gravity pulls from.

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

It's 4000 degrees C at the center of the Earth. That'd pretty much do the trick.

Where are you going to get a new earth from?

we will never know whats going on out there if we dont explore it.\nmaybe there is aliens out there who would want to communicate with us or there may be some asteroid out there that is going to hit the Earth in near future.

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

The world would come together in panic ... "Where the &*^^ did the US go?"  Conspiracy theorys would abound.  Tensions would be high - no one would trust anyone else.  Did an experiment go wrong?  Did one country develope an incredible weapon?  Are the aliens finally attacking?  Did God decide simply to wipe them off the face of the earth?  Different groups would claim responsibility -- most of them groups no one has ever heard of.  And all over this great world, there would be office pools involving which country would disappear next.  (My money would be on Akrotiri - but really, if they disappeared, who'd notice?)

This process is long over due. \nIf the poles reversed it would disrupt Earth on a massive scale. To imagine the scenario look at the complications of The Bermuda Triangle. It may sound fanciful, but, this anomaly is occurring where the predicted north pole will end up. At the moment it is fluctuating between the two poles. Aircraft, ships and modern vessels have disappeared because of this swing. Radar goes hay-wire and so too does electronic equipment.\nThe last one recorded occurred before the last ice-age. This brought the speedy death of millions of creatures known as the Mega-Beasts. There is a place in Russia, (the spot where the south pole sprung up) Where thousands of these Beasts lie dead. Twisted and crushed with trees and vegetation, smashed together in gruesome contorted throes. Massive lava flows are mingled in too, on a truly monumental state.\nIt lasted only for a few years but the impact was colossal!!!
