I'm gonna dig a big hole in my backyard; Always wanted a pool of my own :P
Way off the south west coast of Aus. Bummer. I always believed the cartoons as a kid of digging up a China-man. :)
Ha Ha....ME TOO! I always wanted to dig a hole to China just like Bugs Bunny. I still say that too my kids when they are digging in the yard :)
It put me southeast of Madagascar, in the middle of the Indian Ocean. Does anyone know how many miles it is to go straight through the planet? Oh no, another brainstorm...transportation direct route through the earth!
Because my hole ends up in the ocean. If I actually could dig the hole without burning up in the magma... would all the water from the other side rush into the hole and come back to flood my side? Or would the water stop somewhere in the middle of the earth?
I am getting a headache.

What happens when you fall through a hole through the centre of the Earth: [straightdope.com...]
It occured to me that having a small "black hole" to work with would simplify the hole-making process. If you try it, make sure you give it enough of a push to escape orbit afterward, or the whole planet will be consumed. :P
but wait,
since the center core is very dense, and being closer to it would increase your g proportionally squared. maybe you would get heavier as you get into the core, because of proximity to the denser mass. But then you'd keep digging through it, and then what? at some point "up" would become "down", so there has to be a "neutral" where the g-line crosses zero.
Find the point directly opposite you on the other side of the Earth. For a location on the black outline map, that spot on the inverted red map (or vice-versa) will be your Local Nadir, or Antipode.Examples: Spain is opposite New Zealand's North Island. The center of Brazil is opposite The Philippines. Botswana is opposite the Hawaiian Islands.
It seems that there's very little "overlap"; not surprising, I suppose, considering that 70% of the Earth's surface is ocean....
you would probably not stand the core temperature of earthOne of my 6 year old's science books says the center of the earth is iron & nickle, intensly hot but in solid form due to the extreme presure. How do they know, I ask?

That is what one of my co-workers suggested, and he presented a good explanation.

Seismic measurement. The way soundwaves (either from detonations or real earthquakes) travel through the globe tell a lot of its layers and materials. Of course you need a whole bunch of listening devices, but geologists and seismologists use the internet too to coordinate experiments.
