heres the real question,
why do people try an f**k my head in before an exam

i dont need this

no gravity = out feet first, just like digging a big hole down into a cave
gravity = once your past 1/2 way you have to dig upwards and you come out head first (imagin digging a hole 10feet deep, then you dig 10 feet to the left, then you did up again, those 10feet down and up arre a mini version of what you would be doing!)

I agree with knighty.

If there WAS a hole through the earth and u jumped in feet first youd come out feet first (why would you spin round in the middle? ud speed up as you fell and then slow up as you come towards the other side. then ud go into SHM as said before, but you wouldnt "spin" round)

however if ur trying to dig this hole, after halfway ud be being pulled back towards the centre of the earth so it would b like trying to digg upwards. which is a lot easier done head first.

ignoring the heat pressure and bizzarness that goes on at the centre of the earth etc etc.

Episode 2x13 clearly explains what happens when you dig to australia tbh.

You get a huge volcano that fills the country with flood basalt and everyone is really peed off at you?  

A better question would be why would you bother doing this in the first place.  Surely this one of sciences most pointless questions.

Because were all bored  

Pffft
