eg. from UK to Australia through the core (if it was possible) and you jumped into it....what would happen when you exit out in australia???

The terminal velocity for a human with arms and legs spread is approximately 120mph. This equates to a velocity of around 53ms-1. Terminal velocity is partly due to gravity, so once you have gone passed the centre of the earth you lose gravity "pulling" you, so would naturally slow down, and in addition, the gravitational force (which on Earth is 9.8ms-2) would also start acting as a brake. Friction with air wouldn't provide any real "braking" as this is already accounted for in the terminal velocity. I'm not feeling clever enough to work out how far you'd get before gravity slowed the descent to 0mph and then returned you the other way, but i'm pretty sure you'd not reach Australia. You would end up "yo-yoing" back and forward, each time travelling a slightly smaller distance rather like a swing that is pushed then left to stop on it's own accord until you finished in the centre of the earth and then had to climb out one way or the other in your heavy heat-proof suit!

If you made it just past the core, you wouldn't exit. You would be spewed, along with the rest of the molten iron, out into space just prior to the earth collapsing into a miniature version of the Milky Way. Perhaps, if you attracted enough iron, you would become a small moon or planet. If you didn't, and remained mostly hot air and gases, maybe you would become a miniature star. More than likely, you would become just a piece of cosmic dust.
If there was no molten iron and rock, you would get stuck against the side of the hole about in the middle and have to climb out.

You would be stuck in the center. Just like being let go on a swing. You will continue to swing back and forth slowed down by friction until you hit the bottom(middle) and you'll be pulled directly straight IN. Not up down or sideway but rather IN(the 4th dimension). Your arms will be pulled down and your feet will be pulled up. Imagine the source of gravity was located in the pit of your stomach. There would be gravity and it would be much more intense than on the surface.
**Imagine when on the swing that the forward and back motion is actually up and down as in falling through the earth and side to side is right, left, ect. There are your 3 dimensions. But now add in the the elevation (straight up and straight down) and that would be the 4th dimension.** The height of the swing determines how quick you fall just as the amount of mass determines how steep the hole is in the 4th dimension. If the hole were straight down that would be a blackhole, there would be no swing, it would be a freefall.
To envision something so complex you have to morph into something the human brain can see and visualize. To visualize the 4th dimension as it exists is impossible, we just don't have the ability to see it. We know it, just can't draw it. It is 100% impossible to draw.

You'd first burn to death from the heat of the earth's centre, turning into ashes (carbon). Then as it would take you millions of years to work your way through the earths crust to arrive on the Australia end, you'd have been under so much heat and pressure that the carbon of your ashes would have metamorphasised into a massive diamond! You'd obviously be dead but at least you'd be sparkly!

You would fall faster and faster until passing the center of the Earth and then slow to a stop at the surface in Australia, and the fall back again, if you didn't grab onto something. Neglecting air resistance and all sorts of other practical problems.

Come on grow up and quit looking at things that will not be possible.What if is not a scientific approach. Even if u drill a hole through the moon u cant the maximum for a well is only 25,000 ft.

Practically you cant do that due to molten megma in center of earth, else if you get success to dig out the hole and drop a stone in it, it will work as simple harmonic motion.

For all those who say it is not possible, remember the question stated, 'if it was possible' we all know it's very hot down there.
I agree you would end up in the centre-ish, as the gravity between you and the Earth would be equal towards the equator.

You wouldn't get that far.
The friction of the air would slow you so that you'd only get so far the other side before coming back and that you would oscilate back and forth until you'd stopped.
Oh yeah - you'd also be a small piece of carbon by then as you would have been frazzled by the heat.

You wouldn't make it to Australia, as you would be burnt to a crisp in the Earth's core.
