Just Bin Thinkin',

If you dug a hole through the center of the earth,and jumped in, would you stay at the center because of gravity?

[Berkshirelad]

No.

Gravity is due to the mass of the planet and not a single point in the centre

[mrsmaveric]

depends on where you dug it i suppose if you dug it in australia could you fall up??? because oz is down under...

[factor-fiction]

... but you wouldn't keep falling through to the other side would you?

[DTCwordfan]

Just give you two spades, MR, and tell you to take your pick......

[bobthefisherman]

You would have to dig two holes, one in Britain, and one in Australia, due to the time difference, jump through one, then back through the other to see what happens......

[Cowtipper]

Inertia would carry you past the center. Getting the permits to dig would be the neat trick.

[mrsmaveric]

if we did that in the football season bob,maybe we could [due to the time difference] win on the aussie football pools..

[bobthefisherman]

Good Thinking Mrs Maverick, I'll speak to my solicitor about the permits.......

I've no idea how many times this question has been asked... same answer each time... supposing the hole went exactly through the center, one would accelerate at g = 9.8 m/s^2 (surface gravity) but your weight would lessen as you approached the center of the Earth, becoming zero at that point. This doesn't take into account any air resistance.
The person's speed, however would be near 17,700 mph, taking only 42 minutes or so for the entire trip (from one side to the other) before he would slow and reach the opposite lip of the hole... If nothing interfered, the person would fall back into the hole, accelerating again and reaching the lip on the other side... the entire round trip taking about 85 minutes... ad infinitum...
This doesn't consider if the hole was drilled from pole to pole or from a point on the equator to another like point...

[bobthefisherman]

I would start by placing a net (to catch me) over my predicted exit hole upon my return (where I started), and before returning, place a similar net over the exit hole on the other side. I can then stop for a few moments for consideration and a cup of tea.

Better to BIN your thoughts completely i would say. Have you been drinking perhaps?
