If you cut a hole in the earth and there was no lava etc, from one end to the other and jumped down....?

Question

What would happen when you reached the exact middle ?

Answer 1

Uncle Al and soccerdude are correct - which of course is why they get the "thumbs down". In the absence of air resistance, you would pass though the centre of the earth at 17,500 mph and then decelerate until you reach the other end of the hole. Then it starts all over again...

You don't get "squished by gravity" - gravity gets less and less as you approach the centre. You won't just "float there" either because you are moving very fast when you arrive, so you shoot straight past the centre, slowing down as you approach the other end of the hole.

Answer 2

You would be barbequed long before you got to middle, not because of lava ,but , by the fact it is hotter and hotter the deeper you go. See:

What else goes on in your head anyway? Much? not much? Lotsa stuff? Are you taking any kind of medicine? You should drink tap water like everyone else. It'll make you stupid and such questions will never again cross your inquisitive mind.

Answer 3

At the surface, you feel the gravity due to the total mass of the Earth.
At the middle, you are attracted by two half Earth masses (one on each side), and the resultant gravity force is zero: you "float" there.
(that is, ignoring pressure, temperature, and that the Earth core is solid Iron!)

Answer 4

If your hole is aligned with Earth's spin axis (no Coriolis force to grind you against the walls) you would accelerate downward to the center (maximum velocity, zero acceleration) then decelerate up the other side, then back... in simple harmonic motion. The round trip (absent air resistance) would require about 84 minutes.

With air resistance you get damped harmonic motion.

Answer 5

Fly right past it. you would end up on the other side and once you came to a stop you would fall right back into the hole to continually move across the earth

Answer 6

you would pass a couple 1000 ft. from the middel then come back and do the same thing except fly less ft. ect. In reallity if you were in the middle the earth's gravity would be all on you and the earth would cave in on you with over 3,000,000 psi.

Answer 7

You would probably strike oil while digging the hole... and decide not to jump after all. lol

Answer 8

You'd carry on until you fell out the other side perhaps?

Answer 9

because of gravity you would stay in the middle unless you climed out.

Answer 10

you would float in mid position. (ignoring problems of rushing past the middle, then falling back again and again, and being crushed by air pressure and the fact that it would be pitch black.........
