ok, this is a hypothetical question that I as nearly everyone I meet, and most of the answers comeback with one or two conclusions, I have only ever heard ONE turely unique "third" conclusion. lets see what you all think...


Keeping in mind, I realize this is impossible, but just for the sake of discussion lets say it can, and has been done.

Someone has drilled a tenfoot wide hole (or tunnel) through the planet earth <right through the center of it> and they have lined the outside of it with a material that is totally impervious to heat of anysort, so the temperature is "room temp" all the way through nad the walls keep their form all the way through. Like wise the hole or tunnel has been pumped full of oxygen all the way through keeping the air density the same completely thoughout.
So yeah ,one day your walking along and you fall into this hole... What happens? do you stop flat in the middle of the earth , or do you shoot out the other side, or is it like a bungee cord effect?

What would you think?

Whatever it is you're smoking, you better start sharing it...

Have you read the "gravity train concept"? It makes sense if you know basic physics.


In a frictionless environment any hole, independent of the angle towards the center of the earth would yield a perfect slope of acceleration that would have vectors equal to the inertia created in the fall.

Regardless of angle or distance the math works out to roughly 42min time to pass through the earth.

Here's the catch - you said "air density" - so we are assuming that there is in fact friction of sorts.

factoring this in makes travel through the earth impossible - and yes, the "bungie" effect is what you would observe.

It's actually a type of spring force...

not really a question that hasn't been defined by physics...

Still, nice to see someone posting something that requires a brain.

I'll post something for you Pretty_Good...

nice reply, but heres something to think about... what if the hole is against the axis of the earth? If you can infact get past dead center would you not be shot out the other side? ie; trebechet reaction?

Personally LIFE would END if we could ever acheive that HOLE!

Because the cores integrity would be breached, and we would all end....lol

But to live that jump through, You would, in thought anyway.

Do the bounce back and forth in that hole until your complete

back and forth motion stopped..

Like the clacking swinging steel balls, between the racks...

My guess anyway.....lol

I don't think so - here's why...

Ok - take a hole in Spain which connects place in New Zealand. The tunnel would be straight down because its route would intersect with the Earth's center, making it a pure and sudden free-fall. You would accelerate to a maximum velocity of about 17,670 miles per hour before beginning to decelerate, and it would travel in a straight line for 7,290 miles. 42 minutes after falling, you would gently stop in New Zealand.

Factor in air resistance(friction) and you never make it to the other side.

Trebuchet principles don't apply in any way to this. I really don't see how it would.

This was calculated for Newton I believe - I'll find more about it if you need...

the earth is rotating at aprox. 1041.66 miles per hour though, and your path of decent would alter in the hole,no?
I mean, take a marble and drop it though a christmas warp tube it falls straight through, but turn the tube in a windmill fashion while the marble is passing though and it gets launched out.
This wouldnt work the same?

*is lost*

Sounds like fun though.

That's kinda, possibly possible I suppose - but you're also assuming that the object falling isn't being subjected to the same rotational vector magnitude when it falls. The only thing that would mess it up is, once again....air

With the "tube" or the basic Trebuchet you're introducing external forces to cause the disturbance...whether it's you spinning the tube, or the counterweight being pulled towards the earth...

I'd have to spend a few hours on the math to see if air would create enough disturbance to modify ones path that much...my guess is absolutely not

and in that case you may as well throw in the impossibility of calculation due to forces exerted by the person falling being unpredictable...


It's easier if you say "drop an inanimate object" and "don't consider friction"...

To say the earth still had a pure center gravity.
Then the original force falling, would have its own density
of fall,,,,,,,,,,,,,,just to come back less a bit each time BECAUSE of the friction involved with its constant degenerative
forces as it goes between the CENTER POINT of the earths gravitational pull...and sometime stoping at the center of the earth, or its pull center..

So let's say I jump in with the worlds largest and strongest bungee cord that extends only to the center of said hole.....and I have a chicken under one arm, and a fifth of Jack under the other.....but my lungs had recently been replaced with a fully functioning set of gills.........and I am claustraphobic.....?? Can I still hear a tree fall in the forest if I am not there?

Aww... what a lucky chicken!

ur trying to revive a dead brain what a pain

urm gee i can barely function on a sunday morning lol never mind poder this one one urm do know one thing if i fell in this hole of yours would be screaming thats for sure

i would think you would bounce back and forth untill you stopped in the middle, but with the earth spinning and how long it would take to fall down this hole would you end up spiraling down there as you fell?

LMFAO

YEA WAY TO EARLY FOR THIS LOL

would'nt ya bounce around ...then have to climb out the other end? I neeed coffeeeeee!

Wouldn't the Morlocks get you?
