Gravity at the center of the Earth cancels itself out. The pull becomes outward in all directions simultaneously. Your model does not take this into account. It is an improper application of your formula.Maybe I wasn't clear, the further one is from the center of gravity, the less gravitational pull that object has on the individual.
This is represented by the formula F=g(m1*m2)/r^2
Where F= gravitational force
g=the gravitational constant
M1 equals the mass of object 1
M2 equals the mass of object 2
R=the radius or distance between the two objects center of mass -

Falling through the Earth is not like falling toward it through various air densities.The calculation is correct. This is the highest speed a skydiver will have in spread eagle position during the fall before opening the parachute. But as the velocity depends on the shape of the falling object, D in the equation will change if the skydiver go head first with arms to his body. Kittinger has the record of 274m/s (reliable) or >300m/s in more unreliable measurements.
But this is in air, valid for an ordinary skydiver.Improper model application.

Baron Von Fritz wrote: Ah, just looked back in the 'ole book...By the equation shown in here, the gravity slightly decreases gradually as you go down and as you go further up. So I was incorrect clearly. Hmm, but a bottomless pit? It would have to be in space to fit; not the earth. Unless it was like Portal...In which case, you would be torn to shreds by the speed. There is no gravity in space except on planets and certain asteroids, so you would not be "falling". It would have to be a vacuum in space. Gravity would have nothing to do in the equation.
Speed does not tear one to shreds. Only rapid acceleration at greater than 20G forces would damage a human.
What part of 1G or less free fall produces 20Gs?
Every time a a space walk happens at Mach 26, are they torn to shreds?
Double dumbass on you! 😄

No gravity in space?
WHAT?
Space IS gravity. Ugh.

I'm in bed, sick today, so I made this. This is the correkt formula. F=GMmr/R^3 where capital letters are the earth's gravitational constant G, mass M and radius R. m is the mass of the subject and r the radius where m is.Nice Natalie wrote: Gravity pulls towards the center of mass.

I'll post it again.
What is the air density at the center of this new sphere/taurus? Depends on how wide the hole is. It is unknown to me, so I throw it out. I would assume it would be very complex because of the effective zero G at the center, the temperature change at the center, the pressure of 1 atmosphere minus the volume of the hole pushing down... Complex.
I throw that out and just deal with gravity in a vacuum.
If you don't visualize and understand the forces at work, your formulas won't help you answer the numerical measurements you ask of them. You won't know which formulas to apply to the question.

So, at what level (funny huh) do we want to solve a problem? Taken into account that to come to the earth's core we need to pass a melted outer core, we either say "we can't make a hole here" or we say "if we could, how would the gravitational force look like" or something like that. The physics litterature are full of examples that makes such assumptions. But I agree with you that you should think before you present something, which I did.

Backflips. I would do A LOT of backflips. And here's a cool thing to add to the physics debate: disregarding friction with the side of the hole, it would take 42 minutes to go end to end no matter what it's position is in relation to the center of the earth, as long as the hole is straight.

The amount of ignorance in this thread is unbearable. Everyone knows gravity pushes, not pulls...
In all honesty though, this is the level of ignorance you guys are showing. You take a model and apply it in the wrong places. This is why it's important to know where the model comes from, not just the numbers.

No such thing as a bottomless pit. If you are 'falling,' there must be an object that is large enough to create gravitational acceleration. Your question is a paradox, and cannot be answered. If you are falling, it is towards another object, and there must be a measurable distance.What would you do while you were falling?

um, maybe I'm not nerdy enough, but wouldn't you just incinerate in the immense pressure and heat produced in the earth's core? your bottomless pit wouldn't even have to go that far.

No if you could survive the fall which you wouldnt you would incinerate, you would then launch the opposite direction aproximatley 1/3 back towards the otherside of the earth.Would gravity equal out when you reached the core? Would you just float in place then?

How is motorcycle accident like a bottomless pit.Well, I forget how this goes but, if your brain senses a situation like this it would make you pass out, my math teacher was in a motorcycle accident and he passed out almost immediately after contact.

I love how this is all hypothetical and people are treating it like reality. It's hilarious.
And I also love how certain dumbasses *cough* Baron Von Dumbass *cough* are still defending what they say even though it's wrong and Note has posted links to actual facts. -

My pockets always have a
knife, 100 or so feet of 30lb test kite string, and a rock.Never know when your gonna have to tie the rock to the string and Hit somebody
