If you dug a hole through the center of the earth,and jumped in?

Would you float in the middle or something?



yes you would.


ignoring the temperature, and the problems trying to keep the walls from falling in, and scraping the heck out of your hide, as you whizzed down the tube, of course.





you'd probably yoyo back and forth for a while, and the gravity that holds you in the center would be fairly weak, so you'd be able to climb many miles up the tunnel before you'd feel much trying to draw you back to the center.




let's assume you could dig such a hole and decided to jump in. Actually, you would also want to assume you dropped in and make a number of other very technical assumptions to ensure you did not strike the sides of the hole as you fell down.





Now, you are falling inside this imagined hole through the center of the earth and are wondering what happens next. It turns out, the gravitational acceleration you experience will keep you oscillating from one side of the planet to the other forever. More assumptions are needed. This time you must also assume there is no resistance to your falling due to either air or any other phenomena that may characterize the hole you are falling through.





Why would you oscillate from one side of the planet to the other? Because the gravitational acceleration you experience will vary from one 'g' to zero 'g' and back to one 'g'. One 'g' at the surface of the planet from which you first drop into the hole and that is one 'g' of acceleration toward the center of the planet, zero 'g' at the instant you pass through the center of the planet, and one 'g' of acceleration back toward the center of the planet as you reach the surface on the opposite side of the planet.




You would burn in a firery death from being in a 100,000 degree(c) core.





THE DUD





Edit: its kind of hard to tell seeing that nothing can make it past the mantle. But gravity wise, no one knows for sure.





THE DUD (again)




yes assuming you somehow could keep the hole from caving in and also stay alive and get air etc etc




You would burn and die immediately.





Sorry, I should have said it nicer. But that's the truth.




you will be on flat land or if you dug it completely i don't think you will float but sink through the hole.




uh. you'd burn up. :( so don't try it.
