Gravity Wall
dumb question about gravity, but I need an intelligent response?
If you really could dig a hole China, and you do not, and you fell, did you stop in the middle because of gravity and just float? Now, think if we strengthened walls so that he wouldnt give in and get crushed. would you just float in the middle? would seem to be too dense to go throw? Would you turn in the size of a pea before you there? Please give me your opinion.
As a thought experiment here how it is generally explained: Assuming you could make a tunnel through the earth that would not be crushed and destroyed by heat and temperature therein and assuming you do not hit the sides when you jumped in and assuming you have air and water and all for survive and, assuming that the point of entry and exit are the same height above the average level of the sea, you would fall toward the center, which accelerates terminal velocity of about 120 miles an hour, if that's not really important as you will see in a moment. As you approached the Center of the Earth, gravity would change the position, you will be surrounded by the mass of the earth and gravity would pull you from all sides, you which mainly microgravity. You go after the center of the earth, almost all the way out the other side, but now you would have any the mass of the earth pulling on you from the other side if you would not quite all the way, you lost a little momentum for the transition by center, due to the change of gravity. The drag of the air you fall would be a factor, but even without it you would not make it all the way out of the other side. This oscillation will continue in much the same way, which reduces very slowly until you have been trapped in the center of the earth.
