:Imagine the earth sliced in half like a huge peach with you standing where the removed pit once rested. Lets say the pit was small compared to the size of the earth for simplicity. If you are to stand on a scale where the center was, you would then weigh 3/4 of what you used to weigh on the surface of the earth. :Now, with no gravity overhead, you are being pulled in all directions except up. Not really, there is some small gradient to the force, but after superposition is considered the force is otherwise down toward the scale. :...This takes me back to my point; that if the outer matter in any given mass is acting on the inner matter with the same force, a black hole could never develop. Who says the net force on the mass at the center of the earth equals the net force at the surface? This is not correct. Black holes develop. :...inner mass attracts in and outer mass attracts out... The outer mass doesn't attract out. As we said earlier the net force on you in the hole at the center of the earth was zero. |
