If i was able to Theoretically drill a massive hole from one end of the earth to the other and jumped down the massive hole would i get stuck in the middle hovering there suspended because of gravity pulling all around or because of the fall you pass the center and yo yo back and fourth till you came to a stop in the center? i know you will die of hot magma but if the magma was not there what are your views?
