So I was curious about, what if we make a tunnel from one side of the earth, to the other side of the earth? Gravity is ofcourse always negative, which makes you "fall" and not "float".
If we take this image, let's imagine that the BLACK LINE in the midle of the earth, is a tunnel from one side of the earth, to the other side of the earth.
The red DOT is the midpoint, where something in theory, should happen to gravity that is out of our forces.
What would happen, if a human were to be in the red dot? Would the human just stay there for eternity?
Notes: Imagine that the being in the center couldn't kill you, neither would it bring you in contact of any substance. Just a long tunnel with nothing but the tunnel itself.
