If a hole were drilled from one side of the Earth straight through the other side would a thousand-pound steel ball go right through if it were thrown into the hole disregarding the heat and pressure?
It would fall through nearly to the other side, but due to friction (air resistance) it would not make it all the way through. It would then reverse direction, and return nearly to the starting point, then repeat this cycle many many times, each time decreasing in amplitude, until the oscillations finally came to an end and it would remain floating at the center of the earth. Basically, the same effect as a giant linear pendulum.
