I have a question about digging a hole straight through the earth

If you were to do so, and jump in, I've heard you would go rite through and come out the other side at about the perfect speed to step out of the hole and walk off on the other side. Sort of.

But, If you were to be lowered into the hole, all the way to the very center and let go, would you just float?

Edit. Ignore the temperatures, just concentrate on the mass and size of the earth.

Fun fact: If you jumped into a hole all the way through the Earth that was somehow made frictionless, you'd reach the other end of the hole in about 42 minutes.

But that isn't the fun part. The fun part is that this is true *whether the hole goes through the center of the Earth or not.* It's equally true for any tunnel through the Earth that follows a chord.
