Your reply "Unless the hole is on the axis of rotation of the Earth", is right on the mark.

Not against either outward jet of mass in opposite directions when those tunnels open!

If the hole is completely straight through the Earth, inertia would tend to carry a body on past the center where the gravitational force is zero.and into an oscillation mode through the center. But the rotation of the Earth would keep the body scraping the side of the hole which would...

Newton's iron sphere theorem which is true for any spherically symmetric Mass.

Newton's iron-sphere theorem which is true for any spherically symmetric mass.

A 4-D black hole does not collapse and it does not evaporate. Spatial condensation continues on the mass inside to continue its growth. As mass slips over the edge to the inside, all motion inside that mass ceases and so does its time, but then quickly recovers as gravity approaches zero at...

It did not collapse because the spatial condensation expansion rate was so great in the production of the supporting 4-D ball.
