You're doing better, but you're not there yet.

Please cite a reference that we can look up somewhere. This theory
is still outside the bounds of physics as I understand it, but
closer. The problem is that gravity is hard to stop, and the
forces needed to hold up the weight of the planet require that
the core have a particular compressive strength at each depth.
The only way any part of the core can become less dense is if it
can do so by while still maintaining its compressive strength.
Temperature is another factor.

Would a geologist on the list please help me out here? Danny's
theory is a bit harder for an amateur like me to refute than was
the pole shift.
