Why does Pauli's principle hold? Is it a mathematical principle or a
heuristic argument? And why does the principle break in sufficiently
dense objects which then collapse to form neutron stars?



Although you are going to get responses talking about
fermions, shells, energy levels, groups, symmetries, and such,
I think the simple answer is (No smart ass responses please.)
that Pauli exclusion principle tells us about the
physical shapes of the most fundamental objects,
at a particular temperature and pressure.

These most fundamental objects are atoms.
The Pauli Principle is a direct consequence of
atoms' geometry.
Electrons are arranged in rings which rotate while
precessing. Because of this, only electrons exactly
opposite each other on each ring can possibly
follow the same path.

The reason electrons are arranged in rings
is because when you accelerate an electron
it produces a magnetic field at right angles
and these magnetic fields allign.
