A neutron star.
It becomes less dense. Ice will float on water
Neutronium, hyper-dense atomic nuclear material stripped of all electrons.
At the center of a black hole is a mass that has collapsed to an infinitely dense point.
Water is more dense the colder it becomes. It is also more dense the saltier it becomes.
A neutron star is the collapsed core of a star in which atoms have been crushed, and electrons have fused with protons to form neutrons. The collapse stops at this point. A neutron star is extremely dense but has a finite density and emits radiation. A black hole is an object that has collapsed completely to an infinitely dense point. It cannot really be considered matter at this point. Around this singularity is a region of extremely strong gravity and highly distorted spacetime from which nothing, not even light can escape.
