This paper uses a simple thin shell model to illustrate that, contrary to intuition, gravity sets no lower density limit for collapsing stars. Instead one should expect the density to fall over time because, as the object settles and entropy increases, spacetime will stretch in the radial direction, increasing the volume of the object without changing the surface area.

This paper explores the possibility of such gravitational quantum reflections, and shows that potentially all incoming particles will be reflected before passing the black hole event horizon. This would make gravitational quantum reflection a phenomenon preventing gravitational collapse from forming a central singularity.
