To quote the website I obtained the density from http://www.astro.umd.edu/~miller/nstar.html its energetically favored to have protons and electrons combine and form neutrons and neutrinos.

Is that right? Its actually the neutron degeneracy that keeps things from getting denser. Higher densities are thought possible in a quark/gluon soup. Remember, neutrons are really not solid spheres. Quarks, electrons, and gluons are point like (as far as we can tell now). Dan M. _______________________________________________ http://www.mccmedia.com/mailman/listinfo/brin-l
