With all reserve we advance the view that supernovae represent the transitions from ordinary stars into neutron stars,which in their final stages consist of extremely closely packed neutrons.

Fig. 10.2A gaseous star of a few solar masses and radius of the order of 10 million km implodes and becomes a neutron star. Since a star is essentially made of hydrogen, initially the star consisted of roughly protons and equal number of electrons. According to Baade and Zwicky, somehow all these protons got converted to neutrons! A neutron star is just like a gigantic atomic nucleus, with the neutrons practically touching one another. Under such conditions, the density of matter would be g cm. This is, indeed, the density of atomic nuclei that we are made of!
