Get this: after a star like our sun dies it eventually becomes too dense and heavy to sustain itself against gravity, so it implodes and then explodes (a super nova), releasing the most powerful energy in the universe for a split second. But it doesn't cease to exist. Matter is still left. It then turns into a small 20 foot neutron star, the densest things in the universe. One cubic centimeter of a neutron star, the size of a sugar cube, weighs as much as all the cars in the United States.
