“If there is nothing new under the sun, at least the sun itself is always new, always re-creating itself out of its own inexhaustible fire.” -Michael Sims
It takes the death of old stars to create the newer generations of stars in the Universe, and it's through the very act of that stellar death that "interesting" material finds its way into the Universe. This way, the subsequent generations of star systems will have more heavy elements, more rocky planets, more complex chemistry, and -- in the end -- more opportunities for life.
