   There had to be two types of stars whose explosion created the   
   debris from which the earth and solar system coalesced, a   
   supernova which created heavy matter (above fe.) and a star   
   lower in the main sequence where iron is the final element   
   created within the star explodes. There should be remnants of   
   these stars nearby so where are they? There is a point in space   
   where every 26 million years average there is a extinction period;   
   sometimes massive extinctions. Ie Ordovician-Silurian, Permian   
   thisaaic - Jurassic.  This is the nemesis (death star) hypothesis.   
   Is it possible this "star" (if it exist) is a remnant of the star   
   explosion which gave up our solar system?
