In the ontological thread, someone posted that I thought all stars went nova/supernova at 10by old. That is not what I said at all. I said:
> 
> The universe is 13.7 billion years old. The lifecycle of a star, before it goes nova even once, call it avg 10by. 13.7by-10by=3.7by. That would mean that the Age of any planetary body other than stars, since they are comprised of heavier elements, could not be more than 3.7b years old. Even if they were formed directly from the output of a single Supernova. The earth is estimated 4.6b years old.
> 
> Some will take much much longer, others not as long. -Supernovas are much larger than our sun with its 10 billion year lifetime. Being bigger they blow up much sooner. If the potential supernova is 20 times the mass of our sun it will blow up rougly 20 times sooner. Your formula is completely wrong.-http://imagine.gsfc.nasa.gov/docs/teachers/lessons/xray_spectra/background-lifecycles.html
