Black Holes Do Good Too

This article mentions an aspect of black holes of which I was unaware. Not all of the material around the black hole gets sucked inside. Some actually is accelerated and thrown far away from the black hole. This bit of escaping molecules may be the key to life in the universe. The black hole mixes things up and projects heavier molecules that often end up in stellar nurseries and form a new generation of stars. The article did not make it clear how helpful the black holes really are (I would guess that we do not really know), but it did point out that at the very least black holes do something at least mildly useful.
