I don't quite get the article... I understand that the shrinking of the black hole will cease, if underlying space/time is discrete. And I understand that that will happen quickly from POV inside the black hole, and slowly outside. What I don't get is why once the newly formed white hole begins to spit out stuff, it will continue to do so. Why won't gravity pull it together agian?

Basically, the theory (at least as I understand it) says that the "quantum bounce" reverses the collapse process, so a massive object collapsing very fast turns into a massive object expanding very fast. The expansion decelerates because of the gravity of the hole, but the deceleration is not enough to stop it from exploding outward and redistributing all the matter that collapsed back out into the universe.

Think about how a Type II supernova happens: http://en.wikipedia.org/wiki/Type_II_supernova http://en.wikipedia.org/wiki/Type_II_supernova
