Have absolute gravitational singularities ever formed?

[Loren Booda]

What of the possibility that dark energy prevents total gravitational collapse of black holes, and might also have helped avoid an actual singularity at the big bang?

You wouldn't expect dark energy to do that, because there is so little of it around. On the other hand, you might speculate that a unified theory will simultaneously prohibit classic singularities and explain dark energy.
