Would the big rip scenario be able to overcome even the binding force of a black hole, and if so, what sort of energy would be released when breaking the bond in a singularity.

After reading A Universe from Nothing a few months ago I had been curious as to the fate of the universe whenever the expansion of space was accelerating exponentially and I came upon the big rip hypothesis.

Upon thinking more about this recently I began to wonder if the atomic bonds breaking during this process would be releasing energy akin to nuclear fission, and it also occurred to me that beyond everything else I had thought about breaking apart during the big rip black holes hadn't once crossed my mind.

My question is essentially, should a big rip scenario occur in a short enough time frame for black holes to still remain in the universe would the expansion of space be able to achieve such a rate as to break apart a singularity, and what sort of energy would be released in this situation.

All black holes are expected to evaporate over time by emitting Hawking radiation. So realistically a singularity shouldn't persist over time even if nothing close to a Big Rip happens.

Ignoring that, though, then a Big Rip still wouldn't "rip a singularity apart." The thing about a cosmological solution like that in a Big Rip is that it describes the growth in the separation between two otherwise stationary points. But this sort of model is never going to cause two objects at the *same* point to suddenly become separated. Since the singularity is, at least according to classical theory, confined to a single point, this wouldn't be breakable.

If the singularity is actually not a singularity but is smeared out somehow on a quantum level, then might cosmological expansion be able to rip it open? Possibly, but physics is nowhere near ready to describe such an event!
