Can black holes be disintegrated from a sufficiently powerful explosion?

[mrspeedybob]

I vaguely remember a pop-sci bit a while back talking about creating baby universes in a lab by pinching off bits of space which would then be separate from our universe and expand in their own big bang. Something like this http://www.npr.org/templates/story/story.php?storyId=6545246

I have no idea what the details are but someone more familiar with this idea might chime in. Would it be possible to pinch off a volume of space containing a black hole so that the black hole no longer exists in out universe, but in its own new universe? It may not technically be disintegration as the OP was asking about the effect is the same, the BH no longer exists, at least in our universe.

Wouldn't a faster spinning black hole evaporate SLIGHTLY faster due to hawking radiation getting caught up in the polar jets? I could he wrong but I thought faster spinning black holes have larger jets which help the accretion disk slow enough so more particles can be absorbed. The same process could help to throw away hawking radiation so that less of it was reabsorbed.

According to a number of sources, spinning (and charge) actually reduces HR though for it to reduce significantly, the black hole would have to be very near maximal (i.e. a/M=1).

Even if you could somehow blow apart a black hole, which seems impossible because trying to do so would just make the black hole larger, it would break into smaller black holes, which could merge back into the original. Nothing changed.

what effect would a supernova blast have if it were within a light year distance of a black hole? we shall never know but the math I'm sure would boil it down to the dreadful singulairity!

Not much. It might mess with an accretion disk if there was one around the black hole, but that's about it. Light that entered the event horizon would be gone and add to the mass of the black hole just like what happens to all light that enters the EH.
