I never saw into darkness - did they get rid of that pesky black hole in our solar system that wound up causing no problems whatsoever?
Since that particular black hole only had the mass of the Narata, it wouldn't cause any gravitational problems for the solar system unless you were right next to it. And then a few hours later it would have detonated due to Hawking evaporation and disappeared. In fact, we have to invoke a little bit of technobabble to even explain why it was a problem for the Enterprise; we have to presume that black holes created with red matter affect objects with residual warp fields dramatically different than normal objects. Otherwise the Narata would have just been absorbed by the red matter black hole and then basically vanished without a visible trace, only to explode the next day in a burst of gamma rays.
In fact, the science-based version of that scene might have been even more interesting. The Narata gets absorbed into the red matter black hole, getting crushed into a micro black hole. Everyone relaxes. Then Spock says something like "Captain, we have to leave immediately" but the warp core is damaged and they can't go to warp so they have to leave much more slowly on impulse power. Because not all of the mass of the Narata fell into the black hole its Hawking lifetime is only minutes, not hours, and as the Enterprise pushes their impulse engines to the limit the Narata's black hole detonates behind them. As it does, Scotty gets the warp engines back just long enough for them to jump to a safe distance.
Hmm. If they did that, they would have been accused of stealing from Wrath of Khan. Ironic.
