How close is the library to the quasar, as the stuff the spews out on both sides is what we know as Hawking Radiation. It would have to be far away, as the beams of energy would incinerate the library, if it was too close, as it is very hot. What is inside of it? A huge shield generator, to make it stronger than a titan's?
For the Strange Matter, since atoms are very easy to convert, then it would repeatedly do the same process, making it take a very short time to take over a planet. For space dust, it's everywhere. If a titan is fucked up, then a lot of space dust is fucked up, as well. It takes only an object a half-mile wide in diameter, to effectively affect surrounding objects with the gravitational pull. A size of a titan would pull a hell of a lot of space dust towards it. There are also micrometeorites, which are like meteorites, but too small to be seen by the naked eye, and a danger to astronauts in space. There are a lot of space dust and micro meteors in busy areas, like around a planet, for instance, which is where most battles take place. I bet that there would be debris, from destroyed ships and stuff. That would be also a target. If a capital ship blows up, then there would be a lot of debris, and if Strange Matter is set loose, the entire battlefield would be in danger of being fucked up.
