Now there is a cool place for a sci-fi setting: "If most stars in the Galactic centre form with planetary systems, then our simulations indicate that there should be planets in highly eccentric orbits around SgrA*." From (http://arxiv.org/pdf/1201.1446.pdf, "Hypervelocity Planets and Transits Around Hypervelocity Stars", Idan Ginsburg⋆, Abraham Loeb† & Gary A. Wegner‡
Now who needs to read science fiction as long as you can read stuff like this from the Institute of Nuclear Research of the Russian Academy of Science. "Yet, some difficulties (or advantages?) of a life inside Black Holes are worth mentioning, such as a possible causality violation and the growing energy density in the close vicinity of the Cauchy horizon." - really, those are the only difficulties?
A nice find from someone at my former home MPIA. Not only is it metal poor (which means more places for planets), it is also old 12.8Gy (which means more time to evolve something interesting). Lets keep filling in those terms in the Drake equation!
