Black hole munched galactic leftovers, spewed stars, burped


If you look carefully at ours over its history, the Milky Way isn't too safe a place for life. Not long-term and not globally. Certainly the big shiny Centre isn't hospitable and almost every star much larger than Sol is too burny and too short-lived to have nice vacation homes around it. Red dwarves, which are 70-80% of all stars are probably not burny enough though they do have the advantage of living just about forever.

Life is probably extremely rare in the cosmos.

I wouldn't be astonished were it confined, at least for the last 13 gigayears and maybe some more to come, to one planet.

Or, if Man has his way, to none in the very near future.
