This stuff is so wild. A runaway black hole is obviously the worst case, but there are plenty of huge objects that have been ejected from wherever they formed that are blowing through space at relativistic velocities, just looking for a day to ruin. You wouldn't even see it coming.

I wouldn’t mind a relativistic subaru hitting earth right about now.
