Does it bother anyone else?
I sort of figure we've been around long enough to have encountered and swept up most of that which would get in our way, that we have guardian planets, with moons, which has cleaned up the neighborhood pretty darned well. Sort of safe.

And then things like this come along, out of our blue, never considered, and could be flooding the area. One big jostle from a galaxy or cloud could send it scooting our way. Now something 3 to 10 times the size of Jupiter is going to be hard to corral and control, would raise all kinds of hell if it got near us, let along transited the Solar System.

Maybe they should just stop looking, or reporting and let me go back to the quiet peace of my childhood where there was empty space out there with nothing lurking to clobber me when my back is turned.
