I watched an animation of this collision earlier, and would like to put fourth the symbolism I saw in how this may work. The centre of these two galaxy's is the scorce for eaches gravity. It's what holds them together. As they approach each other, and waltz, outer pieces are thrown out, cast away. Any thing close enough to scorce stays safely put and eventually merges into one. Many coincidences, selestial, heavenly, earthly and bodily suggest nature repeats itself on many levels. Noah had to build an ark. Could it have been arc?= spark, connection. Connecting to points in space and time. When I visualise what would happen energetically if something like niburu was to pass though our solar system, I get the same sort of image. Then put this in with the rapture, you can see how it's possible for people/planets, to just dissapear. they can get flung of/ out. Cast away of saved? Dunno! I'm not religious, just see historicle stories in everything of late.

From what ive heard there is so much empty space in a galaxy that there is very little chance that celestial bodys will collide. but im sure a few will but chances are we will b fine.
