Lol... funny... but collisions of galaxies is not a catostrophic event... as a matter of fact no stars will probably colide even when the galaxies "colide" because the stars are lightyears away from each other. The only thing it could maybe do is throw a planet or 2 out of orbit and make all the stars change positions instead of a neat little spin. The chances of a collision with our planet in a galaxy collision is (laugh) astronomical. http://www.astronomynotes.com/galaxy/s10.htm Check it yourself
