Hey, I think you're being a panic-monger!
Are you trying to get a budget allocation for saving the galaxy? :)
The distances are so vast that it is most unlikely that stars or
planets will have close encounters of the catastrophic kind.
"Perhaps even more intriguing is the fact that life on Earth –
whatever it may be – will probably live through and witness the entire
merger over the billion-year dance of the two galaxies, he says. The
reason is that the expected lifetime of our sun is projected to last
another five billion years. Plus, the likelihood of stars and planets
slamming into each other is very low because the distance between them
is so vast. The interaction will be "collision-less," with the most
significant effect involving huge gravitational distortions of the
systems as they coalesce."
