Wow i had no idea that the milky way (our galaxy) and Andromeda (our nearest galaxy) are actually on a collision course to smash into each other (I was always taught that post big bang everything is expanding and spreading out).
Oh and just in case we miss (btw we wont because gravity will loop back whatever gets missed on the first collision pass and sort of begin a death spiral), whatever mess is left over is on course for a collision with the even bigger Virgo supercluster a little while after that.
Cheers,
Dean
