Turn Right! Turn Left!

If you're driving on a two lane highway and a head-on collision seems imminent, you should turn right. This probably doesn't work in England.

Phil Plait of Bad Astronomy tells us that the Andromeda Galaxy is on a collision course with our Milky Way Galaxy [Hold on tight: in 4 billion years, we’re due for a galactic collision!]. What should we do? We don't know whether the Andromedons drive on the right side of the road or the left. Which way should we turn to avoid the collision?

  1. FWIW:
    If anyone read Doc Smith's "Lensman" series of sci-fi books from the old days, they'll remember perhaps that it was just such a collision between (oppositely) galaxies that made our modern galaxy variable enough to have life, and ultimately intelligent life, in it.

    So the only question is, are were Arisians or Eddorians??!?!
