Hi,

I heard something kinda interesting on Science Friday on OPB radio today and thought I'd share. They were talking with a Harvard astronomy professor about the recent maping of the universe that they have been doing and at the end of the talk the professor mentioned that we are falling towards the andromeda galaxy (or vice-versa) and I am wondering if it would discount the previous theories that I've heard that in the past we have collided with the andromeda galaxy. I was under the impression that this was a prevalent theory and if it is no longer valid or if (over a very long period of time) our galaxy and that of andromeda can be expected to collide a number of times. Also if the second is the case our galaxy might well be quite strange looking (perhaps this is an element considered when models for galaxy evolution are formed?). Anyway I thought I'd send this out and give you all something to think about.
