The gravitational binding force of the Local Group prevents the Milky Way and Andromeda from receding from each other with the Hubble expansion. Their paths are actually converging and in about four billion years they will collide and merge.
Ok, this really sounds like the space is expanding, even where there is matter, but everything is being pulled together faster than the expansion. This is going to bother me and keep me up at night, isn't it?
