There are very real limits to the volume of the galaxy which is within our reach, because of the expansion of the universe. After a certain amount of time, the most distant galaxies will expand so far away from us that they will pass beyond our event horizon; this effect will get closer and closer to Earth until we can only reach the gravitationally-bound galaxies of the Local Group.
Unfortunately I can't remember the exact figures for any of this.
