Is our universe expanding in a linear fashion or something else
This weeks tricky question. Note I have no idea of an answer hence asking it as it has puzzled me on and off for a few years now.
You may have seen the recent Stuff article about pictures of two galaxies colliding ? And the mention that Andromeda and our Milky Way galaxies will collide in about 4 billion years ?
I though that the universe was expanding which implies straight paths. If this was correct then none of these galaxies would ever get closer to each other. So how come they will, and others are, colliding as this implies some sideways movement ?? (There are a few other qualifications here but lets run with the question as stated).

Response to regifting presents
My mind tends to wander:
I do not see any problem with regifting it back to the person who gave it, they obviously liked it. In fact, that might work out well as you buy the present you want, then gift it to someone you know who will gift it back.
Perfect, no decision needs to be made about Xmas presents
