I think it's very cool to see what will happen when the Milky Way and Andromeda finally collide. It's like getting a preview of a movie we'll never see.
A movie five billion years from now if the Earth makes it to that point.
 
*sigh*

this is why we can't have nice things

This news makes me upset. I know it's a harsh environment and we aren't really able to control things, but dang. At least give us a little time to get some good data. Unfortunately, this is something we'll have to deal with until we can invent Star Trek style shields.

I don't know that inventing the shields would be that difficult. We already have the theory on how to do warp travel as well but we don't have a source of energy that can do it yet.

Another reason why getting fusion to work is so important
 
This is something that I've wondered about

I'm sure galaxies colliding/merging is a very slow process, but if it was happening right now, how would we here on Earth perceive it?

Just the stars being different or other effects?
We won't be around when it happens, but if we were, it takes the Milky Way something like 200 million years to spin one time. Assumining we were on the outside edge of the collision, it would take a long time for us to see the effects or be in danger. But, like Tapxe mentioned, we won't be around when that happens.

I'd percieve it as "well, it was nice knowing ya, see ya on the other side!".

There is so much space between the stars that actual collisions would be rare until each of the galactic centers were really close to each other. Gravitational forces would likely send some stars spinning out of the combined galaxies to wander until they encountered another gravitational force strong enough to draw them in. The amount of space between large objects in the universe is astounding.

The Earth would be, more than likely, a barren rock rock when the Milky Way collides with another galaxy. Hell, Europa would probably be the most habituated planet in our solar system by then.
 
The light from these galaxies that are 13 billion light years away traveled to us in a straight line, not blocked by other things. With the number of galaxies in just these few pictures, which is a tiny speck of the universe, the amount of open space is mind boggling.

There is probably more empty space in between galaxies than there are galaxies. And there are billions of galaxies. The visible to the naked eye night sky has more stars than grains of sand on all the beaches....and that's just what we can see with the naked eye.
