yes. Total time is about 8 billions years.
from now to complete merging
the Andromeda galaxy is actually moving toward us @
700,000 miles per hour
when we meet. they'll blend into each other, but stars will start to be thrown around wildly, some will crash into each other exploding into gases and the gases will condense in the center of the mess
soon things would settle down.
each galaxy has at least 1 blackhole in it, and when these blackholes meet each other, they will devour one another, causing mass damage to the stars near them.

.
yeah, I'm sure my time estimate was wrong, but watch the video and understand that blackholes ARE REAL!!
we have 2 of them in the center of our galaxy

I believe the latest thinking is that it's an inevitablility that our Galaxy will crash into the Andromeda galaxy in about 3 billion years.
When galaxies collide : http://haydenplanetarium.org/resources/ava/page/index.php?file=G0601andmilwy
We haven't done / don't have enough information to do the specific math yet, but it's more than a little possible that our sun and the more fashionable parts of our solar system could be ejected from the Milky Way or simply endure the crash and become part of the Mikly Way/Andromeda mega-galaxy which will be the end-result of our collision after a few billion years of course based on those timeframes, we will either be long extinct, have evolved into some higher form of creature or otherwise have ourselves distributed across a non-small portion of the galaxy pretty well.
Think of it as a big galactic mashup.

That is expected to happen in billions of years. But even then, galaxies are mostly empty space. The stars in them will just pass by each other without colliding. But their orbits around their individual galactic centers will be disturbed. And dust and gas clouds will merge creating shock waves that will trigger star formation. All this would happen in extreme slow motion from the point of view of a human lifetime, taking many millions of years to happen.

Quite possibe. Happens all the time. Many of the nebulae we've seen in deep space photos are the remnants of galaxy collisions. The results are quite spectacular, but play out over millions of years. There are no galaxies near enough ours to pose any risk to us for many, many billions of years.

damn it every time i have a good all well explained answer its taken guy number 1 has got it right but off on the estimated time period more than the addressed above
except for the black hole thing that is also a maybe not proven yet

yes it is
but it says on wikipedia that even the andromeda galaxy will collide with ours (big crunch) our solar sytem will not be highlly affected

yeah what Mercury2010 posted is what i heard from my astronomy obsessed daddy!!
I cannot wait for this to happen!
