Its the closest galaxy to us. Do you think it might strip away some of the mystery surrounding dark matter? Gravity of dark matter is believed to hold galaxies together. What's your belief? The collision might take place or it will travel around us a few times before colliding. This is centuries away.

They are expected to collide, but not for a very long time. Even so, it probably would not be much of a demonstration of dark matter interaction. That has only been observed once, in the Bullet Cluster of galaxies (containing thousands of galaxies, not two in total). The Bullet Cluster collision is the most energetic event in the known universe since the Big Bang -- which gives you an idea of the energies required.

The rate at which galaxies are moving apart grows as they are farther apart. So distant galaxies are moving away faster than closer ones. But, for the close ones, the gravitational attraction between the two galaxies can overwhelm this tendency to move apart: both because the expansion isn't so large and because the gravity is larger. The galaxy that is going to collide with ours is the Andromeda Spiral galaxy. The predicted time for the collision is about 5 billion years from now. Even when they do collide, the individual stars won't likely collide: they are just too far apart from each other. However, the dust and gasses will condense and new stars will be formed. We see this happening in other places right now. Look on the web for the 'Antennae galaxies'.

Eventually all things will either collide or seperate beyond anything we could attempt to comprehend or even suppose to imagine.
I am likeing the spread to a point then Gravity Flux kicks in and reverses the process. That would be fun to watch. Our universe into a nothing that explodes in another time and space to become a something.

The universe is expanding so these galaxies are moving away from each other. Eventually it is expected that in a few million years gravitational pull will stop the expansion and the universe will collapse into itself creating a huge black hole. They will collide at that point.

Some scientists think that it will collide, but the closest time I've heard is at least a few tens of millions of years from now.

I don't think we will because astronomers have observed all galaxies moving outward and moving farther and farther apart from each other.
Ps
We are sooo far away from the Andremeda Galaxy

I believe we will learn more about what hold galaxies together well before that happens.

Yes, in about 3 billion years, so don't worry about our sun running out of fuel in 5 billion!
