Probably the biggest problem facing a civilization in a colliding pair of galaxies would be increased radiation from the burst of star formation. Depending on whether or not they were in the wrong spot, they could find themselves and their planet sterilized.

The chances of that happening are actually fairly low though. The vast distances between stars is mind boggling. I do some mind-boggling of kids when I demonstrate solar system distances.

Everyone was so hyped up about the LHC creating a micro black whole and destroying life as we know it, and look what happened, the thing broke down.
Don't believe what everyone says.

I've read articles and seen on the History Channel that there could be moving black holes in the universe that could one day enter our Solar System and cause chaos.
I don't really believe it but.
A black hole is created when a large star (much bigger than our Sun) finally reaches the end of its life cycle and collapses in on itself and explodes, leaving behind a black hole.
The thing is, black holes aren't forever, because they gradually diminish away due to 'Hawkings Radiation"

I have also read that in about 2 billion years or so from now, the Milky Way and Andromeda galaxy will collide and become one, but scientists think that when the two center Super-Massive black holes also have a run in with each other, it could imbalance the entire galaxy, causing many problems.

It is the mini-"Black Holes" that I said are common. The one I was refering to was about 2 feet wide. The anouncer on the NASA vidio said that the objects they saw where much bigger. They did not call them "Black Holes," they fit the dicription of "Black Holes."

I don't think the "Black Holes" in the center of the galixies are going to brack lose and go brizerk. The Universe is in balance. Asteroids shift when a large object passes them but I think that the solar system is running out of large asteroids.

You appear to be very, very confused.

Please do not simply assert. Back up your statements. Where can I read about how black holes are "quite common in orbit around the Earth." or that they have been photographed from the space station? Which NASA documentaries show them?

The galactic black hole is about 4 billion solar masses. It is more fair to say that the galaxy orbits around the black hole than that the stars are 'holding it in'.

I saw an object that astronomers call a mini-"Black-Hole", it collided with a wall several times just bouncing off each time and then flew into space. They are quite common in orbit around the Earth. They have been photographed from the space station. You can see them on NASA documentaries. They are rodioactive and it is not safe to get within 10 feet of them. The "Black Hole" in the center of the Galixy can't get out, the stars are holding it in.
