Collision of Galaxies scenarios
I am trying to get a sense of the utter chaos that could result in
such an event, say if Andromeda were to merge with Milkyway Lets define on a scale of 1-10 (10) being if a Star a few solar masses were to directly collide with our dear Sun.. or If our solar system were dragged into a blackhole in the Andromeda measuring a few hundred thousand solar masses.. I guess the latter would be almost like being picked clean.. (1) being a star coming in close enough to form a binary system with our Sun.. with an orbit far greater than the outer reaches of our SOlar system I am curious what are the scenarios out there.. can we ever hope to survive such a merger of the two galaxies? Although at first glance I am tempted to say that we are doomed, somehow the distances between celestial entities is so great within each galaxy that I am also wondering if there is a strong chance that we can survive a merger.. I also would like to know other scenarios that could occur in a merger.. If a star were to come close enough is there a change for the star to pull away some of the planets that are orbiting the Sun?? I am also curious how long it takes for Andromeda and Milkyway to merge assuming that we start timing the moment the two are close enough that contact is first established in the outer reaches |

Collision of Galaxies scenarios
As galaxies approach each other in the process of a merger, a number
of scenarios could arise 1. Normal vector to the rotating galaxies facing the same direction 2. Normal vector to the rotating galaxies facing the opposite direction 3. Normal vector to the rotating galaxies perpendicular to each other (like a bevel gear or a worm gear configuration) I am curious how the resulting galaxy would differ in shape, chaos (or entropy) from the rest for each of the above cases. Also in "2" above, the angular momentum would be drastically reduced, Wouldnt this cause a collapse of the resulting galaxy into itself to form a super massive blackhole due to gravitational forces within in time. Or can the resulting galaxy stabilize with stars and matter within rotating in opposite directions. (Raj Diva) wrote in message ...
