`Scott Very nice post I agree with it I never started this post with the meaning that stars had to hit one another,for that has to be a very rare event. Since I am always bringing in gravity to evolve all that is I have to consider these two galaxies have massive black holes and that could be the big rub. All my pictures in my universe picture scrape book were taken by the Hubble. I know shock wave is used to describe the aftermath of a supernova explosion but looking at the Cartwheel galaxy that word shock wave jumped into my mind. Scott what would have been a better word? The right terminology can be tricky. I find galaxies colliding very interesting. With billions and billions of large galaxies it can not be all that rare. If you have more information on them please post. Your virtual friend Bert PS good reason for us being friends Scott is we both love astronomy Right Painius Might recommend a book I have been reading called "What if the Moon Didn't Exist" by Neil F. Comins. It deals with quite a few "What ifs", not just the one that is the title of the book. One of those is what would happen if a massive star came close to us (which would address one of the pieces of thread attached to this one). Obviously, this scenario would apply to a star in our galaxy coming close to us or a star from another galaxy passing through our own coming close to us (this latter scenario being a more likely scenario than the former). I would provide more details but I recently brought most of my reference material from my office to my house and it is boxed up either in my garage or my den. But, I think if all of the commentators of this thread could hunt down a copy, we would collectively be in a position to address some of the questions this thread has read. |

Cactus saul I cant argue how Andromeda and Milky Way will hit. Since you feel head on is wrong give me your reason for that Bert Since we see M31 nearly edge on, it is quite likely, barring some external force to rotate it, to hit us nearly edge on. Find an image of the entire Milky Way (the band, not the galaxy) and locate within that image Andromeda and the angle it makes with the plain of our galaxy. That may give you some idea of the angle of "attack" we may be subjected to. |

Scott What ifs have to be the best term for starting up ideas on the
universe events that we can not see,but give our brains a chance to imagine(day dream about) Such as the size and density of a star coming to close to our solar system could create havoc. Reality is have done very little reading lately.but5 will try to read that book since it was recommended by you. Bert |

Scott angle of attack of one galaxy hitting another makes for great
interest,and great pictures taken by the Hubble. As I am typing this I am looking at NGC 2207 colliding with a much smaller galaxy IC 2163. I see both galaxies head on. I can see gas ripped from the smaller galaxy,and stretched into a long stream of celestial stuff. Well Scott glad you are back That poster that claimed he liked out posts when we argued over the years might not like us in agreement as much,but your disagreeing with me was much fun. It never ever stopped me from having great respect for your knowledge Bert |

The two galaxies aren't oriented face on, BEERTbrain! lmao!

Define tidal radius first, BradBoi! lmfjao!

The color doesn't change, BEERTbrain, it's the lines in the spectra
which shift more and more to the red. It's NOT a color change. Saul Levy On Sun, 10 Aug 2008 07:03:41 -0400, (G=EMC^2 Glazier) wrote: Timberhead Further out we see the redder and redder it gets.
