  • so how do you think would large galaxies like the milky way created ? :)

  • There's a lot of ongoing research trying to answer that question, but right now our best model is that after the Big Bang, matter wasn't distributed evenly. The very slightly denser areas attracted other matter to them, and after a while most matter was clumped up into what later became young galaxies.

  • It seems like it would be hard to find a job as an astronomer/physicist/scientist­? Is that true?

    I've always been so interested in astronomy and physics, but don't even know where to start, besides reading books from Stephen Hawking ;)

    Anyone have a suggestion?

  • It's a competitive field, but if you love it, then there's a place for you in it. Best place to start is by taking astronomy and physics classes, and seeing where your interests lead you.

  • I hope the sun doesn't blow up. That would be annoying.

  • This is the first time I have heard of a smaller galaxy already colliding with our own. Very informative and surprising.

  • sure, if they;'re approaching one another and "combine", yes, yes I have!

  • i don't know, a black hole may exist then it will be back to normal again. it is as far as i know. And i haven't heard that a galaxy will collide with the other because galaxies are so far apart from the Milky way. Andromeda is Lightyears away from us. It may be impossible that a galaxy will move closer from ours. I'm only thirteen and that's what i think.:D

  • Well there's a difference between blackholes and super massive black holes that aren in the center of galaxies. The only difference really being size. The blackholes in the center of most "active" galaxies are massive. When galaxies collide the black hole will orbit eachother and the galaxies will sort of spin through each other. On each orbit they will get closer and closer till they collide and become even bigger and the galaxy get bigger and becomes one galaxy with 1 massive black hole.

  • lol a galaxy eats an other galaxy ....never heard that before!

  • If we have a couple of other smaller galaxies colliding with our own is this the reason we have more then one black hole in our galaxy. Does anyone know how many black holes our galaxy has?

  • thank you ..I learn something..

    As stated below; that the first I hear of a small galaxy colliding with ours ( ME TO )

    How come no one talk about this event?
