2012 ¿End of the world?

[spukrian]

First of all the Earth won't end because of the "collision" between the Milky Way and Andromeda. its like you are trying to collide two clouds and see how many water drops will crash into each other... which are almost none. although in the far future. the Milky way seem to be crashing into Andromeda. not even single star will ever collide whit another on that event... galaxies are incredibly huge but there is and incredibly immense empty space in it as well. makeing any effects caused on this collision to be almost non existent... the worst thing that might happen is for the solar system to be thrown away off the galaxy... which again won't really affect the solar system itself other then were it will stand.

Are you sure? Stars have strong gravitational pull, I'd say the probability of things colliding when the two galaxies meet is high. A better analogy would be a cloud of magnetic iron dust colliding with another magnetic iron dust cloud.
