Title: Is the Milky Way a collided galaxy?
Post by: Naru523 on December 26, 2009, 09:04:21 PM

If you dont get hat Im saying, I mean that the Milky Way was born by two galaxies colliding. Is this true or false?

False. The milky way would be irregular or elliptical, not a barred spiral.

It can re-shape!

Was that necessary?

I think I read or watched something saying that the Milky Way could be a Galaxy with a collision in it's past.

False is the answer.

No, it can't. Once an ellipse is formed, it cannot change.

the answer to your question as I see it is iether yes or no, depending on what you mean.  If you mean that it was formed from one giant collision then I think its possible but unlikely since as deoxy99 said we aren't an elliptical galaxy, but all galaxies are believed to be built from a small core galaxy at the beginning that eats and joins with others to form the modern galaxy, in fact the milky way is currently eating several dwarf galaxies.

Then I wonder how MW and M 31 (Andromeda) got two black holes...
