Not at all. Firstly, it is far, far in the future. Secondly, it is unlikely to have any direct effect on the Earth, othere than producing a more interesting night sky.

- Sure would be interesting to be here when it happens to watch it.

Well... it's predicted to happen in about 3 billion years, and humanity's only existed for about 200 thousand year. I think it's safe to say that we have other problems to worry about in the meantime. One of the indeterminate aspects of the Andromeda Galaxy's approach is its tangential velocity (a doppler shift cannot measure that), and it's too far away to get a good approximation (the distance scales would imply that a very "small" tangential velocity would still yield a miss). Just in case, I think the EU space program sent a probe which might give some useful information at some point in the future.

- Thanks. Great answer. Indded, we do have bigger fish to fry for the time being.

- I would love to be able to go into suspended animation and pop out just in time to watch.

- It would be quite a spectacle alright to look up one night and see it real close after all the stars in the sky at night are all in our own galaxy that just gives a tiny insight to how big this universe is, pretty amazing if you ask me! :)

I am shocked, SHOCKED at the caviler attitude being shown towards future generations. I guess this is just another liberal stick-it-to-the-children scheme for a generation TOO SELFISH to do something about the coming disaster of galactic proportions. The science is solid, people!
.
Three billion years will be over before you know it and then the bill comes due.
.
People like Im Alec are OBVIOUSLY in the pay of Andromedan special interest groups: their science is corrupted by money.
.
If we don't act now, future generations will perish! Do it for...the children.

- Exactly. So get your galactic collision insurance orders in to me pronto, people. Only $99 a month and you're completely protected.

- Good point. We will probably beat the great collision by billions of years.

Why would it? Its supposed to happen billions of years from now. None of us will be here to even care.

No. Most of each galaxy is actually empty space, so nothing will truly "collide."
Comments
- The best guess is that after a few million years of the galactic arms interacting and disrupting each other's mothin through gravitational effects, the black holes at the core of each galaxy will merge into one massive black hole.

Not in the slightest - I learned a long time ago to worry about things like that, over which I can have no control, is complete waste of energy.

It doesn't really worry me.
We will succeed in destroying our Earth making it uninhabitable long before the Galaxies collide.

- That may well be so. Thanks.

- The time-lapse version would probably be a lot more fun to watch. Real time would be dramatic up close, but at our distance, it'd be like watching paint dry.

When will the Andromeda Galaxy collide with the Milky Way?

The Andromeda galaxy and the Milky Way are rushing toward each other at a velocity of 130 km/s (or, 300,000 mph!). We will collide in about 60 billion years. Andromeda is about one and a half times larger in diameter and in mass than our Milky Way. Des

I've seen pictures of the Milky Way Galaxy from the outside. How is that done if where we live is within this galaxy?

Why do astronomers say that the Milky Way and Andromeda Galaxy are supposed to collide, Then they also say that they are moving away from each other (which is proven by its redshift).

Could a Dark matter "wrecking ball" explain the odd tilt and wealth of new stars in our part of the Milky Way Galaxy? See LINK:
