M31, better known as the Andromeda Galaxy, is predicted to intersect with our own galaxy (The Milky Way) in about 3 billion years. Keep in mind that M31 is currently about 2,500,000 light years away at this point in time.
While the previous comment has a bit of a point in that vast portions of each galaxy are "empty", the gravitational effects, combined with the merging masses of dark matter, will result in a radically different Milky Way than the one we know.
Galaxies merge. The Milky Way is slowly absorbing several "satellite" galaxies even as I type this. Heck, after 13 billion years, the Milky Way is nowhere close to the same galaxy it was when newly-formed.
In any event, I highly doubt any of us will be around to worry about the effects of this merger. 3 billion years is a pretty long time from now.

i'm here to lower back up Morningfox, we aren't sure. people who learn astronomy an prolonged time now and lower back do not stay contemporary and are in line with previous information, with the objective to assert MW is for valuable smaller is faulty. I fairly undergo in innovations examining in the final 3 hundred and sixty 5 days that new information might recommend the MW is as vast or greater advantageous than M31. information greater advantageous than 3 years previous has outlived its shelf existence and might have long gone bitter. there is not any debate that throughout 4 to 5 billion years we will start to merge into one greater advantageous galaxy that would desire to be finished in 6 to 7 billion years....do not lay conscious nights hectic abut that. supply Morningfox the ideal answer and placed this to mattress.

Nature is harmonious in all her workings, and that which is above is as that which is below. Thus also, the Truths which by material Science we investigate, are but special examples of the all-pervading Laws of the Universe. So, within this pure and limpid fluid, lie hidden and unperceived of mortal eyes, the elements bearing the semblance of blood, even as within the heart and brain of the investigator lie concealed the Divine Secrets of the Hidden Knowledge. Yet if the oath be forgotten, and the solemn pledge broken, then that which is secret shall be revealed. LET COME WHAT MUST!

yes it will! but in a long long time it is already moving towards us at a speed of 50000 kms! the galaxy will "mix with the m31 and will form a double galaxy it will be the back to the chaos! (the start of the evolution!

It isn't, and even if it were, there's no real reason to worry. Galaxies are mostly empty space, and the odds of our planet being even indirectly affected by the gravity of passing stars is exceedingly low. The other galaxy will most likely pass through us like we weren't even here. It might be noted that indeed, on average, there isn't much of anything in the galaxy at all.
xholme - decaffe, look into it.

The Andromeda Galaxy is approaching the Sun at about 300 kilometres per second (186 miles/sec.). It is also 2.52 million light year away from us. A light year is 9.46 x 10^15 meters.
Can you do this grade school math now?
