How can galaxies collide if they are moving away from each other?

Not all galaxies are moving away from each other. In fact the galaxy Andromeda is moving toward the Milky Way and they will eventually collide, because Andromeda is so much bigger than our Milky Way it will preatty much eat us and ruin our galaxy. Good news: it won't happen in our life time, and we are the 2nd largest gallaxy in the Local Group and no other (known) gallaxies are moving toward us.

∙ 14y agoYes our galaxy moves. It spins through space around its center which contains a massive black hole, it moves in relation to our local group of galaxies, and it moves relative to the distant galaxies as well. If you stop and think about it, there is absolutely nothing anywhere that can be said to be motionless.

∙ 12y agoMost galaxies are moving away from one another, and this is, according to the theory, a direct result of the ongoing expansion of the universe from the time of the initial expansion, the so-called big bang. The reason some galaxies are moving toward one another (and routinely colliding, actually) is because some galaxies are moving in groups or clusters. They have come close enough together that their mutual gravity keeps them together, orbiting around one another or moving in other ways. The Andromeda Galaxy, one of the closer star groups to the Milky Way, is on a collision course with the Milky Way. If you are around in about 5 billion years, you may get to see the night sky change completely as the chaos of the collision re-arranges all the stars in both galaxies.

∙ 13y agoGalaxies are mostly moving away from each other, due to the continual expansion of the universe from the Big Bang. Not all galaxies are; for example, the Andromeda Galaxy is approaching our Milky Way, and they will probably collide and merge in about 4 billion years.
The further away a galaxy is, the faster it seems to be moving away from us. This is one part of the data on which Edwin Hubble's idea of an expanding universe was based.

∙ 12y agoYes, in my universe all of the galaxies are moving relative to each other.

What does red shift tell us about other galaxies?
It tells us that most galaxies are moving away from us.
What can astronomers infer from the fact that other galaxies are moving away from ours?
You can infer that the universe is getting larger.
Galaxies that are moving away from Earth are .?
Most of them. except for Andromeda galaxy which is coming towards us - our Milky Way galaxy and they both will collide in 3-4 billion years(Repetition of ''Big Bang'')
What is the significance of red shift galaxies?
It means they are moving away from us.
What is the general relationship between a galaxy's distance from earth and its speed?
were part of a galaxy?!! _____________________________ Yes, we are. It's part of the Earthling's Handbook; didn't you get a copy? The majority of other galaxies are moving away from us. (One notable exception is the Andromeda Galaxy; our Milky Way will probably collide with Andromeda in about 4 billion years or so.) Curiously, the farther away from us a galaxy is, the faster it seems to be receding! The relationship is called "Hubble's Law" for the man who figured it out, Edwin Hubble. (The Hubble Space Telescope is named in his honor.)
Are all galaxies moving away from ours because your galaxy is at the center of the universe?
Other galaxies are moving away because the universe is expanding, but we are not at the centre of the universe.
Are there planets inside of galaxies?
Yes. Our own solar system is part of the Milky Way galaxy. Thousands of other systems with planets have been discovered in our galaxy. The number of planets in our galaxy alone prbably numbers in the billions.
Are galaxys moving away from each other which means the universe is contracting?
No.More specifically:Not all galaxies are moving away from each other. The Milky Way and Andromeda galaxies are moving towards each other (and at a pretty good clip, too: about 300 km/s). The entire "local group" of galaxies is moving in the general direction of something called the "Shapley Supercluster".Very distant galaxies do tend to be moving away from each other, but that means the universe is expanding, not contracting.
What does red shift tell us about other galaxies?
It tells us that most galaxies are moving away from us.
In which direction are mostly all galaxies moving?
Actually, most galaxies are all moving away from all other galaxies, not just from ours. The exception is the Andromeda galaxy, with which the Milky Way is on a collision course.
How are galaxies moving today?
galaxies are movign further away from eachother
How many galaxies are approaching milky way galaxy and how many are moving away related to the cosmological red shift?
Most galaxies are moving away from us. Only a few galaxies, which are nearby, are moving towards us.
What does the big bang theory say about the movement of galaxies?
The Big bang theory states that the galaxies are in fact moving away from each other
In which direction are nearby all galaxies moving relative to earth?
Nearly all galaxies are moving away from our galaxie and planet.
If light from galaxies is redshifted what can astronomers conclude about galaxies?
That the galaxy is moving away from us.
Which has a higher frequency a star moving away from earth or towards earth?
I would think that current evidence suggests that the stars moving away from earth, some of them in far distant galaxies moving at unimaginably high speeds, are going much faster than stars moving toward us. The entire Andromeda galaxy is moving toward us and will collide with us in roughly 5 billion years, and it is not moving anywhere near as fast as the distant retreating galaxies.
What direction are observed galaxies moving from your galaxy?
Away.
