There is a new substantiated hypothesis that the universe is now expanding and contracting at the same time (here we go: nasha-vselennaia.ru/?p=10056) .
We think that some galaxies are moving away from us and some are approaching. The Andromeda is approaching to us with high speed (almost with the speed of light), but it falls into the black hole, at the center of which is our galaxy, the Milky Way.
Because of the great gravitational force between our galaxy and Andromeda, there is gravitational compression of time around us. That is, the time passes slowly around us, and it seems to us that Andromeda is approaching us slowly.
The closer it comes to us, the more will be the gravitational force and the time will slow down. We would think that the Andromeda is braking, slowing its approach, but it is actually approaching us almost at the speed of light.
We have nothing to be afraid of. According to our time, it needs billions of years to collide with our galaxy. If we really live in four-dimensional space, there is nothing surprising.

How long to travel to Andromeda galaxy?
The Andromeda Galaxy is about 2.5 million light years away. How long it would take to get their depends on how fast you go, but at the speed of light it would take 2.5 millions years.
How long does it take the milky way galaxy to revolve around the sun?
It doesn't. The Milky Way galaxy is 100,000-120,000 light-years in diameter. The Sun's mass is nowhere near large enough to make the entire galaxy revolve around itself. The Milky Way appears to revolve around us because of our position on Earth. The Earth spins incredibly fast, and is moving much faster than the sun, so therefore the Sun also appears to be rotating around us. However, the Sun orbits the Galactic core, once every (roughly) 226 million years.
How many Galaxies in Milky way?
one million 250 thousand light years away...says buzz lightyear
How fast is the solar system spinning?
The solar system - which includes the sun - is spinning around the center of the Milky Way galaxy. It takes the solar system (or anything else in it's approximate place in the Orion Arm) about 225,000 - 250,000 years to make one complete revolution of the center of the galaxy. I'm afraid I can't break that down into MPH for you though.
How fast are you moving in space?
Just sitting still you are actually moving quite fast through space. The Earth's in its journey around the Sun moves a little under 67,000 mph - about 18.5 miles per second. But our Solar system is also in orbit around the galactic center - at about 143 miles per second. Our Milky Way is also in motion about a common center of gravity of a group of galaxies - the Local Cluster - and that cluster also is in motion - which adds a speed of about 372 miles per second.
How fast does light travel from the Milky Way galaxy to the Andromeda galaxy?
299792.458 kilometres per second
How fast is the milky way galaxy moving away from us?
We are part of the milky way galaxy, so we are moving with it.
How fast is your Milky Way galaxy moving around the local group of galaxies?
300 km/s Edit: I've seen that estimate, but it's not straightforward. It's not like finding how fast the Earth orbits the Sun, for example. For one thing the largest galaxy, called Andromeda, is moving towards Earth.
How fast is the cigar galaxy moving?
Relative to what? From the Milky Way Galaxy it is receding at about 203 km/s
How long to travel to Andromeda galaxy?
The Andromeda Galaxy is about 2.5 million light years away. How long it would take to get their depends on how fast you go, but at the speed of light it would take 2.5 millions years.
What object comes in a coulsion collision with the milky way?
Probably many objects will collide with our Milky Way. One that is fairly well-known is M31 (the Andromeda Galaxy), which seems to be heading directly towards us, and MIGHT collide with our galaxy in 2-3 billion years. However, it is not yet perfectly clear how fast it is moving "sideways", so it may actually miss our galaxy. On the other hand, collisions between galaxies are fairly common events.
How do you see the Milky Way when you are in it?
How do you see a forest when you are in it? What you see are lots of trees. The stars of the Milky Way are like the trees of a forest, scattered very thin. The stars cluster close together at the galactic core, but are arranged in radial arms out where we are. The stars extend some 25,000 light years beyond us to the galactic rim, such that the diameter of our galaxy spans roughly 100,000 light years. A light year is the distance light (which is REALLY fast) travels in one earth year. So the diameter of the galaxy is, therefore, quite large. We cannot see galaxies through the center of our galaxy--their light is blocked by the stars and dust of our galaxy. We can gaze up through the plane of our galaxy, however, at Andromeda--our sister galaxy, and at billions of other galaxies beyond, above and below the Milky Way, and beyond in all directions, stretching out across billions (thousands of millions) of light years.
Are there any probes in the Andromeda Galaxy?
No human probes, no. The Andromeda Galaxy is simply too far away. It is about 2.5 million light years away, meaning that even at the speed of light it would take 2.5 million years to reach it, and no manmade probe can travel anywhere near that fast. Currently the furthest man-made probe is about 16 light ours from Earth, and it took nearly 35 years to get that far. Though technically we have no way of knowing if there is intelligent life somehwere in the Andromeda Galaxy that might be exploring their own solar system with probes.
Why is the light from Andromeda 2.5 million years old?
That means that M31 (the Andromeda Galaxy) is at a distance of about 2.5 million light-years, and that it takes the light 2.5 million years to get here. Light moves quickly, but not instantaneously.
How long does it take our solar system to orbit the milky way how fast does it travel?
It takes approximately 230 million years for the solar system to orbit our galaxy at a speed of about 828,000kph (515,000 mph)
How fast is the milky way galaxy's local cluster moving through the universe?
Compared to what reference point? A velocity of some object should always be indicated relative to some other object.
Milky way galaxy why is it named that?
because in Greek mythology Hera was tricked into nursing one of Zeus's kids and when she found out she pulled the kid away so fast that some extra milk poured out -- that is what they thought it looked like so then astronomers added way and galaxy
