Why is the Milky way running towards its destination at a speed of 2 million kilometers per hour so far apart?

At the level of astronomy, mankind has a common understanding that the most subversive discovery is the big bang. What is the big bang? In fact, before we discuss its definition, we may still need to know a point of view – scientists generally believe that the universe is eternal, at the same time, the universe has no beginning or end, and the universe will not change with the passage of time.

Of course, Newton and Einstein also agree with this view. They both think that the universe should be infinite, and there is a center everywhere, and there is a balance everywhere. Then another scientist put forward a different view, that is, Hubble. Hubble found that most of the galaxies outside the original Milky way are far away from us, and has a very interesting point of view. If these galaxies are farther away from us, the faster they will go to us. Therefore, Hubble infers that the universe is expanding according to time.

So according to Hubble’s discovery, scientists began to use reverse thinking to reason, so the universe might have been a very small base point in the early days, and then it came into being as it is now because of the big bang. Of course, these are just their guesses. Later on, Gamov established some theories – they think that the Big Bang will leave some residual heat, and this energy is the microwave background radiation, which has spread all over the universe and the world.


Until now, astronomers have found that what they actually observed is consistent with what the two scientists said. At the same time, they have also found that microwave radiation exists all day. Therefore, these theories together constitute the key evidence of the big bang.

So what does this have to do with the fact that celestial bodies are far away from us? And why does it happen that our galaxy is heading for a constellation?

This galaxy is actually Andromeda, so the Milky way is actually in the local group. Of course, there are many other galaxies in this group. It’s all due to gravity. Because of gravity, it will lead to a collision with the largest Galaxy in this cluster, and eventually a merger.

So now our galaxy is moving at 110 kilometers per second. Close to Andromeda. So when the reference object turns into Andromeda galaxy, it means that all of us are moving towards it at the speed of 110 kilometers per second, and the whole process is dominated by all kinds of gravitation.


In fact, mass is the most important thing in the universe. Now our galaxy is in the Virgo supercluster. And in this cluster, there’s something called a giant gravitation. It’s massive, and it’s at least 150 million light-years away from the Milky way. And this giant galaxy is in the local Galaxy Group, so the local Galaxy Group is a supercluster, and it is also in it. The center is called the Rania Kea supercluster, and the most important one is called the giant attractor.

Of course, the mass of this thing has reached the 16th power of 5.4 × 10 of the sun. So it means that because of its existence, everything in the galaxy will move towards it. From this we can see that the galaxy will also move towards it, with a speed of 600 kilometers per hour, which means that the speed is 2 million kilometers per hour.

So will one day our galaxy, like Andromeda galaxy, merge with this giant gravitation source due to gravity?


In fact, this is really impossible, because although we human beings see the speed is very fast, if the reference object becomes the universe again, the speed will be too slow. At the same time, the key is that the universe is expanding all the time. If from the micro point of view, the universe is dominated by gravity, then from the macro point of view, the expansion of the universe Sense is further dominating, so whether the galaxy will be attracted to it or not depends on the scale.

However, because the large scale and small scale are defined by human beings, the standard is unified, which is about 100 million light years away, while the Milky way is 150 million light years away

Therefore, the expanding universe is dominated by everything, so the giant gravitation source should be farther and farther away from the galaxy, rather than closer and closer.
