After the Milky Way and the Andromeda Galaxy collided, what would humans do?

When they collide, the black holes at the center of the Milky Way and Andromeda galaxies merge together to become larger black holes, with planets and stars changing their orbits due to gravity. The Earth will also collide with other planets at that time, and humanity will have to find a way to find a suitable planet for itself.

It is very likely that humanity will perish, because if these two galaxies collide, it will definitely be extremely harmful, resulting in the inability of human beings to survive normally.

This question is about the collision of the Milky Way, so let's first understand what the Milky Way is. The Milky Way is a type of celestial system, which refers to a system composed of huge star systems like the solar system and interstellar dust. Generally, the Milky Way is classified into 4 categories: Spiral Milky Way, Lens Milky Way, Elliptical Milky Way, and Irregular Milky Way, but the Milky Way in the universe is very large in diameter from thousands of light-years to tens of thousands of light-years to hundreds of thousands of light-years, and the number of stars contained in a Milky Way is also very large.

Galaxy. There are many galaxies in the >< universe that are constantly moving, and from Earth, there are both separate and close galaxies. Because the direction of movement of the Milky Way in the universe is different, then it is also possible for the Milky Ways to collide and fuse with each other, and in the process of galactic fusion that the Astronomical Cosmic Telescope has found through a part of the collision and fusion, the gravity of the two galaxies stretches and collides with each other, and the final fusion of the galacies is discharged from a part of the matter, and the scale of the final fusion is very large.

Conflict NGC4038 and NGC4039 Milky Way So, will the galaxy to which our earth belongs conflict with other galaxies? The answer is that the object of the conflict is our neighbor galaxy "fairy galaxy", the fairy galaxy is also a spiral galaxy, larger than the height of our galaxy, the scale is twice that of the galaxy, the distance is 2.54 million light years, and now the speed of the fairy galaxy at 500,000 kilometers per hour is closer to this speed according to our galaxy, the great conflict between the galaxy and the fairy galaxy will occur in 3 billion years.

Fairy GalaxySo, what should we humans do at that time? Life on Earth is undergoing a process of evolution, and it is unknown whether there will be such a species as humans in 3 billion years, and the possibility of extinction is high. Of course, if we assume that human beings existed at that time, there is no need to worry so much, but after three billion years, human science and technology and civilization will reach the level of "galactic civilization", which can cope with the crisis of conflict and integration between galaxies.

According to scientists' hypothesis, the full collision process of the Milky Way and the Fairy Galaxy will last about 1 billion years and will eventually merge into a larger oval galaxy.

Humanity may have no place to live at all, or it may use some kind of high-level technology to avoid the consequences of such a collision, but everything is unknown, because the galaxy is so vast that we can't ** everything happens.

At that time, human beings may have moved to other planets or other galaxies, because now human beings have been exploring other galaxies, so at that time human beings should have implemented self-rescue.

If two galaxies collide, then all human beings may die, because the collision of galaxies will cause a large **, and it is impossible for humans to survive.

If the Milky Way and the Andromeda Galaxy collide with each other, the consequences will be difficult, and humanity will only move to other planets at that time.

Galaxy. So many galaxies in the universe are in constant motion, and from Earth, some galaxies are moving away from us, while others are moving closer to us. Since the direction of movement of different galaxies in the universe is different, it is also possible for galaxies to collide and merge with each other, through astronomical telescopes we have found that some galaxies in the universe are colliding and merging, in the process of fusion, the two galaxies will pull each other due to gravity, collide, some matter is thrown away, and may eventually merge into a larger galaxy.

The NGC 4038 and NGC 4039 galaxies collide with each other.

So, will the Milky Way, where our Earth is located, collide with other galaxies? The answer is yes, the object of the collision is our galaxy neighbor "Andromeda Galaxy", the Andromeda Galaxy is also a spiral galaxy, larger than our Milky Way, about twice the size of the Milky Way, about 2.54 million light-years away from us, the current Andromeda Galaxy is about 500,000 kilometers per hour close to our Milky Way, if you extrapolate at this speed, the Milky Way and the Andromeda Galaxy collision will occur 3 billion years later.

Andromeda Galaxy. So, what should we humans do at that time? We know that life on the earth has an evolutionary process, and it is unknown whether there will be a human species in 3 billion years, and it is very likely that the human species will be extinct by then.

Of course, if we assume that human beings still exist at that time, then we don't have to worry too much, I think that after 3 billion years of development, the level of human science and technology and civilization should have been able to reach the level of "galaxy civilization", and there should be ways to deal with the crisis caused by the collision and fusion of galaxies. According to scientists' calculations, the entire collision process between the Milky Way and the Andromeda Galaxy will last about 1 billion years, and will eventually merge into a much larger elliptical galaxy.

A combination of galaxies in the process of merging (UGC 2369).

As far as I know, don't worry about anything, don't worry about it, because there is no effect on the local space of the Earth. It's like two countries merging and integrating, but your home is still your home, and it's still in that place (solar system), and you can never get out of this place (solar system), and basically nothing from the outside world will fly into this place. So, what are you worried about this merger and collision?

However, as a phenomenon, an event is still worth observing and studying.

What to do? After 4.3 billion years, human beings have evolved into a super super civilization, do whatever you want, find an old bowl to put these two galaxies in, a little salt and vinegar, and a small grinding sesame oil, cool companion, eat! [I want to be quiet] [I want to be quiet] [I want to be quiet] [I want to be quiet] [I want to be quiet] [I want to be quiet] [I want to be quiet].

Scientists have confirmed that the Andromeda Galaxy is speeding towards the Milky Way at a speed of about 120 kilometers per second. The Andromeda Galaxy is located about 2.54 million light-years from Earth and will meet the Milky Way in about 100 million years. When you think about the impact of asteroids on Earth, you think that if galaxies with hundreds of billions of stars collide with each other, it will destroy the sky and the Earth, not to mention the solar system.

The collision between Andromeda and the Milky Way in the future may not be as scary as we think.

Scientists believe that when Andromeda collides with the Milky Way, both the Sun and the Earth are safe. Why? Collisions between galaxies are very common in the universe and are key to the evolution of galaxies.

When we talk about galaxy collisions, this is a bit of an exaggeration. Galaxies don't actually collide, they meet and merge under gravitational pull to form a much larger galaxy. Therefore, the collision between galaxies does not bring destruction but rebirth.

You know, galaxies are made up of a large number of stars. There are hundreds of billions of stars in both the Milky Way and Andromeda. The distance between the stars is very large.

The distance between the stars in the Milky Way is more than 3 light-years.

This is a very large distance. The closest star around the Sun, the constellation Centauri, is also light-years away. How big is this space?

The distance between the Sun and the constellation Centauri is more than 30 million times the diameter of the Sun. That is, if the Sun is shrunk into a coin, then the constellation Centauri is 700 kilometers away.

Look, that's how far apart the stars are! So when Andromeda and the Milky Way collide, they don't actually collide, but they travel through the vast interstellar space, they are pulled back by gravity, they pass through again, they do this many times, and they eventually merge into one much larger galaxy. In this process, the chances of the Sun colliding with another star are very, very small.

The sun and the earth will survive the merger. In any case, that will be 30 or 4 billion years away, when the Earth is too hot for humans to live on. The Andromeda merger of the Milky Way will provide humanity with more habitable planets if they are still around.

Yes. Because the solar system is a member of the Milky Way, and both the Milky Way and the Andromeda Galaxy are very large, I think the solar systems will collide as well.

Collisions in the solar system are also possible. Because there are many planets in the universe that move irregularly, collisions can occur at any time.

The solar system is supposed to collide, because the solar system is in the Milky Way, so the solar system must also collide.

It is very dangerous for humans to have illusions about the collision of Andromeda and the Milky Way. After Andromeda annexed the Milky Way, the solar system was completely wiped out and did not exist, and the vast space at that time was all Andromeda, not the Milky Way solar system, the earth has been completely destroyed, and human beings have been extinct. Therefore, I want to destroy Andromeda first and protect the Milky Way Solar System.

If the Andromeda Galaxy and the Milky Way begin to collide, humanity should go to other galaxies to protect itself.

1.If the Andromeda galaxy collides with the Milky Way, even if it is integrated, if its stellar object density is similar to that of the Milky Way, then it will only add a coin between the Sun and neighboring stars. Space is still very empty and doesn't look crowded.

The end result is that the two galaxies are integrated into a larger galaxy, which would take millions of years to become an elliptical galaxy. The massive uplift of 1 billion planets will replace the narrow Milky Way.

2.The Andromeda Galaxy is a spiral galaxy, about twice the size of our Milky Way, about 2.54 million light-years away, and currently, the Andromeda Galaxy is approaching our Milky Way at a speed of 500,000 kilometers per hour. If we calculate at this rate, in 3 billion years, a huge collision between the Milky Way and the Andromeda Galaxy will occur.

There are so many galaxies in the universe that are in constant motion, from Earth, some galaxies are far away from us, and some are close to us.

3.The collision of galaxies is more like a fusion. There are countless stars and celestial bodies in galaxies, there are countless thumbnails, but in fact, the distance between two stars and two stars is very far, ranging from billions of kilometers to decades or centuries.

After the collision of the Milky Way and the Andromeda Galaxy, although some celestial bodies will collide, the proportions will not be too large.

Hundreds of millions of years later, we can think of the collision between the Milky Way and the Andromeda galaxy as a science fiction movie. After all, at that time, human technology was more than enough to cope with these things happening. The Earth's environment must be protected.

Now human beings can only live on the earth and rely on the earth to develop their own technology. If the earth's environment is destroyed, it will also have a great impact on the technological development of human beings. So far, the Milky Way has been formed, and there have been galactic integration events in history.

The above is the answer to the question of how human beings should choose to protect themselves if the Andromeda Galaxy and the Milky Way start to collide.

I think that when the time comes, humanity can move to other planets or other galaxies, and use this way to seek self-preservation.

At that time, it was a question of whether human beings still existed, and if they had already entered a higher civilization, there was no need to worry.

Scientists have determined the motion of the Andromeda Galaxy relative to the Milky Way based on the observation data of the Hubble Telescope, and judged that the Andromeda Galaxy will collide with the Milky Way in 30 years, and if the Andromeda Galaxy and the Milky Way begin to collide, human beings will use scientific means to change the trajectory of the galaxy.

The solar disturbance system will disappear slowly, because there are many planets in the Milky Way and Andromeda Galaxy, and the collision of these planets is very scary, and the solar system may disappear in the collision.

The solar system will occur**, and many planets will be destroyed by the magnetic field and pressure of the universe.

I don't think this is possible, although we see that they are relatively close to the naked eye, and it is speculated that this situation may also occur, but the celestial bodies are all mutually restricted, and the masks affect each other, and the whole body is moved by themselves, and there is definitely no single base that will appear in this situation.

When two typhoons collide, what happens to the atoms that make up the water molecules?

First of all, the sun has entered the red giant period at that time, and the brightness and temperature of the sun will be much higher than now, and even if the earth has not been swallowed by the sun, it will become extremely unsuitable for survival.

Assuming that the above situation is not considered, we are still on Earth, what will happen if two galaxies collide?

If you look at it bigger, the universe is actually very empty.

It's like a football field with two colonies of about 20 ants each, each more than 10 meters apart, and they're moving closer to each other. So it is conceivable that even if these two groups of ants run together, the chance of individuals colliding with each other is very small.

So the fusion of the Milky Way and the Andromeda galaxy will rarely collide in substance, and then merge into a much larger galaxy.
