Centaurus may have hit the galaxy, and scientists have found evidence that it was terrible 4.2 billion years ago

The collision between the planets can be said to be very serious. If you are not careful, it will cause life turmoil. Take the asteroid 65 million years ago. It was because of the impact on the earth, which caused a The large-scale life extinction crisis.

What are the consequences of galaxy collision?

To this day, the memory of this impact is still left on Earth, in the Yucatan Peninsulaspan>, there is also a crater with a diameter of 10 kilometers, and through simulation experiments, we also found out how powerful the asteroid impact generated. If human beings are facing that crisis, maybe we It’s hard to escape.

So, what happens if galaxies collide? Let’s say that collision between planets is the end of life, and collision of galaxies may be the beginning of life. Of course, the consequences of collisions between galaxies are first of all destruction, but after the destruction of the planet, it is likely to cause a”star-making movement” and then rebirth.

The stars in the Milky Way may be due to a collision

This star-making movement may allow this impacted galaxy to re-breed a new planet, and, with the combination of foreign bodies, perhaps, the resources of the newly emerging planet are even more Abundance, the possibility of life can be higher. According to a report in Science and Technology Daily in June, the Milky Way Galaxy may have encountered a galaxy collision between 6.2 billion and 4.2 billion years ago. Among them, it may be because of this collision that stars such as the solar system were born.

At present, this statement is just the result of speculation by scientists through the Gaia space probe, but if you want to examine whether the solar system was born by a collision, you need more in-depth evidence. Can also prove.

At present, the Gaia Space Telescope Research Group stated that they will provide new evidence again between 2020 and 2021, and they may be able to solve this mystery by then. So, what is this galaxy that once struck the Milky Way? Currently, scientists are targeting the Milky Way galaxy, the largest globular galaxy in the local galaxy group, the Centauri dwarf galaxy.

What happened to the Milky Way in this collision?

This galaxy surrounds the Milky Way and is regarded as the satellite galaxy of the Milky Way, but from previous records, Centauri several times the dwarf galaxy wanted to pass through the Milky Way, and the results from the current observations also indicate that Centauri Dwarf galaxies are being absorbed by the Milky Way.

If this dwarf galaxy actually collided with the Milky Way, then it could just explain why the Milky Way is not the same as other galaxies. According to the data observed by astronomers, the edge of the Milky Way has the image A”warped structure” that lifts up like a skirt.

Through research, it is found that this warped structure is not composed of dark matter and other factors. From the speed of operation, it is more like the result of a”galaxy collision”. Therefore, Some scientists speculate that perhaps after that collision, warped structures appeared on the edge of the Milky Way.

Summary:

Some researchers have said that in the next 3-40 billion years, the Milky Way and the local galaxy group The largest galaxy, the fairy galaxy, collided. But in fact, a long time ago, the Milky Way may have encountered a collision, and after this collision, the Milky Way appeared more stars and other celestial bodies, but at the same time, the body of the Milky Way also appeared out of shape.

Regarding this conclusion, the Gaia space probe will give more detailed details in 2021 or 2022. At that time, let us see if this statement is correct. .
