Scientists say that the collision between Milky Way and Andromeda has begun, why don’t we feel it?
For the past century, astronomers have been plagued by the contradictions of the universe. Even at the most basic level, the universe is in conflict with the contradiction between General Relativity and Quantum Mechanics . The universe should have slowed down, and the mysterious dark energy accelerated the expansion of the universe. Ten years ago, scientists discovered another contradiction, an accident that was about to happen.
initially was colliding head-on with its big neighbor Andromeda. It is predicted that the collision will occur in 4.5 billion years, but some scientists are concerned that the collision may have begun. This raises the question: Should galaxies be mutually exclusive? On the other hand, is this collision possible?
We know that although the universe is almost endless, it is still expanding, driving galaxies away from each other, and the inhabitants of a galaxy will not be able to find any adjacent galaxies in their sky, and they will face real loneliness, but humans may not face this loneliness, because scientists predict that Andromeda may hit the Milky Way, the black hole in the center of our Sagittarius A galaxy is similar to the Andromeda nucleus, an object not found in the P2 galaxy, which shows through blue shift that Andromeda and the Milky Way are at a speed of 110 kilometers per second, which is why so many scientists are afraid of Apophis flying by in 2029.
The distance between Andromeda and the Milky Way is 2.5 million light years, equivalent to 9.5 trillion kilometers, which means that the galaxy collapse will occur in 4.5 billion years, but the latest research in early 2022 shows that the merger of the two galaxies has begun because the region of the two is so large that we don’t feel anything. So the question is, will it have an impact on us and our planet?
The Great Andromeda Galaxy is a system of hundreds of billions of stars that orbit a central black hole on a dark moonless night. If you walk out of the busy light-polluted urban streets and head to a stargazing point in the forest, you will be able to see a blur of light that will become increasingly obvious in the sky over time. Unfortunately, in 4.5 billion years, as the sun gets bigger, our planet will lose all its moisture and become a hot gas pool.
According to the project to observe the deep space environment of Andromeda galaxies using the Hubble Space Telescope, the collision between galaxies is already underway, which is a huge impact, and will eventually form a huge galaxy, which will be twice the size of the previous one after it is formed. According to astronomers, the halo coverage area around the Milky Way is very large, but this halo may be very weak, and detecting its existence is almost impossible, especially in its thinnest place, and although we can't see it, it doesn't mean it is not there, just like the influence of the sun is far beyond Neptune .
Neptune is the furthest planet in our star system . The sun's magnetic field reaches the area called the Hell Circle through the Kuiper belt, and the galaxy halo extends further than people think, which is why these galaxies have begun to merge. It turns out that we underestimated Andromeda's size. However, in-depth observations of neighboring galaxies show that the extension of the Milky Way is far beyond our imagination, with a large number of meteors and cosmic dust bringing the Milky Way’s total diameter to about 200,000 light-years, meaning Andromeda is twice the size of our galaxy, but we haven’t even discovered the Andromeda’s surface, according to astronomers at the University of Notre Dame.
Their research on the upcoming galaxy shows that the distance between Andromeda halos is 2 million light years from the center is huge. The Milky Way has the atmosphere of the Milky Way, and this halo-like feature should also last at least one million light-years in each direction. If the size of these two galaxies is really that large, then their tips must be in contact. Galaxies mergers are violent, so if two galaxies do come into contact, it means that the most epic galaxy crossing in human history has begun.
Our galaxy is part of a galaxy cluster called local galaxy cluster . One day, this galaxy cluster , which consists of nearly 100 galaxies, may have all merged, and there is even evidence that this galaxy cluster itself may merge with the largest galaxy cluster, the Virgo galaxy cluster, the largest galaxy cluster, but even if the merger has begun, the two galaxy disks will still meet in 4.5 billion years, so we don’t have to panic that the sun becomes a red giant and consumes the earth. As the solar radiation reaching the earth increases, the brightness of the earth will greatly increase. The temperature on the surface of the earth will rise. The earth will soon experience the out-of-control greenhouse effect , and our earth will lose all moisture as it will evaporate, and the melted earth will appear like hell. By then, life on Earth will disappear, and sadly no one can witness this wonder.
As for the possibility of the sun colliding with another star, it is almost zero, but this does not mean that stars will not be affected by this huge event. Andromeda has about 1 trillion stars, while only 300 billion black holes in the Milky Way will merge with each other. Stars from two galaxies will be thrown into a new orbit around the center of the newly merged galaxy. The shock waves generated by the merger are likely to kick our star system out of the Milky Way together with the Sun and its planets, allowing it to survive independently. what you think?
