An international astronomical research team recently said that they have discovered many previously unknown "secret passages" in the cosmic galaxy close to us. These are invisible fibrous structures, mainly composed of "dark matter".
The new artificial intelligence algorithm developed by these astronomers can deeply analyze the data through autonomous learning, and then establish the dark matter distribution map of the adjacent universe.
In the past, people usually tended to study distant dark matter. In addition to the fact that gravity is relatively easy to detect on a large scale, the complexity of the large-scale structure of the universe will increase with time. The information from distant space is also very old, so the complexity of the cosmic structure reflected by these information is relatively low.
In order to understand the network structure of the modern universe, scientists usually simulate it in computers according to theoretical models. However, such a simulation requires a lot of calculation, and there is not enough detail to reflect the structure of the adjacent universe. Through machine learning, astronomers can predict where dark matter will appear relatively easily based on galaxy distribution and galaxy motion data.
An algorithm with autonomous learning ability can automatically supplement the deficiency of new data according to its "knowledge learned" from previous data. By this method, astronomers have recovered many important structures within the 200 million parsec (equivalent to 652 million light years) of the adjacent universe on the basis of more than 7000 galaxies/kloc-0. These structures include local galaxy clusters, Virgo galaxy clusters, celestial galaxy clusters and local cosmic cavities (space areas with relatively few galaxies).
Astronomers have also discovered many new structures that have never been seen before in the nearby universe. They found many tiny dark matter fibers between galaxies. These invisible fibers connect galaxies, like "secret channels" and "neural networks".
These dark matter fibers are of great significance in astronomical research. They keep in touch with ordinary matter through gravity. Studying these dark matter fibers can help us understand the dynamic characteristics of galaxies more deeply. For example, by studying the dark matter fibers between Andromeda and the Milky Way, we can know whether these two galaxies will collide in the future.
Dark matter has an important influence on the evolution of the universe. In fact, the structure of the modern universe is based on dark matter. These invisible mysterious substances dominate the fate of all entities in the universe and even human beings.
