Astronomers estimate that there are at least 10,000 extraterrestrial civilizations in the Milky Way, some of which are much more technologically advanced than humans, and all of this will be due to the mysteries of the universe.
However, what is more interesting is the formation history of the Milky Way and the galactic core region, and there are many strange substances in the universe, such as black holes, whose birth provides researchers with a wealth of knowledge.
Not only that, but there are also some superstructures, such as the Laniakea Supercluster, how terrifying is Laniakea's Supercluster?
How did it come to be?
1. What is the Milky Way mainly made of?
According to astronomers' estimates, there are at least 100 billion stars in the Milky Way, but the exact data of the Milky Way is somewhat doubtful and can only be used as a reference.
In the 18th century B.C., Dimocritus proposed the idea of the "Rice Grain Nebula" by looking at the sky with his eyes, and then, in the second half of the 19th century, astronomers discovered a number of galaxies by looking at the sky with a telescope.
At the beginning of the 20th century, Hubble proposed the existence of "extraterrestrial civilizations" and estimated the number of extraterrestrial civilizations, such as galaxy groups, galaxy clusters and superclusters in the universe, forming the basic structure of the universe.
Among these structures are clusters of galaxies, clusters of galaxies, and superclusters of clusters.
In this group of galaxies, there are several galaxies, like the galactic core region of the continent, which is the early stage of the formation of the Milky Way, and the density and shape of the stars are related.
Among the nearest neighbor galaxies, the common spiral galaxy is the most dominant galaxy form, and the spiral galaxy may have absorbed gas and dust from other galaxies in the process of formation, so it is relatively flat in appearance and compact in arthropods.
The formation of galaxy clusters and superclusters still needs to be re-evaluated, and researchers used the Hubble Space Telescope to observe more than 50 supernova remnants in the universe and found that the evolution in the universe is less than expected, but the formation may be more violent than expected.
According to the data of the Milky Way, the Milky Way is expected to have 100 billion to 400 billion stars, which is equivalent to everyone in the Milky Way lighting up, but the space occupied is very small, which shows that the Milky Way is a very large galaxy.
In the Milky Way, there is a small angle, 2.5 degrees wide, through which astronomers can analyze the main galaxy composition of the galaxy.
In 1874, astronomers had limited information about the Milky Way, only spectral photographs of Shi Shen, the angles in the photos were too small, and the information in the photos was repeatedly linked, but the effect was not obvious.
It wasn't until 1917 that Hubble proposed the distance of the stars through his observations of the Wheat Lun Nebula, and there were 2 billion stars in the local galaxy group.
But the "Wheat Lun Nebula" is a very old star cluster, and it has evolved very slowly, and Hubble's conclusions may be different from those of other star clusters.
The distribution of the constant determines the distance of the "wheat lun nebula", so as to calculate the average distance of the star, and this study also makes a significant contribution to the estimation of the average distance of the silver system.
2. How did the Laniakea Supercluster form?
In the 1930s, Mason used a spectrometer to analyze 100 stars, analyzing galactic centers and extraterrestrial civilizations, until 1943, when Mason completed his research and analyzed the spectral lines of galactic cores.
It wasn't until 1953 that Becarr studied the data again, and the results showed that the spectral lines of the Milky Way were produced in the surrounding range of the Sun.
In 1997, Kagau Secla was selected as the three closest supergiant stars to the Milky Way in the supercluster, and he started the study of the supercluster again, and Sekra analyzed the spectral lines and found that the H-α spectral lines showed red movement, which indicates that the stars are in motion.
In 1997, his research showed that the average velocity of stars is 10 km, but in superclusters it reaches 20 km, and in the study of supernova remnants, through the observation of newly produced elements in supernova remnants, it was once again proved that galaxies are very fast, with a speed of 13 km, much faster than expected.
In 2004, Sekra analyzed the data again and found that the velocity of the silver series reached 700 kilometers, but in subsequent studies, there was uncertainty about this, so more experiments were needed in the study.
The Laniakea Supercluster is the largest basic structure in the universe that has been observed so far, and Laniakea was first discovered by the American astronomer and astronomer Harlan at Harvard University.
"Laniakea", which means "light from the burning of wood", is a dance made of feathers, which astronomers later called the Laniakea Supercluster, and also became the largest galaxy cluster in the universe, larger than the Milky Way, with a diameter of 520 million light-years and 100,000 galaxies.
The supercluster is composed of tens of thousands of galaxy clusters, which is a super-large structure of the modern universe, a super-large structure of the modern cosmic universe, with a long observation time, and its mass is about 10^16 solar mass, which is the Laniakea supercluster located in the constellation Scorpio.
According to the study of the Laniakea Supercluster, there are about 8,000 galaxies in the Laniakea Supercluster, 80-90% of which are elliptical galaxies.
According to astronomers' observations, the group of galaxies in the Laniakea Supercluster is 15 times that of the Milky Way, and its mass is 10^15 times that of the Milky Way.
At present, the observed Laniakea Supercluster is located in the constellation Scorpio, and the central region of the Laniakea Supercluster is also formed by the middle cluster of Laniakea Supercluster, and in the Laniakea Supercluster, there are other galaxy clusters.
3. The influence of the structure of the universe on the Milky Way.
To understand the formation of the Laniakea Supercluster, we first need to understand the Great Wall of the Universe and the formation of the Cosmic Void, which form the fibrous reticulum structure of the universe, and the distribution rules of the star camps in the universe follow the fibrous reticulated structure.
The fibrous reticular structure is consistent with the distribution of neurons in the human brain, and the distribution of neurons and galaxies is a fibrous reticular structure, which is the product of the same set of physical laws.
The arrangement of neurons and galaxies are consistent at the biological, physical and spatial levels, but there is a level of distinction between the fibrous reticulates of the universe, and the low-level galaxy groups and galaxy clusters are composed of a few hundred to hundreds of galaxies.
At the beginning of its evolution, it was relatively simple, but then it gradually merged with other groups of galaxies to form superclusters and superclusters, which are higher-level celestial systems.
The structure of the universe is gradually becoming more complex, which is the inevitable trend of the evolution of the universe, and the complexity of the universe is reflected not only in the matter of the universe, but also in the structural system of the universe, some of which are not much older than the Milky Way.
Between 5 million and 130 million years later, it has formed a rich celestial structure, such as a supercluster, which not only forms galaxy clusters, but also galaxies within galaxy clusters and stars within galaxies.
In the study of superclusters, there is not much communication between galaxy clusters and galaxy clusters, and galaxy clusters may throw stars directly into the galaxy cluster, thus forming galaxy clusters, and the exchange between galaxy clusters also takes a long time
If there is no interference from extraterrestrial civilizations, it will take a long time to form the observed structure, therefore, there may be a large number of extraterrestrial civilizations in the galaxy, and the space for exploration and communication of extraterrestrial civilizations is vast.
The Great Wall of the Universe is a very huge galaxy wall area, its length is about 500 million light years, its width is about 30 million light years, its mass is very large, 1 million times that of the Milky Way, a bit like the existence of the Earth's atmosphere, its structure is also fibrous network structure.
It is made up of hundreds of galaxies, and the Great Wall was discovered in 2013, it is a larger galaxy system than the Milky Way, and the density of stars in the Great Wall is extremely high, and sometimes there are black holes, and the material in the black hole will also evaporate.
The matter in the black hole will also eject new celestial structures, thus forming galaxy clusters, super-galaxy clusters, etc., thus forming a rich large celestial structure in the universe, while cosmic holes are composed of galaxy clusters, and the formation of voids may be affected by dark matter and dark energy, although dark matter and dark energy are hypothesized by scientists, but their impact on the universe is very large.
epilogue
Scientists continue to explore the mysteries behind the Laniakea Supercluster, but there are still many questions to be solved in the study of the Laniakea Supercluster, such as the formation of the Laniakea Supercluster.
The fibrous structure of the brain and galaxies is similar, which may reflect a universal law of physics that deserves more in-depth study.
