The discovery of the largest structure in the universe, which is 10 billion light-years, changed the perception of scientists

There are many celestial bodies in the universe. From our point of view, the earth is a huge planet, with a diameter of 12,756 kilometers and a circumference of 40,000 kilometers. We drove at high speeds, and it was not more than a thousand kilometers a day. However, Jupiter’s volume is 1000 times the size of the Earth, and the Sun is 1.3 million times the size of the Earth. There are hundreds of billions of stars like the Sun in the Milky Way. The diameter of the Milky Way is known to be 160,000 light years, but in the observable universe, it is similar to a galaxy like the Milky Way. But there are trillions of them.

However, galaxies like the Milky Way are not cosmic The main body, at present, the”large-scale filamentous structure” composed of galaxies is the basic vein that constitutes the universe. For example, if the human body is a universe, these filamentous structures are like blood vessels or nerve veins in the human body, and galaxies Roughly equivalent to individual cells.

Recently, European media called the astronomer Daniel Pomaré of the University of Saclay in Paris German and others discovered a new giant cosmic structure in the Antarctic sky-“Antarctic giant wall (or”Antarctic wall”)”, which is at least 1.4 billion light years in length, and is famous for the cosmic giant structure”Sloan” The Great Wall (the large-scale cosmic structure is often named after the’Great Wall’) is similar. This huge cosmic structure contains many galaxies and even galaxy clusters, and it is also the largest material enrichment area known in the universe.

The largest known”large-scale filamentous structure” is”Wu仙-North Coronation” The Great Wall, which is a giant structure with a length of more than 10 billion light years, located in the direction of Wuxian-North Coronation , The closest place to us is about 9.6 billion light years, the farthest place is about 10.5 billion light years, traversing more than 10 billion light years of space, more than 1/10 of the universe diameter (93 billion light years), in 2013, Astronomers discovered it when looking for gamma ray bursts.

Because its furthest place is about 10.5 billion light from the sun The year, indicating that it was born about 3.2 billion years before the birth of the universe, astronomers believe that this giant structure challenges the existing theory of cosmology formation and inflation because it is irregular and uneven, which is not consistent with the universe. The gravitational and mass-energy characteristics of macroscopic celestial bodies exceed the scale allowed by astronomers’ cosmic formation and inflation models. Therefore, astronomers do not yet know the reason for the formation and existence of this giant structure. The original theory and model of the formation and inflation of the universe need to be partially modified.
