Cosmic Fibers The network that connects galaxies – National Geographic Thailand

The cosmic web is a galactic wall extending hundreds of millions of light-years. The proposed idea is that galaxies are not randomly distributed. It may be an important part of the space map.

What is cosmic fiber?

Cosmic fiber Galactic filaments, from the study of physical cosmology, are the largest structures known to man that appear in the universe. The thread-like structure is approximately 50 to 80 h-1 megaparsec long, covering a large portion of the universe's empty space. The cosmic web consists of many galaxies held together by gravity. There are many galaxies close together called a galaxy cluster

In 2006, scientists announced their discovery. Three cosmic strings line up to form the largest structure ever known to humanity, called alpha Lyman blobs, and in 2019, scientists were able to photograph them. Cosmic fibers for the first time Characteristics of cosmic fibers They are filaments of light, like a large network of galaxies pulled together by gravity. It's like a path connected to galaxies.

The origin of the cosmic fiber is believed to be something left over from the Big Bang that occurred in the past and is what stores almost all of the gases of space. This gas will provide the formation and nourishment of stars and galaxies, such as blood vessels.

Astronomers have known for some time that different galaxies The universe is not randomly distributed. But it spreads systematically in a fiber-like structure. Astronomers can map this structure by studying the distribution of galaxies. Many nebulae are also located along this structure.

Expanding cosmic fiber

Scientist Many people believe that the universe is expanding through cosmic threads. It may be part of that process. Conducted by a team of astrophysicists from the University of Michigan in the United States, they found some distortions indicating that the mechanisms of the universe do not push towards the expansion of space. Including driving the growth of a single cosmic fiber but there is also a mysterious energy hindering this process.

As stated by Dr. Nguyen Nhat Minh, an astrophysicist at the University of Michigan, the universe consists of matter that forms galaxies and large-scale structures such as cosmic threads. It is also full of empty space or space that is expanding more and more. Even causing different galaxies to become more and more separated from each other.

As for the mechanism of formation and assembly of space objects that should have been dispersed after the Big Bang, it became possible thanks to gravity, from dark matter, in the face of the continuous expansion of space. It derives its energy from a mysterious energy that scientists call dark energy.

Mammoths are great cosmic threads

Mammoth One is a large cosmic fiber structure. An international team of astronomers announced the discovery of a giant hydrogen nebula located about 100 kilometers away. One mammoth is called (MAMMOTH-) ten billion light-years away.

The interesting thing about Mammoth One lies in the fact that there is no power source in that area. But it's very bright. Therefore, scientists expect that the mammoth may be one of the main structures of the cosmic web. This is because the density of newly formed galaxies is very high.

By the way, the discovery of Mammoth One was previously published in the journal The Astrophysical Journal is a good confirmation that there are many undiscovered large objects in the Universe.

Cosmic fibers as the universe evolves

Many astronomers believe that cosmic fibers influence the evolution of the universe and after the discovery of Mammoth One in 2017, it was later discovered that the largest cosmic filaments to date include: The Great Wall of Hercules-Corona Borealis is about ten billion light-years long.

Thus the Great Wall of Hercules-Corona Borealis is the largest observable structure in the universe. Even earning the title the Galactic Wall, it was the largest structure in the universe that was the subject of gamma-ray observation. It is a large group of galaxies that form a giant disk about 10 billion light-years long, 7.2 billion light-years wide, and approximately one billion light-years thick. It is found in the constellation Hercules and Corona Borealis, or the northern crown star.

Hence the names Hercules – Northern Crown or Hercules – Corona Borealis. The Great Wall refers to a wide range of galaxies of all shapes and sizes. Perhaps the most obvious benefit of cosmic threads is making it possible to map the universe or map space easier to do

However, the issue of cosmic fibers still has much to study for scientists around the world. Due to their high complexity both forms of communication are the process of shaping and creating an impact on the universe
