Cosmic Web The wall of a galaxy that stretches hundreds of millions of light years. The proposed idea is that galaxies are not randomly distributed. and may be an important part of the space map.
What is cosmic fiber?
cosmic fiber Or galaxy filament, from the study of physical cosmology, is the largest structure known to man and appears in the universe. The thread-like structure has a length of approximately 50 to 80 h-1 megaparsec, spanning a large portion of empty space in the universe. The cosmic web is made up of many galaxies that are drawn together by gravity. There are many galaxies that are close together called galaxy cluster
In 2006, scientists announced their discovery. Three cosmic filaments line up to form the largest structure ever known to mankind, called Lyman alpha blobs. And in 2019, scientists were able to image them. cosmic fiber For the first time, the characteristics of cosmic fibers They are strands of light, like a large network of galaxies that are pulled together by gravity. It’s like a connecting path of galaxies.
Origin of cosmic fibers It is believed to be something that is left over from The Big Bang is in the past and is what stores almost all of the gases of space. And it will supply that gas to create and nourish stars and galaxies like a blood vessel.
Astronomers have known for some time that Various galaxies The universe is not randomly distributed. But it spreads systematically into a structure similar to fibers. Astronomers can map this structure by studying the distribution of galaxies. Many nebulae also lie along this structure.
expansion of cosmic fiber
scientist Many people believe that the universe is expanding through cosmic filaments. It might be part of that process. which a team of astrophysicists from the University of Michigan in the United States Found some abnormalities indicating that The mechanics of the universe are not pushing for the expansion of space. Including driving the growth of cosmic fiber alone But there is also a mysterious energy holding back the process.
As Dr. Nguyen Nhat Minh, an astrophysicist at the University of Michigan, stated that The universe is made up of matter that forms galaxies and large-scale structures such as the cosmic filament. It is also full of empty space or space that is expanding more and more. until causing various galaxies Separated more and more from each other.
As for the mechanism of formation and aggregation of space objects that should have dispersed after the Big Bang, Made possible by gravity, from dark matter, in opposition to the ceaseless expansion of space. That is powered by a mysterious energy that scientists call dark energy.
Mammoth One Large Cosmic Filament
Mammoth One is a large structure of cosmic fibers. An international team of astronomers has announced the discovery of a giant hydrogen nebula located approximately 100 kilometers away. Ten billion light years away is called Mammoth One (MAMMOTH-).
The interesting thing about Mammoth One lies in the fact that There is no energy source in that area. But it is very bright. Scientists therefore speculate that Mammoth One may be one of the main structures of the cosmic web. This is because the density of newly formed galaxies is very high.
Incidentally, 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 fiber with the evolution of the universe
Many astronomers believe that cosmic fiber Affects the evolution of the universe After the discovery of Mammoth One in 2017, it was later discovered The largest cosmic filaments to date include: The Hercules–Corona Borealis Great Wall measures approximately ten billion light years in length.
The Hercules–Corona Borealis Great Wall is therefore the largest structure in the observable universe. Until it received the nickname galaxy wall The largest structure in the universe was the subject of the gamma ray observation. is a large group of galaxies that form a giant disc approximately 10 billion light-years long, 7.2 billion light-years wide and nearly 1 billion light-years thick. It is in the constellations Hercules and Corona Borealis or Northern Crown Star
Hence the names Hercules – Northern Crown or Hercules – Corona Borealis. The Great Wall refers to a vast collection of galaxies of all shapes and sizes. The most obvious benefit of the cosmic filament might be to make it possible to Map of the universe or map of space Easier to do
However, the matter of the cosmic fibers Scientists around the world still have a lot to study. Due to its high complexity Both forms of connection process of formation and creating an impact on the universe
