Determining whether a thing is big or small, we are guided mainly by comparing it with another thing. Everyone can determine for himself the largest object on earth. But any of the things you named will surely be smaller than other objects that can be found in the Universe. What are the biggest things in the universe?
Pleasant viewing and wonderful mood!
So let's go.
The largest asteroid
The most massive known this moment asteroid is Ceres. It weighs almost a third of the mass of the entire asteroid belt, and its diameter is about 950 km. Due to its impressive size, it was previously believed that Ceres is dwarf planet. Many astrobiologists believe that there could be an ocean beneath the asteroid's icy surface that could harbor life.
largest planet
The largest of the planets is located in the constellation Scorpio and is called WASP-17b (Jupiter on the left, WASP-17b on the right). It is located at a distance of about 1304 light years from us. Its diameter is 50% larger than that of Jupiter, but its mass is only 50% that of Jupiter. In addition to being the largest WASP-17b, it also has lowest density of the known planets: 13 times smaller than Jupiter and more than 6 times smaller than Saturn, which is the least dense in our solar system.
The biggest star
To date, the most a big star is UY Scutum in the constellation Scutum at a distance of about 9500 light-years from us. This is one of the brightest stars - it is 340 thousand times brighter than our Sun. Its diameter is 2.4 billion km, which is 1700 times larger than our sun, with a weight of only 30 times the mass of the sun. It is a pity that it is constantly losing mass, it is also called the fastest burning star. Perhaps that is why some scientists consider the largest star NML Cygnus, and others - VY Canis Major.
The biggest black hole
Black holes are not measured in kilometers, the key indicator is their mass. The most gigantic black hole is in the galaxy NGC 1277, which is not the largest. However, the hole in the galaxy NGC 1277 has 17 billion solar masses, which is 17% of the total mass of the galaxy. For comparison, the black hole in our Milky Way has a mass of 0.1% of the total mass of the galaxy.
largest galaxy
The mega-monster among the galaxies known in our time is IC1101. The distance to the Earth is about 1 billion light years. Its diameter is about 6 million light years and holds about 100 trillion. stars, for comparison, the diameter of the Milky Way is 100 thousand light years. Compared with milky way IC 1101 is over 50 times larger and 2000 times more massive.
The largest blob Lyman-alpha (Lyman-α blob - LAB)
Blobs (drops, clouds) Lyman-alpha are amorphous bodies resembling amoebas or jellyfish in shape, consisting of a huge concentration of hydrogen. These blots are the initial and very short stage of genesis new galaxy. The largest of them, LAB-1, is over 200 million light-years across and lies in the constellation of Aquarius.
In the photo on the left, LAB-1 is fixed by devices, on the right - an assumption of how it might look close.
largest void
Galaxies, as a rule, are located in clusters (clusters), which have a gravitational connection and expand along with space and time. What is in those places where there is no location of galaxies? Nothing! The area of the Universe in which there is only "nothing" is emptiness. The largest of them is the void of Bootes. It is located in close proximity to the constellation Bootes and has a diameter of about 250 million light years. The distance to the Earth is approximately 1 billion light years.
giant cluster
The largest supercluster of galaxies is the Shapley supercluster. Shapley is located in the constellation Centaurus and appears as a bright densification in the distribution of galaxies. This is the largest array of objects bound together by gravity. Its length is 650 million light years.
The largest group of quasars
The largest group of quasars (a quasar is a bright, energetic galaxy) is Huge-LQG, also called U1.27. This structure consists of 73 quasars and has a diameter of 4 billion light years. However, the Great GRB Wall, which has a diameter of 10 billion light years, also claims the championship - the number of quasars is unknown. The presence of such large groups of quasars in the Universe contradicts Einstein's Cosmological principle, so their research is doubly interesting for scientists.
Space Web
If astronomers argue about other objects in the Universe, then in this case, almost all of them are unanimous in their opinion that the largest object in the Universe is the Cosmic Web. Endless clusters of galaxies surrounded by black matter form "nodes" and with the help of gases - "threads", which outwardly very much resemble a three-dimensional web. Scientists believe that the cosmic web entangles the entire universe and connects all objects in space.

Looking at the night sky, you understand that you are just a grain of sand in the vast expanse of space.
But, many of us may also wonder: what is the most massive object known to date in the universe?
In a sense, the answer to this question depends on what we mean by the word "object". Astronomers observe structures such as the Great Wall of Hercules-Northern Corona, a colossal filament of gas, dust and dark matter containing billions of galaxies. Its length is about 10 billion light years, so this structure can be named after the largest object. But not everything is so simple. The classification of this cluster as a unique object is problematic due to the fact that it is difficult to determine exactly where it begins and where it ends.
In fact, in physics and astrophysics, “object” is well defined, said Scott Chapman, an astrophysicist at Dalhousie University in Halifax:
“It is something bound together by its own gravitational forces, for example, a planet, a star, or stars revolving around a common center of mass.
Using this definition it becomes a little easier to understand what is the most massive object in the universe. In addition, this definition can be applied to various objects depending on the scale under consideration.

But it's not even the largest planet in the solar system. Gas giants: Neptune, Uranus, Saturn and Jupiter are much larger. The mass of Jupiter, for example, is 1.9 octillion kilograms. Researchers have found thousands of planets orbiting other stars, including many that make our gas giants look small. Discovered in 2016, HR2562 b is the most massive exoplanet, about 30 times more massive than Jupiter. At this size, astronomers are not sure whether it should be considered a planet or classified as a dwarf star.
In this case, the stars can grow to enormous sizes. The most massive known star is R136a1, its mass is between 265 and 315 times the mass of our Sun (2 nonillion kilograms). Located 130,000 light-years from the Large Magellanic Cloud, our satellite galaxy, this star is so bright that the light it emits actually tears it apart. According to a 2010 study, the electromagnetic radiation emanating from a star is so powerful that it can carry away material from its surface, causing the star to lose about 16 Earth masses each year. Astronomers do not know exactly how such a star could form, and how long it will exist.

The next massive objects are galaxies. Diameter of our own galaxy Milky Way is about 100,000 light-years long, contains about 200 billion stars, with a total weight of about 1.7 trillion solar masses. However, the Milky Way cannot compete with the central galaxy of the Phoenix Cluster, located 2.2 million light years away and containing about 3 trillion stars. At the center of this galaxy is a supermassive black hole- the largest ever discovered - with an approximate mass of 20 billion suns. The Phoenix Cluster itself is a huge cluster of about 1000 galaxies with a total mass of about 2 quadrillion suns.
But even this cluster cannot compete with what is probably the most massive object ever discovered: the galactic protocluster known as SPT2349.
“We hit the jackpot by finding this structure,” said Chapman, leader of the team that discovered the new record holder. “More than 14 very massive individual galaxies located in space not much larger than our own Milky Way.”

This cluster began to form when the universe was less than 1.5 billion years old. The individual galaxies in this cluster will eventually coalesce into one giant galaxy, the most massive in the universe. And that's just the tip of the iceberg, Chapman said. Further observations showed that the overall structure contains about 50 satellite galaxies, which will be absorbed by the central galaxy in the future. The previous record holder, known as the El Gordo Cluster, has a mass of 3 quadrillion suns, but SPT2349 likely outweighs that by at least four to five times.
That such a huge object could have formed when the universe was only 1.4 billion years old surprised astronomers because computer model it was assumed that it would take much longer to form such large objects.
Given that humans have only explored a small portion of the sky, it is likely that even more massive objects could lurk far out in the universe.
The ancient pyramids, the tallest skyscraper in the world in Dubai, almost half a kilometer high, the grandiose Everest - just looking at these huge objects is breathtaking. And at the same time, compared to some objects in the universe, they are microscopic in size.
The largest asteroid
To date, the most big asteroid Ceres is considered in the universe: its mass is almost a third of the entire mass of the asteroid belt, and its diameter is over 1000 kilometers. The asteroid is so large that it is sometimes referred to as a "dwarf planet".
largest planet
In the photo: on the left - Jupiter, the largest planet in the solar system, on the right - TRES4
In the constellation Hercules is the planet TRES4, the size of which is 70% larger than the size of Jupiter, the most big planet in the solar system. But the mass of TRES4 is inferior to the mass of Jupiter. This is due to the fact that the planet is very close to the Sun and is formed by gases constantly heated by the Sun - as a result, in terms of density, this heavenly body resembles a kind of marshmallow.
The biggest star
In 2013, astronomers discovered KY Cygnus, the largest star in the universe to date; the radius of this red supergiant is 1650 times the radius of the Sun.
In terms of area, black holes are not that big. However, given their mass, these objects are the largest in the universe. And the largest black hole in space is a quasar, whose mass is 17 billion times (!) More than the mass of the Sun. This is a huge black hole at the very center of the galaxy NGC 1277, an object that is larger than the entire solar system - its mass is 14% of the total mass of the entire galaxy.
The so-called "super galaxies" are several galaxies merged together and located in galactic "clusters", clusters of galaxies. The largest of these "super galaxies" is IC1101, which is 60 times more galaxy where our solar system is located. The length of IC1101 is 6 million light years. By comparison, the Milky Way is only 100,000 light-years across.
The Shapley Supercluster is a collection of galaxies over 400 million light-years across. The Milky Way is about 4,000 times smaller than this super galaxy. The Shapley Supercluster is so much larger that the fastest spacecraft It would take the Earth trillions of years to cross it.
A huge group of quasars was discovered in January 2013 and today is considered the largest structure in the entire universe. Huge-LQG is a collection of 73 quasars so large that it would take over 4 billion years to traverse from one end to the other at the speed of light. The mass of this grandiose space object is approximately 3 million times the mass of the Milky Way. The Huge-LQG group of quasars is so grand that its existence disproves Einstein's basic cosmological principle. According to this cosmological position, the universe always looks the same, no matter where the observer is.
Not so long ago, astronomers managed to discover something absolutely amazing - a cosmic network formed by clusters of galaxies surrounded by dark matter, and resembling a giant three-dimensional spider web. How big is this interstellar network? If the Milky Way galaxy were an ordinary seed, then this cosmic network would be the size of a huge stadium.
Thanks to rapid development technologies, astronomers are making ever more interesting and incredible discoveries in the Universe. For example, the title of "the largest object in the universe" passes from one find to another almost every year. Some open objects are so huge that they baffle even the best scientists of our planet with their existence. Let's talk about the ten largest of them.
Relatively recently, scientists discovered the largest cold spot in the universe. It is located in the southern part of the constellation Eridanus. With its length of 1.8 billion light years, this spot has baffled scientists. They had no idea that objects of this size could exist.
Despite the presence of the word “void” in the title (from the English “void” means “emptiness”), the space here is not completely empty. This region of space contains about 30 percent fewer galaxy clusters than its surroundings. According to scientists, voids make up to 50 percent of the volume of the universe, and this percentage, in their opinion, will continue to grow due to super-strong gravity, which attracts all the matter around them.
superblob
In 2006, the title of the largest object in the universe was given to the discovered mysterious cosmic “bubble” (or blob, as scientists usually call them). True, he retained this title for a short time. This 200-million-light-year-long bubble is a gigantic collection of gas, dust, and galaxies. With some caveats, this object looks like a giant green jellyfish. The object was discovered by Japanese astronomers when they were studying one of the regions of space known for the presence of a huge volume of cosmic gas.
Each of the three "tentacles" of this bubble contains galaxies that are four times denser than usual in the universe. The clusters of galaxies and balls of gas inside this bubble are called the Lyman-Alpha bubbles. It is believed that these objects began to appear about 2 billion years after the Big Bang and are real relics. ancient universe. Scientists suggest that the bubble in question formed when massive stars that existed back in early times space, suddenly became supernovae and threw huge volumes of gas into space. The object is so massive that scientists believe that it is, by and large, one of the first cosmic objects to form in the universe. According to theories, over time, more and more new galaxies will form from the accumulated gas here.
Shapley Supercluster
For many years, scientists believe that our galaxy, at a speed of 2.2 million kilometers per hour, is attracted through the Universe somewhere in the direction of the constellation Centaurus. Astronomers suggest that the reason for this is the Great Attractor (Great Attractor), an object with such a force of gravity, which is already enough to attract entire galaxies to itself. True, scientists could not find out what kind of object it was for a long time. Presumably this object is located behind the so-called "zone of avoidance" (ZOA), an area in the sky, covered by the Milky Way galaxy.
However, over time, X-ray astronomy came to the rescue. Its development made it possible to look beyond the ZOA region and find out what exactly is the cause of such a strong gravitational attraction. True, what the scientists saw put them even more in a dead end. It turned out that beyond the ZOA region there is an ordinary cluster of galaxies. The size of this cluster did not correlate with the force exerted on our galaxy by gravitational attraction. But as soon as scientists decided to look deeper into space, they soon discovered that our galaxy is being pulled towards an even larger object. It turned out to be the Shapley Supercluster, the most massive supercluster of galaxies in the observable Universe.
The supercluster consists of over 8,000 galaxies. Its mass is about 10,000 more than the mass of the Milky Way.
Great Wall CfA2
Like most of the objects on this list, the Great Wall (also known as the CfA2 Great Wall) once also boasted the title of the largest known space object in the universe. It was discovered by American astrophysicist Margaret Joan Geller and John Peter Hunra while studying the redshift effect for the Harvard-Smithsonian Center for Astrophysics. According to scientists, it is 500 million light-years long, 300 million light-years wide, and 15 million light-years thick.
The exact dimensions of the Great Wall are still a mystery to scientists. It could be much larger than thought, spanning 750 million light-years. The problem in determining the exact dimensions lies in the location of this gigantic structure. As with the Shapley Supercluster, the Great Wall is partially covered by the "zone of avoidance".
In general, this “zone of avoidance” does not allow us to see about 20 percent of the observable (reachable for current telescopes) Universe. It lies inside the Milky Way and is dense clumps of gas and dust (as well as a high concentration of stars) that greatly distort observations. In order to look through the "zone of avoidance", astronomers have to use, for example, infrared telescopes, which can penetrate another 10 percent of the "zone of avoidance". Through which infrared waves cannot penetrate, radio waves, as well as near-infrared waves and X-rays, break through. Nevertheless, the actual inability to view such a large region of space somewhat upsets scientists. The "Zone of Avoidance" may contain information that can fill gaps in our knowledge of space.
Supercluster Laniakea
Galaxies are usually grouped together. These groups are called clusters. The regions of space where these clusters are more closely spaced are called superclusters. Previously, astronomers mapped these objects by determining their physical location in the universe, but recently a new way of mapping local space has been invented. This made it possible to shed light on information that was previously inaccessible.
The new principle of mapping the local space and the galaxies located in it is based not on the calculation of the location of objects, but on observations of the indicators of the gravitational influence exerted by objects. Thanks to the new method, the location of galaxies is determined and, on the basis of this, a map of the distribution of gravity in the Universe is compiled. Compared to the old ones, the new method is more advanced because it allows astronomers not only to mark new objects in the universe we see, but also to find new objects in places where it was not possible to look before.
The first results of the study of a local cluster of galaxies using a new method made it possible to detect a new supercluster. The importance of this study lies in the fact that it will allow us to better understand where our place in the universe is. Previously, the Milky Way was thought to be inside the Virgo Supercluster, but a new method of research shows that this region is only part of the even larger Laniakea Supercluster, one of the largest objects in the universe. It stretches for 520 million light years, and somewhere inside it we are.
Great Wall of Sloan
Sloan's Great Wall was first discovered in 2003 as part of the Sloan Digital Sky Survey, a scientific mapping of hundreds of millions of galaxies to identify the largest objects in the universe. The Great Wall of Sloan is a giant galactic filament made up of several superclusters. They, like the tentacles of a giant octopus, are distributed in all directions of the universe. At 1.4 billion light-years long, the "wall" was once thought to be the largest object in the universe.
The Great Wall of Sloan itself is not as well understood as the superclusters that lie within it. Some of these superclusters are interesting in their own right and deserve special mention. One, for example, has a core of galaxies that together look like giant tendrils from the side. Inside another supercluster, there is a high gravitational interaction between galaxies - many of them are now undergoing a period of merger.
The presence of the "wall" and any other larger objects creates new questions about the mysteries of the universe. Their existence goes against the cosmological principle, which theoretically limits how big objects in the universe can be. According to this principle, the laws of the universe do not allow the existence of objects larger than 1.2 billion light years. However, objects like the Great Wall of Sloan completely contradict this opinion.
Group of quasars Huge-LQG7
Quasars are high-energy astronomical objects located at the center of galaxies. It is believed that the center of quasars are supermassive black holes, which attract the surrounding matter. This results in a huge burst of radiation, the power of which is 1000 times greater than the energy generated by all the stars within the galaxy. Currently, the Huge-LQG group of quasars, consisting of 73 quasars scattered over 4 billion light-years, is in third place among the largest structural objects in the Universe. Scientists believe that such a massive group of quasars, as well as similar ones, are one of the reasons for the appearance of the largest structural ones in the Universe, such as, for example, the Great Wall of Sloan.
The Huge-LQG group of quasars was discovered after analyzing the same data that discovered the Great Wall of Sloan. Scientists determined its presence after mapping one of the regions of space using a special algorithm that measures the density of quasars in a certain area.
It should be noted that the very existence of Huge-LQG is still a matter of controversy. Some scientists believe that this region of space really represents a single group of quasars, while others believe that quasars within this region of space are located randomly and are not part of one group.
Giant gamma ring
Stretching for 5 billion light-years, the Giant galactic gamma-ray ring (Giant GRB Ring) is the second largest object in the universe. In addition to its incredible size, this object attracts attention due to its unusual shape. Astronomers studying bursts of gamma rays (huge bursts of energy that are formed as a result of the death of massive stars), found a series of nine bursts, the sources of which were at the same distance from the Earth. These bursts formed a ring in the sky, 70 times the diameter full moon. Considering that gamma-ray bursts themselves are quite a rare occurrence, the chance that they will form a similar shape in the sky is 1 in 20,000. This led scientists to assume that they are witnessing one of the largest structural objects in the universe.
By itself, "ring" is just a term to describe the visual representation of this phenomenon as seen from Earth. According to one of the assumptions, the giant gamma ring may be a projection of a certain sphere, around which all gamma radiation emissions occurred in a relatively short period of time, about 250 million years. True, here the question arises as to what kind of source could create such a sphere. One explanation is related to the assumption that galaxies can gather in groups around a huge concentration of dark matter. However, this is just a theory. Scientists still don't know how these structures form.
Great Wall of Hercules - North Corona
The largest structural object in the universe was also discovered by astronomers as part of their observation of gamma rays. This object, dubbed the Great Wall of Hercules - the Northern Corona, spans 10 billion light-years, making it twice the size of the Giant Galactic Gamma Ring. Since the brightest bursts of gamma rays produce more big stars, usually located in areas of space where there is more matter, astronomers each time metaphorically consider each such burst as a needle prick into something larger. When scientists discovered that there were too many gamma ray bursts in the region of space towards the constellations Hercules and the Northern Corona, they determined that there was an astronomical object here, most likely a dense concentration of galaxy clusters and other matter.
An interesting fact: the name "The Great Wall of Hercules - Northern Crown" was coined by a Filipino teenager who wrote it down on Wikipedia (anyone who does not know can edit this electronic encyclopedia). Shortly after the news that astronomers had discovered a huge structure in the cosmic sky, a corresponding article appeared on the pages of Wikipedia. Despite the fact that the invented name does not quite accurately describe this object (the wall covers several constellations at once, and not just two), the world Internet quickly got used to it. Perhaps this is the first time that Wikipedia has given a name to a discovered and interesting scientific point vision of the object.
Since the very existence of this “wall” also contradicts the cosmological principle, scientists have to reconsider some of their theories about how the universe actually formed.
space web
Scientists believe that the expansion of the universe is not random. There are theories according to which all the galaxies of space are organized into one structure of incredible size, reminiscent of filamentous connections that unite dense regions. These filaments are scattered between less dense voids. Scientists call this structure the Cosmic Web.
According to scientists, the web formed at a very early stage in the history of the universe. At first, the formation of the web was unstable and heterogeneous, which subsequently helped the formation of everything that is now in the Universe. It is believed that the "threads" of this web played a big role in the evolution of the universe - they accelerated it. It is noted that the galaxies that are inside these filaments have a significantly higher rate of star formation. In addition, these threads are a kind of bridge for gravitational interaction between galaxies. Once formed within these filaments, galaxies travel to galaxy clusters where they eventually die.
Only recently have scientists begun to understand what this Cosmic Web really is. Studying one of the distant quasars, the researchers noted that their radiation affects one of the threads of the Cosmic Web. The light of the quasar went straight to one of the filaments, which heated up the gases in it and made them glow. Based on these observations, scientists were able to imagine the distribution of threads between other galaxies, thereby compiling a picture of the "skeleton of the cosmos."
Thanks to the constant development of technology, astronomers are finding more and more diverse objects in the universe. Rank" largest object in the Universe" moves from one structure to another almost every year. Here are examples of the largest objects that have been discovered so far.
1. Supervoid
In 2004, astronomers discovered the largest void (the so-called void) in known universe. It is located at a distance of 3 billion light years from Earth in the southern part of the constellation Eridani. Despite the name "void", the 1.8 billion light-year void is not actually a completely empty region in space. Its difference from other parts of the Universe lies in the fact that the density of matter in it is 30 percent less (in other words, in the void less stars and accumulations).
Also, the Eridani Supervoid is notable for the fact that in this region of the Universe the temperature of microwave radiation is 70 microkelvins less than in the surrounding space (where it is approximately 2.7 kelvins).
2. Space blob
In 2006, a team of astronomers from the University of Toulouse found a mysterious green blob in space that became the largest structure in the universe at the time. This blob, dubbed the "Lyman-Alpha Blob", is a gigantic mass of gas, dust and galaxies that has "spread out" 200 million light-years across (that's 7 times the size of our galaxy, the Milky Way). Its light takes 11.5 billion years to reach Earth. Given that the age of the universe is most often estimated at 13.7 billion years, the giant green blob is considered one of the most ancient structures in the universe.
3. Shapley supercluster
Scientists have long known that our galaxy is moving towards the constellation Centaurus at a speed of 2.2 million kilometers per hour, but the reason for the movement remained a mystery. About 30 years ago, a theory appeared that the Milky Way attracts the "Great Attractor" - an object whose gravity is strong enough to attract our galaxy at a great distance. As a result, it was discovered that our Milky Way and the entire Local Group of galaxies are attracted to the so-called Shapley Supercluster, consisting of more than 8,000 galaxies with a total mass of 10,000 times the Milky Way.
4. Great Wall CfA2
Like many of the structures on this list, the Great Wall of CfA2 was recognized as the largest known object in the universe when discovered. The object is about 200 million light-years from Earth, and its approximate dimensions are 500 million light-years long, 300 million wide and 15 million light-years thick. It is impossible to determine the exact dimensions, since clouds of dust and gas from the Milky Way block part of the Great Wall from us.
5. Laniakea
Galaxies are usually grouped into clusters. Those regions where clusters are more densely packed and connected to each other by gravitational forces are called superclusters. The Milky Way, along with the Local Group of galaxies, was once thought to be part of the 110 million light-year Virgo supercluster, but new research has shown that our region is just an arm of a much larger supercluster called Laniakea, which spans 520 million light-years. years.
6. The Great Wall of Sloan
The Great Wall of Sloan was first discovered in 2003. A giant group of galaxies spanning 1.4 billion light-years held the title of the largest structure in the universe until 2013. It is located approximately 1.2 billion light-years from Earth.
7. Huge-LQG
Quasars are the nuclei of active galaxies, in the center of which (as modern scientists assume) there is a supermassive black hole, which throws out part of the captured matter in the form of a bright jet of matter, which leads to super-powerful radiation. Currently, the third largest structure in the Universe is Huge-LQG - a cluster of 73 quasars (and, accordingly, galaxies), 8.73 billion light-years away from Earth. Huge-LQG measures 4 billion light years.
8. Giant ring of gamma-ray bursts
Hungarian astronomers have discovered at a distance of 7 billion light years from Earth one of the largest structures in the universe - a giant ring formed by flashes of gamma rays. Gamma-ray bursts are the brightest objects in the universe, releasing as much energy in just a few seconds as the Sun releases in 10 billion years. The diameter of the discovered ring is 5 billion light years.
9. Great Wall Hercules - North Crown
At present, the largest structure in the universe is a superstructure of galaxies called the "Great Wall of Hercules-Northern Corona". Its dimensions are 10 billion, or 10 percent of the diameter of the observable universe. The structure was discovered thanks to observations of bursts of gamma rays in the region of the constellations Hercules and the Northern Corona, in a region 10 billion light years away from Earth.
10. Cosmic web
Scientists believe that the distribution of matter in the universe is not random. It has been suggested that galaxies are organized into a huge universal structure in the form of filamentous filaments or clusters of "barriers" between huge voids. Geometrically, the structure of the universe most closely resembles a bubbly mass or honeycomb. Inside the honeycombs, which are approximately 100 million light years across, there are practically no stars or any matter. Such a structure was called the "Space Web".
It may seem incredible, but space discoveries directly affect everyday life of people. Confirmation of this.
