Supervoid Eridani is the largest, coldest and coldest place in space that scientists still cannot explain.

Eridan's Void (Eridanus Supervoid) – it is the largest "hole" in outer space and was first discovered on August 24, 2007. And this great something is located near the constellation Eridanus.

According to the most conservative estimates, the width of this area is equal to 150 before 500 million light years, and a depth of up to 10 billion light years (according to calculations, the entire universe extends for 93.5 billion light years).

In addition, this area is colder than any other place in the universe, and most importantly – scientists still cannot explain how and when the Eridani Supervoid could appear. In this article I will tell you what I did manage to learn about Eridanus Supervoid, as well as what exotic theories are being built around it.

What is known about Eridani's super void

The first microwave radiation map of our Universe was first compiled back in 2004 by the WMAP satellite, and on this map scientists were able to see an incredibly "cold spot" This turned out to be immediately 70 microkelvin colder than the average temperature of the relic radiation (which is 2.7 Kelvin), and the average temperature difference is only 18 microkelvin.

This was a real challenge to modern theory. Indeed, according to generally accepted concepts, the space of the Universe is homogeneous, which means that microwave radiation should be approximately the same in all its parts.

But that's not the only oddity found in the spot. So such anomalies were recorded in it, which did not fit into the generally accepted theory: for example, signals from one side of the sky were strong weaker than on the other, and an area was also found where the temperature was 150 microkelvin lower, which, in principle, could not exist.

And yes, initially the scientists took the obtained data only for a malfunction of the equipment, but further research confirmed the reality of the object, and scientists began to speculate.

How scientists try to explain the emptiness of Eridani

Since the discovery of this great void, scientists have been constructing a variety of theories and guesses.

So in October 2007, two astrophysicists N. Turk (Cambridge) and M. Cruz (Cantabria) put forward their theory that the "cold spot" found in the constellation Eridanus is nothing other than the oldest flaw in the fabric of the Universe, which can be compared with a layer of ice, where bubbles have been preserved air.

According to this version, after only one billion years, the cooling matter in the Universe was unevenly distributed, and this is how voids arose - residual traces of the early Universe. True, the scientists themselves admitted that they could not prove their theory in any way.

But then it was more interesting. So in May 2008, another theory was put forward, in which the "cold spot" was recognized as a real object, but they refused to believe that there was a continuous void.

Indeed, according to the calculations, any void is too small to form such a spot. And then the theory arose that this cold spot – it is the gravitational influence of another universe.

This was stated by professor at the University of North Carolina L. Mersini-Houghton. So, according to her reasoning, standard cosmology is unable to explain in any way such a giant cold hole.

This means that it can be a "fingerprint" of another Universe. And the main reason for this is the presence of quantum communication. This notorious connection does not allow galaxies to form in this place. And in fact, emptiness – this is a passage to another Universe, from which our Universe separated from you in the first moments of the Big Bang.

Despite the seeming absurdity of this theory, some scientists believed in it and developed it before that if our Universe is just one of many, then it means that there should be such "spots-passages" several.

So after a careful study of the night sky, scientists discovered both the northern and southern cold spots.

In March 2009 in Australia, astronomers tracked almost 41% southern hemisphere sky, found order 500 such voids and once again confirmed the reality of the void of Eridan. But after analyzing 21% northern hemisphere did not confirm the existence of a parallel void.

But, despite all these works, the general assessment of L. Mersini-Houghton was given as too exotic (unreal).

At the beginning of 2010 in the magazine "The Journal of Cosmology"A version was expressed that the super-emptiness of Eridan – this is nothing more than an incredible black hole, and its mass is comparable to the mass of the rest of the Universe, and our Universe revolves around this great Nechta. And it was assumed that in the distant future, this black hole will swallow our universe.

Already in 2013, the Planck satellite performed a refinement of the microwave radiation map of the Universe, and the “cold spot” was confirmed and even turned out to be larger than previously thought.

Further research showed that the void is actually not absolutely empty, and it contains only less matter than in the rest of the Universe, only 20-30%. But why in one place the super-void and the cold region coincided, scientists still cannot understand.

To this day, scientists are struggling with the riddle of the super-void Eridanus, in which modern theories simply do not work. So, it is quite possible that this is really a "door" to another universe. But with existing technologies and knowledge, humanity will not learn anything.
