What is the emptiness of Boötes?
The Bötes void is the greatest emptiness in the famous universe. It is an area of 250 million light -years, located in the direction of the constellation Boötes, which contains only a few dozen galaxies crushed in the shape of a coarse tube. Boötes emptiness is so huge that its diameter is 2% of the diameter of the observable universe. They were discovered in 1981 by Robert Kirshner, Paul Schechter, Augustus Oemler JR and Stephen Shectman during a survey of galactic red strengthening, Boötes is one of the first large gratbed discovered and is therefore the most famous. Voides of this size are often referred to as superciodes.
Boötes emptiness is home to regions that probably have the lowest particle density throughout the observable universe. Although the average particle density in space is estimated to be one particle on cubic tracks, the central Boötes regions are likely to have particle density several times lower. It is not known what Quev gap exists antitia of dark matter, but would be particularly difficultIt is located due to lack of close galaxies whose gravitational behavior must be studied in order to derive its existence.
Boötes Void is so great that Greg Aldering, Astronome, currently with Lawrence Berkeley Laboratory, once noted: "If the Milky Way was in the middle of Boötes, we would not know that there were other galaxies in the 1960s." "If there are intelligent species on a few galaxies located near the center of emptiness, they would have quite a task that they seek to engage in an intergalactic colonization. It is assumed that these several galaxies exist in a gap as a species of" bubble wall ", resulting from the merger of two smaller cavities.
The magnitude of the Boötes emptiness is greater than the size predicted by our current understanding of the formation of the galaxy and the extensive structure of the vvesmir, creating a little secrets. It is assumed that the boötes void may haveLower "settings" from the moment of large bang, existing as a small place of reduced density in the "prehistoric atom" of the incredible matter that exploded to lead to our universe. Although the galaxy can be clearly seen in the direction of the sky, where the Boötes void is located, it has been found that all these galaxies are either relatively close to us or relatively distant, with a large gap in between.
