What is the extensive structure of the universe?

On the highest observable stages, corresponding to billions of light -years, a cell appearance has a cellular appearance, which consists of massive "walls" and the fibers of the galaxies separated by huge cavities, the largest of which (Eridanus emptiness) is a billion of light years. Although the observable universe as a whole seems to be about 14.7 billion light years wide, it is an illusion, because a large part of light in space lasted a billion years to reach us. The actual average of the observable space is 92-94 billion light -years. This phenomenon is sometimes referred to as the "end of the size". Since the real universe can be many times greater than the observable universe, the concept of a particular structure can only be applicable to the smallest standards.

The largest known structure in Cosmos is Sloan Great Wall, discovered in 2003, which has a length of 1.37 billion light years and is about 1 billion light years. Because the galaxy in the large wall of Sloan is not actually bound,Like our own local group, it is not a technically structure, but it is usually said anyway. Before the discovery of the Sloan Big Wall was simply named the "large wall" the largest known structure, about 500 million light years long and 200 million wide, with a width of only 15 million light -years.

Our galaxy is built into a much larger structure called the virgin SuperCluster, composed of about 100 galactic groups, with an average of 200 million light years. The Virgin SuperCluster as a whole is attracted to gravitational anomaly in the neighboring Superkluster Hydra-Centaurus known as a great attractor. The largest attractor is the largest known concentration of the matter of the universe, equal to about 10,000 typical galaxies. Attempts to study it are more closely covered with a galactic Disc of Milky Way.
