Scientists have discovered a huge invisible dark matter in galaxy clustersA July 2012 study found that the galaxy cluster Abel 222 Abel 223, two clusters of galaxies are connected through the dark matter filaments, as shown in Figure. The blue shadows and yellow outline shows the density of dark matter. The object in the sky about twice as large as the full moon. Recently, scientists have found a huge bunch of invisible dark matter in clusters of galaxies of the universe. These filaments formed two huge clusters of galaxies together 2.7 billion light-yearsAbel 222 Abel 223, between the bridges. The universe is considered to have been full of dark matter filaments, the mysterious substance which is a can not be directly observed, its presence is sensed only through its gravitational pull.-Before scientists in order to find the existence of dark matter filaments of various attempts, the theory predicts that clusters of galaxies formed in the intersection area of ​​the dark matter filaments. 98% of the substance of the whole universe is dark matter."This is the first time (dark matter filaments), through its gravitational focusing effect is conclusive detected, University of Munich, Germany, Observatory astronomers Jagger Dietrich, says," This is a remarkable finding, it confirmed by the standard theory of cosmic structure formation. It also confirmed previously thought impossible theory.Many astronomers believe that the need to wait until the telescope become more sophisticated to detect the presence of dark matter filaments, however, be inspired by Dietrich and colleagues never rare clusters of galaxies space geometry, detected the so-called weak gravitational focusing effect.According to Einstein's general theory of relativity, the huge celestial bodies will make the space-time is distorted around the side of it lead to any object through it, including light, along the curved path before the line. When the light from background objects, such as a galaxy, near a huge cluster of galaxies in the way to the Earth through the pictures will show the light was bent like because it is along the twisted path."The standard theory is that the filaments of the gravity-focusing effect is too weak so that current telescopes can not detect."Dietrich said, "When we found that the galaxy cluster system has such a special geometry, we realize that in fact still have a chance to detect this weak effect."Abel 222 Abel 223 in the sky background looks away from very close, in fact, very far away from the Earth observation field of vision between the two in fact. This means that the vast majority of binary systems group system quality is compressed into a small area in the sky, the light reaching the Earth from behind it issued are required to pass through the cluster of galaxies, which makes the weak gravitational focusing effect can be detected.Astronomers using data collected in observations by the Japanese Subaru telescope, Mauna Kea, Hawaii. These data are the observations of 2011, has been archiving has not been used. "Dietrich said," We then realized that these data can be adopted. "Although the gravitational focusing effect because it was too weak to be naked-eye observation to the research team by the light from more than 40,000 background galaxies statistical analysis to determine the objects are not observed between these two clusters of galaxies distorts time and space. This study is to establish a study in 2008, Dietrich, who found the heat in the filament region, suggesting that dark matter or existence. However, the study did not directly detected dark matter is any indication.Research scholars will continue to exist in other galaxy clusters near the search for dark matter filaments, has yet to find any clusters of galaxies can produce a strong gravitational focusing effect that can be directly observed from the Earth
