A gigantic black hole from the early days of the universe and astronomers are puzzled about it. Well the gravity monster is so huge that it According to prevailing theories really should never have been created. Astronomers have discovered a monstrous black hole with the mass of twelve billion suns in the early universe. The mass monster sits in the heart of an active galaxy, so the light shines like 420 trillion suns. This so-called quasar shines across almost the entire visible universe to us, such as the international team led by Xue-Bing Wu of the University of Beijing in the British journal “Nature” reported. The quasar SDSS J0100 with the catalog number + 2802 is 12.8 billion light-years away according to the measurements of researchers from the Earth, its light was thus 12.8 billion years to help us move. This provided researchers a window into the distant past of the cosmos: As the light from the quasar took his journey to us, the universe was only 900 million years old was. Around this time, ended the so-called Dark Ages of the Universe with the flare-up of the first stars. It is unclear how could arise as a massive black hole from the Big Bang to this cosmic dawn in the comparatively short time. “To form a black hole so big so fast, is difficult to interpret with the current theories,” said co-author Fuyan Bian from the Australian National University. “The black hole at the center of this quasar has won a huge mass in a short time.” It is therefore the most massive and brightest known object of this cosmic age. Black holes grow by incorporative surrounding matter. This matter forms giant whirlpool, called accretion disks, and glow brightly, before she falls into the black hole. The strong radiation of matter falling down presses against the following matter and resists this. The appetite of the black hole is thus a natural limit. The newly discovered black hole must have eaten almost matter since the Big Bang in the maximum possible speed to achieve the observed mass. This is surprising, because the astronomers assume that the radiation pressure accretion after 10 to 100 million years first usually brings to a halt, as the not involved in the study, researchers Bram Venemans from Heidelberg Max Planck Institute for Astronomy in an accompanying commentary in “Nature” explained. The researchers hope to learn with the further investigation of the unusual object more about the conditions in the early universe. In addition, you can use its chemical composition of the intergalactic gas explore across time and space. Because the light from the quasar this gas on the long road to Earth has screened at different times and in different places, while collected his characteristic fingerprints.

Otkrivena gigantska crna rupa Znanstvenici su otkrili crnu rupu koja ima 12 milijardi puta veću masu od Sunca i koja je nastala 900 milijuna godina poslije Velikog praska Supermasivna crna rupa nevjerojatno velike mase, 12 milijardi puta veće od mase našeg Sunca koju su znanstvenici nedavno otkrili ima još jednu zagonetku - vrijeme nastanka. Naime, procijenjeno je da je nastala samo 900 milijuna godina nakon Velikog praska. Golema crna rupa udaljena je 12,8 milijardi svjetlosnih godina od Zemlje. Astronomi nisu u stanju objasniti kako je toliko velika crna rupa mogla nastati tako rano u povijesti svemira, odmah nakon što su nastale prve zvijezde i galaksije.
