Cosmic inflation (which is thought to have started a fraction of a second after the Big Bang) was the period during which a mass of hot particles spread through the darkness unbelievably fast, possibly because of repulsive gravity, until they cooled down and formed an vast cloud of neutral hydrogen gas 400,000 years later.
Astronomers on Wednesday declared the black hole, residing at the centre of a highly bright celestial object named a quasar, is located about 13.1 billion light-years away from Earth. Scientists have now found a super-sized black hole.
"Gathering all this mass in under 690 million years is an enormous challenge for theories of supermassive black hole growth", said co-author Eduardo Bañados, from the Carnegie Institution for Science. Reionization allowed photons to shoot through infinite space and light up the universe. When we were looking at further distances, we were also looking for the history because of the time it takes for light to move across the universe.
"It was the universe's last major transition and one of the current frontiers of astrophysics", Bañados said. When gravity caused matter to coalesce into stars and galaxies, they spewed enough energy to excited the neutral hydrogen into losing an electron-ionizing. According to experts, in connection with the displacement of the black hole sees to be what it was more 13 billion years ago.

The discovery of a massive black hole so early on may provide key clues on conditions that abounded when the Universe was young.
"The new quasar is itself one of the first galaxies, and yet it already harbors a behemoth black hole as massive as others in the present-day universe", co-author Xiaohui Fan of the University of Arizona's Steward Observatory said in a statement.
"This finding shows that a process obviously existed in the early Universe to make this monster", Dr Bañados explained.
The team used two Magellan telescope instruments to observe the supermassive black hole: FIRE, which made the discovery, and Fourstar, which was used for additional images.Читайте также: Investec warns of fallout from Steinhoff crisis
"Withseveral next-generation, even-more-sensitive facilities currentlybeing built, we can expect many exciting discoveries in the very earlyuniverse in the coming years", Stern said.
The was published in the British journal Nature.
The object was examined using ground-based telescopes in Chile and Hawaii and NASA's orbiting Wide-field Infrared Survey Explorer. The observations give us a riveting peek back in time.

It is surrounded by neutral hydrogen, indicating that it is from the period called the epoch of reionization, when the universe's first light sources turned on.При любом использовании материалов сайта и дочерних проектов, гиперссылка на обязательна.
