Scientists have discovered a black hole is so large that growth theory contradicts these mysterious formations in the universe, reports Reuters.
According to estimates scholars, this black hole was formed about 900 million years after the Big Bang. But since measurements indicated that the black hole that has a mass of 12 billion times larger than the Sun, it contradicts the widely accepted hypothesis about the development and growth of these formations heavenly.
"Based on previous studies, it is the largest of all the black hole discovered that were formed at that time," he said Wednesday Fuyan Bian, a researcher at the Research School of Astronomy and Astrophysics at the University National Australia (ANU).
"The current theory has set a limit to how fast can a black hole grow, but it is too big to comply theory," he said.
The formation of super-massive black holes remains a hotly debated in the scientific community. However, many scientists thought a long time that the growth of black holes is limited.
Black holes grow, according to the theories advanced by researchers as the absorbing material. However, while the matter is absorbed, it will be heated and create radiation pressure, which will push away from its mass black hole.
"Basically, we have two forces which balance together and establish a limit for growth, and this is much less than we found," added Professor Bian.
The new black hole was discovered by an international team of researchers led by Professor Xue-Bing Wu from Beijing University in China in the Sloan Digital Sky Survey, a scientific project that collects data and images in 35% of the northern sky.
Australian National University is coordinating a similar project called SkyMapper, which investigates and monitors the southern hemisphere sky.
Researchers expect us to be identified black holes as both projects will advance their research.
