Nasa reveals a black hole that rotates the space around it

A team of researchers from Indian Space Research Organization (ISRO) and NASA has discovered a black hole that rotates virtually to the maximum speed that is possible according to the theory of relativity for Einstein. Its speed is such that it forces the surrounding space time to turn beside it.

The rotation speed of a black hole varies between 0 and 1 – light speed. According to the international team of researchers, this black hole has a rotation speed of 0.9, which is practically equal to the maximum possible speed. That speed is what causes it to disappear the time surrounding it, something that has surprised researchers.

The black hole has been located in the system 4U 1630-47 thanks to the Indian satellite AstroSat and to Chandra X-ray Observatory of NASA, according to the Hindustan Times. The research group, whose analysis will be published in The Astrophysical Journal, emphasizes that discovery is important as it tests relativity theory and generally the entire universe.

"Mass and rotational speed are the two characteristics that characterize black holes. The mass can be measured easier (…) But the calculations related to the rotational speed are very difficult to do. They can only be done using high quality x-rays of binary star systems where the hole absorbs the matter about the star as it accompanies, explains Mayukt Pahari, the head of the research chief.

The hole was located in 2016 and already scientists suspected that something strange was about it. They began to notice powerful outbursts of X-rays inside him, as a result of the matter striking inside him.

Researchers have added that if we continue to investigate the rotational speed of this and other fast black holes, its mass and matter and fast around it, we will solve one of the great mysteries of the universe: how galaxies breed.
