They will find a black hole that can rotate space

The international research group led by the ISRA and NASA has just found a bare hole in the binary system 4U 1630-47 that is spinning at almost the highest speed allowed by the theory of general proportionality from Einstein. In fact, its rotation is so fast that the object forces the surrounding space to rotate next to it.
According to researchers who used AstroSat and Chandra X-rays from NASA in NASA, whose work will soon be published in the Astrophysical Journal, investigate black holes with high rotation speeds. test the theories of our universe, including proportionality.
It all started in 2016, when AstroSat found a black hole in the binary system (two objects that circled each other) 4U 1630-47. From the very first moment, a series of violent outbreaks of X-rays triggered the attention of researchers. Shortly thereafter, the Chandra Observatory confirmed the results and it became clear that this black hole was not the same as the other.

X-ray emission from a black hole occurs when the surrounding substance (mainly gas and dust) precipitates and "eats" it. These emissions allowed scientists to realize that the black hole, the mass of which was ten times the sun, spun at its own breathtaking speed. The black hole rotation speed may vibrate between two values ​​between 0 and 1. And the 4U 1630-47 black hole rotation speed was 0.9, which is almost the same as the speed of light.
The fact that researchers left openly because Einstein's theory means that if a black hole is able to turn so quickly that it can make room next to it.
To date, twenty holes known in our galaxies, it is only possible to measure the four other rotation speeds. And the system 4U 1630-47 is undoubtedly the fastest of all. Scientists believe that if we know the black holes correctly, a combination of factors such as rotation speed, related matter, and high temperatures may be the key to understanding how galaxies are formed.

How do you know how fast they rotate?

Mass and speed are two main features that describe the black hole. But though dough can be
calculate easily, by severity, find out that turnover is much more complicated.
According to Mayukt Pahar's research, "rotation speed measurements are very difficult to perform and can only be performed using the very high-quality X-ray images of the binary star system, that the black hole absorbs the material for its companion."
If the calculations are correct, the black hole in the binary system 4U 1630-47 could be the key to find out how these extra items affect the state. And they reveal an unknown process that led to the formation of galaxies.
