ISRO, NASA just spotted a black hole spinning so fast that it could be making space itself rotate
AstroSatand NASA’s Chandra X-Ray Observatoryhave confirmed the discovery of a black holespinning close to the maximum possible speed.
- A black hole spinning that fast can make
spaceitself rotate according to Einstein’s theory of relativity.
- This black hole is only one of five to have an accurately measured high spin rate.
- Researchers hypothesise that this could be the key to understanding how galaxies are formed.
In 2016, India's first dedicated astronomy satellite, the AstroSat, spotted a black hole in the binary star system called 4U 1630-47, which is bursting out X-rays that astronomers found unusual.
Those X-rays were caused by gas and dust falling into the black hole, which is about 10 times the mass of the sun, and they revealed to researchers that the object is spinning very, very rapidly.
In fact, according to NASA this particular black hole is spinning very close to the limit set by Albert
Currently, scientists only have two ways of measuring
Einstein's theory further implies that if a black hole spinning that fast, then it is capable of making space itself rotate.
In fact, if the conditions around black holes are hypothesised to be correct, then the high spin rate coupled with the gaseous elements entering the black hole and high temperatures, could be the key to understanding how galaxies are formed.
Including the black hole discovered by the AstroSat, there are only five black holes have accurately measured high spin rates. Even if you're not taking spin rates into account, this black hole of one of only 20 others that have been spotted in the Milky Way Galaxy.

The study was conducted by researchers from multiple institutions led by the Tata Institute of Fundamental Research (TIFR) and has been accepted for publication in The Astrophysical Journal.
