The supermassive black hole Sagittarius A*, which is located at the center of the Milky Way, spins at the maximum speed that the laws of physics allow it to have. This conclusion was reached by a team of scientists who analyzed its image using artificial intelligence.
Black hole Sagittarius A*
A group of European astronomers has concluded that the supermassive black hole Sagittarius A* rotates at a speed that is close to the maximum speed allowed by the laws of physics. The researchers came to this conclusion after analyzing its images using artificial intelligence.
In general, images of Sagittarius A* were obtained several years ago using the Event Horizon virtual telescope.They have become a sensation despite the fact that they show only the accretion disk around the monster, where little can be distinguished.
Nevertheless, scientists decided to use artificial intelligence to figure out what was going on there based on the data on which this image was built. AI has created millions of simulations of a black hole, and scientists were able to understand what was going on there based on their statistical analysis.
Maximum speed
The rotation speed of a supermassive black hole can be anything from practically zero to a certain maximum value determined by the laws of physics. Regarding Sagittarius A*, scientists for some time thought that it practically didn’t rotate, but later its rotation rate was recognized as quite significant.
A new study has confirmed the findings that the rotation rate of Sagittarius A* is close to its maximum. Moreover, one of its poles is almost turned towards the solar system and we can see the glow of hot electrons near it. But the magnetic fields in the vicinity of this object behave quite differently from what scientists expected.
The scientists also subjected images of another black hole to AI analysis. It is located in the galaxy M87 and is also found to be spinning quite fast, although slower than Sagittarius A*.
