Study shows that center of the galaxy has thousands of black holes
A new study by American and Chilean scientists has revealed that the center of our galaxy is inhabited not only by a giant black hole, but by thousands of them. According to information published in the journal Nature, the central area of the Milky Way contains approximately 10, 000 black holes.
For decades, scientists believed that black holes "sank" in the center of the galaxy and accumulated there. But the scientists had no evidence that these exotic objects had gathered in the center of the Milky Way.
Looking for black holes
According to Columbia University astrophysicist Chuck Hailey, it is surprising that one can have such a large prediction of objects while finding no evidence of them.
Black holes are almost impossible to detect, but those that are accompanied by objects (such as a star in orbit) interact in a way that allows them to be identified by X-ray emissions.
The team then searched for signals in a region about 3 light years away from the massive black hole located in the center of the galaxy and found dozens of black holes connected with celestial objects.
Relevance of Discovery
Locating so many black holes in such a small region is quite significant, because so far scientists have found evidence of only about five dozen black holes across the galaxy - 100 light years across.
In addition, the center of our galaxy certainly has much more than the dozen black holes that have just been detected. The researchers used what is known about black holes to extrapolate what they saw to what they could not see. Their calculations show that there must be several hundred star-paired black holes in the galactic center, in addition to the 10, 000 isolated black holes.
Hailey believes that what they have discovered should help theorists make better predictions about how many cosmic shocks can occur and generate detectable gravitational waves. Scientists have only recently begun to notice these ripples in spacetime, which were predicted by Albert Einstein about a century ago.
