The question “how many stars are there in the universe” is not easy to answer because of the lack of accurate information, yet there are no lack of estimates. To the question Â how many black holes there are in the universe Â Â some Italian researchers have found an answer: always an estimate, but more precise than the previous ones.
The research published in The Astrophysical Journal by a group of researchers from the Institute of Triestino SISSA (International Higher School of Advanced Studies) has seen the use of a computational approach for which in the list of black holes in the
In doing so, they calculated the birth rate of star mass black holes between five and 160 times the mass of the Sun during the lifetime of the Universe, suggesting finally the existence of about 40,000,000,000,000,000,000 black holes, or
The research will be the basis for investigating the rate of growth of black holes, their mass and distribution, as explained by Lumen Boco. Mr Alex Sicilia said that this work was particularly innovative precisely because of the approach adopted, which made the study one of the first, and one of the most robust, calculations ab initio of the mass function of the black hole.
If you want to stay stunned, here’s a picture of a myriad of supermassive black holes.
