Scientists find the strongest black hole, Friday, 4 September 2020 03:29 am
According to Sputnik, a package of unusual gravitational waves was recorded on May 21, 2019 and named as GW1905. The signal lasted only 0.1 seconds, but it caught the attention of scientists.
Studies have shown that the source of the signal was a supermassive binary system: two black holes of mass 66 suns and 85 suns as a result of merging formed a black hole of mass 142 suns.
The statement says: “The main aspect that attracted the attention of astrophysicists is that the fusion remnants belong to the category of so-called medium-mass black holes … They lie in the mass range (from 100 to 1000 solar masses), where a black hole has never been observed before.” .
It is also observed that the most massive component of the binary system lies in a mass band that conflicts with stellar evolution theory and thus challenges our understanding of the final stages of the life of massive stars.
Given that, according to scientists, the merger happened 7 billion years ago, it is possible that we are talking about a “primordial black hole” – a hypothetical type of black hole that formed in super-dense matter at the time of the initial expansion of the universe.
