Are black holes infinite in the Universe

Many of you may have wondered something related to black holes, that astronomical object that has such a strong gravitational force that not even light is able to escape from it. One of the questions that may run through your head, surely, is the following: How many black holes are there in the universe ?

If a few years ago it was unthinkable to have this type of information about the universe and everything related to space, since it seemed only possible in science fiction movies or series, the truth is that a team of astrophysicists has managed to calculate the number of stellar-mass black holes that exist. Although, they have only been able to calculate the number of the observable universe . However, it is not the only question that you may have ever asked yourself, and that is if you had doubts about whether it has sound or not, NASA has shown how it sounds:

Although, the really important thing right now for many of you will be to know the total number of black holes that are in space. We already warned you that, although the number will surprise you, they are not the only ones in the entire universe.

The number of black holes in space

The team in charge of carrying out this research was a group of researchers from the Higher International School for Advanced Studies of Trieste, in Italy. In their study, they managed to calculate the closest number anyone had ever gotten: the number of stellar-mass black holes in the universe that can be observed.

In this case, we are dealing with holes that arise when very massive stars gravitationally collapse. According to this team’s research , it is estimated that there are 40,000,000,000,000,000,000. To give you a better understanding, there are 40 trillion (a billion times a billion on the long scale ) stellar-mass black holes .

And although this is a really high figure, the truth is that it is only equivalent to 1% of ordinary (baryonic) matter, that is, that normal matter, which is not dark or exotic, which makes up the planets and stars of the universe. In addition, they have calculated those that are within the sphere of about 90,000 million light years in diameter within the observable universe.

How could they calculate it?

First of all, keep in mind that a black hole is impossible to see, basically because its gravity is so high that it prevents light and radiation from escaping from it . It is only possible to observe those that are supermassive, that is, whose mass is equivalent to that of billions of suns.

In the case of stellar mass black holes they are totally invisible. However, this has not been an impediment for the research group in Italy. And it is that to discover the amount that exists they have not needed to see them, because they chose to track how the stars have evolved in the universe .

More than anything, they have estimated how often stars turn into black holes. To do so, they used a new method that combines the state-of-the-art binary and wake evolution SEVEN code with empirical prescriptions for relevant physical studies.
