Are there black holes with masses greater than 50 suns? Yes, and scientists point out that this responds to that they grow along with the expansion of the universe.
A team of researchers from the University of Hawai’i at Mānoa, the University of Chicago and the University of Michigan in Ann Arbor published a paper that shows that masses of large and small black holes can result in one way: they gain mass through starting from the expansion of the universe itself.
NASA (National Aeronautics and Space Administration, in Spanish) describes a black hole as an astronomical object with a gravitational force so strong that nothing, not even light, can escape from it.
The two main classes to study are those of stellar mass and the supermassive. Those of stellar mass, three to dozen times the mass of the Sun, are those that extend through the Milky Way, while the supermassives that weigh between 100 thousand to thousand of millions of solar masses are found in the centers of the majority. of large galaxies.
In this research, published in Astrophysical Journal Letters, the birth, life and death of millions of pairs of large stars were simulated. Those pairs in which both stars died to form black holes were related to the size of the universe.
In that sense, as the universe continued to grow, their masses also increased.
Although there is no scenario capable of explaining the diversity of mergers observed so far, this article is one of the first to make this point.
The LIGO and Virgo observatories have found many black holes as massive as 100 suns, likewise black hole mergers are perceived through the emission of gravitational waves.
“A stellar-mass black hole forms when a star of more than 20 solar masses exhausts the fuel in its core and collapses under its own weight,” explains NASA.
This collapse triggers a supernova explosion.
