VIVA – Scientists have no idea how to calculate the population black hole stellar mass scattered over universe, although it is difficult to know for sure.

A stellar-mass black hole is a massive, dead star. The number is quite astonishing, namely as many as 40 quintillion or 40,000,000,000,000,000,000 black holes, or about one percent of all normal matter in the observable universe.

“The innovative character of black holes is that they combine detailed models of stellar and binary evolution continued with star formation and metal enrichment in individual galaxies,” said astrophysicist Alex Sicilia of the International School of Advanced Studies, Italy.

Black holes are the big question marks that hang over human understanding of the universe.

But if humans have a good idea of ​​how many black holes there are in the solar system it can help answer some questions about it.

One of the approaches used by Sicilia and the research team is to estimate the history of massive stars in the universe, citing the site Science Alert, Thursday, January 20, 2022.

This knowledge may yield clues about the growth and evolution of the supermassive black holes millions or billions of times the mass of the Sun that form the galactic core.
