Scientists Unveil the Number of Black Holes in the Universe – You Won’t Believe What They Found

Black holes are mysterious and fascinating cosmic structures that have fascinated scientists for centuries. Although we lack an in-depth understanding of them, recent research has shed light on their number and distribution in the observable Universe.

A team of scientists from SISSA–Scuola Internazionale Superiore di Studi Avanzati or International School for Advanced Studies–has recently calculated the number of Black Holes in the observable Universe: 40 billion billions. The researchers examined the demographics of stellar-mass black holes, which are black holes with masses between a few to some hundred solar masses, that originated at the end of the life of massive stars. They found that around 1% of the overall ordinary (baryonic) matter of the Universe is locked up in stellar-mass black holes.

In collaboration with Dr. Ugo Di Carlo and Professor Michela Mapelli from the University of Padua, the team also explored the various formation channels of black holes of different masses, such as single stars, binary systems, and star clusters. The research has shown that certain events are needed to explain the mass function of merging black holes as estimated from gravitational wave observations by the LIGO/Virgo team. Black holes remain a source of fascination and mystery for scientists. We know that they are located in galaxies throughout the Universe, but we still lack a complete understanding of their properties and behavior.

The recent findings from SISSA are a great step forward in our quest to unravel the mysteries of these cosmic structures. The research also opens up new possibilities for scientists to study and explore black holes, such as the possibility of using them as tunnels in space, allowing us to easily reach unimaginable distances. The discovery of the number of Black Holes in the observable Universe is an incredible achievement and will no doubt provide a great platform for scientists to continue to unravel the mysteries of these enigmatic cosmic structures.
