One of the most relevant and pressing questions in modern astrophysics and cosmology is: How many black holes are out there in the Universe? A recent study by the Italian research institute, Scuola Internazionale Superiore di Studi Avanzati (SISSA), has shed some light on this.
There are 3 million black holes in a megaparsec and the number of black holes in the universe is roughly six times the number of grains of sand on Earth.
