A team of astrophysicists have developed a method of estimating the number of stellar-mass black holes, and that number is massive. They estimate that while these black holes only make up 1% of all normal matter, there are an astounding 40,000,000,000,000,000,000 (40 quintillion) of them.

Teams at NASA continue to align the mirrors of the
