There are 40 quintillion black holes in our Universe

This is a huge number, I think this something like 40 10^24

or 40,000,000,000,000,000,000,000,000

Which is according to Scientists is the estimate of the number of black holes in the galaxy. The article on big think is here

This is why we use SI units and express huge numbers in powers. So 10^6 is a million or 1,000,000 for example.

It also makes it easier to multiply together as

10^6 x 1000 = 10^6 x 10^3 = 10^{6+3} = 1,000,000,000 or 10^9
