Interesting. It’s in fact impossible to visualize such a huge number.

But… Isaac Asimov once remarked that, at the present rate of population growth, if unchecked and with unlimited food resources, in 6000 years the mass of humanity would be equivalent to the entire mass of the universe. Which goes to show – we either control population growth, or billions are going to perish due to lack of resources.
