Just for the record.
Volume of a sphere: 4.19 x radius cubed.
Why is the night sky not filled to the brim with stars? Because there has not been enough time for the light from all stars to reach us. In the event that enough time would have passed the night sky would be brilliant with the light of myriad stars.
The number of stars increases with distance cubed -- but star brightness fades with distance squared.
