Inspiration. Inspiration is the step where you decide what sort of character you want to play. I consider this the heart-strings step. You have found something you love to play, something you want to play.
In the end, it comes down to an estimate. In one calculation, the Milky Way has a mass of about 100 billion solar masses, so it is easiest to translate that to 100 billion stars. This accounts for the stars that would be bigger or smaller than our sun, and averages them out.Other mass estimates bring the number up to 400 billion.illions and billions of stars in a galaxy (after a quote often mistakenly attributed to Carl Sagan) is how many people imagine the number of stars you would find in one.
Cain starts with the estimate that on average, there are approximately 100 to 400 billion stars in a galaxy. There are estimated to be around 100 billion galaxies in our universe, which a means that a bit of large format Math tells us there are approximately 10 sextillion (10 billion, billion) stars in our universe.
