"Let’s say there are 100 billion stars in our galaxy. And let’s say there are 100 billion galaxies in our universe. At any given moment, then, assuming ultra-massive and dwarf galaxies average each other out, there might be 10,000,000,000,000,000,000,000 stars in the universe. That’s 1.0 X 10 to the twenty-second power. That’s 10 sextillion. Here’s a way of looking at it: there are enough stars in the universe that if everybody on Earth were charged with naming his or her share, we’d each get to name a trillion and a half of them.
