There are many evaluates of the number of stars in the universe. One evaluate is that there are 1010 stars in the Milky Way galaxy, and that there are 1010 galaxies in the universe. Assuming that the number of stars in the Milky Way is the average number of stars in a galaxy, evaluate how many stars there are in the universe. It perhaps goes without saying.
