According to astronomers, there are probably more than 170 billion galaxies in the observable Universe. Our Galaxy Milky Way contains up to 400 billion stars of various masses and brightnesses. There are spiral galaxies out there with more than a trillion stars, and giant elliptical galaxies with 100 trillion stars. And there are tiny dwarf galaxies with a fraction of our number of stars. So we will assume our galaxy to be an average galaxy. True or false?
