This clip from "How the Universe Works" truly puts our size into perspective. When you think about the fact that there are over a hundred billion stars in our galaxy alone, you can realize how infinitely small we are. VY Canis Majoris is a billion times larger than our own sun. This means that it is 1000000000000000 times larger than Earth. A billion of something is more than the grains of sand we have on our own planet (to put such a number in perspective). This video is the epitome of our incredible insignificance, and is truly a humbling experience.
