The concept, understanding, idea, and/or knowledge that the Earth is a tiny mote of dust traveling around a medium-sized star on a spiral arm of the Milky Way galaxy with around 100 billion other stars in the galaxy, and there are 100 billion other galaxies (all with about 100 billion stars in each of them) in the Universe. Yet, the atoms that comprise life on Earth were forged in the center of a massive star that had to explode for us to live. We are seemingly insignificant, but very special at the same time, for we are literally star stuff.
