Every year 40,000 tons of cosmic dust falls onto Earth. Everything on Earth and in the universe originated from stardust. Our bodies are made of remnants of stars and massive explosions in the galaxy. We have particles in us as old as the universe, and then particles that landed here maybe only 100 years ago. Stardust continually floats through us and it directly connects us to the universe over and over rebuilding our bodies throughout our lifetime. Eternal reciprocity between the universe and us living creatures.
