The top five elements in the barren sky of the universe are the same top five elements in the human body (minus helium). One day, far, far from now, the earth will cease being. One day, when your body has rotted into and become one with the earth or your ashes have become lost among the world, that world will explode into the space around it. The fiery rocks and shining chunks of mass that used to be the ground you walked on and the buildings you lived in and the friends you loved will scatter themselves into the universe and make themselves into thriving, shining stars that can be seen from galaxies away. They’ll shine in our definition of forever. One day, you’ll shine forever. One day, you’ll be stardust.
