Stardust

Tonight I learned that gold is star dust! I love the History channel program "How the Earth Was Made". So much new stuff to learn. Anyway, I always assumed that gold was just an element of the earth. But it turns out it was created by an exploding star, a huge supernova that rained gold particles through the universe. When the earth formed, some of the particles were captured. Gold always stays gold. It doesn't change, like iron turns into rust or uranium decays into lead. So the gold on your finger came from a faraway star, billions of years ago. That's even more enduring than diamonds made from coal. Who said diamonds are forever? Awesome.
