Billions of years ago stars exploded and their debris spread out across the Universe where gravity pulled them into the gas clouds that eventually became the Earth. We are made of those atoms and elements. We are part of the Universe. So we owe our existence to the death of stars.
The tattoo is based on the traditional rose tattoo. The thorny stem of the rose is a protein chain of amino acids which when decoded into English spell out the letters "I AM STARSTUFF". I have incorporated someone else’s tattoo here and added it as the rose stem to my own exploding star design. A nicer polypeptide chain I never did see!!
