From the Ted Talk by Garik Israelian: How spectroscopy could reveal alien life

Unscramble the Blue Letters


Now to go ahead with this, we really need to understand chemical evolution of the universe. It's very complicated. I don't really want you to try to understand what is here. (Laughter) But it's to show you how cpoceailmtd is the whole story of the production of chemical elements. You have two channels — the msisave stars and low-mass stars — producing and rnccelyig matter and chemical elenmets in the universe. And doing this for 14 billion years, we end up with this pcuitre, which is a very important graph, showing relative abundances of chemical elements in sun-like stars and in the interstellar medium.
