One of the most poetic and perspective-giving phrases belongs to Carl Sagan: "The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of star stuff." But not only are we made of star dust; we're made of elements so fundamental to the universe they were created in the first moments of the Big Bang. The history inside of us stretches back further than we knew and our future remains inescapably among the stars.
