We are stardust. This is an awesome little planetarium show right in your hand. If you are interested in scientific factoids, join us at The Dome. Our guide is Amber, whom you will love. The scientific Creation scenario unleashes the universe in a burst oomef energy from a void of timeless darkness. About 13 billion years ago, the hot light of the Big Bang erupted, and separated itself instantly into matter and energy. The next 3 minutes of cooling precipitated all the atomic particles in the universe, in the unequal proportions of 75 percent hydrogen and 25 percent helium, plus minuscule traces of a few other elements. As the universe expanded exponentially in all directions and continued to cool, it shed no new light for at least a billion years, until it begat the stars, and the stars began to shine... New stars lit up by pressuring the hydrogen atoms deep within themselves to fuse with one another, yielding helium and releasing energy. Energy fled the stars as light and heat, but helium accumulated inside them, until eventually it, too, became a fuel for nuclear fusion, and the stars melded atoms of helium into atoms of carbon. At later stages of their lives, stars also forged nitrogen, oxygen, and even iron. Then, literally exhausted, they expired and exploded, spewing their bounty of new elements into space. The largest and brightest stars bequeathed to the universe the heaviest of elements, including gold and uranium. Thus the stars carried on the work of creation, hammering out a wide range of raw materials for future use...As the stars enriched the heavens that had borne them, the heavens gave rise to new generations of stars, and these descendants possessed enough material wealth to build attendant worlds, with salt seas and slime pits, with mountains and deserts and rivers of gold... ~Dava Sobel, The Planets~
