Guest guest Posted September 15, 2003 Report Share Posted September 15, 2003 The Cosmos is all that is, or ever was, or ever will be. We ourselves are made of starstuff. We embody the local eyes and ears and thoughts of the Cosmos. We are a way for the Cosmos to know itself. The same laws of nature determine the fall of an apple on Earth, the flight of an interplanetary spacecraft and the stately dance of galaxies billions of light years distant. The same chemical elements, the same laws of quantum mechanics apply everywhere in the Cosmos. These regularities are described by a mathematics as elegant and precise as a partita for solo violin by J.S. Bach. There are a hundred billion galaxies and a billion trillion stars. We witness a Cosmos resplendent with beauty and perhaps rippling with life -- an awesome reminder of the power and subtlety of the laws of nature and the triumph of cosmic evolution. These contemplations of the Cosmos stir us -- looking outward to the grandest of mysteries returns us to ourselves. As our understanding deepens, so does our awe. Science is a collective enterprise that binds the generations in an ongoing venture to discover the nature of the Universe. Our obligation to survive is owed not just to ourselves, but also to that Cosmos, ancient and vast, from which we spring. -- Carl Sagan (1934-1996), astronomer, philosopher and poet Quote Link to comment Share on other sites More sharing options...
