Buffy Posted February 14, 2008 Report Posted February 14, 2008 Welcome to Hypography! The answer is basically that what's on the CD is only the "model" or "shape" of energy that existed in the past: its not the energy itself. When you play the CD, you still need a battery or a wall socket to recreate that energy and the information that's on the CD is used as a guide as to how to build it so it makes the sounds you want. I won't get into the information entropy aspect of this unless you really want it (and that's a good topic for a new thread!). How did you find us? Have fun!Buffy Quote
