But computer viruses...
Like religion, artificial life has evolved certain tenets. One is that lifelike behavior cannot be imposed from the top down. Rather, it emerges from the bottom up, like flocking among birds, when large numbers of parts obey a few simple rules. Another principle, derived from recent advances in the theory...

The collision of two accelerated particles releases enormous bursts of energy. But that energy instantly condenses into a new array of particles, some of which may not have existed...
