From: Charlie Crummer <crummer@AEROSPACE.ARPA> The 3 degree Kelvin background is universe-wide. Cosmic rays are charged particles or ions that get accelerated by some mysterious means or other (Maybe Uri Geller or something.). They have a spectrum of energies, of course, but some of them have truly large energies (like 10^20 Gev). Where a typical high energy event generated by an accelerator will have maybe 15 prongs, a typical cosmic ray may have over 100 daughter particles. --Charlie P.S. Cosmic rays are NOT the background radiation. --C
