Talk about how to confuse science... I was always under the impression Cosmic Rays refered to the part of the EM Spectrum with shorter wavelength than "Gamma Rays" or higher energy "photons"  (quanta of EMF pruduced by an event of short enough duration to cause the burst of EMF to present the characteristics of a packet of energy with some particle like characteristics) believed to be produced by "cosmic" events alone. NOT very high energy beta and alpha PARTICLE  events or antimatter particle events. To lump all these completely different events together as "cosmic ray data" will of course cast doubt on common theory since they are all theoreticly peoduced by very different sub-atomic events anyway!

Diluting Cosmic Ray definition to include accelerated free electrons and helium nuclei and other high energy particles will just confuse those trying to understand Astro-Physics, lay-person or students of the discipline itself alike!

i've always considered any rays entering our radiation belts from 'out there'as being of cosmic origin!
