Cosmic ray showerstrack belonging to a charged particle was observed to split into two tracks. The observations of showers led to the development of the electromagnetic cascade theory in the 1930s with the participation of many of the famous physicists of the time. Towards the end of that decade Pierre Auger and coll

The end of the cosmic ray spectrum it ends or it continues forever to really huge energies. It seemed quite possible that there are showers of energy 10. eV and higher that cannot be seen only because of their very low flux. With a spectral index of 2.7 each higher decade of energy decreases the flux by a factor of 50. After the kne

High energy neutrino and gamma-ray astronomyt detected the neutrinos from SN 1987a and continuously monitors the emission of solar neutrinos in different energy ranges. Davis and Koshiba received the 2002 Nobel prize in physics for these observations.

Cosmic ray showers cascade theory in the 1930s with the participation of many of the famous physicists of the time. Towards the end of that decade Pierre Auger and collaborators discovered the extensive air showers . These are huge cascades initiated by particles of energy 10. GeV as estimated in that reference.

The end of the cosmic ray spectrumeen only because of their very low flux. With a spectral index of 2.7 each higher decade of energy decreases the flux by a factor of 50. After the knee, which has already been suggested, and the steepening of the spectrum each decade would decrease the flux by more than a factor of 100.
