text: Why is it that some cosmic rays appear to possess energies that are theoretically too high, given that there are no possible near-Earth sources, and that rays from distant sources should have scattered by the cosmic microwave background radiation (more unsolved problems in physics)
text: X-rays and gamma rays are both types of high energy (high frequency) electromagnetic radiation.
text: Cosmic rays have been detected with very high energies, we believe that they originate from quasars and active galactic nuclei.
text: They are again thought to be produced within the Galaxy, but the energies are too high for them to be accelerated by the shocks of supernova remnants.
text: Unlike most particles, cosmic rays have extremely high energies and travel at extremely high speeds through space, nearly at the speed of light.
text: There is precious little evidence about the exact site(s) of cosmic-ray acceleration – cosmic rays being sped up to extremely high energies – above what the sun or the Milky Way can produce.
text: These energies are high enough the particles zip through the galaxy at two-thirds the speed of light or faster.
text: Unlike most particles, cosmic rays have extremely high energies and travel at extremely high speeds through space, nearly at the speed of light.
text: If the initial energy is high enough, this process may continue for many generations of interactions, resulting in a large burst of secondary particles reaching sea level.
