Gzk bound
Webray events with higher energies than the GZK bound, i.e. violating the bound. Convert the mean free path given above to more reasonable cosmological units (i.e. pc, kpc or Mpc). Brie y discuss at least two possible qualitative ways how cosmic rays observed on Earth could evade the GZK bound. Feel free to google for \inspiration".

What is the average energy of the photons in outer space (in electron volts)? b) How much energy would a proton (p) need to collide with a photon ( γ) in outer space to convert it to a 140 MeV pion ( π0)? That is, what is the energy threshold for p+ γ→p+ π0?
