Source sentences:
text: So if cosmic rays were given an initial energy greater than that, they would lose energy in repeated collisions with the cosmic microwave background until their energy fell below this cutoff.
text: Cosmic rays that lose their energy or leak out of the Galaxy have to be replenished.
text: Above this limit, it is thought that cosmic rays interact with the cosmic microwave background to produce exotic particles called pions, thereby lowering their energy to the GZK limit.
text: The Answer Theoretically, cosmic rays with energies above 1020 electron volts should rapidly lose their energies by interacting with the cosmic microwave background photons.
text: They will also experience gradient and curvature drifts (Isenberg & Jokipii 1979) and will be convected back toward the boundary by the solar wind and lose energy through adiabatic cooling, although the latter process is only important below a few GeV and does not affect ground based observations.
