Physicists have detected an amazing variety of energetic phenomena in the universe, including beams of particles of unexpectedly high energy but of unknown origin. In laboratory accelerators, we can produce beams of energetic particles, but the energy of these cosmic rays far exceeds any energies produced on Earth. So my question is, from where do these ultra-high-energy cosmic rays come from?
