      These are highly interesting! the most I know (and understand) about them is their possible attribution to being caused by the decay of super-heavy dark matter. or possibly black holes… its actually something that people are still trying to work out!

      Sorry I dont know anything about them. Hopefully someone can give you an answer, and I’ll be educated too! 😀

      I think scientists are still trying to figure this out and the best way that we can measure them too. Hypotheses include the following: intergalactic shocks during galaxy formation, supernova, gamma-ray bursts or decay products of supermassive particles from galactic explosions. I have no idea though!

      Sorry – I know so little about this topic, but here’s a nice video on how cosmic rays help us to understand the universe:
