The record energy for a cosmic ray particle (probably a proton) was detected in 1991 with a energy of 3*10^11 Gev, that's 40 million times as much energy as what he LHC in Switzerland can produce. We can only speculate on how it was made but we do have some idea where and when. According to something called the CZK limit cosmic rays with energy greater than 5*10^10 Gev can't be coming from a place further away than 160 million light years because if they were then interactions with the cosmic microwave background radiation would slow them down and rob them of energy. Cosmically speaking 160 million light years is pretty close and 160 million years is pretty recent. > The only place I can think of that might produce that kind of energy is > approaching the singularity of a black hole. Or maybe the decay product of some very exotic particle unknown to science was made in the first nanosecond after the Big Bang and has only decayed recently into a super fast ultra energetic proton. Or maybe it came from something even stranger. John K Clark -- You received this message because you are subscribed to the Google Groups "Everything List" group.
