On the one hand... In my defense, I was just suggesting neutrinos as an alternative, mainly that they could penetrate just about anything without being significantly attenuated. I didn't mean to sound as if I was suggesting that they go FTL. On the other hand... the electron-neutrino does some silly things. http://www.npl.washington.edu/AV/altvw54.html Yeah, it's old. It's still possible. Forward had some things to say about the electron neutrino as well. On the tail... there's a funny kink in the cosmic ray spectrum. http://arxiv.org/abs/astro-ph/9904290 http://arxiv.org/abs/hep-ph/0009040 Might be that this will all come to nothing. But if the particle zookeepers can keep screaming that the Higgs is the messiah, I reckon I can have some fun too. ;-> --Kyle
