Yes, and there are also neutrino telescopes. I wait for the detection of an high energy neutrino event from beyond the CMBR. I think the opportunity, our understanding of physics and technology give us right now are immense. The fact that general relativity and quantum mechanics havent been reconciled by now only means that this is probably a very hard thing to do. But it doesn't mean that 'phyics is dead'.

- bacon_waffle 8y ago> I wait for the detection of an high energy neutrino event from beyond the CMBR My (non-physicist) understanding of this, is that neutrinos from then will be quite low energy now, due to the expansion of the universe(?), and so not detectable by the method IceCube uses. There is a minimum energy required, in part because the charged particles generated by the neutrino interaction need to be moving faster than the speed of light in water (or whatever the detection medium is) for there to be Cherenkov radiation generated and then detected. That said, I would love to see a response from a more knowledgeable person!
- whatshisface 8y agoThe neutrinos may start out with any energy, whatever produced them will determine that. To cross the great expanse of time and redshifting due to expansion and still have a lot of energy left, they would simply have to start out with a whole lot more. Any neutrino event that we could detect from that far away would probably be massive anyways, so maybe we'll see something.
