| #7 We worked on this in the late 80's. How is "dark matter" new news? |

| #4 It might help to be clear. Low energy neutrinos from ordinary nuclear reactions are all over the place (e.g. from the Sun) and tend to zip right through the Earth and us without interacting. Most of the time. What they're talking about is ultra-high energy neutrinos, which actually have a fairly decent chance of interacting with us--which is how the big neutrino detectors like IceCube work. A neutrino interacts and produces a muon (if it was a muon neutrino) and the detector spots the Cerencov light from the muon's track and reconstructs the track to point it back to its source. (It's a lot harder with electron neutrinos or tau neutrinos--the pointing isn't nearly so good since they produce showers of particles.) What _makes_ these ultra-high-energy particles is still a question, though knowing _where_ they come from can help answer it. |

| #3 actually the majoritarian view is that neutrinos (there are more than one type) do have a mass however that mass is smaller than 1 millionth that of the electron so maybe 'near zero mass' |

| #2 We've discovered what's been known for decades! Yay us! Give us money! |

| #1 Sounds like they're on the verge of re-discovering flux and ether. |
