| Aug 18, 2018 at 4:54 | comment | added | Magic Octopus Urn | I wonder if knowing the neutrinos current state along with approimations for the decay of neutrinos and state transitions over time could yield results. Sort of like how we study the decay of lead to identify the age of objects. | |

A second guy comes to help but after a while he asks: "are you sure this is where you lost your keys?". The first guy replies "no, i lost them over there, but the light is better here". I feel like this question deserves a better answer than "we can detect EM waves easier than neutrinos". | |
| Jun 12, 2018 at 20:53 | comment | added | dmckee --- ex-moderator kitten | @Mark But in 1987 we didn't have the infrastructure to get the direction data from the neutrino experiments to the traditional astronomy community in time for them to re-point any big scopes. We've got that now. (I was part of KamLAND for ~5 years.) | |
| Jun 12, 2018 at 20:37 | comment | added | Mark | @dmckee, we detected the neutrino pulse from SN 1987A a few hours before the visible light arrived. And to give an idea of how hard spotting neutrinos is, that "pulse" consisted of 25 neutrinos distributed between three detectors. | |
| Jun 12, 2018 at 19:52 | comment | added | dmckee --- ex-moderator kitten | In might be worth adding that Super-K has imaged the sun in neutrinos, but the poor angular resolution of the image suggests another problem with long range detection. Also that we doubtless detected the neutrino pulse from sn1987a, and that there is an on-going effort to detect supernova pulses in time to directed optical telescope to the right part of the sky in time to catch the first light. | |
