Yeah, such a measurement is extraordinarily unlikely. Neutrinos are extremely hard to detect, but the thing is there are different temperatures of neutrinos, and their detectability scales extremely non-linearly with temperature. Even with extremely high energy/temperature neutrinos from supernovae or stellar fusion we still only detect the faintest fraction of the vast quantity that flows through the detectors. The CNB is at a temperature of only a few Kelvin, and is made of extremely low energy neutrinos that are effectively impossible for us to detect, let alone study with current technology.
- dice 11y agoIt is something being worked on, though [0]. Extremely difficult does not equate to impossible :) 0: http://arxiv.org/abs/1504.03966 http://arxiv.org/abs/1504.03966
- InclinedPlane 11y agoThat's why I said "effectively" impossible. There are so many orders of magnitude between what we can detect and what would be needed to study the CNB. It's hard to have hope that we'll ever be able to overcome that, though it'd be awesome if we could.
