The known (non-sterile) neutrinos are very light, but there's no particular reason a hypothetical sterile neutrino would be.You can cook up sterile neutrinos with very large masses if you want to https://arxiv.org/abs/1303.6912

Sterile neutrinos could also be a lot heavier than regular neutrinos, those kind of sterile neutrinos are ideal candidates for explaining dark matter and the matter-antimatter asymmetry https://arxiv.org/abs/1303.6912 Just as I am disappointed that "global warming" changed into the more ambiguous "climate change", I'm a little disappointed that the "right-handed neutrino" has turned into the "sterile neutrino". It's really strange that we only observe left handed neutrinos and either the revelation that there is a hidden right-handed neutrino or that neutrinos are fully Majorana particles…

One interesting thing about muon accelerators is that they could produce enough neutrinos to be dangerous: https://accelconf.web.cern.ch/p99/PAPERS/WEBR6.PDF which might be a good thing in that the neutrino mass is a "missing part of the standard model" as opposed to "possible physics beyond the standard model". The neutrino mass term could explain dark matter, dark energy and the matter-antimatter asymmetry https://arxiv.org/abs/1303.6912 whereas a Higgs Factory or top factory seems likely to be a big disappointment because all the evidence we have is that the Higgs field is as simple as it…

I think the big theme around Webb is that certain events seem to have happened much more quickly in the early universe than we can explain. It's at the point that it is a crisis in astronomy and not just an "improvement in knowledge". For a long time it has been a big mystery how the supermassive black holes formed at galactic centers, it is not clear at all how they got so big so fast. In recent observations it seems that many other processes happened much more quickly than we expected so either we're going to understand how things happened so fast or maybe what we think was the first…

I am not an expert (I am a condensed matter physics PhD who doesn't work in the field) but I believe the dark matter particle is a right-handed neutrino. My argument is that the neutrino obviously has a mystery left in it because we don't know what the mass term looks like. It is not "physics beyond the standard model" but "a missing piece of the standard model". This nice paper makes the case that the right handed neutrino could wrap up the remaining mysteries in particle physics https://arxiv.org/abs/1303.6912

What I like of the right-hand, left-hand split is that it emphasizes the mystery of neutrinos. We know neutrinos have a mass, we don't know how much. We don't know how to incorporate the neutrino mass into standard model. Other fermions come in left-handed and right-handed forms but we only see left-handed neutrinos. One idea is that right-handed neutrinos do exist but are highly elusive. In fact they are a good answer to the dark matter and other physics mysteries https://arxiv.org/abs/1303.6912v3
