Google has no reference to Kugelneutrino until this will be indexed. Okay.
I wonder if a Kugelneutrino exits. Enough supernovas, maybe a million, spaced on a large sphere, igniting simultaneously for a sphere centered observer, would send a lot of neutrinos in all directions. In the sphere center their combined mass should stop them making a Kugelneutrino.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
