Would it be possible to eventually have structures made from neutrinos somewhere in the universe, as it is indicated in this question (Are neutrino stars theoretically possible?), like halos of neutrino gas surrounding the center of galaxies?

And if it would be possible, could they have high amounts of angular momentum?

  • $\begingroup$ I feel like the linked question still answers the first part of your question. That's it's still a plausible thing that could occur. $\endgroup$

  • $\begingroup$ Not an expert in neutrinos, but aren't right-hander neutrinos a candidate for dark matter? (Which does form halos and stuff) $\endgroup$

  • $\begingroup$ @Triatticus and about the second question, could these structures have high amounts of angular momentum? Is it physically possible? $\endgroup$

  • $\begingroup$ @NíckolasAlves yes, but right-handed neutrinos are hypotehtical. Could these structures be formed by the neutrinos we know for certain that do exist? $\endgroup$

  • $\begingroup$ I mean any structure will probably have angular momentum, I'm not sure what you distinguish as high angular momentum, it must stay bound so there is going to be some form of upper limit on it. $\endgroup$
