@forallcurious Possibility of Cold Neutrino Ejection from Black Holes & Dark Matter Production
Touches many active areas of theoretical physics — primordial black holes (PBHs), Hawking radiation, sterile neutrinos, dark matter — not a standard model prediction but theoretically possible...
@forallcurious These emissions could be sterile neutrinos interacting weakly with Standard Model sector.
Sterile neutrinos produced at low energies (cold) may escape observable universe w/o interacting, invisible to current detectors.
Sterile neutrino dark matter candidates evade detection.
@forallcurious PBHs slowly evaporate, releasing low-energy particles which are dark matter candidates (sterile neutrinos, axions) remaining in a separate “dark sector” or extra dimension.
PBHs may undergo final explosive bursts (Hawking explosion) producing high-energy particles & dark matter.
@forallcurious PBHs as white holes emitting matter & energy rather than absorbing are speculative.
SP says: black holes =/= white holes;
yet models predict final evaporation phase resembles white hole event horizon, ejecting particles in burst, explaining rare, high-energy neutrino detections.
@forallcurious If cold neutrinos are:
Sterile neutrinos (no weak force rx),
Produced in a hidden sector or extra dimension,
Emitted at energies too low to trigger Standard Model interactions,
**They are invisible to current neutrino telescopes. remaining unseen in our “temporal universe.”**
@forallcurious Theories linking PBHs to sterile neutrinos and dark matter are testable:
Future high-altitude neutrino detectors (planned balloon-based projects) search for low-energy sterile neutrino signals.
Observations of rare high-energy neutrino events may mirror PBH evaporation models.
@forallcurious If PBHs are dark matter, distribution & evaporation signatures are constrained by astrophysical observations.
Consistent with extensions of PBH physics, sterile neutrino dark matter models, extra-dimensional theories.
A plausible “what if” to be explored in the coming years.
