摘要：

Should dark energy decay predominantly into active neutrinos in similar to 60 Gyr, their mutual annihilation within iron-cored oceanic planets might give rise to attractive habitats for aquatic life persisting upward of 10 25 years. Neutrino haloes of density exceeding similar to 1 pg.km(-3) could efficiently maintain liquid oceans beneath thermally insulating layers of floating ice. Iron's hcp -> fcc phase transition constitutes a mechanism for regulating neutrino annihilation, capable of achieving a remarkably consistent heat flux through the oceans almost irrespective of planet size. Heavier sterile neutrinos may presently account for a good share of dark matter and could catalyze planetary heating as active haloes become depleted. Given the impressive energetic efficiency of the arrangement, if extraterrestrial civilizations are acquainted with this knowledge, they may possess a universal outlook distinctly different to ours involving a harmony between the physical and life sciences. Three resolutions of the Fermi paradox then emerge, novel explanations for extraterrestrial silence yielding falsifiable predictions concerning particle physics. It is conceivable that improved knowledge of the properties of active and sterile neutrinos might soon herald a new dawn in cosmology. (C) 2015 Physics Essays Publication.
