Dark matter is the low-energy tail of a neutrino-antineutrino plasma

Dark matter is the low-energy tail of a neutrino-antineutrino plasma that permeates the observable universe. Existence of this plasma is consistent with the short range r_W of the weak force, with boson masses m_Z and m_W, and with the previously unexplained values of the cosmological constant Λ, Higgs boson mass m_H, and other mysteries. The plasma has pressure sufficient to slow the acceleration of the cosmic scale factor.

Neutrinos in the plasma follow a Fermi distribution. Those in the low-energy tail of the distribution move slowly enough to be trapped in gravity wells. We show how their number density follows from properties of neutrinos and of the plasma, and how plasma pressure increases their effective gravitational mass. The resulting gravitational density at the sun's galactic radial distance matches the observed density of dark matter at that location.

Plasma neutrinos are hard to detect. Each has spin and electro-weak charge. This creates a magneto-weak moment for each neutrino. In the plasma, these moments spontaneously align, creating a low-energy state with large binding energy (~10¹⁶ eV). As a result, the plasma neutrinos, including the low-speed ones that constitute dark matter, cannot interact with matter and we cannot yet directly detect them.
