Cosmological neutrinos and anti-neutrinos are thought to have been created in the Big Bang in almost unlimited numbers. Being Fermions, they may condense into stable objects called Condensed Neutrino Objects (CNO). CNOs could be the Dark Matter everyone is looking for. Weak lensing data indicates that the degenerate neutrino mass (called the neutrino mass scale) $\sim 0.8$ eV/c². Being condensed degenerate matter, CNO have a maximum mass that can be sustained through internal momentum pressure, just as neutron stars and white dwarfs. We calculate this maximum mass, ${\mathcal{M}}_C$. We find that the critical radius for gravitational instability is 4.307$R_S$, independent of the value of the degenerate neutrino mass, where $R_S$ is the CNO Schwarzschild radius. CNOs accreting more mass than ${\mathcal{M}}_C$ become hyper-massive black holes (called in this paper ‘Ultra Black Holes-UBH’), where $M_{BH}\simeq 4\times 10^{17}{M}_{\odot }$. We discuss the origin of these objects, why they are x-ray quiet and why their discovery signature is the perturbation of the cosmological microwave background.

宇宙中微子和反中微子被认为是在大爆炸中创造的，数量几乎是无限的。作为费米子，它们可能会凝聚成称为凝聚态中微子物体（CNO）的稳定物体。CNO可能是每个人都在寻找的暗物质。弱镜头数据表明退化的中微子质量（称为中微子质量标度）$〜0。8$eV / c ²。作为凝结的简并物质，CNO具有可以通过内部动量压力维持的最大质量，就像中子星和白矮星一样。我们计算出最大质量${\mathcal{中号}}_C$。我们发现引力不稳定性的临界半径为4.307${\mathrm{[R}}_{\mathrm{小号}}$，与退化的中微子质量的值无关，其中 ${\mathrm{[R}}_{\mathrm{小号}}$是CNO Schwarzschild半径。CNO的质量比${\mathcal{中号}}_C$ 变成超大质量黑洞（在本文中称为“超黑洞-UBH”），其中 ${\mathrm{中号}}_{乙H}\simeq 4\times \mathrm{1个}{0}^{17}{\mathrm{中号}}_{\odot }$。我们讨论了这些物体的起源，为什么它们对X射线安静，以及为什么它们的发现特征是对宇宙微波背景的扰动。
