论文摘要
逻辑模型[P.H. Chavanis，Eur。物理。 J. Plus {\ bf 130}，130（2015）]可能是$λ$ CDM型号的有趣替代方法。它能够说明宇宙的当前加速扩展，同时求解CDM模型的Core-Cusp问题。在逻辑模型中，有一个深色流体。它的休息质量起着暗物质的作用，其内部能量起着暗能量的作用。我们重点介绍了逻辑模型的两个显着预测。它产生的深色光晕，通用表面密度等于$σ_0^{\ rm th} = 0.01955 c \sqrtλ/g = 133 \，m _ {\ odot}/{\ odot}/{\ rm pc}^2^2^2 $，与观察价值$ nmentation $ nmentional Contect obs} = 141 _ { - 52}^{+83} \，m _ {\ odot}/{\ rm pc}^2 $。它还可以预测，黑物质的当前比率为纯数$ω_ {\ rm de，0}^{\ rm th}/ω_ {\ rm dm，0}^{\ rm th} = e = e = 2.71828 ... $在非常符合观察的情况下，给出了$ω_ { obs}/ω_ {\ rm dm，0}^{\ rm obs} = 2.669 \ pm 0.08 $。使用baryonic物质的当前比例$ω_ {\ rm b，0}^{\ rm obs} = 0.0486 \ pm 0.0010 $，我们发现深色和暗能量的当前比例为$ω_ {\ rm dm dm，0}^{\ rm dm，0}^{\ rm rm th} = \ frac {1} {1+e}（1-ω_ {\ rm b，0}）= 0.2559 $和$ω_ {\ rm de，0}^{\ rm th} = \ rm th} = \ frac {e}使用观测值$ω_ {\ rm dm，0}^{\ rm obs} = 0.2589 \ pm 0.0057 $和$ω_ {\ rm de，0}^{\ rm obs} = 0.6911 = 0.6911 \ pm 0.0062 $在错误栏内。这些理论预测是通过提倡神秘的强大宇宙巧合（称为“黑魔法”）来获得的，这意味着我们的时代在宇宙的历史中起着特殊的作用。
The logotropic model [P.H. Chavanis, Eur. Phys. J. Plus {\bf 130}, 130 (2015)] may be an interesting alternative to the $Λ$CDM model. It is able to account for the present accelerating expansion of the universe while solving at the same time the core-cusp problem of the CDM model. In the logotropic model, there is a single dark fluid. Its rest-mass plays the role of dark matter and its internal energy plays the role of dark energy. We highlight two remarkable predictions of the logotropic model. It yields cored dark matter halos with a universal surface density equal to $Σ_0^{\rm th}=0.01955 c\sqrtΛ/G=133\, M_{\odot}/{\rm pc}^2$ without free parameter in very good agreement with the observational value $Σ_0^{\rm obs}=141_{-52}^{+83}\, M_{\odot}/{\rm pc}^2$. It also predicts the present ratio of dark energy and dark matter to be the pure number $Ω_{\rm de,0}^{\rm th}/Ω_{\rm dm,0}^{\rm th}=e=2.71828...$ in very good agreement with the observations giving $Ω_{\rm de,0}^{\rm obs}/Ω_{\rm dm,0}^{\rm obs}=2.669\pm 0.08$. Using the measured present proportion of baryonic matter $Ω_{\rm b,0}^{\rm obs}=0.0486\pm 0.0010$, we find that the values of the present proportion of dark matter and dark energy are $Ω_{\rm dm,0}^{\rm th}=\frac{1}{1+e}(1-Ω_{\rm b,0})=0.2559$ and $Ω_{\rm de,0}^{\rm th}=\frac{e}{1+e}(1-Ω_{\rm b,0})=0.6955$ in very good agreement with the observational values $Ω_{\rm dm,0}^{\rm obs}=0.2589\pm 0.0057$ and $Ω_{\rm de,0}^{\rm obs}=0.6911\pm 0.0062$ within the error bars. These theoretical predictions are obtained by advocating a mysterious strong cosmic coincidence (dubbed "dark magic") implying that our epoch plays a particular role in the history of the universe.
