论文摘要
一般相对性允许宇宙常数（$λ$），从而激发了宇宙通胀和暗能量的模型。相反，我们表明$r_λ= \ sqrt {3/λ} $对应于事件范围：动作中的因果边界项。我们的宇宙正在其Schwarzschild Radius $ r_s = \ rl = 2gm $内部扩展，这可能起源于25 Gyrs以前的黑洞（BH）倒塌的均匀的质量$ m $云云。这样的BH宇宙允许大规模结构形成，而无需通货膨胀或暗能量。
General Relativity allows for a cosmological constant ($Λ$) which has inspired models of cosmic Inflation and Dark Energy. We show instead that $r_Λ= \sqrt{3/Λ}$ corresponds to an event horizon: a causal boundary term in the action. Our Universe is expanding inside its Schwarzschild radius $r_S=\rL=2GM$, which could have originated from a uniform free falling cloud of mass $M$ that collapsed as a Black Hole (BH) 25 Gyrs ago. Such a BH Universe allows for large-scale structure formation without the need of Inflation or Dark Energy.
