We show that if Dark Matter is made up of light bosons, they form a Bose–Einstein condensate in the early Universe. This in turn naturally induces a Dark Energy of approximately equal density and exerting negative pressure. This explains the so-called coincidence problem.

毕竟没有巧合！

我们表明，如果暗物质由轻玻色子组成，它们会在早期宇宙中形成玻色-爱因斯坦凝聚体。这反过来又自然地引发​​了大约相等密度的暗能量并施加负压。这就解释了所谓的巧合问题。
