晚期宇宙加速的巧合问题对我们对宇宙演化的理解构成了一个严重的谜题。在这里，我们认为这个问题可能有一天会得到解决——或者更好地理解——通过将哈勃膨胀率表示为密度（暗物质/暗能量）之比的函数，并通过观测确定红移的速率。
The coincidence problem of late cosmic acceleration constitutes a serious riddle with regard to our understanding of the evolution of the Universe. Here we argue that this problem may someday be solved - or better understood - by expressing the Hubble expansion rate as a function of the ratio of densities (dark matter/dark energy) and observationally determining the said rate in terms of the redshift.
