我们以往对宇宙膨胀的认识很可能是错误的。近日,天文学家获得了最精确的宇宙膨胀速度的测量值,而这个结果比预期快了8%。如果这一发现得到进一步证实,那么将彻底改变我们对暗物质和暗能量的理解,以及对宇宙本身的理解。在公认的宇宙论模型中,宇宙的进化受到暗物质与暗能量之间竞争作用的影响。暗物质的引力倾向于减缓宇宙膨胀,而暗能量则在相反的方向推动宇宙加速膨胀。
Our past knowledge of the expansion of the universe is likely to be wrong. Recently, astronomers have obtained the most accurate measurements of the rate of expansion of the universe, and the result was 8% faster than expected. If this finding is further substantiated, then our understanding of dark matter and dark energy and our understanding of the universe itself will be radically changed. In the universally accepted cosmological model, the evolution of the universe is influenced by the competition between dark matter and dark energy. The gravitational pull of dark matter tends to slow the expansion of the universe, while the dark energy drives the universe to expand in the opposite direction.
