OXFORD – It was recently discovered that the universe’s expansion is accelerating, not slowing, as was previously thought. Light from distant exploding stars revealed that an unknown force (dubbed “dark energy”) more than outweighs gravity on cosmological scales.
发自牛津——最近有研究发现宇宙的膨胀速度并未减缓，而是如原先推导的那样逐渐加速。来自远方恒星爆炸所产生的光揭示出在宇宙学范畴内存在一种比引力更加强大的未知力量（人们称之为“暗能量”）。
