它可以产生与万有引力相反的斥力，产生大爆炸中的暴涨，随后使宇宙产生更为平稳的加速度，这种加速度归因为暗能量。
It can produce repulsive gravity to drive cosmic inflation in the big bang, while later on it could generate the more sedate acceleration that is ascribed to dark energy.
作为一个类比，就像在形成万有引力定律之前，必须有“加速度”和“重力”的概念，而且必须有对这些概念的广泛接受的度量方式。
As an analogy, before a law of gravitation could be formulated, it was necessary to have the concepts of 'acceleration' and 'weight,' and there had to be commonly accepted measures of these terms.
加速度和万有引力作用之间的等效性，意味着我们可以通过记录万有引力的作用来研究加速度对于时间的作用。
This equivalence between acceleration and gravity means that we can investigate the effect of acceleration on time by noting what effect gravity has.
