Last, the existence of hidden particles identical to ours would have affected cosmic expansion; compositional measurements rule that out.

原因之三，如果有类似于我们世界的隐性粒子的存在，它们将影响宇宙膨胀，多种观测都证明这一点。

Ambitious future observers might also send out probes that escape the supergalaxy and could serve as reference points for detecting a possible cosmic expansion.

有企图心的未来观测者，或许会发射一些能够脱离超级星系的探测器，做为侦测宇宙膨胀的参考点。

Although the accelerating cosmic expansion came as a surprise to astronomers, its discovery provided an essential ingredient in what has become the prevailing cosmological model.

尽管宇宙加速膨胀对天文学家来说很惊讶，但是这个发现为主流宇宙学模型提供了一个基本要素。
