cosmic expansion

In order to explain the present cosmic accelerating expansion some physicists think that the observed acceleration is a signal of breakdown of our understanding of the laws of gravitation and propose to modify the Einstein's gravity theory.

为了解释当今宇宙的加速膨胀，一些物理学家认为现有的引力理论在宇宙尺度上可能不成立，为此他们修正了爱因斯坦引力理论。

The simplest candidate of dark energy is the cosmological constant, which can explain the present cosmic accelerating expansion but at the same time it also leaves some theoretical problems unresolved.

暗能量最简单的候选者是宇宙常数，它虽然很好的解释了今天的宇宙加速膨胀但同时也存在一些需要解决的理论问题。

The quark forms matters, which are relatively dense at the early stage of the cosmic expansion, creating super massive stars that are beyond our imagination.

夸克结成物质，在宇宙膨胀的初级价段物质相对密集，生成了超出我们想象的超大质量恒星。
