The Big Bang also predicts that in the early, hot universe, our fundamental forces may unify into one super-force.

在多重宇宙中， 永恒膨胀的惊人速度让我们没机会遇到 任何一个邻接的宇宙。

As you know, my field is evolution of the hot universe, the properties of the microwave background radiation, and theory of the black holes.

我的研究领域是热宇宙的演化，宇宙微波背景辐射的性质还有黑洞理论。

So it would make sense that the early, hot universe was originally opaque, until it cooled down to the point where it became transparent.

因此，早期炽热的 宇宙最初是不透明的，直到它冷却 到变得透明的程度，这是有道理的。
