This is not the case according to general relativity.

但在广义相对论中可就不是这回事了。

The modern concept of a black hole comes from Einstein's theory of general relativity.

现在黑洞的理论来自于爱因斯坦的广义相对论。

General relativity says they might be possible, but that doesn't mean they have to exist.

广义相对论认为，虫洞是可能的，但不是说就一定会存在。

We've learned through special relativity and general relativity that different clocks tick at different rates.

我们学习了狭义相对论和广义相对论，不同的时钟以不同的速率行走。

Sure enough, the equations of general relativity predict a cosmic tug-of-war between gravity and expansion.

当然，广义相对论的方程式预测在引力和扩张之间 会发生宇宙拔河。

And yet when you try to combine quantum mechanics and general relativity, everything goes crazy.

然而，当你试图把量子力学和广义相对论结合起来时，一切都变得疯狂起来。

General relativity describes the behavior of very large things, while quantum physics explains the very small.

广义相对论形容的是巨大物体的行为，量子物理学解释的是微小物体的行为。

If Einstein is right, or if general relativity is correct, then the universe is expanding, yes?

如果爱因斯坦是对的，或者说广义相对论是对的，那宇宙是在膨胀的，对吧？

As weird science theories often do, this one starts with Albert Einstein's theory of general relativity.

和一些奇怪的科学理论一样，这个理论也来源于阿尔伯特·爱因斯坦的广义相对论。

And general relativity works perfectly to describe very big things like the motions of planets.

而广义相对论可以完美地描述非常巨大的东西，比如行星的运动。
