特别广播英语第 127 课：Black Holes 黑洞-3

In some binary systems, astronomers have shown that there is an invisible companion star, a "partner" to the one which we can see in the sky. 在一些双星系里，天文学家已经表示这里有一颗看不到的伴星，即我们可以在天空中看到的一颗星球的伙伴。

Matter from the one which we can see is being pulled towards the companion star. 来自我们的看到的星球的物质正被吸引到伴星去。

Could this invisible star, which exerts such a great force, be a black hole? 这颗产生如此巨大力量的看不见的星球会是黑洞吗？

Astronomers have evidence of a few other stars too, which might have black holes as companions. 天文学家还有其它一些星球的证据，这些星球可能与黑洞相伴。

The story of black holes is just beginning. Speculations about them are endless. 对黑洞的研究刚刚开始，各种推测会层出不穷。

There might be a massive black hole at the center of our galaxy swallowing up stars at a very rapid rate. 在我们银河系的中心很可能存在着一个巨大的黑洞正以极快的速度吞食着星球。

Mankind may one day meet this fate. On the other hand, scientists have suggested that very advanced technology could one day make use of the energy of black holes for mankind. 人类有一天也会面临被吞食的命运。而科学家提出，有一天高科技利用轩洞的能量为人类服务。

These speculations sound like science fiction. But the theory of black holes in space is accepted by many serious scientists and astronomers. 这些设想听起来像科幻小说，但空间中黑洞的理论被许多严谨的科学家和天文学家接受。

They show us a world which operates in a totally different way from our own and they question our most basic experience of space and time. 他们向我们展示了一个以完全不同于我们理解的方式运行的世界，并对我们最基本的时空经验提出了疑问。
