But if we did a little thought experiment -- as Einstein was very fond of doing -- we could imagine putting the Sun crushed down to six kilometers, and putting a tiny little Earth around it in orbit, outside of the black-hole sun.
但是，如果我们做了一些思想实验 – 爱因斯坦非常喜欢这样做 – 我们可以假想 把太阳粉碎后压缩在六公里的范围内， 然后在围绕它的轨道上放一个小小的地球， 比如放在离黑洞太阳 30公里远的轨道上。
