浩瀚的宇宙高深莫测,无奇不有,其中最神秘的天体莫过于黑洞。这种“怪兽”比森林中的老虎更凶猛,不管是什么东西,一旦进入它的势力范围,都会被吞吃掉,连骨头也不吐出来。而且它还穿上了隐身衣,谁也看不见它,即使你用强光照射,用雷达探测,仍然找不到它的踪迹。这种“怪兽”就是爱因斯坦广义相对论预言的一种奇特天体。 The vast universe is unpredictable, and there are no wonders. The most mysterious object is the black hole. This kind of “monster” is more fierce than the tiger in the forest. No matter what it is, once it enters its sphere of influence, it will be swallowed and the bones will not spit out. And it also wears a cloak, and no one can see it. Even if you use bright light and use radar to detect it, you can’t find it. This “monster” is a strange object of Einstein’s general theory of relativity.
