Black holes are the most efficient power plants in the Universe. Fifty times more efficient than nuclear power, only one gram of matter falling toward a black hole every second could power the earth. Black holes are objects of infinite density surrounded by ghostly event horizons. An object wandering across the event horizon is swallowed and becomes lost to the universe forever. Not even light can escape. But how can power escape a black hole when nothing can escape it?

黑洞是宇宙中最有效的发电厂。 效率是核能的50倍，每秒只有一克物质落入黑洞，就可以为地球提供动力。 黑洞是被幽灵般的事件视界所包围的无限密度的物体。一个在事件视界上游荡的物体被吞噬，永远消失在宇宙中。 连光都逃不掉。 但是，当没有任何东西可以逃脱黑洞时，能量如何逃脱黑洞呢？
