From the scientific point of view, the main problem is a lack of knowledge. Despite many hundreds of well-functioning nuclear power plants, our understanding of nuclear forces is only empirical, and empirical knowledge is always imperfect.
但在获取这些资源方面的进展却异常缓慢。从科学家的角度看来，主要的问题就是知识的缺乏。尽管已经有数百座核电站在成功运作着，我们对核能的理解其实还只停留在观察实验层面上，而用这种方式所得到的知识往往是不完整的。
