Dr. Steven Sorenson plans to tap the geothermal energy of the Earth's interior by means of a thermonuclear device detonated deep within the Earth. Despite dire warnings by fellow scientist Ted Rampian, Dr Sorenson proceeds with the experiment after secretly learning that he is terminally ill. This experiment causes a crack to form and grow within the earth's crust, which threatens to split the earth in two if it is not stopped in time. 　　译文(2): 史蒂文 · 索伦森博士计划利用在地球深处引爆的热核装置来开发地球内部的地热能。尽管同为科学家的泰德 · 兰皮安(Ted Rampian)发出了可怕的警告，索伦森博士在秘密得知自己已经病入膏肓之后，还是继续进行了这项实验。这个实验导致地壳内部形成裂缝并扩大，如果不及时阻止，地球就有可能被一分为二。
