Only a few know the terrifying truth--an outcast Earth scientist, a rebellious alien inhabitant of a dying planet, a lunar-born human intuitionist who senses the imminent annihilation of the Sun.  They know the truth--but who will listen?  They have foreseen the cost of abundant energy--but... read more

Note: Asimov presents the story as numbered, out-of-order, sections. The following synopsis tells the story chronologically.

In Part I, Frederick Hallam discovers a sample of tungsten that has become plutonium 186. Since plutonium 186 cannot exist under the physical constraints of this universe (it decays to tungsten), he deduces that there is a parallel universe where tungsten decays to plutonium 186. He essentially discovers an endless supply of cheap energy, which is extracted via the Electron Pump. Lamont, a scientist writing the history of the Electron Pump, proposes that the existence of the Pump is mainly due to the efforts of the para-men, and Hallam ruins his career. Lamont and Bronowski, a linguist, set out to prove that the Pump is potentially dangerous. They do find some evidence, but no one wants to believe them.
In Part II, In the parallel universe, we learn about Tritt, Dua, and Odeen, a triad of Soft Ones. Odeen is a left/Rational, Tritt a right/Parental, and Dua a mid/Emotional. Together, they occasionally 'merge' (Asimov's famed description of alien sex). Dua discovers the dangers of the Electron Pump for the humans, but the Hard Ones, the mentors of the Soft Ones, reason that they need the energy too much to save Earth. The triad decides to fuse (the final melt) in order to exert influence over the other Hard Ones, but Dua realizes, in the process, that they will become Estwald, the inventor of the Pump.
In Part III, Denison, Hallam's rival, has discovered the danger of the Pump and a solution (with the help of Selene Lindstrom): tapping into another universe, a cosmic egg (cosmeg). Denison and Selene also foil a plot to take the moon out of orbit using the cosmeg pump.

Quotes edit see section history

  • “Against stupidity, the gods themselves contend in vain.”
    Myron Brownowski, quoting Friedrich Schiller
  • “Denison never forgot that moment for it was his own remark that drove Hallam to the Nobel Prize and himself to oblivion.”
  • “Shall I demand every man give up the personal comfort and affluence he has learned to get used to, thanks to the Pump, just because one man cries 'Doom' while all the other scientists stand against him, and the revered Hallam calls him an idiot? No, sir, I will not go down in flames for nothing.”
    Senator Burt, to Peter Lamont
  • “"We lack the authority to make any such statement.""Yes, but they won't know, and in the end we'll be mankind's heroes.""Even if they execute us first?""Even so ... It's in your hands, Mike, and I'm sure it won't take much longer."”
    Peter Lamont and Myron Brownowski
