Gods themselves is a science fiction novel by isaac asimov, which tells that in the 22nd century, the earth can exchange materials with the parallel universe, and from then on, it has a steady stream of energy. But only a few people know the truth of the danger, an untrusted scientist on the earth, an alien on a planet whose energy is gradually exhausted, and a human being born on the moon with predictive ability. Only they know that mankind is about to pay a huge price for seemingly endless free energy.

Here are some classic quotations:

-Millions of novels can be read infinitely!

-In the face of ignorance, the gods themselves kept silent.

-Exactly, Montez said brightly, the moon colony is an island, the only island left in the pre-war earth civilization; In the great retrogression of human civilization, this is the last arrow to advance. That's so romantic, Montez. I don't think so. The earth is going backwards, human beings are going backwards, and only the moon people are still moving forward.
