Let's Not
From Wikipedia, the free encyclopedia
Let's Not is a science fiction short story by Isaac Asimov. It was first published in Boston University Graduate Journal in December 1954. It was written for no payment as a favour to the journal, and later appeared in the collection Buy Jupiter.
Spoiler warning: Plot and/or ending details follow.
Two scientists, who have taken refuge below the surface of Mars together with a hundred others, discuss what Earth used to be like before it was destroyed by nuclear war. They hope to re-establish their teaching and in time repopulate the dead radioactive surface of Earth.
This very short story postulates a future in which Earth has been made radioactive and uninhabitable by nuclear war, and thus it may fit into the larger Foundation universe.
