A long time ago, Stephen King discussed one of his science fiction short stories. I believe it was The Jaunt or possibly another story from Skeleton Crew. I do not remember where I read the discussion.
King said that he originally tried to get the story published in a science fiction magazine that was more prominent than the one that eventually published it. But the prominent magazine rejected the story because one of the elements of the story was totally unbelievable in terms of the science (he mentioned what it was, but I don't remember it). He said he agreed with them and that he should have changed that aspect of the story.
Does anyone know which story this is, and what aspect of the story caused it to be rejected?
