"The Unwritten Sequel

Foundation and Earth takes place only some 500 years into the 1,000-year Seldon plan. The ending hints greatly at the next part of the story. As detailed by his wife in It's Been a Good Life, Asimov intended to write a sequel, but his attempts were fruitless. He did not know what to do next. This is why he wrote the prequels (Prelude to Foundation and Forward the Foundation) instead.
Trevize mentions that no human ship has ever penetrated the Magellanic Clouds, nor the Andromeda Galaxy or galaxies beyond that. Intelligent aliens have been mentioned in the short story Blind Alley. No reason is given why humans have not visited other galaxies, which would seem to be within range of the hyperspace drive.
The book states several times that the Seldon plan does not take into account alien influences. Combined with the ending (see above), one could surmise that for the sequel, he planned to introduce aliens (almost certainly from another galaxy) who would upset and possibly destroy the Seldon plan. It is also possible that Fallom, combined with Daneel's vast knowledge and influence, but uninhibited by the Three Laws of Robotics, would have turned out to be the enemy of humanity (as the last two paragraphs seem to suggest). However, all his fictional citations from the Encyclopedia Galactica are dated after the formation of the Second Galactic Empire. This meant that there could never be irreparable damage to the plan, since, eventually, it must return to its precalculated path."
