Far future in science fiction and popular culture

The far future, here defined as the time beyond the 10th millennium, has been used as a setting in many works of fiction or popular scientific speculation.

The British science fiction series Doctor Who has featured many events beyond the 10th millennium AD due to time travel being a key aspect of its format:

Frank Herbert's Dune series spans thousands of years of distant future history in a galactic, and eventually multigalactic, setting, describing an interstellar feudal system enabled by a prescience-imbuing drug known as the spice.

Isaac Asimov's Foundation series, comprising the union of his Robot novels, Galactic Empire novels and Foundation novels, describes a future history of humanity from 1996 to tens of thousands of years from now. The 11th millennium occurs after the end of the Robot stories.

The Future is Wild was a speculative documentary hypothetising how life could evolve over the course of millions of years:

Olaf Stapledon's novels Last and First Men and Star Maker are speculations on the evolution of intelligence in the universe. Last and First Men explores the future evolution of intelligence on Earth, while Star Maker explores the technological and social changes undergone by various alien species.

Isaac Asimov's short story "The Last Question" charts the future evolution of Man as subsequent generations ask ever-more complex computers the same question: "Can entropy be reversed?" The story begins in 2061, when the supercomputer Multivac is asked the question and responds: "INSUFFICIENT DATA FOR MEANINGFUL ANSWER". The story then jumps forward to an unspecified time at least a thousand years later, in which a spaceship-borne computer is asked the same question, and gives the same answer.
