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:
- 12,005 AD: According to the episode "The End of the World", a new Roman Empire has been established on Earth by this year.

The Jagrafess is revealed to have been a pawn of the Daleks, who attempt an invasion of Earth after the Dalek Emperor recreates the race following the events of the Last Great Time War.

- After c. 1,000,000,000,000 AD: "Hell Bent" establishes that the Doctor's home planet, Gallifrey, has been hiding at the end of time. (Note: dialogue in the episode suggests this point is only around 4,500,000,000 AD, however this contradicts other episodes that place the end of time as happening much later.) Later in the episode, the Doctor and his companion, Clara Oswald, travel even further in time (see below).
- 100,000,000,000,000 AD: "Utopia": The last remnants of humanity (who have mostly evolved back into today's familiar form) seek out a legendary utopia in this year, aided by a Time Lord with suppressed memories, revealed to be the Master.

It is stated that Orson is on one of the last planets in the universe.
- In "Hell Bent", the Doctor and Clara travel to a point when Gallifrey is orbiting the last star in the universe and is inhabited only by the immortal known as "Me."

The Future is Wild
The Future is Wild was a speculative documentary hypothetising how life could evolve over the course of millions of years:
- 5,000,000: the world is in an ice age. The Mediterranean Sea will be a vast salt plain and the Amazon rainforest will be a grassland. Creatures of this land include huge killer birds, thin-legged pigs, sticky-frilled lizards and birds that act like whales. Humans, by this time, have either gone extinct or have left the planet.
- 100,000,000: in 100,000,000 years' time, the world will be very hot due to excess volcanic activity. Antarctica will be a lush rainforest. Creatures of this world include dinosaur-sized tortoises, amphibious octopuses, four-winged birds and eusocial spiders. At this time, there is also only one species of mammal left, which is "farmed" by the spiders.
- 200,000,000: in 200 million years' time the world will contain one global ocean and one continent, like Pangaea. Approximately 100 million years before this time, there was a mass extinction and now most of the world's land is desert, with few rainforests. Creatures of this world include air-breathing flying fish, giant plankton, various huge worms, highly specialized insects and intelligent, arboreal land-squid. There are no mammals, no birds, no reptiles, no amphibians, only one species of flowering plant and only sharks left to represent aquatic fish. Other creatures have moved in to fill these niches.

"The Last Question"
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.
- ca. 22,000: Humans, now immortal, are filling up the Milky Way galaxy and are considering expanding beyond it. The Galactic AC is asked the question and replies: "THERE IS INSUFFICIENT DATA FOR A MEANINGFUL ANSWER"
- ca. 10,000,000,000: Mankind now sleeps in hibernation as minds travel the universe. The hyperspatial computer the Universal AC is asked the question and replies, "THERE IS AS YET INSUFFICIENT DATA FOR A MEANINGFUL ANSWER."
- ca. 100,000,000,000: Man, now a single cosmic intelligence, realizes that the stars are winding down. The Cosmic AC is asked the question and responds: "THERE IS AS YET INSUFFICIENT DATA FOR A MEANINGFUL ANSWER."
- ca. 10,000,000,000,000: Man fuses with the AC and entropy destroys the universe. Some unspecified amount of time later, the AC, from its home in hyperspace, formulates its answer to the question and demonstrates it with the exclamation "Let there be light!"

- The disparity in the Xenogears years is due to the vagueness of the calendar conversions used in the game. The accompanying literature, Xenogears Perfect Works (PW), states that in AD 2510 the calendar system restarted and was labeled TC, for Transcend Christ. Again in year 4767 TC, the calendar system restarts and is called the New Era (the reference point being the year the Eldridge crashed onto the unnamed planet). PW continues on, stating the events of Xenogears begin in the year 9999 of the New Era. Whether year 0 is counted in any of the calendar systems is up for debate therefore leading to the disparity in the beginning of the events of the game.
