Timeline for 5,000,000,000
Far future

The year 5,000,000,000 was also known as 5.5/Apple/26. (TV: The End of the World, New Earth)

Earth Death[]

In the year 5,000,000,000, the sun expanded and the Earth was finally destroyed in what was designated Earth Death. The sun had been prevented from expanding by the National Trust who used satellites to hold the expanding star back. However, when their money ran out, nature was left to take its course. The Face of Boe sponsored an event for the richest people to observe the event on the "observation deck" on Platform One.

Earth's final moments. (TV: The End of the World)

During the event, Lady Cassandra gifted metal spiders through the Adherents of the Repeated Meme to infiltrate Platform One and profit from the compensation from a faked hostage crisis. The Ninth Doctor and Jabe thwarted this plan, so Cassandra fell on her back-up plan: to teleport away and deactivate the protective shielding on Platform One with her spiders, profiting from the shares of the doomed guests' rivals. The Doctor and Jabe rebooted the shields at the cost of Jabe's life, and Cassandra's teleport was reversed, causing her skin graft to break apart due to Cassandra's surgeons not being present to keep her moisturised. (TV: The End of the World) However, her brain survived. (TV: New Earth)

As the satellite was breaking apart, all of the guests were too busy saving themselves for anyone to witness the Earth's destruction. The planet was reduced to asteroids. (TV: The End of the World) At the same time as the sun swallowed the Earth, a group of Daleks from the Second Dalek War was tricked into flying into the sun, having been sent there from the Cathedral of Contemplation by the Tenth Doctor and the Fourth Doctor. (AUDIO: Out of Time)

According to the Tenth Doctor, "as soon as the Earth burn[ed] up", a revival movement arose among the human populations of the known galaxies, who became nostalgic for their lost home and they banded together with plans to recreate Earth to remember their old world. When they found a planet which was the same size, same gravity, with the same atmosphere and similar orbit around its star in Galaxy M87, they colonised it, naming it New Earth. (TV: New Earth)

Other events[]

In the course of this year, some of Agatha Christie's books were republished. A reprint of one, Death in the Clouds from 1935, was obtained by the Tenth Doctor and kept in a chest in his TARDIS. (TV: The Unicorn and the Wasp)

Around this time, the Chelonians controlled several breeding planets. One was destroyed by Natalie Sharrocks when she was possessed by an incorporeal entity. (PROSE: The Body Bank)

The Doctor encountered Montodon Slemm. (COMIC: Growing Terror)

The year 5,000,000,000 was among the possible years listed by the Tenth Doctor as he found the TARDIS accelerating into the far future until it finally settled on the year 100,000,000,000,000 at the end of the universe. (TV: Utopia)

Panda and the Jane Fonda incarnation of Iris Wildthyme visited an Earth-colony that looked "suspiciously like the M25" and witnessed the death of the giant head of Mr Derek. (PROSE: From Wildthyme with Love)
