5000000000

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)

During their 2015 invasion of Earth, the Hyperions placed a fusion web around the sun to drain its energy. The Twelfth Doctor connected this web to his TARDIS, transporting it to the year 5000000000, where it was destroyed as the sun expanded. (COMIC: The Hyperion Empire)

Aftermath

Just before their run-in with Montodon Slemm his robotic gardener SNIP-7, the Tenth Doctor and Rose Tyler reunited with Coffa and Lute, who they had previously met on Platform One. Coffa and Lute told them that the survivors of Platform One had been disappearing. The Doctor and Rose then set off to check in with everyone who had survived. (COMIC: Growing Terror) While looking for Cal MacNannovich, they had an encounter with some Banjunx on the set of a Zemm Foolini hyperfilm. Foolini told them Cal was missing from the set. (COMIC: Hyperstar Rising) Next they went to the home world of the brothers Hop Pyleen, who were also missing. When Skip Pyleen stole a Hyposlip 500 Lightspeed-Podule developed by the brothers, and attempted to sell it to the Rakkonoids, the Doctor caught him in the act. (COMIC: Death Race Five Billion)

Hoping to catch up with the Chosen Scholars of Class 55, the Doctor and Rose visited the University of Rago Rago 56 Rago library. When Rose attempted to take a virtual tour using one of the library's mindlink devices she became infected by Macrobes, who had been hiding in the university's computer network waiting for an opportunity to infect living brains. The Doctor successfully forced the Macrobes to retreat into the computer network before disconnecting it, and left with Rose after realising the Chosen Scholars had also disappeared. (COMIC: The Macrobe Menace)

After downloading information about lectra energy from one of the university's mindlink data discs, the Doctor learned that lectra energy leaks resulted from power-boosted transmat beams. He had noticed this energy in all the places the guests of Platform One had disappeared from, and realised that tracing lectra energy leaks could lead them to whoever had been abducting the guests. The Doctor and Rose then visit Gameworld Gamma, where Mr and Mrs Pakoo are hunting human beings. Using his psychic paper, the Doctor poses as President Kaakaa and convinces the huntsmasters to ban the annual hunt. He then tries to return to the Pakoos, only to find they have been abducted too, leaving a trail of lectra energy behind. (COMIC: Reunion of Fear)

The Doctor and Rose traced the lectra energy back to the Elth of Balhoon, who had been kidnapping the Platform One survivors as revenge for them not saving his brother. When the Doctor freed the prisoners, Elth began to cry. Seeing his pain, the Platform One survivors all gathered round and offered their support. (COMIC: Reunion of Fear)

New Earth

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 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)

The Übermarket existed during this time. (COMIC: The Great Shopping Bill)
