60000000000

60,000,000,000, or 60 billion, was a year around which the Grandfather's Maw swallowed the Hydra-Centaurus Cluster and destroyed the Magellanic Clouds and the Andromeda and Milky Way galaxies. At least one Homeworld was predicted to be destroyed around this time. (PROSE: The Brakespeare Voyage)
Some speculated this year to be the end of the universe itself (AUDIO: Zagreus) — though the universe was known to have survived for a much longer time. By the year 100000000000000, the universe was still in existence, though it was closer to death than not. (TV: Utopia)
