From Wikipedia, the free encyclopedia

The 11th millennium and beyond is a period of time that will begin on 1 January 10001 CE. Several predictions have been made concerning this future time period. This article is a compendium of these predictions ranging from factual astronomical knowledge to the predictions of science fiction.

Astronomical events

This section lists several rare astronomical events expected to occur after the year 10000.^[1][2][3]

All dates are in a uniform time scale like Terrestrial Time. When converted to our ordinary solar time or Universal Time, which is decidedly non-uniform, via ΔT, the dates would be a few days earlier. Because of this difference, these dates have no anniversary relation to historical dates. Furthermore, they are only astronomical dates, so they are given in the astronomical format of Year Month Day.

Predicted events after year 1,000,000

• 1,000,000,000: The last total solar eclipse on Earth will occur, due to the Moon's orbit gradually becoming larger and spreading away from the earth (see Tidal acceleration for more on this).^[11]
• 3,000,000,000: The Andromeda Galaxy and our Milky Way Galaxy are predicted to collide.
• 5,400,000,000: The Sun leaves the main sequence, becoming a red giant.^[12]

• 100,000,000,000: The Virgo Supercluster merges into one super galaxy, millions of light-years across, filled with red dwarfs and small amounts of white dwarfs. Other superclusters have also merged, yet have been separated from each other by distances of more than a billion light-years due to the acceleration of dark energy.

Intelligent life existing then may flee to other universes, as suggested by the physicist Michio Kaku. Beginning of the Degenerate Era of our universe. End of normal star formation and normal stars in the Milky Way/M31 super-galaxy. New stars formed only via brown dwarf collisions every hundred billion years or so.

Tipler's Omega Point Theory,^[16] but due to a supertask of computation before the final singularity, its simulated inhabitants experience an infinite subjective lifetime.
• 10,000,000,000,000,000,000 (10 quintillion): The Galaxy relaxes gravitationally. Ninety percent of stars escape into intergalactic space while the rest merge with the central Black Hole.
• 10⁴⁰: Beginning of the Black Hole Era of our universe, unless proton decay does not occur.
• 10¹⁰⁰ (one googol): If the theory of black hole evaporation is correct, it is predicted by many astronomers that all the black holes in our universe will have evaporated by around this year, the beginning of the Dark Era of our universe, unless proton decay does not occur.
• 10¹⁵⁰⁰: Cold fusion occurring via quantum tunneling should make the light nuclei in ordinary matter fuse into iron-56 nuclei (see isotopes of iron.) Fission and alpha-particle emission should make heavy nuclei also decay to iron, leaving stellar-mass objects as cold spheres of iron.
• to : Stellar mass objects collapse into black holes by quantum tunneling.
• : Quantum tunneling may make iron stars collapse into neutron stars.

Eras
