  2. Eternal return - Wikipedia

    en.wikipedia.org/wiki/Eternal_return

    Eternal return (or eternal recurrence) is a philosophical concept which states that time repeats itself in an infinite loop, and that exactly the same events will continue to occur in exactly the same way, over and over again, for eternity.

  3. Big Crunch - Wikipedia

    en.wikipedia.org/wiki/Big_Crunch

    The Big Crunch is a hypothetical scenario for the ultimate fate of the universe, in which the expansion of the universe eventually reverses and the universe recollapses, ultimately causing the cosmic scale factor to reach absolute zero, an event potentially followed by a reformation of the universe starting with another Big Bang.

  4. Ultimate fate of the universe - Wikipedia

    However, only a portion of the universe would be destroyed by the Big Slurp while most of the universe would still be unaffected because galaxies located further than 4,200 megaparsecs (13 billion light-years) away from each other are moving away from each other faster than the speed of light while the Big Slurp itself cannot expand faster than ...

  5. Cyclic model - Wikipedia

    en.wikipedia.org/wiki/Cyclic_model

    A cyclic model (or oscillating model) is any of several cosmological models in which the universe follows infinite, or indefinite, self-sustaining cycles. For example, the oscillating universe theory briefly considered by Albert Einstein in 1930 theorized a universe following an eternal series of oscillations, each beginning with a Big Bang and ending with a Big Crunch; in the interim, the ...

  6. Big Rip - Wikipedia

    en.wikipedia.org/wiki/Big_Rip

    In physical cosmology, the Big Rip is a hypothetical cosmological model concerning the ultimate fate of the universe, in which the matter of the universe, from stars and galaxies to atoms and subatomic particles, and even spacetime itself, is progressively torn apart by the expansion of the universe at a certain time in the future, until distances between particles will infinitely increase.

  7. Chronology of the universe - Wikipedia

    This time happens to correspond roughly to the time of the formation of the Solar System and the evolutionary history of life. Stelliferous Era: 150 Ma ~ 100 Ta [19] 20 ~ −0.99: 60 K ~ 0.03 K: The time between the first formation of Population III stars until the cessation of star formation, leaving all stars in the form of degenerate ...

  8. Expansion of the universe - Wikipedia

    en.wikipedia.org/wiki/Expansion_of_the_universe

    The history of the universe after inflation but before a time of about 1 second is largely unknown. [25] However, the universe is known to have been dominated by ultrarelativistic Standard Model particles, conventionally called radiation , by the time of neutrino decoupling at about 1 second. [ 26 ]

  9. Cosmic Calendar - Wikipedia

    en.wikipedia.org/wiki/Cosmic_Calendar

    A graphical view of the Cosmic Calendar, featuring the months of the year, days of December, the final minute, and the final second. The Cosmic Calendar is a method to visualize the chronology of the universe, scaling its currently understood age of 13.8 billion years to a single year in order to help intuit it for pedagogical purposes in science education or popular science.
