    The mechanism was an example of ... resulted in an enormous and exponential expansion ... these included the Lambda-CDM model and a mixed cold/hot dark matter model.

  3. Cosmic inflation - Wikipedia

    en.wikipedia.org/wiki/Cosmic_inflation

    Paul Steinhardt, one of the original architects of the inflationary model, introduced the first example of eternal inflation in 1983. [97] He showed that the inflation could proceed forever by producing bubbles of non-inflating space filled with hot matter and radiation surrounded by empty space that continues to inflate.

  4. Lambda-CDM model - Wikipedia

    en.wikipedia.org/wiki/Lambda-CDM_model

    The model includes a single originating event, the "Big Bang", which was not an explosion but the abrupt appearance of expanding spacetime containing radiation at temperatures of around 10 15 K. This was immediately (within 10 −29 seconds) followed by an exponential expansion of space by a scale multiplier of 10 27 or more, known as cosmic ...

  5. Inflaton - Wikipedia

    en.wikipedia.org/wiki/Inflaton

    The inflaton field is a hypothetical scalar field which is conjectured to have driven cosmic inflation in the very early universe. [1] [2] [3] The field, originally postulated by Alan Guth, [1] provides a mechanism by which a period of rapid expansion from 10 −35 to 10 −34 seconds after the initial expansion can be generated, forming a universe not inconsistent with observed spatial ...

  6. Inflationary epoch - Wikipedia

    en.wikipedia.org/wiki/Inflationary_epoch

    Most inflationary models propose a scalar field called the inflaton field, with properties necessary for having (at least) two vacuum states. It is not known exactly when the inflationary epoch ended, but it is thought to have been between 10-33 and 10-32 seconds after the Big Bang. The rapid expansion of space meant that any potential ...

  8. Accelerating expansion of the universe - Wikipedia

    en.wikipedia.org/wiki/Accelerating_expansion_of...

    According to the theory of cosmic inflation, the very early universe underwent a period of very rapid, quasi-exponential expansion.While the time-scale for this period of expansion was far shorter than that of the existing expansion, this was a period of accelerated expansion with some similarities to the current epoch.

  9. De Sitter universe - Wikipedia

    en.wikipedia.org/wiki/De_Sitter_universe

    A de Sitter universe is a cosmological solution to the Einstein field equations of general relativity, named after Willem de Sitter.It models the universe as spatially flat and neglects ordinary matter, so the dynamics of the universe are dominated by the cosmological constant, thought to correspond to dark energy in our universe or the inflaton field in the early universe.
