The Inflationary Universe is a popular physics book by theoretical physicist Alan H. Guth, first published in 1997.The book explores the historical and theoretical development and expansion of the theory of inflation, which was first presented by the author in 1979 as the culmination of his research on the implications of theory of the Big Bang.
When inflation ends, the temperature returns to the pre-inflationary temperature; this is called reheating or thermalization because the large potential energy of the inflaton field decays into particles and fills the Universe with Standard Model particles, including electromagnetic radiation, starting the radiation dominated phase of the Universe.

Vacuum state is a configuration of quantum fields representing a local minimum (but not necessarily a global minimum) of energy. Inflationary models propose that at approximately 10 −36 seconds after the Big Bang, vacuum state of the Universe was different from the one seen at the present time: the inflationary vacuum had a much higher energy density.
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 ...
The story makes reference to the then-recent proposal that the universe is expanding, based on the discovery that distant astronomic bodies appeared to be receding.. The idea of a fractal universe, with atoms or subatomic particles of one scale corresponding to the stars of another scale, had been employed in other science fiction works, such as "Out of the Sub-Universe" (1928) by Roman ...
The mechanisms of inflation within these pocket universes could function in a variety of manners, such as slow-roll inflation, undergoing cycles of cosmological evolution, or resembling of the Galilean genesis or other 'emergent' universe scenarios. Lehners goes on to discuss which one of these types of universes we live in, and how that is ...
First appearance: 1971 short story collection All the Myriad Ways. The short story won the 1972 Hugo Award for best short story. Stan, the narrator, notices that the Moon is glowing much brighter than ever before. The people he meets as the story begins all praise the Moon's increased beauty but lack the scientific background to understand its ...
