Alan Guth's 2007 paper, "Eternal inflation and its implications", [3] states that under reasonable assumptions "Although inflation is generically eternal into the future, it is not eternal into the past." Guth detailed what was known about the subject at the time, and demonstrated that eternal inflation was still considered the likely outcome ...
In this toy multiverse, the left-hand region exits inflation (red line) later than the right-hand region. With the proper-time cutoff shown by the black dotted lines, the immediately post-inflation portion of the left-hand universe dominates the measure, flooding the measure with five "Boltzmann babies" (red) that are freakishly young.
In his 2012 journal, Lehners wrote about how pocket universes can emerge as a result of eternal inflation. 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 ...
Alternative models, where the average expansion of the universe throughout its history does not hold, have been proposed under the notions of emergent spacetime, eternal inflation, and cyclic models. Vilenkin and Audrey Mithani have argued that none of these models escape the implications of the theorem. [ 8 ]
The inflation itself may be the consequence of the Higgs field trapped in a false vacuum state [14] with Higgs self-coupling λ and its β λ function very close to zero at the planck scale. [ 15 ] : 218 A future electron-positron collider would be able to provide the precise measurements of the top quark needed for such calculations.
In eternal inflation, regions with inflation have an exponentially growing volume, while regions that are not inflating do not. This suggests that the volume of the inflating part of the Universe in the global picture is always unimaginably larger than the part that has stopped inflating, even though inflation eventually ends as seen by any ...
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 ...
Linde called this process eternal inflation. Quantum fluctuations produced during eternal chaotic inflation are so large that they can easily push different parts of the universe from one vacuum state to another, and even change the effective dimensionality of spacetime. This provided a very powerful realization of the theory of the multiverse.
