Journal ArticleDOI
Inflationary universe: A possible solution to the horizon and flatness problems
TL;DR: In this paper, the authors proposed a model of hot big-bang cosmology where the early universe is assumed to be highly homogeneous, in spite of the fact that separated regions were causally disconnected (horizon problem).
Journal ArticleDOI
Fluctuations in the New Inflationary Universe
Alan H. Guth,So-Young Pi +1 more
TL;DR: The spectrum of density perturbations in the new-inflationary-universe scenario is calculated in this article, where the main source is the quantum fluctuations of the Higgs field, which lead to fluctuations in the time at which the false vacuum energy is released.
Journal ArticleDOI
Inflationary spacetimes are incomplete in past directions.
TL;DR: A simple kinematical argument is offered that a cosmological model which is inflating--or just expanding sufficiently fast--must be incomplete in null and timelike past directions, and a bound on the integral of the Hubble parameter over a past-directed timelikes or null geodesic is obtained.
Journal ArticleDOI
Could the Universe Have Recovered from a Slow First Order Phase Transition
Alan H. Guth,Erick J. Weinberg +1 more
TL;DR: In this article, the cosmological consequences of a phase transition driven primarily by slow nucleation of bubbles of the new phase via the effectively zero temperature quantum tunneling process of Coleman and Callan are investigated.
