Inflationary universe: A possible solution to the horizon and flatness problems

- A. Guth
- Physics
- 15 January 1981

The standard model of hot big-bang cosmology requires initial conditions which are problematic in two ways: (1) The early universe is assumed to be highly homogeneous, in spite of the fact that… Expand

Fluctuations in the New Inflationary Universe

The spectrum of density perturbations is calculated in the new-inflationary-universe scenario. The main source is the quantum fluctuations of the Higgs field, which lead to fluctuations in the time… Expand

Could the Universe Have Recovered from a Slow First Order Phase Transition

- A. Guth, E. Weinberg
- Physics
- 14 February 1983

We investigate the cosmological consequences of a phase transition which is driven primarily by slow nucleation of bubbles of the new phase via the effectively zero temperature quantum tunneling… Expand

Inflationary spacetimes are not past-complete

- A. Borde, A. Guth, A. Vilenkin
- Physics
- 1 October 2001

Many inflating spacetimes are likely to violate the weak energy condition, a key assumption of singularity theorems. Here we offer a simple kinematical argument, requiring no energy condition, that a… Expand

Do dark matter axions form a condensate with long-range correlation?

- A. Guth, M. Hertzberg, C. Prescod-Weinstein
- Physics
- 18 December 2014

The authors investigate the formation of Bose-Einstein condensates from axion dark matter, and it is shown that a homogeneous condensate with long range correlations is unstable when… Expand

Is it possible to create a universe in the laboratory by quantum tunneling

Abstract We explore the possibility that a new universe can be created by producing a small bubble of false vacuum. The initial bubble is small enough to be produced without an initial singularity,… Expand

The Inflationary Universe: The Quest for a New Theory of Cosmic Origins.

- A. Guth, K. Jagannathan
- Physics
- 1997

* The Ultimate Free Lunch * The Cosmic Vista from Ithaca, New York * The Birth of Modern Cosmology * Echoes of a Scorching Past * Condensation of the Primordial Soup * Matters of Matter and… Expand

An obstacle to creating a universe in the laboratory

Abstract We show that any spherically symmetric false vacuum bubble which forms in an asymptotically flat space and grows beyond a certain critical size must have merged from an initial singularity.… Expand

Supernatural inflation: inflation from supersymmetry with no (very) small parameters

- L. Randall, M. Soljačić, A. Guth
- Physics
- 29 December 1995

Abstract Most models of inflation have small parameters, either to guarantee sufficient inflation or the correct magnitude of the density perturbations. In this paper we show that, in supersymmetric… Expand
