Inflationary universe: A possible solution to the horizon and flatness problems
- A. Guth
- 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…

Could the Universe Have Recovered from a Slow First Order Phase Transition
Is it possible to create a universe in the laboratory by quantum tunneling
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…
An obstacle to creating a universe in the laboratory
Do dark matter axions form a condensate with long-range correlation?
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 interactions like gravity are taken into account.
Inflationary spacetimes are not past-complete
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…
