Eternal inflation and the present universe
Alexander Vilenkin
Eternally inflating universes can contain thermalized regions with different values of the cosmological parameters. In particular, the spectra of density fluctuations should be dif…
Effective noise in stochastic description of inflation
S. Winitzki, A. Vilenkin
Stochastic description of inflationary spacetimes emulates the growth of vacuum fluctuations by an effective stochastic ``noise field'' which drives the dynamics of the volume-smoo…
Eternal inflation, black holes, and the future of civilizations
J. Garriga, V. F. Mukhanov, K. D. Olum +1
We discuss the large-scale structure of the universe in inflationary cosmology and the implications that it may have for the long-term future of civilizations. Although each civili…
On likely values of the cosmological constant
Jaume Garriga, Alexander Vilenkin
We discuss models in which the smallness of the effective vacuum energy density and the coincidence of the time of its dominance with the epoch of galaxy formation $t_G…
The cosmological constant and the time of its dominance
Jaume Garriga, Mario Livio, Alexander Vilenkin
We explore a model in which the cosmological constant and the density contrast at the time of recombination are random variables, whose range and {\it a priori} proba…
Macroscopic parity violating effects and 3He-A
G. E. Volovik, A. Vilenkin
We discuss parity violating effects in relativistic quantum theory and their analogues in effective field theory of superfluid 3He-A. A mixed axial-gravitational Chern-Simons term…
