Living with Infinities
Steven Weinberg
This is the written version of a talk given in memory of Gunnar Källén, at the Departments of Theoretical Physics, Physics, and Astronomy of Lund University on February 13, 2009. I…
Non-Gaussian Correlations Outside the Horizon
Steven Weinberg
It is shown that under essentially all conditions, the non-linear classical equations governing gravitation and matter in cosmology have a solution in which far outside the horizon…
Effective Field Theory for Inflation
Steven Weinberg
The methods of effective field theory are used to study generic theories of inflation with a single inflaton field. For scalar modes, the leading corrections to the corr…
A Tree Theorem for Inflation
Steven Weinberg
It is shown that the generating function for tree graphs in the "in-in" formalism may be calculated by solving the classical equations of motion subject to certain constraints. Thi…
Quantum Contributions to Cosmological Correlations II: Can These Corrections Become Large?
Steven Weinberg
This is a sequel to a previous detailed study of quantum corrections to cosmological correlations. It was found there that except in special cases these corrections depend on the w…
Living in the Multiverse
Steven Weinberg
This is the written version of the opening talk at the symposium "Expectations of a Final Theory," at Trinity College, Cambridge, on September 2, 2005. It is to be published in Uni…
