A perspective on the landscape problem

Lee Smolin

(Submitted on 15 Feb 2012)

I discuss the historical roots of the landscape problem and propose criteria for its successful resolution. This provides a perspective to evaluate the possibility to solve it in several of the speculative cosmological scenarios under study including eternal inflation, cosmological natural selection and cyclic cosmologies.

Invited contribution for a special issue ofFoundations of Physicstitled:Forty Years Of String Theory: Reflecting On the Foundations. 31 pages

The 40 Years of String issue ofFoundations of Physicsis being assembled and edited by Gerard 't Hooft and friends. It should be an interesting, possibly influential, collection of articles.
