A perspective on the landscape problem
arXiv:1202.3373 · doi:10.1007/s10701-012-9652-x
Abstract
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.
