%0 Journal Article %T Quantum cosmology and eternal inflation %A Alexander Vilenkin %J Physics %D 2002 %I arXiv %X This contribution consists of two parts. In the first part, I review the tunneling approach to quantum cosmology and comment on the alternative approaches. In the second part, I discuss the relation between quantum cosmology and eternal inflation. In particular, I discuss whether or not we need quantum cosmology in the light of eternal inflation, and whether or not quantum cosmology makes any testable predictions. %U http://arxiv.org/abs/gr-qc/0204061v1
