Euclidean Wormholes, Baby Universes, and Their Impact on Particle Physics and Cosmology

The euclidean path integral remains, in spite of its familiar problems, an important approach to quantum gravity. One of its most striking and obscure features is the appearance of gravitational instantons or wormholes. These renormalize all terms in the Lagrangian and cause a number of puzzles or e...
