Causal Structure of an Inflating Magnetic Monopole

Abstract

We clarify the causal structure of an inflating magnetic monopole. The spacetime diagram shows explicitly that this model is free from ``graceful exit'' problem, while the monopole itself undergoes ``eternal inflation''. We also discuss general nature of inflationary spacetimes.
