| Causal Structure of an Inflating Magnetic Monopole (1999) | |||||||||
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.. Comment: 6 pages (text), revtex, 5 ps figures separate, to appear in Phys Rev D, Fig 3 and discussions are modified | |||||||||
