In eternal inflation, the idea is that quantum fluctuations can drive the inflaton field "uphill" prolonging inflation in some areas. These would be your "bubble regions". Inflation stops in a region when it thermalizes. So you get domains of inflation continuing and domains where it stops. The problem is that eternal inflation itself is not a well-defined mechanism, and has many issues, see for example: arxiv.org/abs/arXiv:1408.2249 and arxiv.org/abs/1508.02670 (excuse the shameless self-promotion!) | |
