Proponents
Andrei Linde, Alexander Vilenkin
Evidence For
A natural mathematical consequence of many inflation models once taken to their logical extent.
Evidence Against
No observable evidence of other bubble universes is possible even in principle by definition, raising the question of falsifiability.
