Local Observation in Eternal inflation
  We consider landscape models that admit several regions where the conditions
for eternal inflation hold. It is shown that one can use the no-boundary wave
function to calculate small departures from homogeneity within our past light
cone despite the possibility of much larger fluctuations on super horizon
scales. The dominant contribution comes from the history exiting eternal
inflation at the lowest value of the potential. In a class of landscape models
this predicts a tensor to scalar ratio of about 10%. In this way the
no-boundary wave function defines a measure for the prediction of local
cosmological observations.
