Primordial inflation provides a sensible microphysical explanation for the properties of our observable universe on large scales. Also, the present universe seems to have entered a stage of low energy inflation. In theories with several vacua, transitions between inflating vacua and neighboring ones lead to the picture of an eternally inflating multiverse, where regions with different properties of the low energy physics can be found sitting next to each other. I will review the status of the mathematical description of the multiverse, some outstanding questions it raises, and some avenues for a resolution of these questions.
