Measures of the multiverse
Speaker(s): Alexander Vilenkin
Abstract: Inflation is generically a never ending process, with new 'pocket universes' constantly being formed. All possible events will happen an infinite number of times in such an eternally inflating universe. Unless we learn how to compare these infinities, we will not be able to make any predictions at all. I will discuss some proposed approaches to this 'measure problem'.
