My son in law has a PHD in atmospheric chemistry and teaches physics at a northwestern university: Here is his take on it: Hi Chuck - Yes, your friend is correct. The existence of gravity waves do not necessarily mean that the multiverse hypothesis is correct. However the logic goes something like this: As you know, the inflation epoch resulted in rapid inflation of the universe (doubled its size many times over in ~ 10^-34 seconds). It has continued to expand since that period. But the initial inflation - which was faster than the speed of light - left its mark through gravity waves which are the result of quantum fluctuations. Imagine a bell ringing and the sound spreading out in time and space. The quantum fluctuations are observed, therefore, at small and large scale - linking gravity and quantum mechanics (what Einstein was looking for - wow). There have been many different models of inflation proposed. One of the most favored at this point a chaotic inflation proposed by theorist Andrei Linde - who has been in the news a lot in the last couple days - is evidently supported by the most recent observational evidence in the cosmic microwave background polarization. It - like most (all?) eternal inflation models - have the universe expanding in some region at all times. Additionally, it predicts that this occurrence - inflation - is a common occurrence and therefore would create a large number of universes. There are any number of interpretations of the multiverse hypothesis, of course, so you can pick your flavor. I add the caveat here that this is way outside my field of expertise - so I report only as an outside observer to this work... just like you... son in law
