Eternally inflating multiverse and many worlds in quantum mechanics: Same concept?

Recent observational and theoretical progress has led to the dramatic new view that our universe may be one of the many universes in which low energy physical laws take different forms: the multiverse. I describe impacts this view may have on our fundamental understanding of spacetime and gravity, especially the idea that the eternally inflating multiverse and quantum mechanical many worlds are the same thing. I will also mention possible future observations that may further probe the multiverse
