But Sean Carroll says there are multiple Sean Carrolls that come into being as the MWI branches, so whatever charge Sean Carroll now has is "replicated" in World x and World y, and then the multiple Sean Carrolls go do their own things independently. That's exactly what he says happens. @philipthrift -- You received this message because you are subscribed to the Google Groups "Everything List" group.
