More directly, Lee Smolin has come up with an idea where inside black holes you pinch off a new universe with slightly different constants of nature. Now that's much less well-defined because in the string theory case you have microscopic dynamics that predict the existence of a multiverse. Those dynamics might not be right, but at least the theory is there. Smolin is just hypothesizing.
