Yes, right, exactly, this is the kind of explanation that I've been saying is warranted spelling out. And there's a lot to discuss here - what does it even mean for a multitude of parallel universes to exist? why should we believe that's something that's possible? how does it work exactly? what are the implications of such a theory? is there any rigorous science we can do to flesh out how this works? and other questions. And people have written a lot on this topic.
