The Anti-Scientific Argument for the Multiverse
The work of a theoretical physicist will depend on whether or not there are regions far away where the cosmological constant takes on different values. You can't just say, well, I can't see those other universes, therefore I would ignore them. We play an explanatory role in what we actually do observe and this is not like tricky or subtle. So I don't think I don't buy the argument that the multiverse is intrinsically anti-scientific. In any way, I think that's just wrongheaded and bad philosophy.
