Another positive discussion of the need for falsifiability:-http://www.salvomag.com/new/articles/salvo33/proving-grounded.php-"But today, some scientists want to throw falsifiability overboard. They hope by doing this to protect the concept of the multiverse. Put simply, there is currently no evidence for the existence of any universes other than our own, making the theory of the multiverse unfalsifiable. But if the proposal to dispense with falsifiability were accepted, that would be very convenient for naturalist atheists. They could then argue that any stream of events that occurs in our universe may well have occurred differently in any one of an infinite number of other universes. So no inferences (other than their own) could be drawn from a given state of affairs here in the only world for which we have information. -****-"Faced with difficulties in applying fundamental theories to the observed Universe, some researchers called for a change in how theoretical physics is done. They began to argue—explicitly—that if a theory is sufficiently elegant and explanatory, it need not be tested experimentally, breaking with centuries of philosophical tradition of defining scientific knowledge as empirical. We disagree. As the philosopher of science Karl Popper argued: a theory must be falsifiable to be scientific. "
