Query: A Farewell to Falsifiability   Some of the most obviously correct physical theories - namely string theory
and the multiverse - make no testable predictions, leading many to question
whether we should accept something as scientific even if it makes no testable
predictions and hence is not refutable. However, some far-thinking physicists
have proposed instead that we should give up on the notion of Falsifiability
itself. We endorse this suggestion but think it does not go nearly far enough.
We believe that we should also dispense with other outdated ideas, such as
Fidelity, Frugality, Factuality and other "F" words. And we quote a lot of
famous people to support this view.
