I say theory, he says theory but what do you think we mean when we talk about theories, like Big Bang theory, the theory of evolution by natural selection, the theory of relativity (both general and special) and quantum theory. Well, we don’t mean it’s “just” a theory, like some vague idea a bloke down the pub came up with to explain the woes of the world, it’s not some conspiracy theory. If only we could’ve been more positive and used another word without the negative connotations of the man on the Clapham omnibus’ conception of the word theory…well, that’s the theory anyway.
