Some light reading for you

Stephen Hawking has co-written a book entitled The Grand Design. In it he posits some relevant ideas – namely, as explained in Michael Shermer’s article, “that our brains form models of the world from sensory input, that we use the model most successful at explaining events and assume that the models match reality (even if they do not), and that when more than one model makes accurate predictions “we are free to use whichever model is most convenient.” Employing this method, Hawking and Mlodinow claim that “it is pointless to ask whether a model is real, only whether it agrees with observation.””

Heavy going, but if you’re interested, read more here.
