Is Feasibility in Physics Limited by Fantasy Alone

Although various limits on the predicability of physical phenomena as well as on physical knowables are commonly established and accepted, we challenge their ultimate validity. More precisely, we claim that fundamental limits arise only from our limited imagination and fantasy. To illustrate this thesis we give evidence that the well-known Turing incomputability barrier can be trespassed via quantum indeterminacy. From this algorithmic viewpoint, the “fine tuning” of physical phenomena amounts to a “(re)programming” of the universe. Take a few moments for some anecdotal recollections. Nuclear science has made true the ancient alchemic dream of producing gold from other elements such as mercury through nuclear reactions. A century ago, similar claims would have disqualified anybody presenting them as quack. Medical chemistry discovered antibiotics which cure Bubonic plague, tuberculosis, syphilis, bacterial pneumonia, as well as a wide range of bacterial infectious diseases which were considered untreatable only one hundred years ago. For contemporaries it is hard to imagine the kind of isolation, scarcity in international communication, entertainment and transportation most of our ancestors had to cope with.
