An oracle machine or o-machine is a turing a-machine that pauses its computation at state o while, to complete its calculation, it awaits the decision of the oracle—an unspecified entity apart from saying that it cannot be a machine (turing (1939), the undecidable, p 166–168.

Turing interpreted this to mean a computing machine and set out to design one capable of resolving all mathematical problems, but in the process he proved in his seminal paper ‘on computable numbers, with an application to the entscheidungsproblem [‘halting problem']’ (1936) that no such universal mathematical solver could ever exist.
