An attempt is made to solve the problem of observer dependency in the flat space-time situation. The standard results for the uniformly accelerated frame (UAF) are analyzed and the analysis is extended to nonuniformly accelerated frames, with the surprising conclusion that no ambiguity arises in the particle definition. Thus, physically realizable detectors do respond properly to the Minkowski definition of particles. It is shown, by explicit construction, that the results obtained using Green's functions need not agree with the results obtained through direct quantization of the field. Finally, the detection process is analyzed in detail and it is shown that the uncertainty principle rules out the possibility of detecting such a radiation. It is concluded that the UAF result is not physically relevant and represents an unobservable quantum fluctuation pattern.
