The source and mechanism of the astrophysical jets, such as from blazars and quasars, is still to be completely unravelled. In this article, a theory is explored using general relativity and a thought experiment for primarily black hole (BH) derived jets as a model for how electrons could escape the BH in various forms such as a central jet spine. Thresholds for emission are suggested, how it could affect the escape velocity of the jets, its composition and a way for the process to give the BH locally or wholly a charge. We attempt to combine quantum mechanics and general relativity through the photoelectric effect and how gravitational acceleration from the mass of the BH causes blue shifting or gain in frequency of quantum fluctuations and resulting high energy photons for an isolated BH, contributing to the loss of BH mass, corresponding to changes in the equations of general relativity for different BHs and Stephen Hawkings predictions. From our calculations we reach the fine structure constant 1/137 and suggest that it represents an extremal Planck BH. The spin, charge, intensity by surface area and surface gravity are interlinked, also affected by the mass, resulting in the output radiation seen. We suggest a way to interpret BH radiation, primarily using input frequency corresponding to resulting output kinetic energy and conversion to radiation at the event horizon after BH photoelectric effect interaction at an area around the Cauchy Horizon to which particles, through quantum fluctuations, may tunnel from the singularity, essentially separating from the BH, another parameter being the change in mass. Theoretically, localised BH extremal intrinsical areas may commonly form in nature at astronomical scales rather than fully at once, jets as one example, whereas at Planck scale or below, fully may be a common feature and perhaps be part of quantum fluctuations itself. Furthermore, the theory suggests that the outward force generated by gravity through the photoelectric effect, paradoxically, may continuously prevent further collapse of BH.
