Abstract: We develop an analytic model that extends classical white hole geometry by incorporating both radiative dynamics and electric charge. Starting from a maximal analytic extension of the Schwarzschild white hole via Kruskal Szekeres coordinates, we introduce a time dependent mass function, representative of outgoing null dust to model evaporation. Building on this foundation, the study then integrates the Reissner-Nordstr”om framework to obtain a dynamic, charged white hole solution in double null coordinates. In the resulting Vaidya Reissner Nordstr”om metric, both the Bondi mass and the associated charge decrease monotonically with retarded time, capturing the interplay of radiation and electromagnetic effects. Detailed analysis of horizon behavior reveals how mass loss and charge shedding modify the causal structure, ensuring that energy conditions are preserved and cosmic censorship is maintained.
Analyzing the Conclusions of the Text
The text introduces an analytic model that extends classical white hole geometry by incorporating radiative dynamics and electric charge. The model starts with a maximal analytic extension of the Schwarzschild white hole using Kruskal-Szekeres coordinates. It then introduces a time-dependent mass function to model evaporation. By integrating the Reissner-Nordstr”om framework, a dynamic, charged white hole solution in double null coordinates is obtained. The resulting Vaidya Reissner-Nordstr”om metric shows that both the Bondi mass and the associated charge decrease with retarded time, capturing the interplay of radiation and electromagnetic effects. Additionally, the analysis of the horizon behavior shows how mass loss and charge shedding modify the causal structure while preserving energy conditions and maintaining cosmic censorship.
