                         aspects of mathematics, theoretical physics, and as- trophysics 
                         related to black holes, as well as two other so-called 
                         {"}exotic{"} spacetimes: wormholes and spherically symmetric warp 
                         drives. The black holes of Schwarzschild, Reissner-Nordstr{\~o}m, 
                         Kerr, and Kerr-Newman then form solutions of vacuum and 
                         electro-vacuum of Einstein's field equations; respectively, they 
                         are black holes, neu- tral ones, with electric charge, with 
                         rotation, and with both rotation and electric charge. The analysis 
                         of light trajectories around black holes was conducted in order to 
                         study the behavior of massless particles in these curved spaces. 
                         Subsequently, this analysis was applied to the study of wormhole 
                         {"}shadows,{"} discussing the ef- fects of electric charge on the 
                         shape of the so-called photosphere. Additionally, the 
                         Blandford-Znajek mechanism was studied; In particular, the project 
                         investigated the shadows of charged wormholes, which constituted a 
                         novel result within the field of relativistic physics.",
