The discussion explores the limitations of the electromagnetic spectrum, suggesting that the lowest frequency is tied to blackbody radiation at absolute zero, while the upper limit may be defined by Planck energy. It raises the question of whether electromagnetic energy can be weaponized against civilians, comparing potential methods to existing military systems like ADT or ADS. A personal account mentions experiencing an attack in Long Beach, California, described as a shockwave with electricity. The conversation highlights concerns about the application of electromagnetic energy as a weapon. Overall, the topic underscores the intersection of physics and potential civilian safety issues.
