One way would be to make a "Kugelblitz". It works by concentrating a huge amount of energy in a very small space. Because of E=mc2, concentrating energy does the same thing as concentrating mass, and could create a black hole from which even the photons that created it can't escape, at least in theory. In practice, probably impossible, or at least well beyond our current technological capabilities. |
