I don’t see why it’s unbelievable. High mass energy conversion is one of the least crazy things about black holes imo. For readers who want some quick info: https://youtu.be/t-O-Qdh7VvQ https://youtu.be/t-O-Qdh7VvQ This PBS SpaceTime video doesn’t talk about the practical uses of Kugelblitzes, but it isn’t a big leap from understanding what they are to how to get energy out of them. Hawking radiation rate increases as schwarzschild radius decreases. If you could make a properly sized black hole you could convert a little bit of mass into a lot of energy. Maybe this could be harnessed to solve all electricity demand issues. Maybe it could be used to make a room sized bomb that blows up Earth.

I didn't say it was unbelievable, it's just ... very interesting, compared to all of the other space opera business. It implies that passing through this empty surface, this topological construct which itself need not have particles nearby (depending on how close you feel the singularity is to "nearby") makes this (and other typically conserved numbers) no longer all that important ... but only from the vantage point of an outside observer. In other words, relativity is intertwined with this conservation, as it is observer dependent.

  I agree. It’s definitely very cool. It really highlights the mass energy equivalence. I’m not at a level of full intuition of relativity, but it’s one of those things that made a lot more sense once I understood mass energy equivalence. Like where the energy in exothermic fusion comes from: When the strong nuclear force overcomes the electrostatic force, the strong nuclear force increases the kinetic energy (momentum/speed) of the particles. At this point the mass of all particles from their own frames of reference is the same. Once the kinetic energy is lowered (particles are slowed back down to the same speed/temperature of their surroundings) does the mass lower.
