The formula proposed, as I told you, is energy equals the mass times the speed of light squared, and light is very fast indeed. So that with only a little matter, if any of its energy were released into the world...' She shook her head. 'Of course the strong force means that would never happen. But we continue to investigate this element alactin, that the Travancori physicists call Hand of Tara. I suspect its heartknot is unstable, and Piali is beginning to agree with me. Clearly it is very full of the jinni, both yin and yang, in such a fashion that to me it is acting like a droplet of water held together by surface tension, but so big that the surface tension is just barely holding it, and it stretches out like a water drop in the air, deforming this way and that, but held together, just, except for sometimes, when it stretches too far for surface tension, the strong force in this case, and then the natural repulsion between the jinni makes a heartknot split in two, becoming atoms of lead, but releasing some of its bound power as well, in the form of rays of invisible energy. That's what we are seeing on the photographic plates you help with. It's quite a bit of energy, and that's just one heartknot breaking. What we have been wondering what we have been forced to consider, given the nature of the phenomenon - is, if we gathered enough of these atoms together, and broke even one heartknot apart, would the released qi break a lot more of them at the same time, more and more again all at the speed of light, in a space this big,' holding her hands apart. 'If that might not set off a short chain reaction,' she said.
