Obviously, the intended meaning of Emergy, was emergENCy but the letters ENC were missing. But there is more. As an autist I immediately saw that Emergy looked like the word ENERGY with an M swapped in for an N. And look at ENC! If I do the swap with that N, then I get the word ENERGY and the left over characters are EMC which is pretty obviously, the fundamental equation for energy in the universe.
E = mc²
