So, this is where Noether's theorem on conversation becomes
   unhelpful, yes?
   [1]https://en.wikipedia.org/wiki/Noether%27s_theorem... I read:
   [2]http://motls.blogspot.com/.../why-and-how-energy-is-not...
   which led me to Neother's theorem and that we seem to have:
   [3]https://en.wikipedia.org/.../Ward%E2%80%93Takahashi_identity
   as an equivalent and yet, only applies in cases where Special
   Relativity holes, but not with General Relativity. I also
   haven't had my coffee yet... I woke up very very late and I
   might be reading this all backwards, upside down, inside out,
   scrambled and fried.
