This seems metaphysical to me.

comment Have red shifted photons lost energy and where did it go?
@bobie Asymptotic is asymptotic, regardless of the size. I never didn't accept that energy can be drained out. It can. However, again, the photon started with a net negative "potential energy", so everything evens out.

comment Have red shifted photons lost energy and where did it go?
@bobie It can't be completely drained out until it reaches infinity (or if it is beyond an event horizon). General relativity doesn't have a nice concept of "potential energy", however remember that a gravitational well has negative PE, so throwing an energetic photon up (and having it redshift into oblivion) conserves energy.

comment Green's function for a dielectric with a charge
It needs to ask about a specific concept, too. Showing work is secondary (see the linked policy for mode details)

Note: Chemistry is fine with this question, but so is Physics IMO.
