The problem comes from classical physics versus GR/QM.

Try the generalized FAQ on the problem

We have been thru this but energy in classical physics is poorly defined and not even consistent. In trying to drag your answers back to classical physics the answer becomes yes/no/maybe/never/I cant work it out ... choose which one applies.

Above in your quote you change from graviton energy in QM (very well defined definition of energy) to an ambiguous definition in classical physics or possibly GR it isn't clear to me which you want.

The problem is in classical physics the answer is whatever you want ... pick your own answer !!!!.

At the level you are working classical physics breaks down and there is no patch you can make for it.

Sort of along this line look at the one-minute physics video

I believe in "Evil, Bad, Ungodly fantasy science and maths", so I am undoubtedly wrong to you.
