I didn't try to do that. And I am not asserting the total energy of the

There is no global meaning to energy conservation. There is the Hamiltonian
constraint Nℌ = 0, which just says that for a local region where the lapse
function can be parallel translated to the energy is zero. This is for
Petrov type O solutions
Nℌ = 0 = ½(da/dt)^2 - 4πGρa^2/3c^3 - k
Which le

Alan Gray by your thought that "When an expanding gas cools, doesn't the
energy go into work done to cause the expansion". Let us assume that the
energy loss of red shift fuels the expansion of our universe. We know that
E=hc/(lamda) and derivative of energy w.r.t wavelength
If you attempt to Sum up all of the components, how close to 0 do you get?

But in a real operational sense, that is not the case.
There is nothing in theoretical physics that i

Silly question. If it is not conserved, it does't have to go anywhere -- it
just vanishes.
