From the basic definition of vacuum energy as being tied in with the Uncertainty principle, I would expect this not to include the Cosmic Background Radiation. Right? On the other hand, in figuring out
(a) the Casimir effect, one attributes the force to the field between the plates carrying less energy than the vacuum... but the CMB is always there as well, so one would imagine that this would contribute to the pressure on the plates
(b) why the observable universe is nearly spatially flat and how inflation smooths it down, it is not clear whether this takes the CMB into consideration or not.
Thanks for any attempts to clear up my confusion.
