comment Redshift of supernova light curve
So is it true to say that cosmological redshift is completely equivalent to time dilation? Could one consistently assert that an atomic clock ticking millions of years ago is actually slower than the equivalent clock today?

comment Redshift of supernova light curve
I'm just using a Gaussian as an example to understand how the width of a light pulse changes due to redshift.

comment Are electrons held together by vacuum energy?
To Jan Lalinsky: I would say that the discrepancy between the static field mass/energy and the moving field mass/energy still needs to be accounted for. I accept your point that one should not include the inertia in the em field if one's equation of motion only deals with forces that act on the body itself.

Using the vacuum equation of state $p=-\rho c^2$ one can derive the energy discrepancy $E_p$ correctly whereas when a careful calculation is done of the Casimir forces due to the vacuum inside the sphere one finds instead that they tend to expand the sphere instead of holding it together.

The vacuum equation of state $p=-\rho c^2$ can be justified on the grounds that it is Lorentz invariant so one does not require gravitational considerations.
