Re: E = 3/4 mc? or E = mc?? The forgotten Hassenohrl 1905 work.

Permittivity and permeability at the center of each galaxy are different

So, the value of c? = 1/√(????) applies only locally.

There we go again.
Is there really no part of physics that you don't misunderstand?
FYI, eps_0 and mu_0 are not physical quantities.
They are artifacts of an ill-conceived unit system. (the SI)

In any half-way decent unit system they are both equal to 1,
with c appearing explictly in Maxwell's equations in the right places.

Even saying that they have been put equal to one is too kind to them.
They just have no physical existence at all,

They are as physical as the 'tractability of free space' tau_0.
You know, the dimensionless constant with value one
that appears in Newton's force law:

F = tau_0 m a
