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

So, the value of c₀ = 1/√(ε₀μ₀) applies only locally.

Please provide references for this assertion.

c, out there, can be higher or lower than the fixed 299,792,458 m/s that
arrogant assholes here want to project and use for the entire infinite
universe.

Even the Alan Guth's Big Bang model consider this as a fact in the

after the inflation. The speed of light is considered, in the BBT, as
almost infinite at the beginning of light, when it appeared after the
BB.

Now, who can be so imbecile to believe that c₀ = 299,792,458 m/s apply
for the entire universe of now, 3,000,000,000 ly far from here?

The question as to whether accepted physical "constants" are indeed
constant over all space and all time is an important one. Various
theories suggest that they may not be.
Experiments and careful measurements, both astronomical and in
terrestrial laboratories, have been conducted to test whether such
variations in fact exist. Here are some references on searches for
variation in the fine structure constant, the gravitational constant
and so forth. It's easy to find LOTS more. To date, all measured
variations have been consistent with zero.

Only retarded scientists in the last 100 years, so they can keep
pretending that they can MODEL the entire universe and its behavior,
living in a remote dust calling Earth.
