Tom,

I was really careful in wording this part, still it has created confusion.
:)

Our point of observation is earth (or say  the solar system) and the 21st
Century is the time (which is a also a function of the expanding volume of
the universe). And the our devices of observation are made of earthly
matter of electron, proton and neutron.

So from this point of observatiom at this time if we observe using the
instruments of earthly matter, I believe that we have reasonable evidence
that speed of light is constant, and it has to be that value and no other
value. And speed of light should be related to how the universe is evolving
under these constraints.

For observers beyond the aforesaid space, it can neither be proved or
disproved , whether the speed is same. If large scale configuration of
space ( i.e. distribution of mater and additional volume created) changes,
which correspond to time change considerably,  there are reasons to doubt
whether speed of light will still remain constant even on earth.
Furthermore, it is simply an overconfidence if we declare that instrument
made from aforesaid earthly matter, can survive in other galaxies. But our
scientific knowledge has not progressed enough to address these extended
questions, so these are not so immediate concern.

The question of immediate concern is that why should the earthly matter,
located at earth in 21st century observe the speed of light as constant.
Einstein told us the reason that time dilates and length contracts as we
speed up. I may personally not believe in his explanation and I am sure
that there are many other who also do not believe. Nevertheless, not
believing is not enough, unless  better explanations is produced and
demonstrated through experiments.  .

Regards,

Tufail Abbas
