How can the above two pillar stones of
Physics survive in view of time dilatation
(and time not being absolute after all)?

Because "absolute" is something
artificially impressed by *human*
expectation.

Unfortunately for you, you cannot solve
any Physical problem without that "absolute
fixed frame of reference".

I do it all the time. "substitution of
variables", "selecting a coordinate frame",
everything starts with "the difference
between here and there".


In theory that's fine.
In practice you're bond by the experimental
set up, made here on Earth, or nearby.


Or light sources 1.7 Gy away. Still all these things are relative to
"here and now".

Put the theory written on paper aside.
Look only for real world experiments.


They are only experiments if Nature is challeged / queried.


Does Hubble red shift (the expansion of the Universe)
hold as a good Nature challenge? For instance.


If you're in trouble to find where the absolute
frame of reference is, call me and I'll tell you.


We've got 100+ years of experimental results, and we have moved more than
946 billion miles in that time. "Here and now" does not really work as an
"absolute frame".

So I am calling you.


Take Pioneer 11, for example.
Pioneer 11 experienced, during almost ten years, a perfect
constant acceleration (a perfect straight line) directed towards
the Sun, whose mearured acceleration is exatly the
acceleration of Hubble constant.
Hubble constant is an acceleration, since it's a velocity taken
per a distance (Megaparcec). So that, we know that during
the time it takes for light to travel that distance (1 Mpc) the
velocity of celestial bodies increase 85 m/s - we have a "dv".
So the time it takes for light to travel the distance of 1 Mpc
can be calculated - it will be our "dt".
dv / dt = 85m/s / 1Mpc = Pioneer 11 acceleration.
It's a perfect match.

Don't tell me it was blueshift.
I know it was blueshift.
What else could it be?
