JE:-
All of Newtonian mechanics depends
of mass and time as abolute and not
relative _assumptions_. This means that
mass can be partitioned but only
mass can add or subtract mass
(similarly for time).

Each expression can only alter m or t
using additions or deletions of m and t.
For t, only additions are valid.
Employing -t is logical but not rational.
This is because a maximand cannot be negative.

JE:-
The above simply proves that EK is
indeed, a competent mathematician but
not competent scientist.

Jets are not the only objects
that can have forces applied to them
where the loss of fuel has nothing
to do with the logic discussed, anyway.

If you just throw a stone its mass must
remain a constant otherwise Newtonian
Mechanics stands refuted. Einstein
proved this was indeed, the case.

JE:-
The above does not matter in any way to
the argument that at least one constant
that represenets a maximand value must
exist for physics to be rational.

JE:-
EK's argument remains irrational.
Originally, the only way you could "established that
the speed of light is the same for all observers"
was to establish that c remains the _maximal_ velocity
of light in a vacuum for observers. Originally,
no way existed of putting different observers into
large enough velocities or measure the tiny time dilation
at different velocities for many different observers. All
that could be done is prove that c did not change with
a supposed aether as Newtonian Mechamics predicted
that it must otherwise Newton stood refuted.

JE:-
In simple terms all the Galileian
transformation means is that
Galileo reversed cause and effect
by suggesting the sun was stationary
and not the earth. In effect he simply
transformed the stationary position
of the sun relative to the earh as
a new maximand. Previously the stationary
position of the earth had been a
maximand so he reversed their rational
postion within the same logical argument.
The same process applies to the transformation
of Newtonian physics to Special Relativity
theory. In Newton's view m and t were
maximands but c was just a variable.
In the transformation of Newton to
Special Relativity these were exactly
reversed: m and t became varaibles and
c a maximand.
