The theory of relativity claims that the motion of physical objects
cannot exceed a speed of 300,000km/sec. However, we know from
experience (e.g. equatorial rocket launchings, multistage rocket
vehicles etc) that the final velocity of objects is their starting
velocity plus their own velocity. There is no reason to believe a
maximum applies.

A spaceship travels away from star X at a speed of 300,000km/sec (v1).
The spaceship fires off a rocket from its nose. It has a velocity of
100km/sec (v2). The speed of the rocket is now 300,100km/sec (v1+v2),
i.e. the rocket travels away from the spaceship at 100km/sec and star
X at 300,100km/sec. Special relativity however demands it can only be
300,000km/sec, the maximum velocity allowed by the theory. This is
only possible if at the moment of the firing the speed of the rocket
is reduced to zero or the speed of the space ship is reduced to
299,900km/sec or a combination of the two. SR cannot provide evidence
or even a theory to explain how the reduction is possible or occurs.
It relies on the mathematical formula obtained by Fizeau (1819-1896)
in his experiments about the propagation of light through flowing
water in 1851. The formula is v’=v+w/(1+vw/vv). AE, citing Fizeau,
proposed this formula for the addition of velocities of all physical
objects (AE, ‘Relativity: The Special and General Theory’, Chapter 13,
Methuen & Co Ltd 1920). AE claimed it paralleled his illustration of
relativity in the train example he used to prove special relativity.
It has been swallowed by science ever since.

No...Not by "science".
Perhaps by those with need to decieve themselves or others.

<<special relativity was always a provisional theory
with recognized epistemological short-comings.
As mentioned above, one of Einstein's two main two
reasons for abandoning special relativity as a
suitable framework for physics was the fact that,
no less than Newtonian mechanics, special relativity
is based on the unjustified and epistemologically
problematical assumption of a preferred class of
reference frames, precisely the issue raised by
the twins paradox. Today the "special theory"
exists only (aside from its historical importance)
as a convenient set of widely applicable formulas
for important limiting cases of the general theory,
but the phenomenological justification for
those formulas can only be found in the
general theory. >>

<<for sufficiently large $v<c$ we obtain $\Delta t'<0$: i.e.,
there exist [imaginary] inertial frames in which cause and effect
[] appear [] to be reversed. Of course, this is impossible in
deterministic physics. It follows, therefore, that information
can never appear to propagate with a superluminal velocity in any
inertial frame, otherwise causality would be violated. >>
