Let $n $\underline {\textit{\textgreater }}\textit{ 2} be identical rockets: $R_{1}, R_{2}$\textit{, \textellipsis , R}$_{n}$.
Each of them moving at constant different velocities respectively
v$_{\mathrm{1}}$, v$_{\mathrm{2}}$, \textellipsis , v$_{\mathrm{n\thinspace
}}$on parallel directions in the same sense. In each rocket there is a light
clock, the observer on earth also has a light clock. All $n +$\textit{ 1} light clocks
are identical and synchronized. The proper time \quad $\Delta t'$
in each rocket is the same. Let's focus on two arbitrary rockets
$R_{i\thinspace }$and $R_{j} $from the previous $n$ rockets. Let's suppose,
without loss of generality, that their speeds verify $v_{i}$\textit{ \textless v}$_{j}$.
(1) In the reference frame of the astronaut in$ R_{i}$ it is like rocket$ R_{i}$is
stationary and $R_{j} $moves with the speed $v_{j}-v_{i}$
. Therefore the non-proper time interval as measured by the astronaut in$ R_{i}$
with respect to the event in$ R_{j}$ is dilated with the factor$ D(v_{j}-v_{i})$
, i.e. $\Delta t_{i.j} = \Delta t'D(v_{j}-v_{i}),$and rocket $R_{j} $ is
contracted with the factor $C(v_{j}-v_{i})$
$,$ i.e. $L_{j} = L_{j}^{'\thinspace }C(v_{j}-v_{i})$
$. $(2) \quad But in the reference frame of the astronaut in $R_{j} $it is like rocket
$R_{j} $is stationary and$ R_{i}$ moves with the speed
$v_{j}-v_{i}$
in opposite direction. Therefore, similarly, the non-proper time interval as
measured by the astronaut in$ R_{j}$ with respect to the event in$ R_{i}$ is
dilated with the same factor$ D(v_{j}-v_{i})$
, i.e. $\Delta t_{j.i} = \Delta t'D(v_{j}-v_{i})$
$,$ and rocket$ R_{i\thinspace }$is contracted with the factor
$C(v_{j}-v_{i})$
$,$ i.e. $L_{i} = L_{i}^{'\thinspace }C(v_{j}-v_{i})$
$. $But it is a contradiction to have time dilations in both rockets. (3)
Varying \textit{i, j in \textbraceleft 1, 2, \textellipsis , n\textbraceright }
in this Thought Experiment we get again other multiple contradictions about
time dilations. Similarly about length contractions, because we get for a
rocket $R_{j}$, \textit{n-2} different length contraction factors:
$C(v_{j}-v_{1})$
$, C(v_{j}-v_{2})$
\textit{, \textellipsis , C(v}$_{j}-v_{j-1})$
$, \quad C(v_{j}-v_{j+1})$
$,$ \textellipsis , $C(v_{j}-v_{n}) $
simultaneously! Which is abnormal.
