But till now, nobody
has indubitably proved that length contraction is real.

Of course not. The "length contraction" is to
be found in the near Maxwell fields. Not in
the ambiguity that can be created with a
archaic model of light propagation.

<<when we calculate the contribution of charges and
currents at position ${\bf r}'$ to these integrals
we do not use the values at time $t$, instead we use
the values at some earlier time
$t-\vert{\bf r} - {\bf r}'\vert/c$. What is this
earlier time? It is simply the latest time at which
a light signal emitted from position ${\bf r}'$
would be received at position ${\bf r}$ before
time $t$. This is called the retarded time. >>

PD's patience is exceeded only by your own.
Let's take up a collection to buy a new
keyboard for him.

....Tho a bigger video monito might solve his
problems altogether. ;-)
