Re: Length Contraction Fully Explained

xray4abc claims:
In classical mechanics was considered that there
exist signals of infinite speed and so all clocks
could be synchronized instantly in any place in
an IRF.

This is not possible, we know now.

So you finally agree that Galileo's clocks are
completely different from Einstein's.

However, your claim that this is not possible
is not provable.

It may indeed be possible even without those
imagined infinite-speed signals.

And when it becomes possible, we will at last
have correct time measurement because our clocks,
unlike Einstein's silly clocks, will be correctly
or absolutely synchronized.

xray4abc asks:
So, what is the problem then? Are you striving to
understand some basic things *the way they are*,
or just wanting" to be right" on an issue ?

The problems are as follow: We currently have no
means of making correct time measurements or correct
length measurements. Therefore, we cannot make any
correct speed measurements, not even for merely
relative speeds, much less speeds through space.

Here are the physical causes of these problems:

[i] lack of absolute synchronization

[ii] lack of proof that one's clocks are unslowed

[iii] lack of proof that one's rulers are
(physically) uncontracted

These three are the primary deficiencies of SR.
