Bad answer.
You said it was well defined, and when asked for a definition
you give an ill-defined "best you can do". Perhaps you should begin
by defining 'coordinate' and 'system' separately.
What exactly is a coordinate?

What exactly is a number?

Analyze:
The absolute length comes into being because the time for
light to get from A to B is L / (L/t), where L/t is lightspeed.

L/t is not lightspeed. v_l is lightspeed. (v_l can be any value at all.)


Reducing to plain English:
The absolute length comes into being because the time is t.

This is your concept of "well-defined", is it?

Length depends on time in SR.

That's the problem.

"If we place x'=x-vt, it is clear that a point at rest in the system k must
have a system of values x', y, z, independent of time. " - SR.
Length does not depend on time in SR.
Do you see any contradiction here ... erm... fuckwit?

Plenty. The length is obviously absolute and unchangeable, except for
the (-tvx, -tvy, -tvz) for some vx, vy, vz (in a four-dimensional
spacetime coordinate system). or -vt (in a two-dimensional system).

Therefore SR is bunk, Planet Androcles exists, and H. Wilson's
luminiferous aether are correct.

Yes, it works fine.

Special Reality. It's there, but it doesn't work.

If we all decided to have a piss-up and chose a brewery for a venue,

Not my speciality. In any event, SR has not been disproven by you;
you'll have to try a little harder.


Androcles.
