Now, I do not expecy you to understand a bit of what I wrote. I expect
another ad hominen attack. However I have to tell you to read the
original paper by Einstein and notice his notorious mistake.

Notorious amongst the naive and crackpots

The uses
c-v and c+v to conclude that simultaneity is relative to a reference
frame.

That's right .. its not a mistake, however

Explain why do you think is not a mistake.

However, he has already accepted his light postulate.

That he has .. that use of c+v and c-v does not contradict the postulate

It does. Explain why it does not. Nobody will take your word for it..

The postulate says that light travels at c in every frame. That is
relative to a set of coordinates where observers at rest in the frame
are not moving. If an observer is moving relative to the coordinate
system then it is not his rest frame and he does not use that
coordinate system to make his measurements.

Let us attach then an inertial frame to the observer.

The observers at rest measure light to travel at c relative to
themselves and a moving observer to travel at v. The stationary
observers can calculate the closing speed of light with the moving
observer to be c+v or c-v without violating the postulate.

Your statement does not make any sense. What is a "closing speed of
light with the moving observer"? Uou are setting up a straw man.

Armchair philosopher --- closing speed --- crash!

The moving
observer doesn't care what these observers measure, he uses his own
coordinate system, which includes differently synchronized clocks, to
measure the speed of light to be c in his rest frame.

Everubody accoridng to SR should measure c. Regardless of where, when,
what or who.

Armchair philosopher --- closing speed --- clash!

So both frames measure the speed of light to be c as the postulate
says. The closing speeds of c+v and c-v were calculated, not directly
measured.

hahahahahahahaha.  Calculated? Do you really want to say that you can
calculate in SR things that violate its postulates? No wonder you get
so many paradoxes.

Armchair philosopher --- closing speed --- smash!

You are being totally stupid.

he was a
very confused man about his own theory.

The one showing confusion here is yourself, when you cannot see that there
are two different concepts involved

State the two different concepts clearly.

Direct measurement of a speed relative to yourself vs a calculated
speed relative to something moving.

Listen, regardless of speed v (constant of course) the speed of light
must be c. This is an axiom of Relativity. If you assume it is v-c, ot
v+c, if you calculate it to be v-c, or v+c, it means the postulate was
violated.

Armchair philosopher --- closing speed --- splash!

Do you understand that? If you do not, and if you are making up such
ridiculus stories to try to convince people otherwise in an attempt to
cover up such inconsistenceis, the only onbe you are folling is
yourself?

Folling?
With his fungure, or with his fingure?

He showed that simultaneity is
relative in 3-D space and time if speed of light is source dependent.

No .. if is it source independent. Please try to keep up

Are you insane? he has postulated light speed is not source dependent.

Source independence means it doesn't matter whether the source is
moving or not. Where the wavefront is still depends on where the
source was when the light was emitted, as determined in the
coordinates of the frame in which the measurement is being made. IOW
the light doesn't travel to you at c+v just because the source is
moving toward you.

Now, you revert back. Is this t3echnique taught some place ot it is a
way of mental masturbation?

It's a futile way to try to teach an imbecile. Doesn't work :-)

Now you tell me that c+v and c-v can be used to claim source
independence.

Yeah, the closing speed of light with the moving source is c-v as
measured in the coordinates of my rest frame, but not his.

Light moves at c, regardless of speed of source and in all inertial
reference frames. Unless this is the cases, the Minkoswki spacetime is
not valid.

Let's go but to the initial atatchment of an inertial reference frame
to the moving observer. Light speed is c both for the observer and for
the stationary frame (source independence).

In other words, your selective application of the postulate to enforce
a certain preconcieved result, invalidates the theory and makes it
inconsistent.

Armchair philosopher --- closing speed ...
WHAT - DID - I - TELL - YOU?

Does it hurt, being this stupid?

I hope you did not run out of pill and I hop[e you get well soon. I do
not hate you like you do hate me.

Closing speed greated than c when the thing that is moving, STUPID, is
light, violates the light postulate.

No, it doesn't, Mike. The light postulate refers to *relative* speed,
not closing speed. Big difference.

Closing speed applies to v < c
and can never be > c for light because it would violate causality
(which it does the why SR is formulated).
