O'Barr comments:
What a perfect post you wrote. Thank you!
It was way too long. So I am breaking your post into
part A and part B.

Part B:


Your post was too long.
I will respond to only a couple of points.


O'Barr comments:
Do not play games. In LET measurements are an
absolute necessity. But they are not king. The king
is man, and his intellect.
We know what is going on,
and we know how to properly interpret what is
measured.

That is a BAD idea, and more over, it is completely unscientific. I
don't know where you were trained to do science, but to say that
intellect rules over measurement in science is precisely horse behind
the cart.

If man is not able to properly interpret
his measurements, then these measurements are
useless. No measurement can have any meaning exact
as man learns to properly consider them.

You have it in your head that if some object (a
photon or not) is moving at some speed v relative
to some inertial reference frame, and that if
another reference frame is moving at speed u
along the same axis relative to the first frame,
then the
speed of the object relative to the second
reference frame MUST be (v +/- u).

O'Barr comments:
Well, let me tell you what I believe. If all
your observations are in the same frame, using the
same tools, velocities all add up in a vector
fashion. Do you disagree with this?
PD <TheDraperFam...@xxxxxxxxx> wrote:
Yes, I do. It is counter to experiment.
We have long believed that velocities simply add
like vectors. We have believed this because, for
nearly everything we applied it to for hundreds of
years, it seemed to work. However, it is WRONG.
Velocities do not add like vectors. The
prescription to add them like vectors is an
excellent *approximation* as long as the vectors
are small compared to the maximal velocity, c. But
it is an approximation only.

O'Barr comments:
O.K. Just so we understand each other a little
better, let us take Einstein's train example. This
train, in the frame of the track, is going at a
velocity of v. Light in the frame of the train,
going in the same direction as the train, is going
past the train at a velocity of c-v, according to
those in the frame of the track.

No, that is INCORRECT. That is the *classical* surmisal and it is
wrong. I don't know where you got the impression that it is c-v.
Someone who uses his intellect AND his measurements understands
completely that the light is going past the train at
(c-v)/(1-cv/c^2) = c.
There is simply NOTHING other than *habit* and *assumption* that tells
you that it is c-v.
There is no *measurement* that tells you it is c-v.
There is no sound, logical argument about the way that velocities
combines that tells you that it is c-v.
c-v is simply incorrect.

Are you saying that
this velocity of light relative to the train, as
measured in the frame of the track, is not exactly c-
v? If it is not exactly c-v, please tell me the
exact velocity. Thanks!
