Object: Speed of Light: A universal Constant?
SR says that the speed of light is a universal constant.
Questions:
Why a clock second used to define the speed of light is not an interval of
universal time??
Why does SR say that a clock second in one frame does not correspond to a
clock second in another frame when the speed of light is a universal
constant??

Because the invariance of the speed of light requires that space and time not
be invariant. So even if I'm moving at 0.99*c, I will still measure the speed
of light from a pulse you send to me as being 2.998 * 10^8 meters per second.
It will certainly be Doppler shifted, though.
I fail to see the problem over which you apparently are tearing your hair out.

Doppler shifting is due to light arriving at the observer at different
speeds.

That's becasue you failed to recognize that Doppler shift is due to varying
speed of light.

Wormy is a runt of the SR experts.
Definition for a runt of the SR experts:
A moron who thinks that SR is a religion. An idiot who doesn't
know the limitations of SR. A mental midget who can't comprehend
beyond what he was taught in school. An imbecile who follows
the real experts around like a puppy and eats up their ***** like
gourmet puppy chow. An ***** who will attack anybody who

The speed of light in vacuo relative to any inertial frame is a well
measured constant. It has been shown experimentally again and again and
has yet to be falsified. The speed of light in vacuo is independent of
th motion of the source or the observer.

The speed of light is measured to be constant because we arbitrarily assumed
that the Doppler shift is due to wave length change. If wave length is
assumed to be contant then the speed of light is different from different
sources.

Assume two orbiting stars, far away, with barycenter
motionless with respect to Earth. Assume they orbit with
speed of approximately 10^-4 c = 30 km/s (which is about
Earth's orbital speed), to make the math easy, and that
the nominal radiation is 588 nm (which happens to coincide,
or at least be close to, a sodium line).
Emissive: delta-lambda = 58.8 pm
SR: delta-lambda = 2.94 fm
I'd say that's darned obvious, assuming one can in
fact determine that the velocity is 10^-4 c (which is
a problem). This is admittedly a hypothetical example
but real-world examples abound -- the most cited one
around here appears to be PSR B1913+16, which has a nice
elliptical precessing orbit and goes 15 times faster at
periastron than Earth.

This assumption is already wrong. There is no object in the universe that is
motionless wrt the Earth. The Earth itself is in a constant state of
absolute motion.

Assume they orbit with
speed of approximately 10^-4 c = 30 km/s (which is about
Earth's orbital speed), to make the math easy, and that

I think you are missing the point. What I said is that any observed Doppler
shift from a distant source moving wrt the observer is due to different
speed of light and not due to the changing of the wave length.

All objects in the universe (including the earth) are in a state of absolute

vector component of B's absolute motion along the line joining A and B.

Oh, come on. My coffee cup is not moving with respect to the table. And
just because the *center* of the next galaxy happens to be moving with
respect to the *center* of this galaxy does not mean that every star in
that galaxy is moving with respect to our sun. I'll give you a simple
example. I'm driving along a road at 20 mph and I throw my Mickey-D's
French Fry wrapper backwards out the window at 20 mph. Is the wrapper
moving or not, and with respect to what?
I'll give you another example. Suppose I look at the relative motion of
all the dots painted onto a balloon that is inflating. But the balloon
is also resting on the table, and one of the painted dots is precisely
at the point of contact between the table and the inflating balloon.
Note that, as the balloon inflates, ALL of the dots are in a state of
relative motion, including the one at the point of contact. But if the
table defined zero velocity, there is one dot that is not moving, even
though it has the same relative motion status as all the other dots on
the balloon.
It is simply NOT an empirical fact that everything is moving relative
to everything else, and it is also thus an improper conclusion from
that that everything is in a state of *absolute* motion.
[Punchline: I'm not arguing with you that everything is in a state of
motion. For every object, one can choose an inertial frame where that
object is in motion, and since all inertial frames are physically
equivalent, there is no object that can be said to be absolutely at
rest. However, is it your improper logical jump that everything is
therefore absolutely in motion. Rather, the proper statement is that
there is *no such thing* as absolute motion or absolute rest. It is
simply not the case that every object in the universe MUST be logically
categorizable as absolutely at rest or absolutely in motion. Your

you would not know the true magnitude of B's absolute motion.

OK, and here is where your computational weakness is showing through.
First of all, your definition of observed relative motion is incorrect.
If I have a passenger on Train A and a passenger on Train B, and the
two trains are going in opposite directions at 45 mph each on adjacent

of their relative velocity along the line joining them is zero.
There are other problems as well, but let's take it one error at a

of

absolute

motion.


Yeah, but suppose that there is one object in the universe that has
zero absolute motion.


So??

So... then the relative motion of all other objects can be measured
with respect to the one whose absolute motion is known, and then you
would be able to determine the absolute motion of all other objects by
doing a vector addition, one pair at a time. Agree or no?



It is simply NOT an empirical fact that everything is moving

relative

to everything else, and it is also thus an improper conclusion

from

that that everything is in a state of *absolute* motion.


It is an emperical fact that everything is in a state of absolute

motion.

Reference please. The only empirical fact we have is that all

objects

are in a state of relative motion.


And relative motion between two objects is the vector difference of

the

vector components their absolute motions along the line joining them.

And how does that provide evidence that *everything* is in a state of
absolute motion?
I'll give you an example. Take a 1-dimensional system to make life
simple, with five objects, A, B, C, D, E.
The relative motion between A and B is 2 m/s.
The relative motion between B and C is 3 m/s.
The relative motion between C and D is -4 m/s.
The relative motion between D and E is -2 m/s.
The relative motion between E and A is 1 m/s.
All of the objects in this universe are in different states of absolute
motion. Prove that none of them can have absolute motion 0.
(Exercise: Show that (A,B,C,D,E) = (0 m/s, 2 m/s, 5 m/s, 1 m/s, -1 m/s)
is a solution of absolute motions that satisfies the above
relationships.)
(Exercise: Show that (A,B,C,D,E) = (-2 m/s, 0 m/s, 3 m/s, -1 m/s, -3
m/s) is also a solution of absolute motions that satisfies the above
relationships.)


Relative motion between two objects A and B is the vector

difference

of

their vector components along the line joining A and B.


[Punchline: I'm not arguing with you that everything is in a

state

of

motion.


Yes you are.

For every object, one can choose an inertial frame where that
object is in motion, and since all inertial frames are

physically

equivalent, there is no object that can be said to be

absolutely at

rest.


Precisely....every objerct in the universe is in a state of

absolute

motion.


However, is it your improper logical jump that everything is
therefore absolutely in motion. Rather, the proper statement is

that

there is *no such thing* as absolute motion or absolute rest.


Sigh...if there is no absolute rest that means that all objects

are

in a

state of absolute motion.


Nope, it's not one or the other. Absolute rest is an ill-defined
concept.


It is only an ill-defined concept for a naive SR religious nut like

you.
No, it is an ill-defined concept for *reality*. Nature abhors an
absolute velocity, as experimentally shown. QED demonstrates this.



It is

OK, and here is where your computational weakness is showing

through.

First of all, your definition of observed relative motion is

incorrect.

If I have a passenger on Train A and a passenger on Train B,

and

the

two trains are going in opposite directions at 45 mph each on

adjacent

tracks. At the moment where the two passengers are directly

across

from

each other (at their point of closest approach), their relative
velocity with respect to each other is 90 mph. However, the

component

of their relati
