Only if light speed is source dependent can physics be the same inside different inertial frames. And I really think this is the case because waitresses in cafes, servers inside train cabins
moving at 52 miles per hour, and stewardesses on a 747 flying at
534 miles per hour can pour a cup of coffee right into a cup without
spilling a drop so it can't be all that difficult for light to move with a velocity dependent of its source.

The way Dr. Su’s theory works is that light speed is “source dependent” only while light is traveling near the surfaces of astronomical bodies. That is because the light speed is regulated by the local gravity field at the bodies, and that field is moving through space with the body and the speed of the light is not influenced by any other body’s gravity field, until the light begins to get out of a solar system and enter deep space. In the deep space, its speed is regulated by the combined fields of all the stars in that vicinity of space.

Another way to think of it is like this: Light while traveling inside one galaxy will have an average speed (relative to the center of that galaxy) of approximately “c”, because its local speed in the galaxy is being regulated by all the local fields of that local galaxy.

But, billions of years later, as the light enters a completely different galaxy, that new galaxy will regulate the local speed of light to an average of "c” while the light is traveling inside it.

So, if the two galaxies are moving apart rapidly, the local light speed is about “c” inside the galaxy in which the light is traveling. Once the light leaves that galaxy and enters the strong field areas of another galaxy, its local speed is regulated by the fields of the new galaxy through which it travels.

If the second galaxy is moving at the speed of light relative to the first galaxy, the light is moving (relative to the first galaxy) through the second galaxy at the speed of light in that second galaxy, plus the speed of that galaxy away from the first galaxy.

Or, think of it this way: Sound is regulate in air by the properties of the air. If a pocket of air is moving through space at 600 mph relative to another pocket of air (such as in an airplane in the sky as compared to a house on earth), then the speed of sound in the airplane is “c”, relative to that moving pocket of air. But, relative to the pocket of air that is in the house on earth, the speed of sound in the airplane is “c” + or – the speed of the airplane, depending on whether the airplane is moving toward or away from the house.

Once the sound leaves the airplane, its speed is no longer regulated by the air inside the airplane, but its regulated by the air outside the airplane.

This is very simple classical Doppler theory, and light must work in a similar way. But, the local light propagating medium seems to travel around with astronomical bodies, just as the pockets of air travel around within moving airplanes.

There is no “ether wind” at the surface of the earth, according to Dr. Su, because the “local ether” at the surface of the earth is the earth’s own local gravitational field, which travels through space with the earth, just as the earth’s own atmosphere travels through space with the earth.

If you run a flag up a flag pole, you will not see any evidence of an 18.6 mps “air wind” as the earth moves around the sun, because the local air is not sun-based, but it is earth based. The “local ether” is not sun-based or universe-based, but is earth-based.

If the waitress on a train was pouring coffee on the open deck of a flat car that has no walls or roof, the coffee would react to a 60 mph wind and would not flow straight down into the cup, but it would flow in a direction toward the end of the train and it would miss the cup. So “inertia” is not the only factor involved. “Fields” are involved, and in the case of the coffee and the wind, the air acts like a field through which the coffee, waitress, and cup are moving.

<br />OK c-v and c+v can be used to do calculating rather than maintaining the speed of light as a constant. So, what is gained in doing this?

SR's postulate of a constant speed of light independent of source must result in contradiction with its second postulate, that physics is the same in all inertial frames, since the speed of light then would be c+v and c-v round trip measured inside an inertial frame moving at v relative to the vacuum. <hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">

The speed of sound is source independent. Sound speed doesn’t depend on the speed of the source. It depends on the material through which the sound waves travel.

If you consider that the “fields” of space, or, specifically, the “gravity fields” of astronomical bodies act as the “speed regulator” for light, then you will have the speed of light move at approximately “c” at the surfaces of astronomical bodies the size and mass of the earth.

If the bodies are more massive, the speed of light will be slightly slower at their surfaces (as explained in the 1911 Einstein gravitational redshift theory, and as shown in experiments by Shapiro).

In deep space, where the gravity fields are “blended”, the fields of deep space will regulate light speed to the motion orientation of those fields. For example, if the fields of the bodies inside a galaxy are revolving around the center of the galaxy, then light beams moving from star to star and star to planet will also revolve around the center of that galaxy, since their speeds are being regulated by the fields that are contained inside the galaxy. This is why we do not have to consider the revolution rate of the solar system when we aim radar beams at planets like Venus or Mars. This is why we don’t have to consider the galaxy revolution speed of the sun when we aim satellite dishes at satellites or distant spacecraft.

For more on this theory, go to Google and type in:

local ether Su

And you will find all the papers about this “local ether” theory that have been written by Professor Su.

I think the “vacuum” you are talking about is what Dr. Su calls the “gravity fields” of space. They travel with a body, near the body, but many are “blended” with the fields of other bodies in deep space.

What I meant was "source frame velocity dependent" where source frame is a set of inertial coordinates that includes the medium
and the detector for wave propagation theories of light (e.g. everything inside a moving car, train,
or airplane).

If sound or light is depicted as wave motion then
obviously its speed through space depends on how fast energy is transfered between the molecules in the medium. But more
than that, if the medium is itself moving through space, the waves
traveling through the medium should also obtain the velocity of the medium through space, and the speed of the waves are c relative to the motion of the medium through space (i.e. c+v in the direction of the medium and c-v against the motion of the medium). If sound or light is depicted as particle phenomena, then it gains the velocity of the source to travel at
c with respect to a detector in the same inertial frame, in a vacuum.

Just by adding v+c or subtracting c-v will not change the speed of light as you seem to suggest(or am I wrong here). The speed of light is the speed limit on all these mattters. By adding or subtracting v from c you get a redshift not an acceleration of the speed of light.

Yes it does when measured with respect to a frame at rest in a vacuum. Assume you are squatting or standing "still" on Earth. Call
your velocity with respect to the Earth inertial frame c. Now if you
were then transported to an airplane flying at 543 miles in the easterly direction with respect to a ground observer, your velocity
in your new frame is still c- i.e. you are still standing or squatting "still", but inside an airplane. This c however has a value of c+v or c-v with respect to the coordinate system of
the observer on the ground which we have taken to be the rest frame
to compare all motion. Finally, assume your speed in your frame represents the speed of light with respect to the rest frame. Obviously then, it is different when you are on the plane (c+v and c-v) then when you are on the ground (c), even if the value c is the same for all inertial frames when measured using the coordinates of your inertial frame to measure your velocity through space. That is the effect of source dependency.

All the chatter in the world is not going to change to speed of light. What you get by adding or subtracting velocity to the speed of light is the redshift. By doing this there is no time problem-no twins to ponder or sticks to measure. That is the real advantage.
