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.
