The postulates of Einsteins relativity are:

I agree that this statement is perfectly true.

2. The speed of light is the same for all inertial observers.

This statement is totally false. The speed of light APPEARS to be the same in all inertial frames of references, but in fact it is really not. This is the key difference between accepting and refuting the aether, and unfortunately physics went down the wrong path. When an observers absolute speed increases, its clocks begin to slow down and its length contracts in the direction of its motion. This causes them to be misled when measuring the speed of light. The slower time and contracted lengths cancels the difference in speed between it and the light, so the lights speed appears to be always constant. It is that simple.

This explanation falls flat on its face through a couple of simple examples.

Start with a rod 299,792,558 m long. Light will take exactly 1 sec to traverse its length while at rest.

Start it moving at 0.866c. At this speed, its length would contract to 1/2 and its clock will run at half speed.

So let's say that a light beam is fired towards the front of the rod at the instant the back end passes the point from which the beam is emitted.

Now according to your explanation, the light is

*really* traveling at 1c-.866c =.134c relative to the rod, but because of length contraction and time dilation, he measures this as 1c.

Now taking the rod's length contraction into account, the light will take 149,896,294/.134c = 3.73 sec to travel from the back to front of the rod.

Considering that the clock of an observer traveling with the rod would be running 1/2 as fast, he would measure the light as taking 1.866 sec to travel from end to end. Since, by his measurement, the rod is 299,792,588 m long, then he would measure the speed of light relative to himself as being 0.536c not 1c.

It gets worse if we fire the beam from front to back, because now the back end is rushing to meet the beam and the relative velocity between beam and rod is 1.866c, the time it takes for the beam to go from front to back is 0.268 sec, which the observer on the rod measures as 0.134 sec, meaning he measures the light as moving at 7.46c relative to himself not 1c.

So you can't just say that the length contraction and time dilation caused by the absolute motion of the observer causes him to measure a passing beam of light's speed as being c, as it does not.
