Albert Einstein Institute: "One of the basic postulates of special relativity: The speed of light in a vacuum is the same for all observers drifting through gravity-free space (more precisely: for all inertial observers). In particular, its value is
independent of an observer’s motion relative to the source of the light." https://www.einstein-online.info/en/explandict/constancy-of-the-speed-of-light/
Physicists clearly see, e.g. here https://youtube.com/watch?v=bg7O4rtlwEE, that the frequency and the speed of the light pulses vary proportionally for the moving observer, in accordance with the formula
(frequency at observer) = (speed of light pulses relative to observer)/(distance between pulses)
Yet physicists believe that only the frequency varies - the speed of the pulses relative to the moving observer gloriously remains unchanged. Ignatius of Loyola explains:
Is this true? No. Is it a logical consequence of special relativity's postulates? No again. The postulates entail something quite different: either clock, stationary or moving, runs slow as judged from the other clock's system.
So the statement is non sequitur in special relativity but since the founder of the church has made it, faithful followers should teach it diligently:
Richard Feynman: "Now if all moving clocks run slower, if no way of measuring time gives anything but a slower rate, we shall just have to say, in a certain sense, that time itself appears to be slower in a space ship." http://www.feynmanlectures.caltech.
