The singularity c'=c (equivalent to the singularity 2+2=5 in Big Brother's world) helps Einsteinians solve difficult problems. For instance, the observer/receiver starts moving towards the light source at (1/3)c:
http://www.einstein-online.info/spotlights/doppler Albert Einstein Institute: "The frequency of a wave-like signal - such as sound or light - depends on the movement of the sender and of the receiver. This is known as the Doppler effect. (...) In the above paragraphs, we have only considered moving sources. In fact, a closer look at cases where it is the receiver that is in motion will show that this kind of motion leads to a very similar kind of Doppler effect. Here is an animation of the receiver moving towards the source: (...) By observing the two indicator lights, you can see for yourself that, once more, there is a blue-shift - the pulse frequency measured at the receiver is somewhat higher than the frequency with which the pulses are sent out. This time, THE DISTANCES BETWEEN SUBSEQUENT PULSES ARE NOT AFFECTED, but still there is a frequency shift: As the receiver moves towards each pulse, the time until pulse and receiver meet up is shortened. In this particular animation, which has the receiver moving towards the source at one third the speed of the pulses themselves, four pulses are received in the time it takes the source to emit three pulses."
In a world different from Divine Albert's world, if "four pulses are received in the time it takes the source to emit three pulses", and if the speed of the pulses relative to the source is c, then the speed of the pulses relative to the observer/receiver would be c'=(4/3)c, in violation of Divine Albert's Divine Theory.
In Divine Albert's world c'=(4/3)c is impossible. Einsteinians regularly set to work to exercise themselves in crimestop. They present themselves with propositions - "Divine Albert said c'=c, yes we all believe in relativity, relativity, relativity", "Maxwell had said c'=c, yes we all believe in relativity, relativity, relativity", "Michelson and Morley had proved c'=c, yes we all believe in relativity, relativity, relativity" - and train themselves in not seeing or not understanding the arguments that contradict c'=c:
http://ebooks.adelaide.edu.au/o/orwell/george/o79n/chapter3.4.html "He set to work to exercise himself in crimestop. He presented himself with propositions - "the Party says the earth is flat", "the party says that ice is heavier than water" - and trained himself in not seeing or not understanding the arguments that contradicted them. It was not easy. It needed great powers of reasoning and improvisation. The arithmetical problems raised, for instance, by such a statement as "two and two make five" were beyond his intellectual grasp. It needed also a sort of athleticism of mind, an ability at one moment to make the most delicate use of logic and at the next to be unconscious of the crudest logical errors. Stupidity was as necessary as intelligence, and as difficult to attain."
So nowadays c'=c is an integral part of the spirit of our civilization. Like a tumor with many metastases, it cannot be removed: c'=c and the civilization will disappear some day simultaneously.
