The discussion centers on the debunking of the "c-decay" hypothesis, which suggests that the speed of light (c) may have changed over time. Participants assert that all attempts to validate this hypothesis are based on cherry-picked observations and instances of intellectual dishonesty. Modern physics firmly rejects the concept of c-decay, supported by a lack of experimental evidence and substantial theoretical work demonstrating its impossibility. Key resources, such as the talk.origins article, provide comprehensive overviews of the topic.
PREREQUISITESPhysicists, science educators, researchers in theoretical physics, and anyone interested in understanding the validity of scientific hypotheses related to fundamental constants.
All such attempts to show the supposed 'c-decay' have involved the researcher cherry-picking observations in support of his hypothesis. In at least one case I've seen, the researcher committed deep intellectual dishonesty and actually reported an erroneous datum specifically to make it agree with his hypothesis.
Modern physics does not support c-decay, nor any mechanism that might support it. There is no experimental evidence that shows it happens, and a great deal of theoretical work that shows it cannot.
