Oh for heaven's sake.
I teach graduate thermodynamics and also optical spectroscopy. There is no conflict between a constant speed of light and thermodynamics. Nor is there any evidence the speed of light has changed with time. In fact, there's ample evidence none of the fundamental physical constants have.
BTW before I was addicted to internet learning I was 'indoctrinated' in public schools 5-12 but also was an avid encyclopedia worm.
One problem with internet learning is that every crank these days has an internet page, and unless you have a way between discriminating between credible sources and hooey, you can 'learn' a whole bunch of things that just aren't true.
The funny thing is how society defines 'experts' yet they all are still full of fallacy and error that far outweighs whatever true knowledge they have attained - wouldn't you agree Mr. RWP?
Now, I think that's utterly crazy. Experts can be wrong, sure, but they are far more likely to be right than wrong. That's why they're experts.
You said you were a computer programmer/analyst. Would you say your errors far outweigh what knowledge you've attained? If so, why is anyone employing you?
I think it bc I'm willing to find, admit and correct my errors - something that I'm not sure the education system is willing to do...
Also I've always found learning easier when someone wasn't speaking/writing to me in such a condescending manner as is evident throughout most of your replies.
