Guys.
I want in on this light debate but have got to go away for a week. Don't say anything too interesting while I'm away, and I'll get back to you on it. Just quickly:
Is c changing?
To understand this properly I think it's important to realise just how big a statement this is. The constancy of light in a vacuum is the underlying axiom of 20th century physics. It's hard to explain just how much it would mean if somebody proved it was changing. Name a modern area of physics, and I guarantee that somewhere in the carefully sculpted maths behind it, the constancy of light will have been assumed, explicitly or not. [note by assumed I do not mean forgotten or ignored].
Put it this way. If somebody proved c was changing, it would be the BIGGEST discovery ever made. Almost, but not quite, like proving that 1 + 1 doesn't equal 2. It would be on the national news, and in the international papers. This is why it's hard to put any real faith in the claims of the links you have made. I will however read them when I get back, but the evidence they purport to have uncovered will have to weigh against the incredibly huge amount of proven, fantastically reliable and ultimately beautiful science that requires light's constancy.
Anyway, I don't hold with this "God is changing the laws of Physics as he goes along malarkey". Changing nuclear decay rates and decreasing the speed of light alludes to a God of deception and lies. And this is WRONG.
Oh, and could somebody link to some papers on this subject that have no religious motives? Thanks, and God Bless
