Easy arguments against the Bible, and religion as a whole

[Jackalope]

Light, which normally travels the 240,000 miles from the Moon to Earth in less than two seconds, has been slowed to the speed of a minivan in rush-hour traffic -- 38 miles an hour.

Yes, those are special cases where light has shown to slow. Any evidence that it has increased in speed (as would be required for the young-earth argument to hold water)?

Also - if you're making a young-earth argument, there's other evidence you'll need to deal with aside from the speed of light. We even have a thread for it.

I looked at your first link (the one from Optics and Photonics) and it's pretty thin on details. Before I could seriously consider this line of evidence, I'd need to see a bit more detail. Sanejouand's speculation (if true) that 'c' has slowed over time would turn modern physics on it's head, and so I think it's reasonable to expect more detail. I note that while the article does have references, none of them are from the person making the claim. Has this been published in a peer-reviewed journal? Without peer review, all I see is a vacuous claim that can't be taken seriously as scientific evidence. If there's more, by all means present it.
