Title: MPH Question Post by: RED-DOG on January 26, 2015, 01:47:44 PM If Celtic were made of glass, would it take light longer to pass through him or go around him? (I agree that both are daunting tasks)

Thanks for the link. i read today that this entire experiment started by two guys having a beer and deciding that it would be cool if they could show c(vacuum) was a limit, not a constant. 2 years later they demonstrated it. pretty cool! also - re xkcd book.
