I just had a flashback to an applied electromagnetic course I took a few years ago. I believe we were learning possibly about waveguides (maybe) or something, but there appeared a phenomenon in the math that made it appear as if the wave was traveling faster than C.
When asked about it, the professor said this is a sort of 'trick' because actually the information was not traveling faster than C, so it is allowed by the universe.
I sort of took it for granted at the time and accepted his explanation (it's not the first time I can remember hearing of it) but if anyone knows what I'm talking about I would be grateful to be reminded, now that I have developed a taste for information theory.
