phase velocity can, but group velocity can't...

I SAID it was naive and the BRIEF reading had me still thinking of a

yikes ;-)
More in the same naive vein: I seem to recall that there is a measurable

has super-luminal velocity: is it phase velocity vs group velocity?
Gamma rays have wave properties too of course! :-)
