Now, before things get out of hand: they clocked neutrinos moving faster than the speed of light, and are now encouraging others to recreate the experiments and see what happens. They aren't throwing a party and saying they've changed physics. However, this could be the beginning of changes and furthering of physics on a large scale, if confirmed.
The biggest discoveries in science don't come with a shout of "eureka!", they come with a raised eyebrow and a muttered "hang on...that's odd...check this out."
