"The experiment showed that it is possible for light to travel at a slower speed even in free space - and Padgett and his colleagues did it at the scale of individual photons. (...) To the researchers' surprise, the light continued to travel at the slightly slower speed even after leaving the confines of the mask. (...) University of Rochester physicist Robert Boyd, while impressed with the group's ingenuity and technical achievement, calmly took the news in stride. "I'm not surprised the effect exists," he told Science News. "But it's surprising that the effect is so large and robust." His nonchalance might strike non-physicists as strange: Shouldn't this be momentous news poised to revolutionize physics? As always, there are caveats. When it comes to matters of light speed, it's important to read the fine print.. In this case, one must be careful not to confuse the speed at which light travels, which is just a feature of light, with its central role in special relativity, which holds that the speed of light is constant in all frames of reference. If Galileo measures the speed of light, he gets the same answer whether he is lounging at home in Pisa or cruising in a horse-drawn carriage. The same goes for his trusty assistant. This still holds true, centuries later, despite the exciting news out of Glasgow last month."

So light is slowed in a vacuum but this is not "momentous news poised to revolutionize physics"? No problem for Einstein's relativity? Einsteinians? Have you been practicing crimestop for half a year already?

"He set to work to exercise himself in crimestop. He presented himself with propositions - "the Party says the earth is flat", "the party says that ice is heavier than water" - and trained himself in not seeing or not understanding the arguments that contradicted them. It was not easy. It needed great powers of reasoning and improvisation. The arithmetical problems raised, for instance, by such a statement as "two and two make five" were beyond his intellectual grasp. It needed also a sort of athleticism of mind, an ability at one moment to make the most delicate use of logic and at the next to be unconscious of the crudest logical errors. Stupidity was as necessary as intelligence, and as difficult to attain."
