I’m not sure why we should be freaked out about the speed of light being broken. Yes, it “invalidates” Einstein’s theory of relativity. But it does so in the same sense that relativity “invalidated” Newtonian physics: that is, for a tiny sliver of edge cases that mostly apply just to theoretical physics. Just as bridges didn’t start to collapse after Einstein, nuclear reactors are not going to begin exploding if it turns out to be true that neutrinos travel slightly faster than the speed of light. EVERYBODY CALM DOWN!
