To be fair, they didn't actually think they'd discovered faster than light travel. They basically went "uhhhh, we double-checked everything and our numbers work out but we're pretty sure this isn't faster than light; here's our paper, can someone please point out wtf we screwed up?

A single incorrectly installed fiber optic cable, and an out of spec clock. It wasn't even a bad cable, just not inserted completely correctly. https://en.wikipedia.org/wiki/Faster-than-light_neutrino_anomaly https://en.wikipedia.org/wiki/Faster-than-light_neutrino_ano... EDIT: A much better detailed analysis of the failure including pictures of the cable, https://profmattstrassler.com/articles-and-posts/particle-physics-basics/neutrinos/neutrinos-faster-than-light/opera-what-went-wrong/ https://profmattstrassler.com/articles-and-posts/particle-ph...
- credit_guy 6y agoThis is a bit of revisionist history. The way the "discovery" was announced was slightly subdued, they called it an "anomaly", and added the caveats that it could be due to some errors, but they also stated that the "deviation of the neutrino velocity from c would be a striking result pointing to new physics in the neutrino sector". So pretty much, we are not 100% sure, but if this is correct, this is revolutionary. That's not exactly the tone of someone who asks the larger community to assist with a debugging exercise. And the recent announcement repeats the same pattern. "This could be due to some equipment malfunction, but if not, then this is big".
