So a neutrino runs into a tachyon in a bar…. Here’s a collection of interesting twitter snippets from physicists I follow on twitter about today’s neutrino webcastย announcing the surprising, and frankly unbelievable, results that the OPERA collaboration observed superluminal neutrinos.

Theย paper1 drops the potentially model shattering result in a dry

An early arrival time of CNGS muon neutrinos with respect to the one computed assuming the speed ofย light ย in vacuum ofย (60.7 \pm 6.9 (\text{stat.}) \pm 7.4 (\text{sys.})) ns was measured.ย This anomaly corresponds to a relative difference of the muon neutrino velocity with respect to the speed ofย lightย (v-c)/c = (2.48 \pm 0.28 (\text{stat.}) \pm 0.30 (\text{sys.})) \times 10^{-5}.

the important thing here being that the last number (v-c)/c is positiveย meaning v_{neutrino}>c according to their result.ย I haven’t watched the webcast myself, nor read the paperย beyond the abstract yetย so can only comment that I believe it must be systematics. That said it would be insanely interesting to be proven otherwise.

Finally, the following highlighted tweets are in reverse chronology, because, well…ย I’ve been here since the day after tomorrow, said the tachyon. What took you so long?
