Einstein is still ok


Remember back in September when I wrote about faster-than-light neutrinos? Scientists at CERN running the OPERA experiment had claimed to record neutrinos arriving at a detector 60 nanoseconds faster than they would have if they had been travelling at the speed of light. There has been a ton of skepticism around this result, and now, it turns out, the discrepancy in the arrival time is probably due to a faulty connection between the GPS unit and the computer.

Anyway, the team will have to rerun the experiment to make sure that this is indeed the source of that error, but it looks like Einstein's Theory of Relativity is still valid. Nothing can travel faster than the speed of light. If you want to read more about this, check out this Wired article, this Science Insider article, or this Telegraph article.
