Remember in September when neutrinos were observed moving faster than the speed of light, potentially overturning everything we thought we knew about physics? It was met with all sorts of skepticism and dubiety, so the physicists decided to replicate their experiment and take new measurements.
Well, the new results are in, and they confirm the original findings. The improved version of the experiment, which fired bunches of neutrinos in three-nanosecond bursts through 450 miles of solid rock, was repeated 20 times and reinforced the controversial result.
The next step is for other labs, such as Japan's T2K, to repeat the experiment. Only then can we start rewriting the textbooks.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
