Kudos to the ATLAS and CMS teams for actually observing [sort of] an elementary particle 133 times as massive as a proton–125.3±0.6 gigaelectronvolts according to CMS; ATLAS says it’s 126.5±0.6 GeV. I don’t think they’ll be hassling over the precise figure, especially since both come with a statistical probability range that encompasses the other. Fabulous. These observations are all the more incredible because the boson decays in about the time it takes for light to travel the diameter of a hydrogen atom’s nucleus! [updated the distance travelled by light in about 10 to the power of -25 seconds. Still rough, but closer to the truth than the length of your nose, which was what I had in the earlier version of this post.]
