The Atlantic has the latest on a breaking news story that began a few billion years ago: For the first time, astronomers have traced a neutrino back to its birthplace, billions of light-years across the universe.. “Neutrinos are everywhere, and they pass through everything, all the time. This includes your little place on Earth: your home, your body, the membranes that enclose the cells that make you you. About 100 trillion neutrinos pass through your body every second. You can’t feel them, but perhaps you can feel some wonder in knowing they’re there, just passing through, a toll booth on an invisible journey without an end.” (I don’t really understand this story, but I’m sharing it anyway. In other words, I’m doing what everyone else on the internet does…)
