So recently, I was in a conversation with some people and the question “What has particle physics ever done for us?” came up. So every day for the next until I get distracted by something else, I will post one tangible thing particle physics has produced.
Neutrinos are small (almost mass-less), weakly-interacting particles. They also happen to move at approximately the speed of light. Thus, if we were to send information using neutrinos, it would its destination very quickly and without being distorted by anything. By comparison, radio waves lose strength over distance and they can’t pass through the earth (due to the high metal content)
