Some things happen by chance!” This is an interesting explanation of virtual particles. It is something to consider when you hear the claim “Virtual particles are proof that something can come from nothing.” http://profmattstrassler.com/articles-and-posts/particle-physics-basics/virtual-particles-what-are-they/ An excerpt: “The best way to approach this concept, I believe, is to forget you ever saw the word “particle” in the term. A virtual particle is not a particle at all. It refers precisely to a disturbance in a field that is not a particle. A particle is a nice, regular ripple in a field, one that can travel smoothly and effortlessly through space, like a clear tone of a bell moving through the air. A “virtual particle”, generally, is a disturbance in a field that will never be found on its own, but instead is something that is caused by the presence of other particles, often of other fields.” Comments are closed.
