Ever wondered why a nuclear reactor can pulse—and why it sometimes glows like something out of sci-fi? ⚡️ What you’re seeing isn’t magic… it’s physics putting on a light show. Inside a reactor, atoms (usually uranium) are splitting in a process called fission. When that happens, they release energy and fast-moving particles—especially electrons. Now here’s where it gets visually wild: when those electrons travel through water faster than light can move through that same water (not faster than li
