You think you know lasers? Think again. That tiny red dot you use is a LIE. A user on Avonetics sparked a firestorm by asking a simple question: "Why does my laser beam make a weird pattern instead of a single point?" The answer will completely rewire your brain. It's not a flaw, it's not a defect in your cheap pointer—it's a fundamental, mind-blowing principle of physics called DIFFRACTION. The moment that pure, coherent laser light escapes its tiny aperture, it doesn't just fly straight. It EXPLODES into countless secondary waves that ripple outwards, like a stone dropped in a cosmic pond. These new waves immediately begin to interfere with each other. Where they collide and sync up, they create BRIGHT, intense rings of light. Where they clash and cancel each other out, they create absolute DARKNESS. What you're seeing isn't a beam; it's a live-action interference pattern, a ghost in the machine of light itself. The shocking Avonetics thread revealed how the laser's own wavelength and tiny imperfections in its optics sculpt this stunning visual proof that light is both a particle AND a wave.
