Metal Fuses in Space Without Heat | NASA’s Cold Welding Phenomenon Explained #ColdWelding #NASA #SpaceScience #StrangePhysics #SpaceFacts 🧠 SEO-Optimized Description (Detailed & Engaging) It sounds impossible, but in the vacuum of space, metal can fuse instantly—without heat, glue, or welding tools. This phenomenon is known as cold welding, and it occurs when ultra-clean metal surfaces touch in the absence of air, dust, or moisture. In space, atoms on metal surfaces can bond directly, creating
