Scientists at Sandia National Laboratories observed a fascinating phenomenon that’s similar to the T-1000 android from Terminator 2: Judgment Day. In their experiments, they pulled on small metal pieces rapidly.
At first, cracks appeared in the metal, but after about 40 minutes, something amazing happened—the metal reconnected and fused back together. This self-healing ability, called “cold welding,” could lead to advanced materials for machines, making them stronger and more durable, thus lasting longer. It’s a breakthrough with exciting possibilities for various industries.
